Family Office Technology Selection: One Source of Truth
The debate over single family office technology selection typically collapses into a feature comparison: all-in-one platform versus best-in-class ecosystem, fewer vendors versus greater functionality, or simplicity versus specialization.
Asya Nagdimova has a more operational view. A senior executive at a large New York single family office with more than fifty professionals, she has implemented multiple systems across three different offices. In a recent episode of The Family Office Project, she and Jon discuss her experiences and she reframes the technology choice directly, "You don't really choose 'one tool.' You choose your primary system of record — and then you build around it."
A family office system of record is the primary platform that holds the history, entity structure, ownership tracking, and institutional memory, the foundation everything is built around. Using that framework changes the question asked during a technology search and selection. The relevant decision is not which platform wins on features, it is which platform can hold the office's history, structure, and institutional memory as its primary source of truth.
Single Family Office Technology Implementation: Where It Gets Hard
Nagdimova's current office runs on SEI Archway as its primary system — general ledger, partnership and entity accounting, accounts payable, ownership tracking, allocations, document attachment, and reporting for tax and other stakeholders. She describes the move from consumer tools plainly: "From Quicken to Archway — it's like a Rolls-Royce for our family office."
When Nagdimova joined her current office, the implementation was already underway — but the system design did not reflect what the investment team actually needed. The platform had been configured on a tax-basis logic. The investment director could not use what it produced. Correcting that required rebuilding assumptions across six hundred investments, three hundred entities, and five hundred bank accounts, with history dating to inception.
All-in-one systems force alignment. If internal stakeholders disagree on reporting logic, ownership structure, or account architecture, the platform surfaces that disagreement immediately. That is not a defect but the structural cost of running a complex office on a shared foundation — and one that most offices encounter later than they expect.
Why Continuity Is the Strongest Argument for a Single System of Record
The stronger argument for a single primary system has less to do with efficiency and more to do with risk.
Family offices operate on long time horizons but their institutional memory does not. A common concern is that people stay for decades, then they retire, or leave. The knowledge they carry does not transfer automatically, and in many offices, it does not transfer at all.
Nagdimova is direct on this point, "The most important factor is continuity. If tomorrow somebody leaves, that information is there and nobody can take this with them."
A single system of record reduces key person dependency in a specific way. It removes the office's exposure to any one accountant's macro logic, any one executive assistant's undocumented process, or any one analyst's workbook structure. The platform holds the institutional memory whereas the people and team provide the judgment.
Where a Single Family Office System Falls Short
Nagdimova's office does not run on Archway alone.
The investment team required depth that Archway does not fully provide — benchmarking, analytics, and investment-specific reporting. So they added Addepar, then they added Orca for entity and document history, and finally they added Arch for document ingestion. Each specialist tool addresses a gap in the primary system.
This is not a contradiction of the single-system argument. It is a clarification of it. All-in-one does not mean only one tool, it means one backbone. Archway remains the source of truth and everything else is in support of that.
The alternative — a fragmented stack without a clear primary system — tends toward a different failure. Specialist tools generate workarounds. Teams build macros and custom processes to bridge gaps between platforms. When knowledge concentrates in those workarounds, the office becomes dependent on the same individuals it was trying to protect itself from losing.
A Practical Sequence for SFO Technology Selection
For offices still running on spreadsheets or entry-level accounting software, Nagdimova's position is clear, “Bring the system. The system is the 21st century. You cannot survive without the system."
Her practical sequence:
Start with the foundation — general ledger, bill pay, allocations, entity accounting.
Build capability over time rather than attempting full configuration in the first phase.
Retain advisors who understand what the office actually needs, not only what the software can do.
Choose systems that preserve institutional history and reduce dependency on individual staff.
The Governance Problem Behind Family Office Technology Decisions
Technology conversations in family offices tend to focus on platform capabilities. Nagdimova's experience points elsewhere. Systems do not fail because they lack features. They fail when the office lacks internal alignment — on reporting logic, on ownership structure, on what the system is meant to produce and for whom.
The technology selection question is, at base, a governance question. It requires the office to reach agreement on what it tracks, how it tracks it, and who needs access to it. The platform enforces those agreements. It does not create them.
