A month-end close checklist you can actually run

Every close checklist you can find online was written for a finance department: a controller, a staff accountant, someone in accounts payable. If you run a five-person company, the person closing the books is you, or one bookkeeper who also answers the phone. The checklist has to survive a month where two other things caught fire.

What follows is the short version, in the order the work has to happen. The sequence matters more than the length.

Pick a close date and defend it

The date you choose matters less than whether you hold it. Pick a working day — the tenth, the fifteenth, whatever fits your bank and payroll timing — and treat it as the day the month is finished, not the day you start looking at it.

That needs a cut-off. State a time after which nothing else posts to the closed month. A vendor bill arriving on the twelfth for work done in June gets accrued into June if it is material and booked in July if it is not. What it does not do is reopen a month you have reported on — that is how you end up with three versions of the same profit and loss statement and no idea which one you sent the bank.

Reconcile cash before you look at anything else

Every other number depends on this one. Reconciled means each line is matched to a real statement, the ending balance agrees to the penny, and nothing is sitting uncleared since March. An uncleared check from eight months ago is not a reconciling item, it is a question.

Payment processors need their own pass. The deposit that lands in your bank is net — fees taken out, refunds netted off, sometimes a reserve held back — and it arrives days after the sale. Book that deposit as revenue and you have understated both your sales and your costs, and your books will never agree with what the processor reports at year end.

Pull one payout report per processor per month and record the pieces separately: gross sales, refunds, chargebacks, processing fees, anything held back, and the net that actually moved. It takes ten minutes a month, and it is the most common thing we find wrong in a set of books we inherit.

Bring in what happened but has not moved money yet

• Payroll earned in the month but paid in the next one, taken from the provider's report rather than the bank debit — along with the employer taxes that go with it.
• Bills that arrived after month end for work performed inside it.
• Money you have taken for work not yet delivered, which is a liability rather than a sale.
• Work you have delivered but not yet invoiced, which is a sale even though nothing has moved.
• Annual prepayments — insurance, software, professional fees — spread across the months they actually cover.

Prepaids are where small companies lose an evening. Set a materiality floor, write it down, and hold to it: below the number, expense it when paid and move on. Amortizing a four-hundred-dollar subscription over twelve months is not accuracy, it is a hobby.

The balance sheet is the actual test

Everyone reviews the profit and loss, because it is the interesting part. It is also the easy part. If the balance sheet is wrong, the profit figure is wrong in a way you cannot see from the profit figure itself.

Go down it line by line and ask what supports each number. Cash agrees to the statements. Receivables agree to the aging report. The loan balance agrees to the lender's statement, with the month's payment split correctly between interest and principal. Anything sitting in undeposited funds, in opening balance equity, or in an account named after the phrase you use when you do not know where something goes, gets cleared or explained before you file the month.

Owner activity belongs here too: personal spending on the company card, transfers that were really draws, money you put in to cover a payroll. If a balance is owed in either direction, you should be able to say what it is made of.

Two comparisons before you send anything

Put this month next to last month, and next to the same month a year ago or your budget if you keep one. Set a threshold in dollars rather than percentages — on small numbers a percentage swing tells you nothing — and explain every line that moves more than it.

Most of what you find will be a coding error, caught before it reached a report. The rest is the genuinely useful part of the close: a variance you cannot explain is something happening in the business that you did not know about.

Then read it like an outsider

Close the software and answer three questions from the statements alone.

• Did the business make money this month, and does the movement in cash agree with that answer? Where it does not, the gap is timing — and timing has a name: receivables, inventory, a tax payment, a loan repayment.
• Who owes us money that is old enough to chase this week rather than next quarter?
• What is committed for next month that these numbers do not show yet — a hire, a renewal, a quarterly tax payment?

Write it down, with names on it

A close that lives in one person's head is not a process, it is a dependency. The checklist fits on a page: each task, who does it, which working day it normally lands on, and where the supporting file gets saved. The first month that feels like bureaucracy. The second it takes half as long, because nobody is trying to remember what they did last time.

And when the month gets away from you

Some months you will not have the time. Triage honestly rather than stopping wherever you run out of evening. Cash reconciliation and payroll are never optional — those are the numbers other people rely on, and the ones that compound quietly when wrong. Prepaid amortization and immaterial accruals can wait a month and be caught up, provided you note that you did.

What you should not do is skip the reconciliation to hit the promised date. Then you have a report that is on time and wrong, which is worse than one that is late and right, because you will act on it.
