Summary
Challenge: P Holdings was running on a custom-built internal accounting system entirely dependent on one employee and with no cloud access — a key-man risk the family office could no longer accept. At the same time, a new tax loss harvesting strategy was generating over 1,800 transactions a month from a single brokerage account alone, a complexity that a traditional general ledger couldn't support.
Solution: P Holdings implemented SumIt, consolidating its accounting into a single investment-aware general ledger with native Addepar integration and real-time cash connectivity.
Result: SumIt gave P Holdings a scalable, reliable accounting foundation — and seamless support for a sophisticated new investment strategy that simply wouldn't have been possible in a traditional GL.
Customer Overview
P Holdings is a single-family office managing a portfolio that spans two distinct asset classes: mineral rights and non-operating working interests on the oil and gas side, alongside a sophisticated capital markets portfolio that includes private and public investments.
The accounting at P Holdings is complex in some ways (many entities, very different asset classes) and very simple in others (no business operations, just financial products, oil and gas royalties, and non-operated interests). The two sides of the business require fundamentally different accounting treatment, and the system holding it all together needed to handle both without compromise.
Challenges
For years, P Holdings ran on a bespoke accounting system built by an internal accountant. While it served its purpose, the arrangement carried a fundamental vulnerability: the entire system's institutional knowledge lived with one person. If that employee ever left, so would the continuity, the support, and the know-how to keep it running.
That risk was reason enough to move. P Holdings needed a platform that the whole team could rely on independently, without requiring a specific individual to operate or maintain it. Most importantly, it would need to remain stable regardless of team changes.
At the same time, the capital markets portfolio was adding a new layer of complexity. P Holdings had begun deploying a quantitatively managed tax loss harvesting strategy — a sophisticated approach that, by design, generates an exceptionally high volume of transactions. A single brokerage account alone produces over 1,800 transactions per month, documented across 500-page statements from Fidelity.
Accounting for this investment properly involved significant processing volume and a system that could connect directly to the investment data and handle the treatment correctly. Both of those things are often too much for a traditional general ledger to handle.
The two problems arrived together: a system that couldn't scale without key-man risk, and a new investment strategy that demanded more than a traditional GL could offer.
Evaluation Process
P Holdings evaluated a variety of accounting systems, including oil and gas-specific systems such as OGSYS and Wolfpack, as well as small business systems such as Sage and family office systems such as Fund Count and Asset Vantage. After speaking with a wide variety of options, the team narrowed down to 2: Asset Vantage and Sumit. Asset Vantage featured a platform with a broader feature set and more corporate-level controls. On paper, Asset Vantage looked comprehensive. In practice, it felt like the wrong fit.
"The other system felt bulkier. You all just had the ease of use and the cash tie. I don't think they had the live feed from cash accounts, and that was number one for me."
The live connection between SumIt and P Holdings's cash accounts was the deciding factor. For a CFO who needs to know that the accounting system is never out of step with actual cash, that was the bar that everything else was measured against.
Solution
The clearest proof point of SumIt's fit for P Holdings is what the Addepar integration makes possible for the AQR strategy.
Tax loss harvesting at this level of sophistication generates real accounting complexity. A single brokerage account produces over 1,800 transactions per month that need to be reconciled, with realized and unrealized gains and losses accounted for correctly — and that's before accounting for the rest of the portfolio. Doing this manually against 500-page Fidelity statements is, at nothing more, a feasibility problem.
A traditional general ledger can't solve it. SumIt's Addepar integration, however, can. It can pull investment data directly into the general ledger and enable the accounting treatment the strategy requires.
"It wouldn't be possible with a non-automatized GL. The Addepar integration with Sumit is what makes it work."
As far as what’s working, P Holdings sums it up into four main categories:
A system that the team owns in the cloud. Moving off a custom-built solution means P Holdings's accounting no longer carries key-man risk and is accessible from anywhere (with appropriate security in place). The platform is reliable, supportable, and accessible to the whole team, regardless of who's in the seat and where they sit.
Real-time cash connectivity. The live tie to cash accounts means P Holdings's books are never out of step with what's actually in the bank. Drilling into a balance that doesn't look right and tracing it back to the source is fast and intuitive.
Addepar integration for complex investment activity. Over 1,800 monthly transactions from a single AQR brokerage account flow through without manual entry, with the accounting treatment that a traditional GL would require significant manual work to approximate, and with the full portfolio volume handled on top of that.
A single system for two very different asset classes. Oil and gas operations and a capital markets portfolio sit in the same general ledger, with the flexibility to handle each appropriately.
Looking Toward the Future
The team is looking forward to further enhancements to the Addepar integration to bring in even more data and is also excited about additional workflows to help streamline the month-end close.
Why Investment-Aware Accounting Matters for Family Offices
For single-family offices managing sophisticated investment strategies, P Holdings's experience illustrates an important point: the choice of general ledger software comes down to whether the software is truly investment-aware. For P Holdings, that meant a platform the team could rely on without key-man dependency, and an Addepar integration capable of supporting a new investment strategy that a traditional GL simply couldn't handle — starting with over 1,800 transactions a month from a single brokerage account alone.
