What Is Fund Accounting? A Plain-English Guide for Nonprofits

Short answer: fund accounting is bookkeeping that keeps money in separate “buckets” by purpose instead of one big total, so a grant, a memorial gift, or a building-campaign donation never gets spent on something the donor didn’t approve. It’s standard for nonprofits, churches, and government entities because accountability is the whole job, not just the bottom line.
You don’t need special software to start. You need to stop treating your bank balance as your budget.
It’s Sunday night and Dana — I’ll call her Dana — is the volunteer treasurer for a nine-person after-school reading program, staring at a spreadsheet titled “Money 2026.” One column holds a $600 bake-sale deposit, a $5,000 foundation grant earmarked for new books only, and $1,200 in general donations from the newsletter. All three sit in the same checking account and, until tonight, the same spreadsheet column too.
She isn’t bad at this. She just built a system for tracking one bucket of money, and the program now has three.
That’s the entire idea behind fund accounting, and almost nobody explains it without three pages of accounting-department language first. Here it is without that.
What fund accounting actually means
Regular business bookkeeping answers one question: did we make money? Fund accounting answers a different one: did each pot of money go where it was supposed to? That shift — from profitability to stewardship — is the whole method.
- A fund is its own mini set of books. Each one tracks its own income, expenses, and balance, even though the actual cash usually sits in one shared bank account.
- It matters most when money comes with strings attached. A grant with a stated purpose, a gift given “in memory of” someone, a capital campaign for a specific project — each is a promise, and the books have to prove the promise was kept.
- It isn’t optional once the money is restricted. You can choose not to bother with fund accounting, but you can’t choose not to honor a donor restriction — the funds are the mechanism for proving you did.
Restricted funds, unrestricted funds, and why donors care
Every dollar that comes in falls into one of a few categories, and the category is set by the donor, not by you.
- Unrestricted funds. General operating money. Spend it on rent, payroll, or printer paper — anything that fits the mission.
- Temporarily restricted funds. Earmarked for a purpose or until a date. Dana’s $5,000 book grant stays in this bucket until it’s spent on books, or the grant period ends.
- Permanently restricted funds. An endowment. The principal stays invested forever; only what it earns each year can be spent.
- Board-designated isn’t the same thing. A board can vote to set money aside for a future project and vote again to change its mind. A donor restriction doesn’t move that easily — it survives the board’s vote.
A grant letter that sounds official isn’t automatically a restricted fund, either. Read what it actually says. If there is no stated purpose and no time limit, the money is unrestricted no matter how formal the paperwork looks.

How it’s different from the bookkeeping you already know
If you’ve run a small business, you know a profit and loss statement and a balance sheet. A nonprofit’s books carry the same discipline but different labels, because there’s no owner and no profit motive to report against.
- Net assets, not owner’s equity. Nonprofit financial statements group everything into net assets with donor restrictions and net assets without them — two categories instead of the profit-driven equity accounts a for-profit uses.
- A statement of activities, not a P&L. Same idea — income minus expenses over a period — but broken out by fund, so a reader can see the restricted money and the general money separately.
- Revenue is recognized when it’s received, not spent. A $5,000 grant counts as revenue the day it arrives, even though it might take a school year to spend it on books. What changes over time is whether it’s still restricted or has been released.
- One deposit can touch several funds. A single fundraising-night deposit might be part ticket sales (unrestricted) and part a designated gift (restricted) — the split happens at the point of entry, not later.
Setting it up without hiring anyone yet
Most small nonprofits and churches don’t need dedicated fund-accounting software on day one. They need a system and the discipline to use it monthly.
- 1. One spreadsheet tab per fund. Track deposits and withdrawals per fund, and reconcile the total against the single bank statement every month. Below a certain size, this is genuinely enough.
- 2. Use classes or locations if you’re on QuickBooks. QuickBooks Online Plus and Advanced let you tag every transaction with a class, then run a report filtered by fund — no extra software required at this stage.
- 3. Keep the grant letters and receipts, not just the totals. Exempt organizations are expected to keep records that document the source of every receipt and expenditure, not just a summary number. A folder per fund with the agreement letter inside solves most of this on its own.
- 4. Reconcile monthly, not at tax time. Commingling almost never happens in one dramatic mistake. It happens in small, unreviewed decisions across eleven months, discovered on the twelfth.
If that’s your whole situation — one bank account, a handful of funds, and a volunteer willing to spend twenty minutes a month on it — a spreadsheet and a habit are genuinely enough. We’d tell you the same thing on a call. See how a first month with us actually runs if you want to compare it against doing this yourself.
Recording donations so the numbers hold up
Most fund-accounting mistakes happen at the moment a donation is entered, not later. Get this part right and the rest is mostly maintenance.
- Record the restriction at the gift, not at the spend. The moment a check with “for the building fund” in the memo line clears, it belongs to that fund — not whenever someone gets around to categorizing it.
- In-kind donations count too. Donated equipment, supplies, or professional services need an honest fair-value estimate and a note of who gave what, even though no cash changed hands.
- Track the release, not just the receipt. When the $5,000 book grant is actually spent on books, that gets logged as a release from restriction — the money moves from “restricted” to “spent as promised,” and that entry is your proof.
- When in doubt, ask the donor. A vague memo line (“for the kids”) is worth a two-line email asking what they meant. It’s faster than guessing wrong and re-explaining it later.

When a bookkeeper or accountant actually earns their fee
There’s a point where the spreadsheet stops being enough, and it usually isn’t about size alone — it’s about complexity.
- Multiple grants with different reporting deadlines. Once you’re tracking three funders who each want a report in a different format on a different schedule, a dedicated bookkeeper stops being overhead and starts being time back.
- You’ve added payroll. Fund tracking plus employer payroll tax deadlines is where volunteer treasurers most often fall behind.
- You’re near the Form 990 filing thresholds. The IRS requires the full Form 990 once gross receipts reach $200,000 or total assets reach $500,000, with simpler forms below that. The full return is a different level of documentation than the e-Postcard most small nonprofits start with.
- You’re approaching $1,000,000 in federal awards. Under federal Uniform Guidance, an organization that expends $1,000,000 or more in federal awards in a fiscal year needs a Single Audit — and that has to be signed off by a CPA. Njock is an accountant, not a CPA, so at this stage we’ll say so plainly and bring in a CPA partner rather than pretend otherwise.
Short of that threshold, monthly bookkeeping and tax preparation for a small nonprofit or church is ordinary work for us — the same bookkeeping and tax services we run for small businesses, applied to fund reporting instead of a profit and loss.
What it costs to keep it all in one bucket
The immediate risk is small and specific: a restricted grant gets spent on the wrong line item, and now you either return the money or scramble to cover it from somewhere else. Annoying, but recoverable.
The slower risk is the expensive one. Eleven months of unreviewed decisions turn into a twelfth month spent reconstructing an entire year from bank statements and memory — usually right before a Form 990 filing or an audit, when there’s no slack left in the calendar.
There’s no official price tag on a mess, but do the arithmetic yourself: a CPA reconstructing a year of commingled transactions after the fact bills by the hour, and that clock runs a lot longer than the one for keeping monthly records straight in the first place. A $299-a-month bookkeeping habit is the cheaper problem, every time.
And the part that doesn’t show up on any invoice: donor trust doesn’t come back with an amended report. A funder who gets asked to overlook a misused grant remembers it longer than they remember the correction.
Frequently asked questions
- What is fund accounting in simple terms?
- It’s bookkeeping that groups money into separate “buckets” — funds — by purpose or restriction, instead of tracking everything as one bank balance. A $5,000 grant for new books, a $600 bake-sale deposit, and $1,200 in general donations each get tracked on their own, even if they all sit in the same checking account.
- Is fund accounting only for nonprofits?
- Mostly, yes. Nonprofits, churches, and government entities use it because donors and grantors attach conditions to their money and the organization has to prove the conditions were honored. A typical small business doesn’t need it — there’s no donor to answer to, just a profit-and-loss statement.
- What’s the difference between restricted and unrestricted funds?
- Unrestricted funds can be spent on anything that fits the mission. Restricted funds come with a donor-specified purpose, a time limit, or both — spend a restricted gift on the wrong line item and, technically, you owe that money back to its original purpose. Permanently restricted funds (an endowment) keep the principal invested forever; only what it earns can be spent.
- Do small churches really need fund accounting?
- Once there’s more than the general offering — a building fund, a missions trip, a memorial gift — yes, in practice if not always by law. Small churches can track a handful of funds in a spreadsheet: general operating, building, missions. Keep the list short and reconcile it monthly against the bank statement.
- Can I do fund accounting in QuickBooks?
- Yes, for a small organization. QuickBooks Online Plus and Advanced both support “classes” or “locations,” which you can use to tag transactions by fund and run a report per fund. Once you’re juggling a dozen grants with different reporting deadlines, dedicated nonprofit accounting software usually pays for itself.
- What happens if a nonprofit doesn’t separate its funds?
- The immediate risk is spending restricted money on something a donor or grantor didn’t approve, which can mean returning the funds or reclassifying other income to cover the gap. Do it repeatedly and it shows up as an audit finding — and in serious, sustained cases, it can put a 501(c)(3)’s tax-exempt status at risk.
- Does my nonprofit need an independent audit?
- It depends on size and funding source, not on being a nonprofit. Under federal rules, an organization that expends $1,000,000 or more in federal awards in a fiscal year needs a Single Audit. Separately, gross receipts and asset levels determine which version of Form 990 you file with the IRS. Many states also set their own, often lower, audit thresholds for charitable organizations — worth checking against your state’s specific rule.
- Does NJ’s handle fund accounting for nonprofits and churches?
- Yes — monthly bookkeeping and tax preparation for small nonprofits and churches is work we do regularly. One honest limit: Njock is an accountant, not a CPA, and a required independent Single Audit has to be signed off by a CPA. If your organization is at that stage, we’ll say so upfront and bring in a CPA partner or refer you out.
