--A pre audit is where the inspecting firm comes in and gives you some advice on what to fix, check etc.,A post audit is where the agency comes in to see if you have fixed the problems or came up with answers to the questions they asked during the audit itself.
--Pre - audit is an audit approach where payment vouchers are reviewed by audit staff before final payment is made. Post Audit is an audit approach where supporting documents are reviewed weeks / months after the transactions have taken place.
