Family office accounting software, compared

Seven platforms family offices commonly evaluate for consolidated accounting and reporting. Public information only. Methodology pinned at top.

Methodology

Evaluated May 9, 2026 · Updated May 9, 2026

Vendors were selected from the top organic SERP for "family office accounting software" and adjacent queries — Forbes 2025 roundup, vendor pages ranking on page 1, and active discussion threads. Ratings reflect public information only: vendor websites, vendor public collateral, public press, and industry commentary referenced inline. We do not rate based on private demos, private references, or undisclosed pricing.

Every vendor in the matrix carries at least two non-"Strong" ratings — this is a deliberate fairness rule. No vendor gets a clean sweep, because no vendor in this category actually has one.

Family Office Advisory has no commercial relationship with any of the listed vendors. No vendor reviewed the matrix prior to publication. Ratings will be revisited on the date in the page header at minimum every 12 months.

Situational guidance

If you're choosing today

There is no winner across all criteria. Pick by your weakest 1–2 capability gaps. If your bottleneck is investment-data aggregation, the choice narrows to Masttro, Addepar, Archway, or Altoo. If consolidation across many entities is the pain, all seven clear the bar, but Sage Intacct, Archway, and Altoo have the most polished entity models. If a clean, modern UX for principals and family members matters most, Altoo and Masttro lead the set. If AI-driven document handling matters, Asseta AI is the only AI-native entrant in this set.

Implementation pain is the underrated risk

Cost is rarely the problem; implementation drag is. Plan for months, not weeks, on the higher-end platforms. SumIt is the outlier on speed at the lower-AUM end; Altoo positions a structured onboarding that lands between SumIt and the heavier enterprise stacks.

Pricing transparency is uniformly poor

Six of the seven don't publish ranges. SumIt and (to a lesser extent) Sage are the most willing to discuss numbers without an MSA. Treat opacity as a negotiating signal, not just an inconvenience.

European data residency

If European data residency or Swiss-domiciled processing matters for your structure, Altoo is the only Swiss-headquartered entrant in this set. The others can typically meet EU or Swiss data-handling requirements contractually, but Altoo's domicile is itself a positioning point.
