Step-by-Step QuickBooks Cleanup Checklist

Step 1

Scope & Snapshot

  • Identify months of backlog and accounts to reconcile.
  • Export current Trial Balance, AR Aging, AP Aging, and Undeposited Funds.
  • Record opening metrics in the template.
Step 2

Bank/Credit/Loan Reconciliations

  • Reconcile each account month-by-month to statements.
  • Investigate service-charge/interest variances; post missing entries.
  • Document unreconciled items and resolutions in the log.
Step 3

Undeposited Funds & Suspense Accounts

  • Match payments to deposits; remove duplicates.
  • Clear Undeposited Funds to zero; resolve “Ask My Accountant”/misc suspense.
  • Attach support (screenshots, bank proof) in the workpaper folder.
Step 4

Categorization & Rules

  • Normalize vendors/customers; merge duplicates.
  • Build bank rules for recurring transactions (ads, SaaS, utilities).
  • Reclassify uncategorized income/expense; document bulk changes.
Step 5

Accounts Receivable (AR)

  • Apply payments/credits correctly; remove negative customers.
  • Write off uncollectible balances with memo and policy reference.
  • Ensure AR Aging ties to the GL at period-end.
Step 6

Accounts Payable (AP)

  • Match bills to payments/credits; remove negatives/vendors with credits.
  • Standardize approval flow (maker/checker) going forward.
  • Ensure AP Aging ties to the GL at period-end.
Step 7

Payroll, Sales Tax, and Liabilities

  • Tie payroll clearing accounts to payroll reports; fix stale liabilities.
  • Verify sales-tax filings/returns; post adjustments where required.
  • Attach third-party statements to the month folder.
Step 8

Inventory & COGS (if applicable)

  • Reconcile item quantities/values to inventory system.
  • Correct mappings (fees, discounts, shipping) from e-commerce apps.
  • Post COGS/adjustments with workpapers.
Step 9

Adjusting Entries (Accruals, Prepaids, Depreciation)

  • Post monthly accruals/prepaids with schedules.
  • Record depreciation/amortization per policy.
  • Add memo links to supporting schedules.
Step 10

Go-Forward Monthly Close

  • Generate P&L, Balance Sheet, AR/AP Aging; confirm they match subledgers.
  • Prepare a variance note (what changed and why).
  • Save final Trial Balance and reports to the period folder.
Step 11

CPA Review & Period Lock

  • Have a CPA review reconciliations, JEs, and variance notes.
  • Lock the period to prevent back-posting.
  • Publish a “clean as of” date in your close calendar.

Common QuickBooks Cleanup Mistakes (and How to Avoid Them)

  • tick Deleting transactions instead of reversing them → Always preserve audit trail.
  • tick Reconciling to bank feed balances → Reconcile to statements, not feeds.
  • tick Ignoring Undeposited Funds → Clear to zero or you’ll double-count revenue.
  • tick Letting AR/AP go negative → Fix applications/credits before tie-out.
  • tick Skipping period locks → Prior months drift; lock after CPA review.

When to DIY vs Hand It Off

DIY fits light backlogs (≤3 months) with few accounts.

Hand it off when:

  • tick 4-12+ months behind, inventory or multi-entity complexity, broken app mappings, or lender deadlines.
