Our mission

What does AuditRadar exist to do?

A more transparent audit market helps nonprofits build trust, operate with integrity and advance their missions. AuditRadar exists to bring clarity to a fragmented market — using public data, versioned rules and a method anyone can read.

Our story

  • Increase transparency

    Make auditor changes and publicly posted RFPs easy to find, with the filing or the issuer page behind each one.

  • Empower professionals

    Give CPA firms the evidence they need to pursue mission-aligned work, without a scraped list or an invented score.

  • Support a stronger nonprofit sector

    Help nonprofits reach the audit firms that fit them, and let a public record stay a public record.

Who is it built for?

  • Firms building a nonprofit audit practice in one state
  • Firms replacing small engagements with larger single audit work
  • Partners who already research the Clearinghouse by hand
  • Marketing or BD staff who need that research organised
How AuditRadar works

How does public data become a review list?

We collect public filings, compare each account against its own prior year, check every solicitation on the issuer's own page, and publish the evidence next to the result.

See it in action

  1. Collect public data

    Single audit filings from the Federal Audit Clearinghouse, e-filed Form 990 returns, and solicitations posted on the issuer's own page.

  2. Compare and classify

    Deterministic, versioned rules compare each account against its own prior filing. There is no model score and no prediction.

  3. Verify the source

    Each solicitation is checked against the issuer's own page on every crawl, at least weekly, and the date it was checked is printed beside it.

  4. Deliver the evidence

    Rows, alerts and exports carry the report ID and the link, so you can open the filing a signal came from.

Our data sources

Where does the data come from?

AuditRadar uses only publicly available information from official sources. We never use private, non-public or confidential data, and nothing behind a login or a paywall is collected.

View all data sources

  • Federal Audit Clearinghouse

    Single audit filings, refreshed weekly. Every account row links back to the report it came from.

    Auditor changes

  • IRS Form 990 e-file data

    The two most recent e-filed Form 990 or 990-EZ returns of each nonprofit in the Clearinghouse data, refreshed weekly.

    Entity context

  • Issuer-posted solicitations

    Read from the issuer's own page or document, and re-checked there on every crawl, at least weekly.

    RFP opportunities

  • 2 CFR part 200, subpart F

    The federal rule that creates those filings, including the single audit threshold and the submission deadline.

Our methodology

How is the data verified?

We follow a documented method, so you can see exactly how a row was found, classified and checked. We never claim an organization intends to change providers — we show what the public record says, and when it changed.

Learn about our methodology

What we always do

  • Link the source on every row, and print the date it was last checked.
  • Use deterministic, versioned rules. There is no model score and no prediction.
  • Print "$0 reported" rather than a bare zero, and "Not available" for a blank.
  • Suppress a comparison we cannot make confidently rather than guess it.
  • Publish a directory page only once enough has been observed to be worth reading.

What AuditRadar does not claim

  • We do not provide audit, tax or legal advice.
  • We do not state that every RFP or auditor change has been captured.
  • We do not have access to non-public or confidential data.
  • We do not endorse or recommend any audit firm.
  • We are not affiliated with any government agency.

Built on public data

Built for professionals. Backed by a commitment to accuracy and to the public record.

A smarter, more transparent nonprofit sector.

Our story

Who built AuditRadar, and why?

AuditRadar is an independent publisher of nonprofit audit data. We are not owned by, funded by or affiliated with any audit firm, and no firm can pay to appear, rank higher or change what a page says.

The Federal Audit Clearinghouse publishes every single audit and answers one organization at a time. Comparing two years of filings across a whole state is manual work that has to be redone every cycle. AuditRadar does that comparison once and publishes the evidence behind each result.

Contact the team

Built around how audit work is really researched — one state, one filing year, one report at a time.

A commitment to transparency: every rule is published, and every number carries the date it was verified.

Public data belongs in public view — organised well enough that the nonprofit sector benefits too.

Every figure comes from a public filing, or from a solicitation read on the issuer's own page. Nothing on this site asks to be taken on trust.
