Key points
- Close means the month's records are checked and then left alone
- A short routine beats a long annual clean-up
- A written summary helps you spot changes early
Month-end close sounds formal, but it is a plain idea: at the end of each month you check the records, fix what is wrong and then stop changing that month.
This is general information about record keeping, not financial or tax advice.
What gets checked
The checks are the same every month, which is what makes them quick.
- Every bank and card account agrees with its statement
- Bills and invoices dated in the month are entered
- Receipts are attached or filed
- Payroll for the month is entered and agrees with the reports
- Anything unusual has a note beside it
Why locking the month matters
Once a month is checked, changes to it should be rare and deliberate. Many accounting programs let you set a lock date. A locked month stops a late edit from quietly changing figures someone has already used.
A summary you can read
The end product is a short note: what was done, what changed and what is outstanding. It does not need charts. It needs to be clear enough that you notice when something looks wrong.
How long it takes
For a small business with steady activity, a close done every month is much quicker than a year of backlog done at once. The time you save is in not having to remember what a payment was for.
When it slips
If a month has been missed, start with the oldest unchecked month and work forward. Catch-up work goes faster in blocks than in a scatter.
