How to Find Nonprofit Clients: A Prospecting Playbook for Accounting Firms

The short version

How to find nonprofit clients, in one line: start from public records that show a change in a nonprofit's finance workload, confirm the fit, then write one specific, honest, compliant message.

• Federal awards on USAspending.gov show who just received grant money. Agencies must report financial assistance within two weeks of the award transaction, and the site updates daily.
• Single Audit filings in the Federal Audit Clearinghouse (FAC) show who spent $1,000,000 or more in federal awards in a fiscal year starting on or after October 1, 2024, and whether the auditor reported findings.
• Form 990 returns, through the IRS or ProPublica Nonprofit Explorer, show size, government grants, outside accounting fees, and audit status.
• State charity registries, such as California's and New York's, publish annual financial filings.
• Finance job postings and grant announcements add timing. We treat both as softer signals.
• Commercial email to a nonprofit is covered by the CAN-SPAM Act. The FTC says the law makes no exception for business-to-business email.

Why public signals beat a purchased list

Our interpretation: a list of every nonprofit in your region tells you who exists, not who has a reason to talk to you this quarter. A public signal does. A new multi-year federal award, a first Single Audit, a repeat finding, or a controller vacancy each points to a specific finance task. That gives you a reason to write that the reader will recognize as true, and it keeps volume low enough to research each organization properly.

How to find nonprofit clients: six public signals

1. Federal awards on USAspending

USAspending.gov's Advanced Search filters include action date, award type, awarding agency, place of performance, recipient name or code, and assistance listing, and results can be downloaded from the top right of the page.

Timing matters. Agencies must submit financial assistance data within two weeks of the award transaction (loans within 30 days), and the new data is published the day after submission. So a grant signed today should usually be searchable within a few weeks.

Two cautions. An obligation is a promise to spend; an outlay is actual spending. Neither tells you what the nonprofit expended in its own fiscal year. Our federal award data guide walks through the filters, and our new awards watch is built around this signal.

2. Single Audit filings on the FAC

A nonprofit that expends $1,000,000 or more in federal awards in a fiscal year starting on or after October 1, 2024 must have a Single Audit. For fiscal years that started earlier, the threshold was $750,000. The reporting package is due within 30 calendar days after the auditee receives the auditor's report or nine months after the end of the audit period, whichever is earlier (2 CFR 200.512(a)(1)). The FAC makes reporting packages public, with a narrow exception for Indian Tribes that opt out.

The FAC search lets you filter by audit year (data goes back to 2016), UEI or EIN, assistance listing number, state, audit findings, fiscal year end month, type of compliance requirement, entity type, passthrough name, and FAC acceptance date. The FAC says it accepts and releases audit data immediately upon final submission, so an acceptance date filter is a practical way to see recent filings.

Useful patterns, as interpretation: a first filing after years of none, findings on reporting or allowable costs, and the same finding repeated. Our guides to reading Single Audit findings and the $1 million threshold cover each, and the Single Audit checker applies the threshold by fiscal year.

3. Form 990 via the IRS and ProPublica

An exempt organization must make its annual return, including Form 990, available for public inspection for three years. The IRS Tax Exempt Organization Search covers Form 990 series returns and 990-N records, and the IRS publishes e-filed Form 990 series returns as bulk XML downloads. ProPublica's Nonprofit Explorer adds summary financials, full returns, and links to audits copied from the FAC.

Lines worth reading first:

• Part VIII, line 1e: grants from local, state, federal, and foreign governments.
• Part IX, line 11c: accounting and auditing fees charged by outside firms and individuals.
• Part XII, line 3a: whether a federal award required an audit under 2 CFR Part 200, Subpart F. Note the current instructions still cite $750,000.

Organizations with gross receipts normally of $50,000 or less may file the Form 990-N e-Postcard instead, which carries no financial detail. Our Form 990 qualification guide goes line by line.

4. State charity registrations

Many states keep their own charity filings, and they can be more current or more local than federal data. In California, the Attorney General's Registry of Charities and Fundraisers requires charities to register and file annual financial disclosure reports, subject to limited exceptions, and its Registry Search Tool lets the public view and download filings, including copies of Forms 990. In New York, the Charities Bureau registry search shows annual financial reports filed in the last five years once the Bureau has reviewed them; some charities, such as religious organizations, may be exempt from registering.

Our interpretation: use state registries to confirm a legal name and EIN, check registration status, and find organizations whose federal footprint is small. Rules differ by state, so check the registry where your prospects are based.

5. Job postings for finance roles

This signal is interpretation from start to finish. A posting for a controller, grants accountant, or finance director tells you the organization has an open finance seat. It can mean growth, turnover, or a plan to bring work in house. Read the posting for clues (grant compliance duties, audit support, systems) and note the date. Treat it as a reason to offer interim or project support, not as proof of a problem.

6. Grant announcements

Our interpretation: agency and foundation announcements often name recipients before USAspending has a record. Use them for timing, then confirm the amount and period once the award appears. Grants.gov forecasts are earlier still, but Grants.gov states that a forecast is not guaranteed to become a funding opportunity announcement. Neither a forecast nor an open opportunity names a winner.

How to qualify a nonprofit prospect

Qualifying is where a signal becomes a prospect. Our interpretation of a workable test, in order:

1. Fit. Size, sector, and location match the work you do well. Confirm the legal entity and EIN or UEI so the award, the audit, and the 990 belong to the same organization.
2. Trigger. At least one dated, public event from the last few months: a new award, a recent FAC acceptance, a finding, a finance vacancy.
3. Capacity signal. What the 990 shows about the finance function: a paid finance officer or none, outside accounting fees, audit status.
4. Timing. Fiscal year end month, from the 990 or the FAC, tells you when audit preparation and the Single Audit deadline land.
5. Contact. The FAC data collection form must be signed by a senior-level representative of the auditee, such as a director of finance or chief financial officer (2 CFR 200.512(b)(2)). The 990's Part VII lists officers. Neither is an email address; find the right person through the organization's own website.

Label every claim before you write a word.

• VerifiedWhat a public record states. "The FAC shows a 2025 audit year submission with findings."
• InferredA reasonable reading. "Reporting work likely increased with this award."
• UnknownCurrent staff, existing advisers, budget, and whether they want help.

If a prospect has no trigger, keep it on a watch list rather than writing now.

Ethical, CAN-SPAM-compliant outreach

The rules. The FTC's CAN-SPAM compliance guide says the Act covers any email whose primary purpose is to advertise or promote a commercial product or service, and that it makes no exception for business-to-business email. Its main requirements:

• No false or misleading header information.
• No deceptive subject lines.
• Identify the message as an ad, clearly and conspicuously.
• Include a valid physical postal address.
• Give a clear way to opt out of future marketing email, keep it working for at least 30 days after sending, and honor requests within 10 business days.
• Do not sell or transfer the addresses of people who opted out.
• If someone else sends for you, both companies may be held responsible.

The FTC lists penalties of up to $53,088 for each separate email in violation, and it names harvesting email addresses and generating them through a dictionary attack among the practices that can bring criminal penalties.

Our interpretation of good practice, beyond the floor:

• Write one-to-one, about one public fact, and cite where it came from.
• Do not diagnose. "I saw your FAC filing for fiscal 2025" is accurate. "Your books need help" is an assumption.
• Do not imply a connection to a federal agency, an auditor, or a funder.
• Use addresses the organization publishes for business contact, never guessed or scraped ones.
• Keep the ask small: a short call, a checklist, or a second opinion.
• Professional rules for CPA firms and state laws may add requirements; check them.

Illustrative opener, not a template to send unchanged: "I noticed on USAspending that your organization received a three-year HHS cooperative agreement this summer. We help nonprofits set up grant tracking and drawdowns for new federal awards. If it would help, I can send a one-page closeout and reporting calendar. Reply 'no thanks' and I will not write again." Add your postal address, an advertising disclosure, and a working opt-out.

A weekly prospecting routine

Our interpretation of a sustainable cadence for a small firm:

1. Monday: run saved USAspending and FAC searches for your states and sectors, limited to the past week.
2. Tuesday: pull the latest 990 and state registry record for each new name.
3. Wednesday: qualify, label evidence, and drop anything without a trigger.
4. Thursday: write five or fewer messages, each with one cited fact.
5. Friday: log replies and opt-outs, and process every opt-out the same day.
