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.

Four phases · sixteen checks Done by the 10th
EVERY MONTH 1 · GET EVERYTHING IN 2 · RECONCILE & PROVE DIFF $0.00 3 · TRUE-UP THE PERIOD 4 · REVIEW & LOCK CLOSED BY THE 10TH

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.

A table comparing a five-check close with the full sixteen: a solo service business with one account enters the month, reconciles that account, reads both reports and locks the month on a fixed day, while a business with payroll, sales tax, several accounts and a lender also clears holding accounts, posts accruals and loan splits, ties out its liabilities, scans the agings and saves the proof.

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.

MARCH closed · proven APRIL closed · proven MAY — OPEN IF IT BELONGS HERE ERROR FOUND (it's from March) DOCUMENTED, DECIDED WITH THE CPA ✓ A CASUAL EDIT TO A CLOSED MONTH — CHANGES REPORTS ALREADY SENT
A March error found in May is documented first. With the CPA or controller it is either entered in the current period or handled as a prior-period adjustment or an amended filing; a casual edit to March would silently change reports already relied on.

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.

FAQ · Updated October 2026

The questions owners ask about closing.

Four phases, in order. Get everything in: bank feeds through month-end, all invoices and bills, payroll posted, owner-paid items captured. Reconcile and prove: every statement account — bank, card, and loan — reconciled to $0.00 difference, undeposited funds cleared. True-up the period: accruals and prepaids, loan splits, payroll and sales-tax liabilities tied to filings, suspense accounts emptied. Review and lock: P&L and balance sheet read against recent months, receivable and payable agings scanned, the closing date set, statements issued. The order matters — each phase only means something if the one before it held.
Completeness first, then proof, then adjustments, then review — because each step assumes the previous one. Reconciling before all transactions are in guarantees rework; adjusting accruals before accounts reconcile means adjusting numbers that may be wrong; reviewing reports before adjustments means reviewing a month that isn't finished. A painful close is a sign of steps run out of order, not of a missing checklist.
For a small business with current books and a settled routine: a few focused hours, finished within the first ten days of the new month. The standard to aim for: statements issued by the 10th, once records are in. If your close routinely eats days, that's diagnostic — look for months of unreconciled history underneath, a chart of accounts fighting you, or transactions still trickling in mid-close. The fix is rarely 'go faster'; it's repairing whichever earlier discipline is missing.
Settings → Advanced → Close the books sets a closing date, optionally password-protected. After that, any edit to a transaction dated on or before that date triggers a warning — or requires the password. QuickBooks records authorized changes in its Exceptions to Closing Date report. Without a lock, a stray edit or deletion months later silently changes reports you already relied on and breaks the reconciliation trail behind it.
You need the spine of it, not the ceremony. A solo business with one bank account and simple flows can honestly close in five checkpoints: everything entered, the account reconciled, loans split, a two-minute read of both reports, done monthly on a fixed day. What you shouldn't skip at any size is reconciliation and the monthly rhythm itself — a close you only run at tax time isn't a close, it's a year-end excavation.
Errors compound quietly, because nothing was being proven while they landed. A duplicate here, a miscategorized deposit there — each skipped month is another layer they settle into, and reports drift further from reality without looking any different. Catching up is genuinely harder than staying current, because now every fix has downstream months to ripple through. A few skipped months is a weekend of discipline; a year or more has had time to drift, which makes it a proper cleanup before any close can hold.

Rather have this run for you every month, with statements out by the 10th once records are in? That's the month-end close service. More guides: the guides hub →
