How to replace your fund administrator with software

Before you start

Your administration invoice arrived, or a quote did, and the number surprised you. That is the right moment to read this: before the first close, when the delivery model is still a choice, not after you have run two quarters with a provider and are weighing a mid-fund change.

Self-operating fund accounting software means your team closes the books, runs the capital account allocations, and produces the LP statements. The software automates the arithmetic. You are responsible for the output. The cost difference is real where it can be measured. Fundwave's Growth tier costs $12,000 a year on annual billing for a fund up to $250M AUM, as published October 21, 2026. Bundled administration at the same size is quote-based across every provider in the segment; no rate card exists to compare against. FundCount's Incubator starts at $14,450 a year.

Two obligations do not change when you take the accounting in-house: the custody rule audit and K-1 preparation. Both require an external professional with a licence or a mandate you cannot hold yourself. The rest of this guide covers where the line is, how the migration works, and what the audit still demands.

When it works

A software-only model fits a fund that meets four conditions.

US structure, straightforward LP base. A Delaware LP fund with US accredited investors has one set of books, one tax return, and no foreign tax form requirements. Offshore LPs, a parallel fund, a Cayman feeder, or a fund-of-funds structure each add accounting complexity that no software discount recovers.

Under $100M AUM and fewer than 100 LPs. Fundwave's Seed tier covers up to $50M AUM per fund and 100 investors; the Growth tier covers up to $250M and 250 investors. The $100M threshold also matters institutionally. Large LP investors, including endowments and pension funds, frequently require an independent administrator named in the GP's Form ADV as a condition of investment. Software cannot satisfy that requirement.

Internal accounting capacity. Someone on your team, or a part-time controller, must operate the system, close the books each quarter, and be available when the auditor requests working papers. At a $25M fund with two capital calls a year, that is a few days a quarter. At $100M with side letter variations and a carried interest waterfall, it is closer to a part-time role.

Starting at formation, not mid-fund. The cleanest time to adopt software is at fund formation, before the first close. Moving mid-fund requires transferring the full general ledger history, reconciling capital accounts per LP back to inception, and rebuilding every calculation. That is the same work as switching between two human administrators, with the same timeline.

Prices read October 21, 2026. Onboarding fees are separate: $2,000 for Fundwave Seed, $3,500 for Growth. FundCount charges a digital transformation and hosting fee not published on its pricing page. Allvue is a fourth option for larger funds, but prices are quote-based.

The handover package

When you leave a traditional administrator, everything you need is in their system. Getting it out is the migration. Incomplete data is the most common reason a move drags past its planned timeline.

Request all of the following, by name, in machine-readable form:

• General ledger and trial balance at cutover, and the full transaction history from inception.
• Capital account statements per LP, every quarter from inception.
• Investment cost basis, valuation history, and the valuation support documentation.
• Fee calculations for the management fee and carry, with the waterfall logic as applied.
• Investor records: contacts, commitments, subscription agreements, side letters, and the KYC and AML files if the administration agreement permits transfer.
• Every capital call and distribution notice, quarterly report, K-1, and audit report.

Ocorian warns that an outgoing administrator may try to hand over only the closing balances and let the incoming party start from there. Insist on the full transaction history. Without it, every LP or auditor question about a pre-migration figure goes to a firm you no longer pay.

The audit

The SEC custody rule (Rule 206(4)-2) requires an investment adviser who has custody of fund assets to deliver audited financial statements to all LPs within 120 days of the fund's fiscal year end. For a fund of funds, the SEC staff has stated the window extends to 180 days. The auditor must be independent of the fund and registered with the PCAOB.

None of that changes when you self-operate with software. The requirement is about who audits, not who prepares the books. When a traditional administrator runs the ledger, the auditor reviews the administrator's trial balance and working papers. When you self-operate, the auditor reviews yours. Both paths produce the same deliverable: audited financial statements issued within the custody rule window.

What does change: you are now the person the auditor contacts when something in the working papers does not reconcile.

What still needs a person

Tax preparation. Fund accounting software generates the data that feeds a partnership tax return. It does not prepare Form 1065 or each LP's Schedule K-1. AngelList's Institutional plan, which includes full fund administration, lists K-1 preparation as a paid add-on not in the base price. Fundwave and FundCount produce no tax deliverable at any tier. Budget a tax engagement as a separate line when you strip it from an administration contract.

The annual audit. The custody rule requires the auditor to be independent of the fund. An independent auditor is, by definition, external. Self-operated software does not satisfy that requirement.

Exception handling. When a capital call wire arrives short, when an LP disputes a capital account balance, or when a transaction will not categorize cleanly, someone must decide. Software surfaces the discrepancy; it does not resolve it.

LP transfers, side letter amendments, and secondary approvals. Each requires execution by the GP entity. Software can route and track documents; it cannot sign them.

Regulatory filings requiring legal judgement. Form ADV preparation, state blue sky notices, and FBAR filings require an interpretation of whether the filing is required and what it says. Software can set a reminder; it cannot opine.

When it stops working

The case for software weakens as the fund grows. A co-investment vehicle, a parallel fund, or a Cayman feeder adds accounting work that the software handles but the quarterly close time compounds. An SEC registration at over $150M in regulatory assets under management adds a compliance layer that fund accounting tools do not address.

The signal is the quarterly close. If it expands past four days, or the auditor's prepared-by-client list reaches 60 line items, the controller's time is beginning to cost more than a bundled administrator would. At that point the guide to reducing administration costs and a fresh set of quotes belong on the same desk. If you decide to move to a full administrator, the guide to switching covers the handover in detail.
