- 1 · Import and categorize all transactions, every account.
- 2 · Reconcile each bank and card account to its statement — to the dong.
- 3 · Match payment-gateway and POS payouts to deposits.
- 4 · Review receivables: send anything unbilled, chase anything overdue.
- 5 · Enter all supplier bills, even unpaid ones — payables you can't see still exist.
- 6 · Post payroll, including employer contributions, not just net pay.
- 7 · Reconcile VAT: output and input tax against issued/received e-invoices.
- 8 · Update inventory and COGS if you carry stock.
- 9 · Book accruals, prepayments, and depreciation.
- 10 · Review the P&L against last month — explain every big swing or fix the booking error it usually is.
- 11 · Check the balance sheet: every line either reconciles to something real or gets investigated.
- 12 · Lock the period, file the documents, write a three-line summary of the month.
If steps 10–11 keep surfacing surprises, the problem is upstream in 1–9. A clean close is boring — that's the point.
