A month-end bookkeeping checklist that won't eat your Sunday

Month-end close is the one bookkeeping job that turns reasonable people into procrastinators. It sits on the calendar like a dentist appointment, and when it finally happens it takes twice as long because the books have had three weeks to drift. The fix is not willpower. It is a checklist short enough to actually run. This one has three passes and takes about an hour when the books are current.

Pass one: make the numbers match

• Reconcile the bank account. Open the statement, tick every transaction against your books, and chase anything that appears on one side and not the other.
• Deal with unmatched transactions now. The coffee you bought for a client meeting is either a business expense or it isn't — deciding takes ten seconds today and ten minutes of archaeology next quarter.
• Record cash. Petty cash, the cash sale that never made it into the system, the owner's draw. Cash is where books quietly rot.

Pass two: check the obvious

• Every job you delivered this month — invoiced? The unsent invoice is revenue you earned and forgot to ask for.
• Every bill you received — entered, with its due date? Missed due dates are the fastest way to burn supplier goodwill.
• Payments received — applied to the right invoice? A payment sitting as an unapplied credit looks tidy to nobody, and confuses the client when their statement shows a balance you both know was paid.
• Payroll and taxes — do the withheld amounts look right? Wrong payroll numbers are not a next-month problem.

Pass three: close it and keep the evidence

• Pull a profit-and-loss and a balance sheet and actually look at them. You are not auditing; you are checking that nothing is absurd. Rent missing from the P&L is absurd.
• Note the tax figures — what you collected, what you owe — somewhere you will find them again at tax time.
• Close the period and export a copy. Months you cannot accidentally edit are months you do not have to re-explain.

How long should this take?

About an hour, once the books are current. If it regularly takes you a weekend, the books are behind and no checklist will fix that — the backlog will. Two options: set aside an hour every Friday to keep the backlog at zero, or hand the whole thing to someone whose job it is. Our bookkeeping service does exactly this inside Spheyas — transaction categorization, bank reconciliation and monthly reports, delivered every month.

And when you are deciding how your books should treat money in the first place, the question is usually cash basis or accrual — worth five minutes before your accountant asks you the same thing.
