How to use this checklist

Use the onboarding checklist as the first request record, then convert recurring items into the monthly close process.

  1. 1Send the checklist after the engagement is signedSend it before kickoff so access issues and historical file gaps surface early.
  2. 2Assign each item to a client ownerMark who can provide banking access, payroll files, tax returns, and prior books instead of sending one broad request to one person.
  3. 3Review files before the first bookkeeping cycleCheck that access works, files cover the right periods, and historical balances support the first close or cleanup.
  4. 4Move recurring items into the monthly checklistOnce onboarding is complete, turn statements, payroll reports, and receipts into the client's recurring close request.
