The month-end close checklist, the working version.
Not a listicle — the actual sequence to run on your books every month: get everything in, reconcile and prove, true-up the period, review and lock. Usable as written, in order, by an owner.
Trimmed to what a small business genuinely needs. General education, not advice for your specific situation.
Quick answer
Aim to issue statements by the 10th of the following month, in a few focused hours once the records are in. If a close routinely takes days, the cause sits upstream: unreconciled history, a chart of accounts that fights you, or transactions arriving mid-close. Once a month is proven, set the closing date so later fixes post forward.
The checklist
Four phases, sixteen checks — in the order that works.
Run top to bottom. Every item is pass/fail on purpose: a check you can't answer cleanly is telling you where this month's work is.
Working template — fill in your own figures. Not client data.
Phase 1 · Get everything in
Nothing can be proven while transactions are still missing.
Bank feeds pulled through month-end
Every connected account's feed added or matched through the last day of the month — no pending pile.
All invoices and bills entered
Revenue you billed and expenses you owe, in the ledger with the right dates — even if unpaid.
Payroll posted for the full month
Every run in the books, with employer taxes — not just the net checks that hit the bank.
Receipts and owner-paid items captured
Business expenses paid personally, mileage, petty cash — the items no feed will ever deliver.
Phase 2 · Reconcile and prove
The anchor phase — every balance tied to a source document.
Every statement account reconciled
Checking, savings, every credit card, every loan — each to its own statement, difference $0.00. The full method is its own guide.
Reconcile undeposited funds to identifiable receipts awaiting deposit; investigate stale, duplicate or unmatched items.
A receipt still waiting for its deposit belongs there; one that can't be matched to a real receipt is a symptom worth chasing now.
Beginning balances intact
If any account's opening balance shifted since last close, a reconciled transaction was edited — repair before proceeding.
Phase 3 · True-up the period
Income and expense land in the month they belong to.
Accruals and prepaids adjusted
The insurance paid annually, the retainer billed quarterly — spread to the months they actually cover.
Loan payments split principal vs interest
Per the amortization schedule — otherwise the P&L overstates expense and the loan balance never moves.
Payroll and sales-tax liabilities tied out
Liability accounts agree with what the filings say you owe — the two places errors get expensive.
Suspense emptied
Ask My Accountant, Uncategorized Expense, Opening Balance Equity — every parked transaction categorized for real.
Phase 4 · Review and lock
A second look, then a period that can't quietly change.
P&L scanned against recent months
Margin roughly consistent, no expense line suddenly doubled, nothing negative that shouldn't be — surprises get explained, not shrugged at.
Balance sheet read line by line
Every balance either matches a statement or has a story you can say out loud. The one that doesn't is next month's cleanup, caught early.
Receivable and payable agings scanned
Invoices that realistically won't be collected, and bills showing unpaid that actually cleared — both distort the reports until they're flagged and fixed.
Close date set and locked
In QuickBooks Online: set the closing date with a password, so a completed period is protected from casual changes; authorized changes show in the Exceptions to Closing Date report.
Statements issued and proof saved
P&L, balance sheet, and reconciliation reports filed where you can find them — the month is done, and it stays done.
Phase 2 is the point where unreconciled balances become visible. It has its own full walkthrough: how to reconcile in QuickBooks Online, step by step → If the checklist keeps failing at the same item month after month — undeposited funds never empty, a liability that never ties out — that's not a close problem anymore; it's a cleanup announcing itself.
Figure data as a table
| Phase | Solo service business: one account, no payroll or loans | Payroll, sales tax, several accounts, a lender |
|---|---|---|
| Get everything in | Everything for the month entered | Feeds through month-end, invoices and bills, every pay run, owner-paid receipts |
| Reconcile and prove | The one bank account reconciled | Every statement account to $0.00, Undeposited Funds cleared, opening balances intact |
| True-up the period | Not needed at this size | Accruals and prepaids, loan splits, payroll and sales-tax liabilities, suspense emptied |
| Review and lock | Both reports read, the month locked on a fixed day | Both reports read, agings scanned, closing date set, proof saved |
A framework · the last check
What "closed" protects after the close.
A closing date protects a completed period from casual changes. If an error is discovered later, do not edit the closed period casually: document it and determine with the client's CPA or controller whether it belongs in the current period or needs a prior-period adjustment or an amended filing. QuickBooks records authorized changes in its Exceptions to Closing Date report. That discipline is what lets a month keep its proof: a transaction from March edited in May makes today's reports disagree with the ones already sent, breaks the reconciliation trail behind them, and moves next month's opening balance before you start.
QuickBooks Online sets the closing date under Settings → Advanced, ideally with a password, and lists every authorized change to a closed period in its Exceptions to Closing Date report, so a later change is visible rather than silent. It is the final check on the list. A locked close gives the bank or CPA a stable version to review; their own reporting or assurance requirements still control. How financial statements are prepared from a locked close is on their own page.
How much you need
How much of this do you actually need?
Less than the full sixteen, possibly. A solo service business with one bank account, no payroll, and no loans can run an honest close in five checks: everything entered, the account reconciled, the two reports read for two minutes, the month locked, done on a fixed day. That's a real close — small, not sloppy — and if that's you, take the five and skip the ceremony.
What doesn't scale down is the rhythm and the proof: monthly, reconciled, locked. And there's an honest tipping point in the other direction — payroll plus sales tax plus multiple accounts plus a lender who wants statements, and the close stops being a good owner-task and starts costing you the exact hours you're in business to spend elsewhere. That's what our month-end close service covers: the checklist run for you, with your numbers issued by the 10th, once records are in, and delivered through monthly bookkeeping. The close is checked before the numbers leave us. Reading what the close produces is its own skill — the financial statements guide covers that half.
