Books months or years behind, and how catch-up actually works

It is more common than you think

Books fall behind for ordinary reasons. The business got busy, the person who was doing it left, the first year ran out of a spreadsheet that stopped scaling, or nobody was ever quite sure whose job it was.

The embarrassment people feel about it is the main thing that delays fixing it, and the delay is the expensive part. Every month that passes adds transactions to reconstruct, pushes documents further out of reach, and moves the problem closer to a deadline that will not move for you.

For what it is worth, nobody who does this work is surprised by a mess. We have opened files with four years unreconciled and files with a single quarter that somebody was mortified about. Neither reaction is useful and only one of them costs money.

Why history comes first

Starting a monthly service on top of unreconciled history does not work, and it is worth understanding why rather than taking it on trust.

Every month's numbers begin from the previous month's closing balances. If those are wrong, every month that follows inherits the error, the reports you are being sent are confidently incorrect, and the first real close surfaces two years of problems at once in the middle of a filing deadline.

Catch-up is therefore a separate engagement with its own scope, its own quote and its own finish line. The monthly service starts from the month after it lands, on balances that have been tied to something.

Why it is quoted on volume, not months

Eighteen months of a business doing forty transactions a month is a smaller job than four months of a business doing three thousand. The unit of work is the transaction, the reconciliation and the missing document, not the calendar.

Expect to be asked for transaction counts, the number of bank, card and processor accounts, and whether the receipts and invoices still exist, before anyone gives you a number. A quote offered without those three questions is a guess, and a guess on this work is either padded or about to be revised.

What we need from you

The list is short, and having it ready is most of the difference between a two-week job and a two-month one. Send it in one go rather than in fragments, because assembling it is the part only you can do.

• Bank and credit card statements for every account, for the whole period, as PDFs or CSVs rather than screenshots.
• Access to whatever accounting file exists, however bad it is. A broken file is more useful than no file.
• Merchant and payment processor reports, such as Stripe, PayPal or a marketplace's settlement statements.
• Loan and financing agreements, including anything from a founder or a related company.
• Payroll reports, if you have employees or contractors being paid through a service.
• Prior year tax returns, so opening balances can be tied to something that was already filed.
• A note of anything unusual you already know about, which saves us finding it in week three.

What actually happens during a catch-up

The work runs in a fixed order, because each step depends on the one before it. Knowing the order is useful when you are wondering why nobody has sent you a profit figure yet.

• Opening balances are established and tied to the last filed return or the last reconciled period.
• Every account is imported in full for the whole period, rather than sampled.
• Transactions are categorised, with a query list built for the ones that cannot be resolved from the record alone.
• Every bank, card and processor account is reconciled month by month to its statements.
• Inter-account transfers, owner contributions and drawings are separated from income and expenses, which is where most self-prepared books have gone wrong.
• The period is closed, financial statements are produced, and the query list comes back to you with the things only you can answer.

What the IRS expects you to have kept

Reconstruction is easier when the documents exist, and how long they should exist is a rule rather than a preference.

The general position is that records supporting an item on a return are kept until the period of limitations for that return runs out, which is ordinarily three years. It is six years if income that should have been reported was understated by more than 25%, and employment tax records are kept at least four years from the date the tax is due or paid, whichever is later.

The practical reading of that is simple. Three years is the floor, not the target, and the situations that extend it are exactly the situations where you will most want the paperwork.

Cash or accrual, and when you do not get to choose

Most small businesses can use the cash method, which records income when it is received and expenses when they are paid, and which is simpler to keep and easier to reconstruct after the fact.

The choice disappears above a size test. A taxpayer meets the gross receipts test, and can generally use the cash method, if average annual gross receipts for the three prior tax years are at or below an inflation-adjusted threshold, which was $31 million for tax years beginning in 2025. Very few businesses reading this are near it, and the ones that are usually know.

Accrual is still often the better basis to manage on, even where it is not required, because it puts revenue in the month it was earned rather than the month the money arrived. A catch-up is a natural moment to change basis if you are going to, since the history is being rebuilt anyway.

What a clean close gives you

At the end you have reconciled accounts, financial statements that mean something, and a tax return that can be prepared from evidence rather than assembled from memory and hope.

The less obvious benefit is that it makes everything after it cheap. Most of the cost of a late return is reconstruction, not preparation, and most of the cost of a first audit or a diligence request is the same work done under time pressure. Paying for it once, calmly, is the cheapest version there is.

The other thing it gives you is the ability to answer a question. How much did we make last quarter, what does a customer cost, can we afford this hire. None of those have answers on top of books that have not been closed, and running a business without them is more expensive than any bookkeeping quote.

Before you act on this

This is general information, not advice for your particular situation. Thresholds, forms and deadlines change, several of the rules described here differ by state and by the year in question, and the figures above were checked on the date at the top of this page rather than today. Confirm the current position before you rely on any of it.
