The Month-End Close Checklist for Small Businesses

Closing your books at the end of each month is the single habit that turns tax season from a panic into a formality. You catch errors while the transactions are still fresh, you always know where your business stands, and by December the year is already done twelve times over. Here is a checklist you can run in under an hour once it becomes routine.

The checklist

• Reconcile every bank and credit card account against its statement.
• Categorize anything still sitting in "uncategorized."
• Match income to invoices and enter any vendor bills.
• Review unpaid invoices (what customers owe you).
• Review what you owe others and when it is due.
• Look over your profit and loss and your balance sheet.
• Move money into a separate account for taxes.
• Back up or export your records.

Reconcile first

Reconciliation is the step that actually catches mistakes, so do it first. Match every line on the statement to your books, dollar for dollar. Glancing at the ending balance and deciding it "looks about right" is not reconciling, and it is exactly how duplicate or missing transactions slip through. If the process is new to you, our guide to bank reconciliation walks through it.

Clear the uncategorized pile

Every transaction needs a home. Letting things sit in "uncategorized" or "ask my accountant" is how a clean October becomes an unrecognizable December. Handle them monthly while you still remember what that 40 dollar charge was for.

Read the two reports that matter

Once the data is clean, glance at your profit and loss and your balance sheet. You are not auditing, you are sanity checking: does income look right for the month, are there expenses that seem off, do the balances move the way you would expect. A monthly read makes a strange number obvious while it is still easy to fix.

Set aside the tax money

If you are self-employed, the close is also when you move tax money out of reach. Income tax plus the 15.3 percent self-employment tax adds up fast, and quarterly estimates are due if you expect to owe 1,000 dollars or more for the year. Setting it aside monthly is far less painful than scrambling four times a year. See quarterly estimated taxes for the schedule.

How this connects to year-end

A monthly close is most of a year-end checklist already done. When the books have been reconciled and categorized every month, the year-end version is mostly review and a couple of annual items, not a from-scratch rebuild.

How Vuuv helps

Vuuv keeps the close short by importing transactions from your connected accounts and categorizing them as they arrive, so most of the month is handled before you sit down. Its reports give you the profit and loss and balance sheet on demand, and a running view of unpaid invoices, so the monthly review is a few minutes of looking rather than a day of assembling.
