A Month-End Close Checklist for Growing Companies

Why the close takes so long

A slow month-end close is almost never caused by the accounting itself. It is caused by waiting: waiting for expense receipts, waiting for a bank statement, waiting for someone to confirm whether a project milestone was delivered. Every wait is a dependency that could have been resolved during the month rather than after it. The goal of a close checklist is to move work earlier and to make the remaining work strictly sequential.

Days -5 to 0: work done before the month ends

Chase outstanding expense claims with a hard cut-off communicated twice. Confirm which recurring invoices will be issued and to whom. Review the open purchase order list and flag anything received but not invoiced. Ask project owners to confirm milestone completion status. None of this requires the month to be over, and together it typically removes three to four days from the critical path.

Day 1: freeze and capture

Lock the prior period against new transactions. Anything arriving after the lock goes to the next period with an accrual if material. Without a lock, the close becomes a moving target and every report you produce is immediately stale.

Issue all remaining customer invoices on day one. Invoicing is the single activity where delay costs real money, because payment terms start from the invoice date.

Day 2: reconcile cash and receivables

Reconcile every bank and card account to the statement. Unreconciled items should be individually identified, not netted. Then age the receivables ledger and separate genuinely overdue invoices from disputes — they need different follow-up and mixing them produces useless collection reports.

Day 3: accruals, prepayments and payroll

Record accruals for goods and services received but not invoiced, using the flagged purchase order list from the pre-close work. Release the portion of prepayments that belongs to the period. Confirm payroll journals including employer contributions, bonuses and any leave provision movement.

Keep a standing accruals schedule rather than rebuilding it monthly. Most accruals repeat, and a schedule turns a discovery exercise into a review exercise.

Day 4: review, variance and reporting

Produce the profit and loss, balance sheet and cash flow, then run a variance review against both budget and the prior month. Investigate any line that moves more than a set threshold — a fixed percentage plus a minimum absolute value works better than percentage alone, which flags trivial movements on small accounts.

The output of the close is not the statements. It is a short commentary explaining what changed and why, written for the people who make decisions. Statements without commentary get filed unread.

Controls worth having even in a small finance team

Segregation of duties is difficult with two people, but three controls are achievable at any size. Payments above a threshold require a second approver. Bank reconciliations are reviewed by someone who did not prepare them. New supplier bank details are confirmed by a call to a known number, never by replying to the email that requested the change — this last one prevents the most common and most expensive fraud affecting small companies.

What to automate first

Automate in the order of frequency multiplied by error rate. Bank feed imports come first, then recurring invoices, then expense capture with receipt scanning, then approval routing. Automating report formatting is satisfying but usually saves the least time.

Track the close itself

Record two metrics every month: total days to close, and the number of post-close adjustments. Days falling while adjustments rise means you are closing fast by closing wrong. Both trending down over a quarter is the signal that the process is genuinely improving.

Realistic targets

A company under fifty people with clean systems should close in four to five working days. Under three days generally requires either very simple operations or substantial automation. Over ten days almost always indicates a data-collection problem rather than an accounting one — look at where the waiting happens before adding headcount.
