The single audit wants evidence
Your financial statement auditor already asks whether the numbers are fairly presented. A single auditor adds a second question for each major program: did you follow the award's terms? That means costs that are allowable, incurred inside the period of performance, bought under written procurement procedures and charged to the award on a basis you can document. The auditor selects samples. The support for each one has to be on file already, because it cannot be recreated convincingly a year later.
If you are unsure whether you are in scope this year, the Single Audit Threshold Checker gives a general reading in a few minutes. Your auditor makes the determination.
What we test first
- Personnel charges. We compare the payroll allocated to each award with timesheets or activity records, pay period by pay period.
- Period of performance. We scan every grant-coded transaction for costs dated before the award began or after it ended.
- Unallowable costs. Entertainment, alcohol, fines and lobbying costs coded to a federal class or project are flagged for review.
- Procurement and conflicts. Purchases above your thresholds are matched to quotes, bids, conflict disclosures and an exclusion check in SAM.gov.
- Subawards. Agreements with partner organizations are classified as subawards or contracts, and each subaward is checked for required terms and monitoring.
Policies should describe real work
Written policies are a requirement of 2 CFR 200, but a policy that describes a process nobody follows becomes its own finding. We write procurement, conflict-of-interest, cost allowability, time-and-effort, equipment and subrecipient monitoring policies around how your team actually works, then train the people who will follow them. The single audit readiness checklist lists the documents auditors usually request first, and our Grant & Uniform Guidance Compliance work produces them.
As of November 2026 the OMB proposal to rewrite 2 CFR 200 is not final. We write to the current text and note the sections the proposal would change, so your policies stay current either way.
For a worked example, read the illustrative scenario The first single audit, which follows a community health nonprofit from its first projection above $1,000,000 to a rehearsed audit.
