Fast path

Preparing for a GSA audit means proving that your pricing, sales reporting, catalog, and compliance records match your contract terms before the auditor asks for them.

Before you start

What makes this process go smoothly

  • Audit readiness is a records discipline, not a last-minute scramble.
  • Pricing support, sales reconciliation, and TAA evidence are common pain points.
  • If something is off, fix the underlying process as well as the immediate document gap.

Pricing records

Commercial discounts, awarded rates, modifications, and any basis-of-award changes are traceable.

Sales records

Quarterly reported sales tie back to internal financial and order data.

Catalog records

Products, labor categories, and terms shown to buyers match the awarded contract.

Compliance evidence

TAA support, mass mod acceptance, and internal controls can be shown without scrambling.

The records stack you want ready

Audit prep is not something you do once an audit notice arrives. The strongest contractors prepare by running the contract in a way that keeps pricing, sales records, sourcing support, and catalog data organized all year. That turns audit response from a scramble into a records exercise.

The records stack you want ready

  • Sales reporting records that reconcile cleanly to internal data.
  • Pricing and discounting support tied to the contract logic.
  • Catalog and offered-item records that match the awarded contract.
  • TAA or origin support where applicable.
