How do I collect an unpaid invoice from a nonprofit organization?
Collecting an unpaid invoice from a nonprofit — what changes and what stays the same
Short answer
Nonprofits have the same legal obligation to pay their invoices as any other business entity — their tax-exempt status does not affect their payment obligations under contract law. The practical difference is in what assets you can reach if you need to enforce a judgment: nonprofits do not have shareholders to hold personally liable, and many of their assets (restricted funds, endowments, donated property) may be legally protected from creditor claims. For amounts under small claims limits, the standard small claims process applies. For larger balances, escalation should focus on the nonprofit's board and executive director, who often respond quickly to the reputational implications of a collections action.
The legal framework is the same. A nonprofit that signs a contract and does not pay has breached that contract. You can demand payment, send a formal demand letter, file in small claims court, and obtain a judgment against the organization. None of that is different from collecting from any business.
The practical differences are in the asset picture. A nonprofit's assets are held for the organization's exempt purpose — many are restricted funds that can only be used for specific programs, and courts in some states protect those restricted funds from general creditor claims. This means a judgment against a nonprofit does not automatically give you the same ability to levy a bank account that you would have with a for-profit business. The general operating account is reachable; restricted grant accounts typically are not.
The escalation path that works best for nonprofits: go to the executive director and board directly. Nonprofit executives are acutely sensitive to reputational issues — a collections claim against a nonprofit can damage donor relationships, grant eligibility, and community standing in ways that financial consequences alone do not. A formal demand letter addressed to both the executive director and the board chair, stating that you will pursue collections if payment is not received by a specific date, typically produces payment from nonprofits that have been ignoring invoices.
Verify the organization's financial condition. Nonprofits must file Form 990 with the IRS annually, and those filings are public record (available on ProPublica Nonprofit Explorer). The 990 shows revenue, expenses, and balance sheet data. If the nonprofit is financially healthy and simply slow to pay, that tells you the money exists and the issue is process or priorities. If the 990 shows cash-flow problems or recent deficits, a payment plan may be more realistic than expecting a lump-sum payment.
State attorney general oversight: most states require nonprofits to register with the state attorney general and maintain certain standards for financial conduct. For significant unpaid balances (generally $10,000+), a complaint to the state attorney general's charitable trust division creates regulatory pressure that can be more effective than a civil lawsuit, particularly for organizations that depend on state grants or contracts.
