Why Nonprofit Finance Fails When It Depends on One Person

At most nonprofits, finance is one person.

Maybe it’s a bookkeeper who’s been there for years. Maybe it’s the operations manager who inherited the books. Often it’s the executive director, doing the reconciliations at night after everyone else has gone home. Whoever it is, they hold the whole thing: the transactions, the payroll, the reports, the funder relationships, the memory of why last year’s grant was coded the way it was.

And it kind of works. Right up until it doesn’t.

This is the norm, not a failure of planning

If your finance function rests on one person, you’re not doing anything unusual. Small nonprofits run lean and flat, budgets are tight, and a full finance team is a luxury most organizations can’t justify. So the work concentrates. One person ends up owning every step: authorizing spending, recording it, holding the assets, and reconciling the accounts.

No one designs the finance function that way on purpose. It evolves. A role that started as “keep the books” quietly grows into “run all of finance,” and because that person is capable and committed, the gaps never show. The organization mistakes their competence for a system.

That’s the trap. Competence isn’t a system. It’s a person. And people leave, get sick, burn out, and take time off.

The problem is the single point of failure

When one person is finance, the organization has a single point of failure sitting at the center of its money.

This is not hypothetical, and it is not rare. In a 2025 survey of nonprofit leaders, about 72 percent said they struggle with turnover in finance and accounting at least occasionally, and 38 percent called it frequent. When a finance role does open up, it stays open. The average time to fill one now runs to roughly five months. That is five months with no one closing the books properly, or with everyone else improvising around the gap.

And when that person walks out, they do not just leave a vacancy. They leave with the context. Why a particular funder wants reports in a particular format. Which grants are restricted and which are not. Where the workarounds are buried. Little of it is written down, because there was never time, and because it all lived in one head. The next hire, if you can find one, starts from a cold stop.

A finance function that only works when a specific person is in the chair is not a finance function. It is a dependency.

It is a control risk, not just a capacity risk

So far this has been about capacity. The bigger risk is control.

When one person does everything, there is no separation of duties. The same individual who approves a payment also records it, also holds the checkbook, also reconciles the account it came from. Every accountant knows why that is dangerous. With no second set of eyes anywhere in the chain, errors go uncaught, and in the worst case, so does fraud.

This is not a theoretical concern for nonprofits. The Association of Certified Fraud Examiners has found that nearly a third of nonprofit fraud cases happen precisely because one person handles multiple financial tasks without oversight. Auditors know this, which is why a one-person finance function is one of the first things they flag. Funders are starting to ask about it too.

Segregation of duties is the oldest control in accounting for a reason. You do not solve it with trust. You solve it with structure.

Why this matters more right now

Nonprofit finance has always been demanding. Right now it is unforgiving.

Since early 2025, the federal government has frozen or canceled an estimated $425 billion in funding. The Urban Institute found that about a third of nonprofits reported some kind of government funding disruption in the same period: a loss, a freeze, a delay, or a stop-work order. For organizations working in legal aid, advocacy, and civil rights, this is not background noise. Legal Services Corporation funding, which underwrites civil legal aid across the country, has been cut and repeatedly threatened.

When money is frozen, clawed back, or released month to month, the finance function has to move fast and be right. Budgets get rebuilt on short notice. Restricted funds have to be tracked to the dollar. Reports have to hold up to scrutiny that is suddenly much closer. A single overstretched person, however good, is the most likely place for that to break, at the exact moment the organization can least afford it.

The fix is structure, not a better hire

The instinct, when the one-person setup starts to strain, is to find a better person. A more senior hire. Someone who can finally get on top of it all.

That instinct is understandable, and it is wrong. Hiring one excellent person to carry the whole function just rebuilds the same dependency with a higher salary. The organization is still one resignation away from the same crisis.

The real fix is to stop relying on any single person at all. That means separating the duties so no one owns a transaction end to end. It means writing the process down so the knowledge lives in the system, not in someone’s memory. It means putting a layer of oversight above the day-to-day work, so accuracy is owned and checked rather than assumed.

That is what a real finance function looks like: predictable, documented, and resilient to any one person having a bad week or a last day. That is the difference between a nonprofit that spends its energy on its mission and one that spends it worrying about the numbers.

If your finance function currently runs on one person, that is not a criticism. It is the most common setup there is. But it is worth knowing what you are carrying, and worth building something that does not depend on you being there to hold it.
