What drives catch-up cost (it's not just time)
Transaction volume beats months behind
A business running 300 transactions a month costs two to three times more to catch up than one running 75, for the same number of months. Volume is the workload; the calendar just describes it. This is why 'how much for a year of catch-up?' can't be answered without seeing the file.
How many accounts need reconciling
Every bank account, credit card, loan, line of credit, and payment processor multiplies the reconciliation work. A single-checking-account business is a fundamentally smaller project than one with two banks, three cards, a loan, and Stripe.
Payroll and contractors
If payroll ran during the backlog period, every cycle has to tie out, gross, taxes, net, and contractor payments need W-9 documentation for 1099s that may already be late. Payroll typically adds 30–50% to a catch-up project.
The quality of what exists
There are two kinds of behind: nothing entered (clean slate, often easier), and things entered badly. Wrong categories, duplicate transactions, and creative journal entries must be found and unwound before correct work can start. Bad bookkeeping costs more to fix than no bookkeeping.
Entity type
S corps and partnerships need balance sheets that actually balance, owner basis tracked, and payroll formalities observed, expect 30–50% over a comparable sole proprietorship.
How catch-up pricing models work
- Fixed fee after diagnostic (what we do, and what to look for): the bookkeeper reviews your file, quotes one number in writing, and eats the overage if they scoped it wrong. Aligns incentives correctly.
- Hourly ($50–$150 depending on who): fine in theory, but you're buying an open-ended meter on a project whose size you can't judge. Get a cap in writing if you go this route.
- Per-month-behind flat rates: simple, but crude, they overcharge simple businesses and undercharge complex ones, and the provider knows which one you are.
Why the price is almost always worth paying
Catch-up work is rarely optional by the time you're pricing it. A tax deadline, a loan application, a state notice, or a buyer's due diligence is usually driving the urgency, and every one of those gets more expensive when the books stay broken. Your CPA charges 30–50% more to prepare a return from disorganized records, penalties compound monthly, and lenders simply decline files without financials. The backlog also doesn't age well: bank feeds expire, statements get harder to retrieve, and memories of what that $4,300 Home Depot charge was for evaporate. The same project costs more every quarter you wait.
How to keep your project at the low end
- Gather statements first, every account, every month of the gap. Statement-chasing is billable time you can do for free.
- Don't 'pre-clean' the file. DIY fixes on top of the mess usually add work. Freeze it and hand it over.
- Answer the mystery-transaction list fast, the back-and-forth on unidentified charges is where timelines stretch.
- Ask for the diagnostic before the quote, anyone quoting a full cleanup sight-unseen is guessing with your money.
- Bundle the go-forward, most firms (ours included) price the catch-up better when monthly service follows, because we're inheriting the file we cleaned.
What a good catch-up project delivers
Done right, you end with every transaction categorized, every account reconciled to statements, a balance sheet that balances, clean year-end totals your tax preparer can file from, and a written summary of what was fixed. If a quote doesn't include reconciliations, not just categorization, it isn't a cleanup; it's a categorization pass wearing a cleanup's price tag.
Frequently asked questions
How long does catch-up bookkeeping take?
Most projects run two to six weeks: a few days of setup and diagnostics, the bulk work, then a punch list of questions only you can answer. A hard tax deadline can compress that, tell your bookkeeper the real date on day one.
Can I file taxes while my books are still behind?
You can file an extension, which extends filing, not payment. A reasonable estimate of tax owed still needs paying by the original deadline, which is itself a reason to start the catch-up now: you can't estimate what you can't see.
Will you judge the state of my books?
No. Behind is the most common state small business books are in when owners finally seek help, it's why the service exists. The owners who should feel awkward are the ones who stay behind another year.
