CPSR compliance guide

I recently had to figure out CPSR compliance for our state contract work, and this guide was a lifesaver. It walks through the entire Purchasing System Review process step by step, explaining what auditors look for and how to avoid common pitfalls. The practical examples made it easy to understand the rules without getting bogged down in jargon.
