What a Finished Month of Bookkeeping Should Show You

TL;DR: A month of bookkeeping is finished when four things are true: every account is reconciled to its statement, nothing is left uncategorized, transfers and owner money are where they belong, and anything unresolved is written down as an open item. If you can't see all four, you can't tell whether the month is done, no matter who did the work. Ask for that status from your bookkeeper. Prosper shows it as the state of your books. TidyMonth delivers it with every close, reviewed by a bookkeeper.

You pay someone for bookkeeping. Or you do it yourself, some weekends. Either way, the question is the same: is last month actually finished?

The reports came. The bank balance seems right. But you've had reports before that turned out to be built on half-categorized months, and you've reconciled accounts yourself and later found the categories were wrong. "Done" turns out to be a feeling more often than a fact.

Most owners who work with a bookkeeping professional are happy with them. In OnPay's 2025 survey of more than 1,000 business leaders, over 90% of those working with an accounting professional rated the relationship as satisfied or very satisfied. The problem usually isn't the person. It's that nobody defined what finished looks like, so nobody can check.

Here's the definition.

The four things a finished month shows

1. Every account reconciled, with a date. Checking, savings, every card, every payment processor, each matched to its statement balance as of the last day of the month. Not "the main account." All of them. If one card wasn't reconciled, the month isn't done, because the balance sheet is built on that card's balance.

2. Nothing uncategorized. No transactions sitting in "uncategorized," "ask my accountant," or "other." Every line has landed somewhere, or it's on the open items list with a reason.

3. Transfers and owner money in the right place. Transfers between your accounts matched on both sides. Card payments recorded as transfers, not expenses. Personal spending in owner's draw. Owner money in as contributions, not revenue. These are the four errors that reconcile perfectly and still make the reports wrong. See Your Accounts Reconcile. Your Profit and Loss Still Looks Wrong.

4. A written list of what's still open. The deposit nobody could identify. The purchase waiting on a receipt. The question for the CPA. A finished month isn't one with zero open items. It's one where the open items are visible instead of quietly guessed at.

When all four are true, the reports mean something. The profit and loss reflects real revenue and real expenses. The balance sheet reflects real cash and real obligations. And you know exactly what's uncertain.

What to ask for from a bookkeeper

If someone else does your books, ask them for a monthly status that shows the four things directly. It can be a short email. It should include:

• Which accounts were reconciled and through what date.
• Whether anything is uncategorized, and if so, why.
• The questions they need you to answer, with the transaction, the amount, and the date.
• The open items carried into next month.
• Who reviewed the month and when.

If you're getting reports without this, you're getting output without evidence. A good bookkeeper won't mind the ask. It's the same checklist they use themselves.

How to check your own month in any bookkeeping software

Step 1: Check the reconciliation dates. Most software shows, for each account, the last date it was reconciled. Every account should show the last day of the month you're checking. Any account that doesn't is your first job.

Step 2: Search for uncategorized. Filter transactions by category and look at the junk drawer accounts. Empty them or move each item to the open list.

Step 3: Run the classification checks. Revenue against customer deposits. Card payments in expense categories. Round-number deposits with no invoice. Personal items in business categories. Ten minutes on one month catches most of it.

Step 4: Write the open items down. In a note, in the memo field, wherever you'll see it next month. Date, amount, merchant, what you know, what you need.

Step 5: Save the reports. Profit and loss and balance sheet for the month, exported and dated. When your CPA asks in February what March looked like, this is the answer.

Illustrative example. An IT services owner paid for bookkeeping and received a profit and loss each month. When she asked for the reconciliation status, it turned out that two of her three accounts had been reconciled through August and the third, a card used for cloud services, hadn't been reconciled since April. Four months of that card's charges were in the books but unverified. The reports had looked fine. They were built on an unreconciled account. Once she asked for the four things every month, she could see the status instead of trusting the reports.

How this works in Prosper

Prosper is the platform TidyMonth uses for the monthly work, and you can use it yourself with your CPA.

In Prosper, the four things aren't a checklist you run at month end. They're the state of your books, visible all the time.

Each connected account shows whether it's reconciled and through what date. Transactions that need a decision sit in the decision inbox until you've answered them, so "nothing uncategorized" is the same as "no decisions waiting." Transfers are shown as pairs and confirmed as pairs, so the classification errors that reconcile silently in a feed become questions instead. Open questions stay attached to their transactions, so the open items list writes itself.

The status Prosper shows is either all clear or needs review. If Prosper can't verify something, it flags it instead of telling you everything is fine. When you prepare the CPA packet, that status comes with it: what was reconciled, what was decided, what's still open.

Prosper doesn't certify the month. It makes the state of the month visible so you, or a bookkeeper, or your CPA can see whether it's done.

If you'd rather hand it off: TidyMonth by Prosper

If you'd rather someone else got the month to that state and showed you the status, that's what a TidyMonth close is.

Start with a free Books Check. No card required, and nothing in your accounts is changed while we look. The results show which month your books are reliable through, what needs attention, and what couldn't be verified from the records available.

If your business fits, monthly bookkeeping is $199 per month, with catch-up scoped and priced before checkout. Each month, TidyMonth handles the agreed work in Prosper and a bookkeeper reviews the close. You receive the accounts reconciled, the reports, the questions that need your answer, and the open items, with the reviewer's sign-off and the completion date. You answer the business questions. You can always see which month is finished and what's still open.

If the first close isn't worth it, your first $199 is refunded in full. Cancel in one click. Export your books any time.

What your CPA still decides

A finished month is complete, reconciled, and honest about its open items. It isn't a set of financial statements certified as correct, and it doesn't settle any tax treatment. Reconciled balances and a reviewed close don't guarantee the statements are right in every respect. They make the month traceable, so your CPA can review it and decide.
