What Does a Bookkeeper Do Each Month? Reconciliation Is the Test

What does a bookkeeper do each month? A real one reconciles every bank, credit card, and loan account to its statement, ties payroll and loan balances to outside documents, and closes the month with a short list of questions answered. Categorizing a bank feed is not bookkeeping. It’s data entry, and the difference shows up the first time you try to make a decision with the numbers.

We run an accounting firm, and “we do your books” is the most common promise in this industry. It’s also the vaguest. Here’s what it should mean, and how to check in about two minutes whether yours means it.

What does a bookkeeper actually do each month?

Strip the job to its core and it’s three verbs: record, reconcile, close.

Recording is the part everyone sees. Transactions come in from the bank feed, get a category, and land on the profit and loss. Most software does 80% of this on rules now, which is why the price of “bookkeeping” has fallen and why a lot of what’s sold under that name stops here.

Reconciling is the part that makes the numbers true. Every account that has a statement gets matched to that statement, line by line, to the penny, every month. Checking, savings, each credit card, the line of credit, the equipment loan, the merchant processor. If a deposit is in the bank but not in the books, reconciliation finds it. If an expense is in the books twice, reconciliation finds that too. Nothing else does.

Closing is the decision that the month is done. Uncategorized is zero. Payroll in the ledger matches the payroll reports. Loan balances match the lender. Sales tax collected matches what was filed. The open questions went to the owner in one list and came back answered. Then the reports run, and nobody touches that month again without a reason.

What is the difference between bookkeeping and a monthly close?

Bookkeeping without a close gives you a profit and loss that’s probably close. A monthly close gives you one you can act on. That’s the whole difference, and it’s the difference between spending money on software and spending money on an accountant.

Here’s how it fails in practice. A bank feed pulls in a $4,000 loan payment and the rule calls it “Loan Expense.” The P&L now shows $4,000 of expense that is mostly principal. Do that twelve times and the business looks $30,000 less profitable than it is, the tax estimate is wrong, and the loan balance in the books never goes down. No reconciliation, no catch. Nobody lied. Nobody was lazy. The feed just did what feeds do.

Or the reverse: a customer pays by check, the check is deposited, and the invoice is never marked paid. Revenue is counted twice, once as the invoice and once as the deposit. The month looks great. It wasn’t.

Reconciliation catches both because the bank statement is the one document nobody in your business wrote.

The monthly checklist

If you want to know what you’re paying for, this is the list. In order:

1. Statements pulled for every account, the bank’s own PDF, not just the feed.
2. Transactions categorized by rule, with the rules written down so the same vendor lands in the same place every month.
3. Every account reconciled to its statement. Bank, cards, loans, merchant accounts, and the payroll clearing account.
4. Payroll tied to the payroll reports: gross wages, taxes, and fees split out, not one lump per pay date.
5. Loans tied to the lender’s statement, with the payment split between interest and principal.
6. Sales tax tied to the return that was filed.
7. One question list sent to the owner, ideally under ten items, answered in one sitting.
8. Close by the 10th of the following month, with the reports delivered the same day.

That last date matters. A month closed on the 10th gives you three weeks to act on it. A month closed on the 25th, or never, is history.

The one report to ask for

Here’s the two-minute test. Ask your bookkeeper for last month’s reconciliation report for each account. Every accounting platform produces one. It shows the statement ending balance, the book balance, and the difference, which should be zero, along with the date it was reconciled.

If the report exists and the difference is zero, your books are reconciled. If the report exists for checking but not for the credit cards or the loan, you know which accounts are being skipped. If there’s no report, or you get an explanation instead of a report, the books aren’t reconciled, and everything downstream is an estimate.

You don’t need to understand accounting to run this test. You need to ask one question and look for one number.

What it costs to skip it

Skipping reconciliation doesn’t save money. It moves the cost to a worse time.

An unreconciled year turns into a cleanup: the same reconciliation work, done twelve months at once, under a deadline, while the firm is at capacity. It turns into an extension, because the return can’t be built on numbers nobody trusts. And it turns into a guessed tax estimate, which means either an April surprise or a year of overpaying the IRS for the privilege of a refund.

We just finished four full-year restaurant cleanups in under ten hours of staff time before the September 15 deadline. That was possible because we ran them in the right order with software that reads the bank’s own statements. It was still a cleanup. Every one of those months could have been closed in the month it happened.

What a CFO does with this number

Reconciled books are the raw material for every decision a fractional CFO helps you make. Not one of these works without them:

• The cash forecast. A 13-week forecast starts from the reconciled bank balance. Start from an unreconciled one and every week after it is wrong by the same amount.
• The tax estimate. An estimate built on real year-to-date profit, not last year’s safe harbor, is usually the biggest cash decision of the quarter. It needs a real profit number.
• Pricing. Margin by service, labor as a percent of sales, job costing: all of them are ratios, and a ratio with a wrong numerator is worse than no ratio.

A CFO reading unreconciled books is a weather forecaster reading last week’s thermometer. The advice sounds fine. It just isn’t about your business.

Where we come in

We close every client’s books by the 10th, reconcile every account to its statement, and send the reconciliation report with the monthly package so you never have to ask for it. Questions go out once, in one list. Payroll is run in-house, so the payroll tie-out is part of the close rather than a phone call to a third party. And when the books are closed monthly, the tax return in March and the estimate in December are reports, not projects.

If you’ve never seen a reconciliation report from your current bookkeeper, run the two-minute test this week. If the answer is an explanation instead of a report, reach out. We’ll start with a two-hour diagnostic and tell you exactly where the books stand.

Frequently asked questions

What does a bookkeeper do each month?
Pulls statements, categorizes transactions, reconciles every bank, card, and loan account to its statement, ties payroll to the payroll reports, and closes the month with a short question list.

How can I tell if my bookkeeper is doing it right?
Ask for last month’s reconciliation report for each account; if there isn’t one, the books aren’t reconciled.

What is a monthly close?
The point each month when every account is reconciled, uncategorized is zero, and the numbers are final enough to make decisions on.
