FundCount is a strong fit when you want a unified multi-currency general ledger plus partnership and portfolio accounting with reporting and an investor portal.

SS&C Advent Geneva is often evaluated when the requirement is multi-asset institutional accounting, investor servicing, and scalability.

FAQ

What is family office accounting software?

Family office accounting software is a system used to maintain books and records across multiple entities (trusts, partnerships, holding companies), account for investments across asset types, reconcile data sources, and produce repeatable reporting packs. In practice, it sits between “general ledger accounting” and “investment accounting,” with strong controls and reporting requirements.

Can family office accounting software handle private equity and real estate?

Some platforms explicitly position support for private assets and alternatives, while others require more customization or complementary processes. For example, FundCount positions portfolio accounting for private equity, real estate, derivatives, and debt. SS&C Advent’s family office Geneva brief also discusses supporting diversified family office assets, including private equity, real estate, and hard assets.

Do I need both portfolio accounting and a general ledger?

Often, yes. Portfolio accounting tracks holdings, transactions, valuations, and performance. The general ledger supports trial balance, financial statements, and governance controls. SS&C Advent’s family office brief calls out the need for a built-in investment and partnership general ledger to generate a trial balance.

What is “ABOR” and why does it matter?

ABOR stands for accounting book of record. It refers to maintaining a complete set of books and records from which accounting outputs are produced. Enfusion’s materials describe a double-entry general ledger that maintains a complete set of books and records (ABOR).

How long does implementation take?

It depends on the number of entities, the complexity of your assets, and the amount of historical data you migrate. Platform-oriented implementations typically require more governance and reconciliation work. The practical way to reduce risk is to plan a parallel close and reconcile outputs against your current process before switching fully.

What questions should I ask in a demo?

Ask about entity modeling, multi-currency, how private assets are booked, reconciliation workflows, period locks, audit trail, reporting packs, and how data integrates with custodians and other systems. The “demo questions” lists above are designed to be copy-pasted into vendor meetings.

Can these systems replace our reporting platform?

Sometimes. Some tools include strong built-in reporting and portal delivery. FundCount, for example, positions reporting templates and the ability to distribute statements securely, plus an investor portal. Other platforms may require a BI layer or separate report production depending on your needs.

What controls should we expect (audit trail, approvals, locked periods)?

At minimum: user entitlements, audit logs, the ability to lock periods, and a controlled reporting distribution process. Geneva emphasizes accounting integrity across open and closed periods.
FundCount describes distribution workflows with approvals and encryption in its reporting context.
