Outsourced Bookkeeping for Nonprofits: A Buyer Guide

Outsourced bookkeeping for nonprofits is the practice of hiring an outside firm to maintain your organization’s books — recording gifts and grants, tracking restricted funds, reconciling accounts, and preparing the records your Form 990 and any audit will draw from. It is a well-established option: nothing in the tax code requires a nonprofit to keep bookkeeping in-house, and Form 990 openly asks whether an independent accountant touched your financial statements.

This page is written for finance leads and executive directors weighing a provider — the buyer’s angle. If you want the step-by-step mechanics of how to keep nonprofit books, start with our nonprofit bookkeeping guide. Here we focus on why organizations outsource, what to look for, and how the engagement works.

Can Nonprofits Outsource Bookkeeping?

Yes — there is no IRS prohibition on a nonprofit using an outside accountant, and the annual return assumes many do. Form 990 asks the organization to disclose whether its financial statements were compiled, reviewed, or audited by an independent (outside) accountant. That disclosure line implicitly recognizes outsourced financial-statement work as normal and expected.

“Were the organization’s financial statements compiled or reviewed by an independent accountant?” — Internal Revenue Service, Form 990, Part XII, Line 2a

The scale of the sector shows how routine professional support has become. Roughly 1.54 million 501(c)(3) charitable organizations existed in 2024, out of nearly 1.9 million organizations exempt under all of Section 501(c), and the IRS processed 136,323 exempt-status applications that year (IRS Data Book 2024). Most of those organizations rely on outside accounting help of some kind.

What Does a Nonprofit Bookkeeper Do?

A nonprofit bookkeeper records and organizes the transactions behind your financial statements and Form 990 — but with rules a commercial bookkeeper rarely handles. The work centers on fund accounting, grant and program tracking, and the donor-facing paperwork the IRS requires.

Core responsibilities usually include:

• Fund accounting — separating restricted from unrestricted money so each gift is spent as promised.
• Grant and program tracking — tying expenses to the grant or program that funded them, ready for funder reports.
• Donor acknowledgments — issuing the contemporaneous written acknowledgment the IRS requires for any single gift of $250 or more, and the disclosure statement for quid pro quo payments over $75.
• Form 990 readiness — maintaining the gross-receipts, asset, and public-support figures that decide which return you file.
• Audit prep — keeping GAAP-based books an outside CPA can rely on.

What Is Fund Accounting for Nonprofits?

Fund accounting is the method nonprofits use to track money by donor restriction rather than as one pooled balance. Under U.S. GAAP, a nonprofit reports net assets in donor-restriction classes, so restricted grants are never quietly spent on general operations.

The current standard, FASB Accounting Standards Update No. 2016-14, requires two net-asset classes (net assets without donor restrictions and net assets with donor restrictions), replacing the older three-class model. Getting this classification right is the single biggest reason a nonprofit needs a bookkeeper who knows the sector. Our primer on restricted grants covers the day-to-day tracking in more depth.

Is Outsourcing or In-House Bookkeeping Better for Nonprofits?

Neither is universally better — it depends on your budget, complexity, and how much continuity you need. The table below compares the two on the factors nonprofit finance leads weigh most, using verifiable labor benchmarks where they apply.

How Much Does Outsourced Bookkeeping for Nonprofits Cost?

Pricing is scoped to your organization’s size and reporting burden, so it varies by organization, but the labor benchmark anchors the comparison. An in-house clerk runs a median $49,210 a year before benefits (BLS, May 2024), and outsourced fees are typically set against that same workload.

The biggest cost driver is which Form 990 you file, because each return demands a different level of bookkeeping detail:

• Form 990-N (e-Postcard) — gross receipts normally $50,000 or less; minimal bookkeeping.
• Form 990-EZ — gross receipts under $200,000 and total assets under $500,000; more detail.
• Full Form 990 — gross receipts of $200,000 or more, or total assets of $500,000 or more; functional-expense allocation and full schedules.

If you receive federal funding, note that a “reasonably proportionate share” of a required Single Audit is an allowable charge against federal awards (2 CFR 200.425), so part of your outsourced financial function can be funded from the grant. You can see how we scope engagements on our outsourced accounting and bookkeeping services page.

When Should a Nonprofit Outsource Its Bookkeeping?

Consider outsourcing when your reporting burden outgrows your in-house capacity — usually at a growth, funding, or compliance threshold. The clearest triggers are dollar figures set by the IRS, federal regulators, and your state.

• You cross a Form 990 tier — moving from the e-Postcard to Form 990-EZ or the full 990 sharply raises the accounting detail required.
• You take federal awards — expending $1,000,000 or more in federal awards in a fiscal year triggers a required Single Audit (2 CFR 200.501), which presupposes clean, GAAP-based books. That threshold rose from $750,000 effective for fiscal years beginning on or after October 1, 2024.
• Your state mandates an audit — California requires an independent CPA audit at $2,000,000 in gross revenue under the Nonprofit Integrity Act, and New York sets a lower bar of $1,000,000 (with a CPA review between $250,000 and $1,000,000).

How Do I Choose an Outsourced Bookkeeping Provider for My Nonprofit?

Choose a provider by fund-accounting experience, audit readiness, and fit with your size — not price alone. The right partner keeps books an outside auditor can rely on and flags compliance issues before they become filings problems.

Questions worth asking any candidate:

1. Do you keep books under the two-class net-asset model required by FASB ASU 2016-14, and can you show grant-level tracking?
2. Have you prepared organizations for a Single Audit or a state-mandated CPA audit, and can you hand off audit-ready records?
3. Who owns donor acknowledgments and the $250 written-acknowledgment and $75 quid pro quo disclosure rules?
4. How do you track the gross-receipts and asset figures that decide our Form 990 tier?
5. What happens to coverage if a staff member leaves?

What Are the Risks of Outsourcing Nonprofit Accounting?

The main risks are loss of visibility, weak internal controls, and choosing a provider without genuine nonprofit expertise. Each is manageable, but you should address it in the engagement, not after.

Guard against them by keeping board-level oversight of monthly financials, insisting on segregation of duties even with an outside team, and confirming the provider knows the compliance stakes. Those stakes are steep: failing to file the required 990-series return for 3 consecutive years automatically revokes tax-exempt status by operation of law under IRC Section 6033(j), effective on the due date of the third missed return, and the IRS has no discretion to reverse it. Smaller organizations that merely file late face $20 per day, capped at the lesser of $10,500 or 5% of gross receipts (indexed annually; figures as of 2026).

What this means for you: If your books already feel behind, or a grant, growth spurt, or audit is on the horizon, outsourcing is a right-sized way to add fund-accounting depth without a full-time hire. We help nonprofits keep defensible, audit-ready books and file the correct 990 on time. Contact Us to talk through what your organization needs. You can also review our nonprofit accounting work.

Frequently Asked Questions

Do Small Nonprofits Need a Bookkeeper?

Even the smallest nonprofits must maintain basic financial records and file annually — organizations with gross receipts normally $50,000 or less file the Form 990-N e-Postcard. Below that size formal bookkeeping is minimal, but someone still has to track gross receipts, because crossing $50,000 changes the return you owe.

What Bookkeeping Software Do Nonprofits Use?

Most nonprofits keep their books in general accounting software configured for fund accounting, so restricted and unrestricted net assets are tracked separately as FASB ASU 2016-14 requires. The software matters less than the setup: a chart of accounts and class structure that maps to your grants and programs is what makes the 990 and any audit straightforward.

What Are the Risks of Outsourcing Nonprofit Accounting?

The main risks are reduced day-to-day visibility, weaker internal controls, and hiring a provider without real nonprofit experience. Keep board oversight of monthly financials, require segregation of duties, and confirm the provider handles fund accounting, donor acknowledgments, and Form 990 readiness before you sign.
