The quick answer
Catch-up bookkeeping — bringing months or years of unkept books up to date — typically costs Canadian small businesses $500 to $25,000 depending on how far behind, how messy, and how much source documentation still exists.
Rough bands:
- 3 to 6 months behind: $500 to $2,000
- 6 to 12 months behind: $1,500 to $5,000
- 1 to 2 years behind: $3,000 to $10,000
- 3+ years behind: $5,000 to $25,000+
Cleanup is almost always done at a flat-fee or fixed-quote rate, not hourly — because nobody wants the meter running on an unknown-size job. The price is shaped by transaction volume per month, whether you have source documents (bank statements, receipts, invoices), what software you are using, and what industry you are in.
This guide breaks down what catch-up actually is, what makes it cost more, and what you get from doing it.
Catch-up vs cleanup vs reconstruction
These terms get used interchangeably, but they describe three different scopes:
Catch-up bookkeeping. You stopped doing books a few months ago, but you have bank statements, credit card statements, and most of your receipts. Someone needs to enter, categorise, and reconcile everything that happened in the gap. Most common scenario.
Cleanup bookkeeping. You have books, but they are wrong. Wrong categories, unmatched reconciliations, miscoded transactions, missing journal entries. Someone needs to audit and fix.
Reconstruction. No books, partial records, and unclear history. Someone needs to rebuild from bank feeds, statements, and whatever paper survives. Highest cost, longest timeline.
Most "catch-up" projects are actually a mix of all three. A good bookkeeper will tell you which during the quote.
The four factors that drive catch-up cost
1. How far behind you are
Each month of backlog adds work. Going from 3 months behind to 6 months behind roughly doubles the project. Going from 1 year to 3 years adds CRA risk (penalties, interest, possible audit triggers) on top of the bookkeeping work.
2. Transaction volume per month
A consulting business with 30 transactions a month is fast to catch up. An ecommerce store doing 300 orders a month plus Stripe payouts plus Shopify fees plus Amazon settlements is dramatically more work. Most bookkeepers price by monthly transaction brackets.
3. State of source documents
Catch-up is much cheaper when you have:
- Downloaded bank statements (PDF or CSV) for the whole period
- Credit card statements
- Receipts (digital or paper) for major expenses
- Invoices issued (in software or PDF)
- Payroll records (if you ran payroll)
It is much more expensive when:
- Bank login is lost or accounts are closed
- Receipts are in a shoebox or a phone photo gallery
- Sales records exist only in Shopify, Stripe, or Square exports that have not been downloaded
- Payroll was paid via e-transfer with no records
If you have no documentation at all, you are in reconstruction territory and costs jump.
4. What CRA filings were missed
If you also missed GST/HST returns, T4 slips, T2 corporate tax, or PD7A payroll remittances during the gap, the bookkeeping work has tax-filing work bolted on. Each missed filing adds its own preparation and adds CRA interest and penalty exposure.
CRA late penalties stack — for payroll source deductions, 3% for 1 to 3 days late, rising to 10% at 8+ days late. For corporate tax, 5% of balance owing plus 1% per month up to 12 months. These are not bookkeeping fees, but they show up in the same bill.
What you actually get from catching up
Three things, in order of immediate value:
1. Stops the bleeding. Every additional month you delay grows interest and penalty exposure on missed CRA filings. Catching up now stops the meter.
2. Unlocks deductions you are owed. Most behind-books owners are paying more tax than they should be. Missed Input Tax Credits on GST/HST, undeducted business expenses, missed capital cost allowance — a clean catch-up often saves more in recovered deductions than the catch-up itself costs.
3. Opens doors. Clean books are required for:
- Bank or alternative lender financing
- Selling your business
- Bringing on investors
- Hiring (for payroll setup)
- Sleeping well at year-end
If you are about to do any of those, catch-up is a prerequisite, not a nice-to-have.
How catch-up actually works (the workflow)
A typical catch-up project at Fluent Books:
- Discovery call — we look at scope: months behind, software, documents you have.
- Fixed quote — a flat fee for the whole catch-up, broken into milestones if multi-month.
- Document collection — you send bank statements, credit card statements, receipts, and payroll records.
- Software setup or fix — if you have no QuickBooks Online or Xero file, we set one up. If yours is broken, we restructure the chart of accounts.
- Historical entry and reconciliation — month by month, transactions entered, accounts reconciled.
- CRA filing prep — any missed GST/HST, T4, T2, or PD7A returns are prepared.
- Handoff — you get clean books, current financial statements, and either a monthly plan moving forward or a clean handoff back to your in-house process.
A 12-month catch-up for a typical service business runs 2 to 4 weeks. A 3-year catch-up for an ecommerce store can take 8 to 12 weeks.
The hidden cost of not catching up
If you keep putting it off, three things keep getting worse:
- CRA interest and penalties compound. Daily compound interest on unpaid GST/HST, payroll, and corporate tax. Penalties on top.
- Deductions get harder to recover. ITCs older than four years become much harder to claim back. Expenses without receipts get rejected.
- The catch-up itself gets more expensive. Three years of catch-up is more than three times one year of catch-up — there is more reconstruction, more guesswork, and less software-aided automation possible.
Every month you wait, the math gets worse.
What does catch-up cost at Fluent Books?
Our bookkeeping cleanup service is custom-quoted based on a free initial review. We look at the months involved, your software (or lack of it), the state of your source documents, and any CRA filings you have missed. You get a fixed flat-fee quote back within 48 hours, no obligation to proceed.
For ongoing monthly bookkeeping after catch-up, see our pricing — most clients move to the Essentials or Growth tier once they are current.
Frequently asked questions
Can I just keep DIY and skip catch-up?
Technically yes — but you will pay for it at year-end when your accountant has to do bookkeeping at accountant rates, or when CRA notices the gap. The cheaper path is almost always catch-up now.
How long does catch-up bookkeeping take?
Most catch-up projects take 2 to 8 weeks depending on size. Larger reconstructions can take 3 months. Your bookkeeper should give you a target timeline as part of the fixed quote.
Will catch-up trigger a CRA audit?
Filing missed returns does not automatically trigger an audit. CRA expects late filings to be cured, and a voluntary catch-up is generally better received than waiting for them to notice. For sensitive situations involving years of missed corporate tax, the CRA Voluntary Disclosures Program may be relevant — your bookkeeper or a CPA can advise.
Do I need to do catch-up before I can hire a monthly bookkeeper?
Yes — most bookkeepers will not take you on monthly until your books are current. The cleanup or catch-up fee is typically a one-time payment at the start of the engagement.
Is catch-up bookkeeping tax-deductible?
Yes. Catch-up bookkeeping and related accounting fees are deductible business expenses on your T2125 (sole proprietor) or T2 (corporation) return.
