Introduction
The best family office software in 2026 spans several categories: purpose-built accounting platforms like SumIt, investment and portfolio reporting tools like Addepar and Masttro, integrated wealth management suites like Eton Solutions and Archway, and GL-plus-operations platforms like Asseta AI and FundCount. The right combination depends on entity complexity, investment volume, reporting requirements, and how your team is structured.
In 2026, family offices have more software options than ever before, but that’s an entirely new experience. Just a few years ago, most teams relied on Excel or general-purpose systems like QuickBooks, forcing them to manage complex entity structures and investments with tools that weren't built for family office operations to begin with.
As the industry evolved, that gap became clear, and purpose-built vendors entered the space. Today, the market has matured enough that it no longer makes sense to search for a single platform that does everything. The prevailing approach in 2026 is what practitioners call the "best-of-breed stack": selecting the strongest platform for each functional layer — accounting, investment reporting, bill pay, data aggregation — and connecting them through native integrations.
This guide covers where each platform fits within that landscape, with particular depth on accounting, which is the operational foundation most offices need to get right first.
How Family Office Software Categories Work Together
Before evaluating individual platforms, it helps to understand how the software landscape is organized. Most family offices, once past a certain level of complexity, operate across several software categories simultaneously.
Accounting and general ledger: This is the financial backbone. It records all transactions, manages entity books, handles intercompany activity, and produces the financial statements that CPAs, advisors, and principals need every day. Platforms in this category include SumIt, Sage Intacct, FundCount, Archway, and more.
Investment and portfolio reporting: This software aggregates holdings across custodians, tracks performance across asset classes, including alternatives, and generates consolidated views of total wealth. Platforms in this category include Addepar, Masttro, Aleta, and Black Diamond. These tools are strong at the investment layer but typically do not replace a proper general ledger.
Bill pay and accounts payable: These tools handle vendor payments, approval workflows, and cash disbursement. BILL is the most widely used tool in this category; it integrates natively with SumIt.
Data aggregation and document management: Tools in this category connect to custodians, banks, and alternative investment managers to pull in statements, capital call notices, and NAV reports. Many investment platforms include this layer, and some accounting platforms are beginning to as well.
Integrated or all-in-one suites: This is where to proceed with caution, as these platforms claim to cover most or all of these functions within a single platform. Eton Solutions, Archway, and FundCount sit in this space, with varying trade-offs between depth and breadth.
Understanding which layer you need to strengthen first is often more useful than asking "which single platform should we use?" Most family offices already have at least one system in place, so the question becomes more about where you have the biggest gaps and what you need to close them.
What to Look For in Family Office Accounting Software
The following capabilities distinguish a strong family office accounting platform from a generic tool:
Unified multi-entity general ledger
The ability to manage all entities — trusts, LLCs, holding companies, operating businesses, personal accounts — within a single platform. This eliminates the tedious practice of maintaining separate books or files per entity, and also makes it easy for various users in the family office to have real-time visibility across the books.
Automated consolidations and intercompany accounting
Family offices with layered ownership structures need more advanced consolidation capabilities. The best platforms automate intercompany journal entries and eliminations, which reduces the hours of manual work that typically come with month-end close.
Ask vendors how they handle multi-level consolidation and whether elimination entries are automated or require manual configuration each period. Further, ask what kind of consolidation they offer, such as equity pick-ups, full consolidation, or partial consolidation.
Ease of use for lean teams
Many single-family offices operate with small teams where the person managing accounting also handles operations, reporting, vendor management, and more. Software that requires a full-time administrator or specialized training creates a bottleneck, as if that person leaves, nobody else is able to use it effectively off the bat. Multi-family offices, similarly, cannot afford to spend weeks on implementation. That’s why the best platforms balance powerful capabilities with intuitiveness — because not all users have a deep accounting background.
Flexible, stakeholder-aware reporting
Similarly, not all stakeholders need the same reports. Principals often want high-level net worth summaries and cash flow snapshots, while analysts, CPAs, and advisors need more detailed reports that get into the nitty-gritty. It’s important to choose software that’s built for both, or at least gives users the option.
Integration with custodians, banks, and partner platforms
Manual data entry from bank statements, custodial reports, and bill-pay platforms is a huge time sink. You should evaluate how each platform connects with your existing ecosystem — particularly banks, custodians, and tools like BILL for accounts payable or Addepar for investment reporting. Native integrations that sync automatically are more valuable than CSV import-export workflows for this reason. Also, note that a platform that tries to do everything in one place can end up being a "houseboat" — neither a good boat nor a good house — which is why integration architecture matters more than feature breadth.
Audit trail and compliance readiness
Family offices operate in a high-trust environment where accuracy and accountability are built into the platform. Look for platforms with robust audit trails, role-based access controls, and SOC 2 compliance. Internal governance and external audits need to see change history, so choose a tool that makes that data readily available as needed.
Proven at Scale: What SumIt Clients Have Achieved
Before diving into individual platform comparisons, it is worth establishing what strong accounting software delivers in real-life use cases. SumIt clients have produced results that illustrate what the right platform makes possible:
Mariner Ultra migrated 150+ entities and now generates consolidated reports across its entire portfolio with a single click.
Ieomia, a private single-family office, replaced more than 65 QuickBooks files to centralize accounting across a complex portfolio.
Point North Capital evaluated QuickBooks Enterprise and Sage Intacct before selecting SumIt for its multi-entity consolidation capabilities and cost-effective implementation.
Overlook Ventures onboarded 19 entities with clarity and speed, reducing time spent on accounts payable and bank reconciliations from day one.
These outcomes are what purpose-built family office accounting software makes possible. They serve as the benchmark against which we evaluate all platforms in this guide.

How We Evaluated These Family Office Platforms
Our evaluation is grounded in conversations with hundreds of family offices over several years, including principals, CFOs, analysts, accountants, operations leaders, and family members. These conversations consistently surface the same pain points: multi-entity complexity, fragmented systems, manual reporting, and lack of transparency.
Each platform was evaluated across five dimensions:
Family office–specific design. We prioritized software built for family office use cases rather than adapted from fund accounting or corporate ERP systems, which is what most FOs are forced to do. Teams lose tens or hundreds of hours a month configuring their systems this way.
Multi-entity accounting and consolidation. We assessed how well each solution handles complex, multi-entity environments — including intercompany activity and entity-level visibility — without heavy customization.
Ease of use and scalability. We evaluated each platform's ability to scale alongside growth in entity count, headcount, and complexity without requiring disruptive overhauls.
Reporting, transparency, and access. We assessed reporting flexibility, accuracy, and ease of use across the full spectrum of family office stakeholders and software users.
Integrations and automations. We examined how each platform reduces manual effort through automation and integrations with popular partner platforms.
Platform Reviews
SumIt — Best Overall for Family Office Accounting
Best for: Single and multi-family offices with multi-entity structures seeking purpose-built accounting with modern usability.
Key strengths: Ease of use; multiple consolidation methods (equity, partial, and full consolidation), native multi-entity GL; automated consolidations; flexible stakeholder reporting; partnership accounting; native BILL and Addepar integrations; a direct MCP connection to AI tools like Claude and ChatGPT.
Limitations: Focused specifically on accounting workflows; not designed for corporate accounting environments
Pricing: Subscription-based; contact for current pricing.
SumIt was built from the ground up for family office accounting, in partnership with family offices, addressing the limitations of generic accounting tools that were never intended to support complex ownership structures and multi-entity consolidations. Rather than adapting a corporate ERP or small business product, SumIt's architecture is shaped around the needs of family offices — from single-family operations to complex multi-family environments. Features like entity hierarchies, ownership visualization, and consolidated reporting are native to the platform rather than bolt-on configurations.
A unified multi-entity general ledger. At the core of SumIt is a modern, powerful general ledger that lets users manage all entities in a single platform. Users can visualize ownership structures and handle inter-entity journal entries with automated eliminations. For context, broad accounting systems like Sage Intacct provide strong multi-entity consolidations but are designed for enterprise finance teams and often require heavy setup to model complex family office structures. Generic platforms frequently leave family offices stitching together separate books, which increases reconciliation work and delays insight.
Reporting built for the full range of stakeholders. SumIt's reporting was built with the full range of family office stakeholders in mind — from high-level net worth snapshots and cash flow summaries for principals to detailed, customizable reports for analysts and external advisors. Users can tailor reporting outputs to suit varying levels of technical comfort and informational depth. This matters in family offices where a single report package may need to serve a principal who wants a one-page overview or an in-house accountant who needs transaction-level detail.
Native integrations with key partners. SumIt integrates with BILL for streamlined payment management and Addepar for investment data reconciliation. It is one of the only family office accounting platforms with a native Addepar integration, so users don’t have to spend time exporting CSVs or entering data manually.
Direct connection to the AI tools family offices use daily. SumIt also announced its MCP server, which connects its ledgers, balances, and journal entries to the AI tools family office teams already use. This means that any SumIt user can ask plain-language questions, such as, "What's the trial balance for the trust as of last quarter?" or "Show me all entries tagged 'Q1 capital call.'" The AI runs the lookup against SumIt and answers in seconds, with a deep link back for user confirmation as needed.
Where SumIt fits less well. SumIt is focused specifically on accounting workflows. Family offices that need a single platform covering banking, bill pay, investment performance tracking, and accounting in one unified suite may want to evaluate broader platforms like Archway or Eton Solutions. SumIt's approach is to do accounting exceptionally well and partner with best-of-breed tools for adjacent functions.
FundCount — Best for Investment-Focused Accounting
Best for: Investment-focused family offices needing GL and partnership accounting combined.
Key strengths: Unified portfolio partnership and GL accounting; multi-currency support; strong investment analytics; auto-reconciliation.
Limitations: Steeper learning curve; interface less modern than newer platforms; less flexible for broader family office workflows.
Pricing: User-based pricing; contact for details.
FundCount combines general ledger, investment, and partnership accounting into a single platform — a distinction that matters for offices with complex investment structures. The platform supports capital call tracking, distribution accounting, NAV calculations, multi-currency operations, and partnership allocations that few accounting-focused competitors match.
FundCount is particularly well-suited for family offices where investment accounting is the primary use case. It has a strong track record with fund administrators and investment-focused offices, and its auto-reconciliation capabilities reduce manual effort at month-end close. The platform also includes AI document intelligence for processing alternative investment statements.
The trade-off is usability. FundCount's interface has a steeper learning curve than newer platforms, and teams that primarily need a strong general ledger with family-office-specific workflows may find other options more approachable. The platform is strongest when investment accounting complexity is the core requirement.
Archway Platform (SEI) — Best for Large, Institutional-Scale Offices
Best for: Large family offices, often with outsourced services from SEI, managing complex structures across multiple jurisdictions.
Key strengths: Enterprise-grade accounting; deep fund and trust capabilities; sophisticated reporting; handles master-feeder and fund-of-funds structures.
Limitations: High cost; less flexibility for leaner offices; typically bundled with outsourced services.
Pricing: Enterprise pricing; contact for details.
Archway provides enterprise-grade accounting and reporting tailored for highly complex environments, often paired with outsourced services from SEI. The platform handles sophisticated ownership structures, including master-feeder, fund-of-funds, and nested entities, and automatically creates the underlying journal entries behind complex back-office operations — investment activity, cash management, and partnership tracking.
For the largest family offices managing billions across dozens of entities and jurisdictions, Archway offers institutional-grade depth that few competitors match. Its reporting capabilities are particularly strong for offices that produce sophisticated, presentation-quality packages for family members and external advisors.
The trade-off is cost and flexibility. Many Archway implementations are bundled with outsourced accounting services from SEI, which provides access to experienced staff but limits direct control over day-to-day operations. Leaner offices, or those that want full ownership of their workflows, may find the platform constraining relative to its cost.
Eton Solutions — Best for MFOs Seeking a Comprehensive Platform
Best for: Multi-family offices and larger single-family offices needing accounting, reporting, document management, and client portals in one overarching platform.
Key strengths: Broad platform depth; client-facing portal; workflow automation; enterprise-grade capabilities.
Limitations: Premium pricing; complex implementation; may be overbuilt for leaner offices.
Pricing: Enterprise pricing; contact for details.
Eton Solutions offers AtlasFive, a comprehensive operating platform covering accounting, investment reporting, document management, client portals, and workflow automation. Its positioning as a full "system of record" for wealth management is well-suited to multi-family offices that serve multiple client families and need capabilities that span well beyond accounting.
Eton's strength is breadth. For offices managing multiple client relationships, the platform's client-facing portal and relationship management capabilities address needs that pure accounting platforms do not. Workflow automation and document management within the same environment reduce the number of disconnected tools an office needs to manage.
The trade-off is complexity and cost. Eton Solutions sits at the enterprise end of the market, with implementation timelines and pricing that reflect the platform's scope. The depth of any individual module — accounting, reporting, document management — may not match best-of-breed alternatives in each category. Leaner single-family offices or offices that primarily need a strong general ledger are likely better off using a more focused platform.
Sage Intacct — Best for Complex Financial Management with In-House Teams
Best for: Family offices with operating businesses and dedicated finance teams requiring deep financial management.
Key strengths: Robust GAAP compliance; strong multi-entity consolidations; sophisticated allocation rules; large partner ecosystem.
Limitations: Not family-office-specific; resource-intensive implementation; family-office-specific features require configuration.
Pricing: Contact for current pricing; typically mid-to-high range.
Sage Intacct offers strong multi-entity accounting, GAAP-compliant reporting, and enterprise-grade automation. It is a solid option for accounting-led teams managing complex structures, particularly those with dedicated accounting resources, experienced finance professionals, and established relationships with Sage implementation partners.
Sage Intacct's depth is as a financial management platform. It supports sophisticated allocation rules, dimensional reporting, and automated revenue recognition, capabilities that matter for family offices with operating businesses or institutional-grade reporting requirements.
Because it was not designed specifically for family offices, customization and implementation can be resource-intensive. Family-office-specific features like ownership structure visualization, family-level reporting, and principal-friendly dashboards are not native to the platform and typically require configuration by an implementation partner. Sage Intacct tends to be most suitable when organizations already have experienced finance teams and are willing to invest in a longer, partner-led implementation process.
NetSuite — Best for Enterprise ERP Requirements
Best for: Larger family offices with ERP needs, particularly those managing operating businesses.
Key strengths: Robust cloud ERP; strong financial controls; scalability; broad ecosystem.
Limitations: High cost; complex implementation; frequently overbuilt for family offices; limited family-office-specific workflows.
Pricing: AUM/module-based; among the priciest options evaluated.
NetSuite is a cloud-based ERP platform with strong financial controls, scalability, and a wide ecosystem of modules and integrations. It is a reasonable choice for family offices that need a full ERP across multiple business functions — particularly those that also manage operating businesses alongside their investment portfolio.
NetSuite is one of the priciest options available and frequently requires significant implementation effort and ongoing administrative overhead. Family-office-specific workflows are limited, and many offices find they are paying for modules and capabilities they do not use. It fits best when the family office operates more like a mid-market enterprise than a lean private office.
QuickBooks — Best for Small, Simple Accounting Environments
Best for: Smaller family offices beginning their digital journey, with limited entities and basic accounting needs.
Key strengths: Familiar interface; widely accessible; lower cost; large accountant network.
Limitations: Requires separate files per entity; lacks multi-entity consolidation; QuickBooks Desktop is being discontinued.
Pricing: Subscription starting under $5,000/year; QuickBooks Desktop is being phased out.
QuickBooks is one of the most familiar accounting tools available, providing straightforward bookkeeping and basic reporting. For smaller family offices beginning their digital journey or those with limited accounting complexity and few entities, it remains a reasonable starting point.
For family offices with more complex needs, QuickBooks requires maintaining separate company files per entity and significant manual reconciliation. As entities multiply, this approach becomes increasingly fragile. Intuit has also announced the discontinuation of QuickBooks Desktop, pushing users toward QuickBooks Online, which has historically been less capable for complex scenarios.
Our own customer base includes numerous offices that migrated from QuickBooks after reaching a tipping point where maintaining separate files and manual workarounds became untenable. See the "Signs You've Outgrown Your Current Software" section below for a checklist of when to evaluate alternatives.
Xero — Best for Simple, Early-Stage Accounting
Best for: Very small or early-stage family offices with straightforward bookkeeping needs.
Key strengths: User-friendly; cloud-native; strong bank feeds; affordable.
Limitations: Limited multi-entity consolidation; no native cross-organization reporting; organizations will outgrow it by design.
Pricing: Affordable subscription; typically well under $5,000/year.
Xero is a cloud-native accounting platform marketed toward small businesses. For very small family offices with limited entities and straightforward bookkeeping needs, it can be a reasonable starting point. Each entity requires a separate Xero organization, with no native way to consolidate across them.
Microsoft Dynamics GP — For Legacy Microsoft Environments (End-of-Life 2029)
Best for: Family offices already embedded in the Microsoft ecosystem; migration planning is essential.
Key strengths: Familiar Microsoft environment; solid core accounting.
Limitations: End-of-life December 31, 2029; no further security patches or support after that date; legacy architecture.
Pricing: Contact Microsoft or a reseller; on-premises and hosted options.
Microsoft Dynamics GP provides solid core financial functionality for teams already in the Microsoft ecosystem. Microsoft has announced it will cease all support on December 31, 2029. Family offices on this platform should begin evaluating migration paths now rather than waiting for the support deadline. Many are using the transition as an opportunity to move to a purpose-built family office platform rather than migrating to another general-purpose ERP.
SoftLedger — Best for API-First Teams with Simpler Multi-Entity Needs
Best for: Technology-forward teams that value developer-friendly architecture and fast implementation.
Key strengths: Modern cloud-native architecture; strong API; fast implementation (~45 days); real-time consolidation.
Limitations: Not family-office-specific; smaller ecosystem of FO-specific integrations; less depth for complex ownership structures.
Pricing: Contact for current pricing.
SoftLedger is a modern, cloud-native accounting platform with a strong API and a fast implementation timeline. It handles multi-entity consolidation, intercompany eliminations, and real-time reporting well, making it a good fit for technology-forward teams. It was not designed specifically for family offices, however, and may require additional configuration for complex ownership structures and family-office-specific reporting. Family offices with straightforward multi-entity setups and strong technical teams will get the most from this platform.
Addepar — For Investment Portfolio Analytics
Best for: Investment-heavy family offices requiring deep portfolio analytics and performance reporting across liquid and alternative assets.
Key strengths: Industry-leading investment analytics; multi-custodian aggregation; scenario modeling; trusted at institutional scale.
Limitations: Not an accounting platform; AUM-based pricing that can be significant; designed for investment reporting, not GL or operational accounting.
Pricing: AUM-based; among the higher-priced investment platforms.
Addepar is the most widely used investment analytics platform among family offices and RIAs. It aggregates data from custodians and private sources, provides portfolio performance measurement, and produces reporting across both liquid and alternative investments. It is the category standard for investment-side analysis.
Addepar is not an accounting platform and should not be evaluated as one. Offices that use Addepar for investment reporting will still need a separate general ledger. SumIt's native Addepar integration is designed specifically for this, and a large percentage of SumIt customers take advantage of the feature.
Masttro — For Consolidated Wealth Visualization
Best for: Single and multi-family offices needing a comprehensive view of total wealth across all asset classes, with strong alternative asset support.
Key strengths: Comprehensive wealth aggregation including alternatives; 650+ direct custodian feeds; AI-powered document processing; strong mobile experience.
Limitations: Not an accounting platform; investment-reporting focused; pricing is not AUM-based but is enterprise-level.
Pricing: Fixed pricing, not AUM-based; contact for details.
Masttro is a wealth management platform built to aggregate and visualize holdings across all asset classes within a single consolidated view. The platform has deep roots in the needs of complex wealth structures. But, like Addepar, Masttro is a wealth management and reporting platform, not an accounting system. Offices using Masttro for consolidated wealth reporting will typically pair it with a dedicated accounting platform for GL, financial statements, and operational accounting.
Asseta AI — Best for Breadth Over Depth
Best for: Offices building a stack from scratch that want to consolidate vendors — accounting, banking, bill pay, and investment data in one login — and haven't yet hit the accounting complexity where a breadth-first design shows its seams.
Key strengths: Wide operational coverage across GL, banking, bill pay, AP, and investment data; broad integration ecosystem; AI-assisted categorization and reconciliation; SOC 2 Type II.
Limitations: Architected as a suite, with accounting as one module among many rather than the core; by its own comparison, no mobile app, "limited" trust and partnership accounting, and custodian data via integrations rather than direct feeds; founded in 2023 (rebranded from Prismatic in 2025), so its track record at scale for complex family office accounting is still short.
Pricing: Flat-fee tiers based on complexity; no AUM-based fees. Contact for details.
Asseta by its own description, does banking, bill pay, general ledger, investments, reporting, and document management in one environment. For an office whose goal is fewer logins, that breadth is the appeal; however the general ledger is one module among roughly 10 in Asseta’s suite. It is not a platform built around accounting depth, so, for an office where the GL is the system of record, that distinction is important. Asseta lists trust and partnership accounting as "limited.”
As a venture-backed company founded in 2023, Asseta AI is earlier in its development than most platforms evaluated in this guide. Family offices evaluating software for long-term operational infrastructure will note the absence of published client case studies documenting outcomes at scale, which longer-tenured platforms tend to have. For organizations where platform stability and proven longevity are selection criteria, that is a meaningful consideration.
Asseta's strongest fit is a greenfield office assembling its operational stack and prioritizing one vendor over best-in-class depth in any single layer. For offices with existing infrastructure or more complex ownership structures, the trade-offs tend to favor a focused platform instead.
Signs You've Outgrown Your Current Accounting Software
One of the most common questions we hear from family offices is “How do we know when it's time to switch?" The following are the clearest signals that your current accounting software is no longer serving your needs.
You're maintaining separate files or books per entity. If every trust and LLC requires its own QuickBooks file or Xero organization (and consolidation involves exporting data to Excel and manually combining it), you have outgrown your current system. This is the single most common pain point we hear, and it compounds with every new entity.
Month-end close takes weeks instead of days. Family offices on well-suited platforms typically close their books in days, not weeks. If your close process is a regular headache and requires a lot of manual reconciling, the software is the bottleneck.
Reporting requires significant manual effort. If producing a consolidated net worth statement or a report package for an advisor requires hours of Excel manipulation, your platform is not meeting your reporting needs. Modern platforms generate these outputs directly from the system, often in seconds.
Workarounds have become the norm. When custom Excel templates and patchwork are required to compensate for missing features, it’s time to upgrade your software.
New entities create disproportionate work. Adding a trust, partnership, or holding company should be a configuration task. If onboarding a new entity means rebuilding report templates and rethinking your consolidation process, your platform was not designed for multi-entity complexity.
Your team is growing, but your tools are not keeping up. As headcount increases, the need for role-based access, audit trails, and collaborative workflows increases. If your current system lacks user permissions and change tracking, it is time to evaluate purpose-built alternatives.
Your vendor has announced end-of-life. This applies directly to family offices on Microsoft Dynamics GP (end-of-life December 2029) and QuickBooks Desktop (being phased out by Intuit). This is the time to invest in a new platform.
If three or more of these resonate, it is likely time to evaluate a platform designed for the complexity you are managing today — and the complexity you will be managing in two to three years.
Frequently Asked Questions
What is the best family office accounting software?
The best family office accounting software is designed specifically to handle complex ownership structures, multi-entity accounting, and the diverse reporting needs of family office stakeholders. Based on our evaluation, SumIt stands out as the strongest overall option for 2026 because of its native family-office architecture and unified multi-entity general ledger. It’s intuitive and flexible, and is built for family offices directly.
For offices that also want banking and bill pay integrated with their accounting layer, Asseta AI is worth evaluating. Sage Intacct remains strong for teams with deep accounting resources, and platforms like Archway and Eton Solutions serve the enterprise end of the market.
What is the difference between family office accounting software and family office software?
Family office accounting software handles the general ledger, financial statements, entity books, intercompany accounting, and operational reporting — the financial record-keeping layer. Family office software is a broader term that often includes investment and portfolio reporting, wealth aggregation across custodians, document management, and client communication tools. Many offices use both categories, connected through integrations.
Can QuickBooks be used for a family office?
QuickBooks can work for smaller or simpler family offices with limited entities and basic accounting needs. However, it lacks native support for multi-entity consolidation, complex ownership structures, and family-office-specific reporting. Family offices managing more than a handful of entities typically find that QuickBooks requires separate company files and significant manual reconciliation. Intuit's decision to discontinue QuickBooks Desktop may also prompt earlier transitions for offices relying on that version.
What features should family office accounting software include?
Family office accounting software should include a unified multi-entity general ledger, automated consolidations and intercompany eliminations, flexible reporting for different stakeholder needs, strong auditability, and integrations with banks, custodians, and investment platforms. Audit trail capabilities, role-based access controls, and SOC 2 compliance are increasingly important, especially as security and financial integrity heighten. The software should support both high-level reporting for principals and detailed analysis for accountants and advisors.
How much does family office accounting software cost?
Pricing varies widely. Purpose-built platforms typically range from $10,000 to $50,000 per year on subscription-based pricing that scales with complexity. Enterprise solutions like NetSuite, Archway, or Eton Solutions can exceed $100,000 annually when implementation and ongoing administration are included. Simpler options like QuickBooks or Xero start under $5,000 per year, but often require supplemental tools as complexity grows.
Is SumIt built specifically for family offices?
Yes. SumIt was designed from the ground up for single- and multi-family offices, rather than adapted from fund accounting or corporate ERP systems. The platform was built to support the unique operational needs of family offices at every stage of growth.
When should a family office switch from QuickBooks to a dedicated platform?
The most common trigger is when the number of entities or structural complexity makes maintaining separate QuickBooks files untenable. Additional signals include month-end close taking weeks rather than days, difficulty producing consolidated reports, and the need for multi-user collaboration with role-based access.
What is the difference between a purpose-built accounting platform and an all-in-one suite?
Purpose-built family office accounting platforms like SumIt focus specifically on delivering best-in-class accounting capabilities, including a strong general ledger, multi-entity consolidation, partnership accounting, flexible reporting, and strategic integrations with partner tools. All-in-one suites attempt to cover accounting, banking, bill pay, investment tracking, and other functions within a single platform, but don’t specialize in any particular one.
The trade-off is depth versus breadth: purpose-built platforms tend to offer deeper accounting functionality and more refined workflows, while all-in-one suites offer fewer vendor relationships to manage. The right choice depends on whether your office prioritizes accounting depth or platform consolidation.
Is family office accounting software scalable as offices grow?
The best family office accounting platforms are designed to scale as offices add entities, investments, family members, and internal teams. SumIt supports growth from lean single-family offices to complex multi-family structures with dozens of entities, without requiring a disruptive system overhaul. When evaluating scalability, ask vendors how pricing changes as you add entities and whether consolidation performance degrades as entity count increases.
Final Verdict
After evaluating the leading platforms across the criteria that matter most to family offices, SumIt stands out as the strongest overall accounting solution for 2026. Its architecture is native to family office workflows and saves clients hundreds of hours of manual work per month across users.
The outcomes documented across SumIt's customer base, such as 150-entity portfolios consolidated in a single click or 65 QuickBooks files replaced, are the practical measure of what the right platform delivers.
Other platforms have genuine strengths in specific areas. FundCount stands out for investment-heavy operations. Archway and Eton Solutions serve the needs of the largest, most complex institutional-scale offices. Addepar and Masttro are the leading tools for the investment reporting and wealth aggregation layer. And for smaller offices just getting started, QuickBooks remains a familiar entry point — though most offices with growing complexity will eventually migrate to a more capable platform.
The most important consideration is not which platform does the most, but which platform does the most important thing — accounting — exceptionally well, and how cleanly it connects to the rest of your stack.
