A month-end close checklist for bookkeepers, before the client report goes out
A monthly client report is only as good as the close underneath it. If the books are half-finished when you build the pack, the charts look confident and the numbers quietly mislead.
Most bookkeepers have a close routine in their head. The trouble is that a routine in your head changes depending on how busy the week is, and it is hard to hand to anyone else. Writing it down as a checklist makes the close repeatable, makes it easier to spot what was skipped, and gives you a clear line between "the books are done" and "now I can report on them."
Below is a practical month-end close checklist for bookkeepers working in QuickBooks Online or Xero. It is not exhaustive, and every practice will adjust it, but it covers the steps that most often decide whether a monthly report can be trusted.
1. Get the inputs in before you start
A close that starts with missing information turns into a close that gets reopened. Before touching the ledger, check that you have what you need from the client:
- Bank and card feeds connected and current to month end, with any broken feeds fixed or statements requested.
- Receipts and bills for the month, especially for larger or unusual spending.
- Sales information that does not flow in automatically, such as payment platform reports or cash takings.
- Payroll reports for the period, if payroll runs outside the accounting file.
- Answers to last month's open questions.
A short, consistent request sent at the same time each month tends to work better than ad hoc chasing. Clients learn the rhythm, and you get a clear date to start from.
2. Clear the uncategorised and suspense items
Every file collects items parked for later: uncategorised income and expenses, suspense or "ask my accountant" style accounts, unmatched bank lines. These are the most common reason a P&L looks wrong. Work through them before reconciling, and keep a short list of anything you genuinely cannot resolve so it becomes a question for the client rather than a guess.
3. Reconcile every bank, card and loan account
Reconcile each account to the statement balance at month end, not just to the feed. Feeds can duplicate, drop or delay transactions, and a reconciled statement balance is the check that catches it. Include accounts that are easy to forget:
- Credit cards and charge cards.
- Loan and finance accounts, so the balance sheet liability matches the lender's statement.
- Payment processor or clearing accounts, which should net down to what is genuinely in transit.
- Petty cash, if the client still uses it.
In QuickBooks Online, it is also worth checking that payments waiting to be deposited are not piling up. In Xero, check that nothing has been left unreconciled in the bank account screen for the period.
4. Review receivables and payables
Run aged receivables and aged payables as at month end and read them, rather than just exporting them. Look for:
- Invoices that were paid but not matched, which inflate receivables.
- Bills entered twice, once from a receipt and once from a feed.
- Old balances that need a conversation about write-off or collection.
- Customer or supplier credits sitting unapplied.
These reports often end up in the client pack, so any oddity here will be the first thing an engaged client asks about.
5. Post the month-end adjustments
Depending on the client and the level of service you offer, this may include accruals for costs incurred but not yet billed, prepayments for annual costs paid up front, depreciation, and payroll liabilities. Keep these consistent from month to month. A report that swings because an accrual was posted one month and forgotten the next will create commentary you then have to explain away.
6. Run a quick reasonableness review
Before you call the books closed, compare the month to the previous month and to the same month last year, if you have it. You are not writing commentary yet; you are looking for anything that does not make sense:
- Expense lines that jumped or vanished.
- Gross margin moving more than you would expect for the business.
- Balance sheet accounts with the wrong sign, such as a negative bank balance on an account that cannot go overdrawn.
- Sales tax or VAT balances that do not line up with the period's activity.
Anything odd either gets fixed or goes on the client question list. This step is the bridge between the close and the report: the movements you find here are often the ones worth explaining in your commentary.
7. Lock the period
Once you are satisfied, lock the month so later edits do not silently change numbers the client has already seen. QuickBooks Online has a close-the-books setting with a closing date, and Xero has lock dates. Note the date you locked and who did it. If something later needs changing, unlocking becomes a deliberate decision rather than an accident.
8. Only then, build the client report
With the books reconciled, reviewed and locked, the report becomes a presentation job rather than an investigation. Pull the P&L, balance sheet and the KPIs that matter for that client, add a trend view so the month sits in context, and write the commentary from what you found in the review step.
If report building still eats most of your month-end time, we wrote separately about how long a monthly client report pack should take and where the hours tend to go. And because the review step feeds your narrative, it is worth reading why commentary should stay bookkeeper-owned, even when software drafts the first version.
Making the checklist stick
A checklist only helps if it is used every month. A few habits make that easier:
- Keep one master version and a per-client copy for exceptions, such as a client with a loan, inventory or multiple currencies.
- Tick it off in the same place each month, whether that is your practice management tool, a spreadsheet or a shared document.
- Record the open questions alongside the checklist, so next month starts with them.
- Review the list each quarter and remove steps nobody actually does, or add the ones you keep remembering at the last minute.
The point is not paperwork for its own sake. It is being able to send a report and know that every number in it has been looked at.
Where ClosePack fits
ClosePack is in its founding pilot: it turns a QuickBooks Online or Xero export into a branded monthly client PDF with KPIs, trends and draft commentary you edit and own. It is early and deliberately narrow. If that sounds useful, have a look at the sample pack or request a founding spot.
