The first time I owned a month-end close, I closed it twice.
Not on purpose. I thought I was done, sent the numbers around, and then a vendor invoice showed up two days later for work that happened in the month I’d just “closed.” So I reopened it, booked the accrual, re-ran the reports, and sent a sheepish “use this version instead” email. Classic.
I’m Yuval, founder of Glitter AI. We work with a lot of finance teams, controllers, and office managers running the books at small and mid-size companies. Of every process I see, closing the books is the one that gets done from memory more than any other. One person knows the order. One person knows which accounts always need an adjustment. The month that person is out, the close slips a week.
So this post is the fix. A practical, repeatable way to close the books every month, the actual order I’d run it in, a month-end close checklist to lean on, and what to write down so the close doesn’t live in one person’s head.

What “Closing the Books” Actually Means
Closing the books means finalizing all the accounting transactions for a period so the financial statements for that period are complete and won’t change. Once the books are closed, that month is locked. The revenue, expenses, assets, and liabilities for that period are settled, and the income statement gets zeroed out into retained earnings so the next period starts clean.
In practice, “the close” is whatever you run once the calendar flips: recording anything that hasn’t been entered yet, reconciling every account against an outside source of truth, booking the adjustments accrual accounting requires, then reviewing the output before anyone relies on it.
Most teams run a monthly close (sometimes a lighter “soft close” mid-year and a fuller “hard close” at year-end). That monthly rhythm is what keeps surprises small. Wait longer between closes and the guesswork just piles up.
Build a Close Calendar Before You Touch a Single Number
The biggest reason closes slip isn’t the accounting itself. It’s that the inputs aren’t ready. You can’t reconcile the bank until the statement posts. Payroll accruals wait on payroll running. Revenue can’t close until billing is done. APQC benchmarking of more than 2,300 organizations shows the median monthly close runs 6.4 calendar days, with the top 25% of companies finishing in 4.8 days or fewer and the bottom quartile taking more than 10 days. Most of that spread is not accounting skill - it’s calendar discipline and input readiness.
So before you reconcile anything, build a close calendar listing every task, who owns it, and which day of the close it’s due. A simple version:
- Day 0 (last business day): Cut-off communicated. No more invoices or expenses booked to the closing month.
- Day 1-2: Bank and credit card feeds imported. AP and AR finalized. Payroll posted.
- Day 3-4: Reconciliations completed. Accruals and adjusting entries booked.
- Day 5: Variance review, financial statements drafted.
- Day 6: Controller/owner review and sign-off. Period locked.
Your timeline might be tighter or looser. The exact days don’t matter much. What matters is that the calendar exists, it’s written down, and everyone touching the close knows their piece and their deadline. A close that lives only in someone’s head breaks the month they’re on PTO.
This is the kind of repeatable procedure worth turning into a documented finance SOP so it runs the same way every month regardless of who’s at the keyboard.
The Order of Operations: Close the Books Step by Step
Here’s the sequence I’d actually run. The order matters. Reconcile before all the transactions are in and you’ll just reconcile twice.
1. Lock the period and communicate cut-off
Tell the team the closing month is closed for new entries. Late invoices and expense reports for that period either get accrued or they wait. Without a hard cut-off, you’re aiming at a moving target.
2. Record all outstanding transactions
Make sure everything that economically belongs to the period is in the system:
- Accounts payable: all vendor bills received for the period entered and coded.
- Accounts receivable: all customer invoices for the period issued.
- Cash: every bank and credit card transaction imported.
- Payroll: the period’s payroll and related taxes posted.
- Expense reports: employee reimbursements submitted and recorded.
3. Reconcile every balance sheet account
This is the heart of the close. For each account, you’re tying the general ledger balance back to an independent source of truth. It is also one of the most direct fraud deterrents in any control environment: according to the ACFE’s 2024 Report to the Nations, account reconciliation is the detection mechanism in about 5% of occupational fraud cases, and organizations with active controls including management review and reconciliation experience substantially faster detection and lower losses than those relying on passive detection.
- Bank and credit card accounts → reconcile to the statement, dollar for dollar.
- Accounts receivable → tie to the AR aging.
- Accounts payable → tie to the AP aging.
- Prepaid expenses, fixed assets, accrued liabilities → tie to supporting schedules.
- Loans and credit lines → tie to the lender statement.
Anything that doesn’t tie out gets investigated now, not later. Unexplained reconciling items are how errors sneak into financial statements. Keep the supporting documentation attached so there’s a verifiable paper trail anyone can follow later without having to ask you.

4. Book accruals and adjusting entries
Accrual accounting means expenses and revenue land in the period they happened, not the period the cash actually moved. The usual month-end adjustments:
- Accrued expenses for work or services received but not yet invoiced (the trap that made me close twice).
- Prepaid amortization, spreading annual software, insurance, or rent payments across the months they cover.
- Depreciation on fixed assets.
- Deferred revenue recognition for the portion of prepaid customer contracts earned this period.
- Payroll accruals for days worked but not yet paid.
A standing list of recurring journal entries is worth its weight here. Most months, 80% of your adjustments are the same entries with new numbers.
5. Review the trial balance and variances
Pull the trial balance and the income statement, then compare against last month and against budget. You’re hunting for the tells numbers give off when something’s wrong:
- An expense account that’s suddenly double or zero.
- Revenue that doesn’t match what billing thinks it should be.
- A balance sheet account that didn’t move when it always moves.
Variance review is your last chance to catch a miscoded entry before it lands in the reports leadership reads.
6. Draft financial statements and get sign-off
Generate the income statement, balance sheet, and cash flow statement. Get a second set of eyes on it (controller, fractional CFO, or owner) before distribution. Then lock the period in your accounting software so nothing changes retroactively. That lock is what makes “closed” actually mean closed.
Common Reasons the Close Drags (and How to Fix Them)
After watching a lot of finance teams, the same culprits keep showing up:
- No cut-off discipline. Transactions keep trickling in for the closed month. Fix: a hard, communicated cut-off and an accrual policy for stragglers.
- Reconciliations done out of order. Reconcile before transactions are loaded and you’ll redo them. Fix: follow the order of operations.
- Tribal knowledge. Only one person knows the recurring entries and the quirks. Fix: document the close as a step-by-step procedure (more on this below).
- Manual data movement. Hand-keying bank transactions or rebuilding the same schedules in spreadsheets every single month. Fix: bank feeds, standing journal templates, and a fixed close calendar.
- No clear owner per task. “I thought you were doing the AR reconciliation.” Fix: one named owner per line on the close calendar.

Document the Close So It Survives Turnover
Here’s the part most teams skip until it hurts: writing the close down.
A monthly close is the textbook case for process documentation. It’s repeatable, it’s high-stakes, it’s done under deadline pressure, and it’s almost always stuck in one person’s head. When that person leaves (and my first finance hire did, four months in) the close walks out the door with them.
The hard part has always been that documenting the close is itself a slog. Nobody wants to screenshot 30 steps across QuickBooks, the bank portal, and three spreadsheets while also trying to actually close the month.
That’s the specific problem I built Glitter AI to solve. You run the close once the way you normally would, and Glitter captures every step (the clicks, the screens, the order) and turns it into a clean, shareable guide automatically. The next month, whoever runs the close, including a brand-new hire, follows the guide instead of interrogating the one person who knows it. If your team also runs the books in QuickBooks, the same approach captures those workflows too; we wrote up QuickBooks training for exactly that.
Document the close once and “closing the books” stops being a single point of failure.

A Reusable Monthly Close Checklist
Steal this and bend it to your chart of accounts:
- Communicate and enforce the period cut-off.
- Enter all AP bills for the period.
- Issue all AR invoices for the period.
- Import all bank and credit card transactions.
- Post payroll and payroll taxes.
- Record employee expense reports.
- Reconcile every bank and credit card account to its statement.
- Tie AR to the aging; tie AP to the aging.
- Reconcile prepaids, fixed assets, accruals, and loans to schedules.
- Book recurring and one-off adjusting journal entries.
- Review the trial balance and variances vs. prior month and budget.
- Draft the financial statements.
- Get controller/owner sign-off.
- Lock the period.
Run it the same way every month and the close stops being a fire drill. It turns into a routine you can hand to someone else.
Frequently Asked Questions
What does it mean to close the books?
Closing the books means finalizing all accounting transactions for a period so the financial statements are complete and won't change. The period gets locked, balances are reconciled, accruals are booked, and the income statement is rolled into retained earnings so the next period starts clean.
How do you close the books monthly?
Run a consistent sequence: enforce a cut-off, record all outstanding transactions, reconcile every balance sheet account to an external source, book accruals and adjusting entries, review the trial balance and variances, draft the financial statements, get sign-off, and lock the period.
How long should a monthly close take?
Most small and mid-size teams target a 5 to 7 business day close, though high-performing teams close in 3 to 5 days. The biggest lever isn't the speed of the accounting work itself; it's whether inputs (bank feeds, payroll, billing) are ready on a fixed close calendar.
What is the difference between a soft close and a hard close?
A soft close skips some detailed reconciliations and accruals to produce fast estimated numbers, often for interim months. A hard close completes all reconciliations, adjustments, and reviews to produce final, audit-ready statements, typically at quarter-end and year-end.
What is a close calendar?
A close calendar lists every task in the month-end close, its owner, and the day of the close it's due. It exists so the close isn't dependent on one person's memory and so dependencies (like a posted bank statement) are scheduled before the work that needs them.
What gets reconciled during the close?
Every balance sheet account: bank and credit card accounts to statements, AR to the aging, AP to the aging, prepaids and fixed assets and accrued liabilities to supporting schedules, and loans to lender statements. Anything that doesn't tie out is investigated before the period is locked.
What are adjusting journal entries in the close?
Adjusting entries move revenue and expenses into the period they economically belong to under accrual accounting. Common ones include accrued expenses, prepaid amortization, depreciation, deferred revenue recognition, and payroll accruals for days worked but not yet paid.
Why does the monthly close keep slipping?
Usually because of weak cut-off discipline, reconciliations done before transactions are loaded, tribal knowledge held by one person, manual data movement, or no clear owner per task. Fixing the close calendar and documenting the procedure resolves most of these.
Should you close the books in QuickBooks or Xero differently?
The accounting logic is the same: cut-off, record, reconcile, adjust, review, lock. The mechanics differ per tool (where the reconciliation screen lives, how you lock a period). Documenting the exact clicks for your software is what keeps the close consistent across people.
How do you make the close survive employee turnover?
Document it as a step-by-step procedure with named owners, recurring journal entry templates, and a fixed calendar. When the close is written down rather than memorized, a new hire can run it from the guide instead of interrogating the person who used to own it.
