How Much Does a Bookkeeping Cleanup Cost, and How Long Does It Take? (2026)

Last updated October 2026.

The short answer

A bookkeeping cleanup costs about $300 to $500 for one to three months behind, $500 to $1,500 for four to six months, $1,500 to $3,500 for seven to twelve months, and $3,500 to $8,000 or more past a year, per 2026 industry pricing guides, one entity, 50 to 150 transactions a month. It takes one to two weeks for a short clean backlog and four to eight weeks for six to twelve months. Messy books cost more than late books, and missing statements move the price more than months.

What is the difference between catch-up, cleanup, and a rebuild?

The difference is whether your records are late, wrong, or gone, and the price climbs at each step. Most quotes you will see online lump the three together, which is why the ranges look so wide.

Most real projects are a mix. If your books feel "messy" rather than "behind," assume foundation work, not catch-up, when you read a price range.

How much does a bookkeeping cleanup cost in 2026?

Published 2026 pricing guides from bookkeeping firms cluster around the same four bands, and the bands below assume one entity, statements available, and 50 to 150 transactions a month.

Firms that price per month of history behind publish a second version of the same math: about $150 to $300 per month for low-complexity books, $300 to $600 for medium, and $600 to $1,200 or more for high complexity (multiple entities, receivables or payables that need reconstruction, messy payroll). Multiply by your months behind and you get a sanity check on any quote. A medium-complexity business eight months behind lands at $2,400 to $4,800 on that math.

Hourly work, when a firm will not quote flat, runs about $40 to $90 an hour for production bookkeeping, $75 to $125 for a senior bookkeeper or cleanup specialist, and $125 to $200 or more for controller review. For scale, the Bureau of Labor Statistics puts the median wage of an employed bookkeeping clerk at $50,670 a year, or $24.36 an hour, as of May 2025. The gap between that wage and a $75 to $200 billing rate is review, software, and the judgment calls that a backlog is full of.

What actually drives the price?

Five things drive the price, and months behind is only the first one.

1. Account-months, not months. Every bank account, credit card, loan, and payment processor is its own reconciliation for every month in the backlog. Three accounts over nine months is 27 reconciliations. Six accounts over nine months is 54, for the same "nine months behind."
2. Transaction volume and fragmentation. 800 transactions through one bank feed can be easier than 250 split across Stripe, PayPal, Square, and three cards, because every processor needs its gross deposits matched to net payouts.
3. Condition of what is already there. A file that was never touched is cheaper than a file that was touched badly. Uncategorized bulk imports, duplicate entries from a broken feed, negative balances, and loans with no liability account each add hours, and the 2026 guides put entity complexity (S corporations, partnerships, multiple entities) at 30 to 50 percent more.
4. Missing statements. QuickBooks Online bank feeds typically pull about 90 days of history, and some banks allow up to 24 months. Anything older has to be downloaded from the bank and imported by hand, or requested from a closed account. Missing months are the single fastest way to turn a cleanup into a rebuild.
5. Deadline pressure. "Get it caught up" costs less than "deliver a lender-ready file by Friday." A hard deadline compresses review time, and firms price that.

If you carry inventory, the cost sits outside these bands almost every time. Inventory and cost of goods sold rebuilds are usually scoped as separate work, because they need counts and purchase records that a bank feed does not contain.

How long does a bookkeeping cleanup take?

A cleanup takes one to two weeks for a simple one-to-three-month backlog and four to eight weeks for six to twelve months at moderate volume, with multi-year rebuilds running four to six months, according to the 2026 timeline guides.

Two things stretch these more than anything on the provider's side. The first is your response time: every backlog has transactions only the owner can explain (a payment to an individual could be a contractor, a draw, or a loan repayment), and a client who answers in 24 hours keeps the project moving while a client who answers weekly adds weeks. The second is statements. Gathering every bank and card statement for the whole period before kickoff is the one thing you control that shortens the timeline.

An illustrative example: a $4M services business, eight months behind, 250 transactions a month across two bank accounts, two cards, and a payroll platform, with a chart of accounts that lumps cost of revenue into operating expenses. That is medium-to-high complexity. Expect a price in the $2,400 to $4,800 range on the per-month math, possibly higher for the chart of accounts rework, and a timeline of six to ten weeks: one week of diagnosis, one to two weeks fixing the structure, then the eight months processed oldest to newest at two to four business days each.

What should be finished when the cleanup is done?

A finished cleanup means every month in the backlog produces financials you would show a lender. Specifically:

1. Every bank, card, and loan account reconciles to its statement for every month, with zero unmatched items.
2. The balance sheet accounts are supported by something real: a loan statement, a payroll report, a fixed asset list, not a plug.
3. The P&L for each month reflects what happened in that month, with revenue and cost in the same period.
4. There is a documented opening balance for the first live month going forward.
5. You get a written summary of what was found and corrected, because the point is that it does not happen again.

If the deliverable is "the file is caught up" with no reconciliation reports and no summary, you bought catch-up, not a cleanup, and your CPA will find the difference before you do.

When is it cheaper to skip the cleanup and start fresh?

Starting fresh is cheaper when the old file is more than about two years stale and nothing in it needs to be defended. The test is whether anyone will ever ask for those periods.

If a lender, buyer, or investor will want three years of history, you need the history cleaned, and the price is what it is. If the old file is a sole proprietor's abandoned experiment and the business has since changed entities, it is often faster to set up a new file with correct opening balances from the bank and loan statements and let the old periods stay in a drawer. That decision has tax and legal implications, so make it with your CPA on the call, not after.

The one thing that is never cheaper is waiting. Backlogs grow, bank feeds age past their history window, statements from closed accounts get harder to pull, and the memory of what a $4,000 deposit was fades. Each quarter you wait adds account-months at full price and moves some of the catch-up into rebuild territory.

Where does Thryve fit?

Thryve Accounting & Advisory in McKinney, Texas does foundation work for founder-led businesses between $1M and $50M in revenue, mostly in food and beverage, construction and trades, e-commerce, and professional services. We scope every project after looking at the file, we reconcile every account for every month in the backlog, and we hand you a written summary and a clean opening balance, then move you to a monthly close so it stays clean.

Thryve is not the right fit if you are under about $1M with a single bank account and a short backlog; a solo bookkeeper will be cheaper and fast enough. Thryve also does not do tax. If part of your cleanup is amended returns or sorting out what you owe, that is your CPA's work, and we coordinate with them.

If you are not sure which of the three types you have, start with a QuickBooks health check, which tells you what shape the file is in before anyone quotes you. For the full foundation work scope, see QuickBooks cleanup. And if you are trying to decide what to spend on the finance function once the books are clean, how much should you actually spend on accounting and finance walks through the ranges.

FAQ

How much does it cost to clean up a year of QuickBooks?

A year of QuickBooks cleanup typically costs $1,500 to $3,500 for a single-entity business with statements available and 50 to 150 transactions a month, and $3,500 to $8,000 or more once statements are missing, payroll was posted inconsistently, or the prior year was never closed, based on 2026 industry pricing guides. The figure is an industry range, not a quote; two businesses the same number of months behind can land at very different prices depending on how many accounts need reconciling and how wrong the existing entries are.

Can I do the bookkeeping cleanup myself?

You can do the cleanup yourself when the backlog is under about three months, you have one or two accounts, and the existing entries are correct, because that is data entry and reconciliation rather than investigation. Past that, the risk is compounding existing errors and spending evenings on work that bills at $40 to $90 an hour, and anything with payroll, inventory, or a lender deadline is usually worth handing off. If you do it yourself, download every statement first and work oldest month to newest.

How long does it take to catch up 6 months of bookkeeping?

Catching up six months of bookkeeping takes two to four weeks when the file is clean and volume is moderate, and four to eight weeks when there are structural problems such as a misconfigured chart of accounts or unreconciled prior periods. The biggest variable is on your side: having every bank and card statement ready at kickoff and answering the provider's transaction questions within a day or two keeps the project on the short end of the range, while gathering documents as you go and answering weekly adds weeks.
