Catch up bookkeeping pricing works best as a fixed project fee built from the client's statements: count the months behind, the accounts and the lines per month, estimate hours, then add a charge for records the client may not find. Quote it per month behind when the backlog is uniform, and take a deposit before any work begins.
Per-month or per-project catch up bookkeeping pricing?
Per-month catch up pricing charges a set amount for each month behind; per-project pricing quotes one total for the whole backlog. A per-month rate suits a backlog where every month looks alike. A project fee suits a backlog with uneven months, extra accounts, or a messy start that a flat rate would underprice.
A per-month rate has real advantages. The client can see exactly how the total was reached. If they find three more months they forgot, the price extends without a fresh negotiation. And you can bill as months are finished rather than at the end.
Its weakness is that months are rarely equal. The month a client opened a second account, the month they switched card processors, and the month a loan was funded can each take three times as long as a quiet one. A flat rate per month either overprices the quiet months or loses money on the busy ones.
A project fee absorbs that unevenness. It also lets you price the parts of a catch up that do not belong to any one month: setting up the chart of accounts, getting the opening balance right, and the final review before handing over. The client sees one number and one finish date.
A blend often works. Quote a project fee for the known backlog, then state a per-month rate for any extra months that turn up later. That keeps the main quote firm and the surprises priced.
Estimating catch up hours from the client's statements
Catch up hours are estimated from the statements themselves: the number of months behind, the accounts in each month, and the transaction lines per account. Ask for every statement before you quote, or at least a busy month and a quiet month for each account, so the estimate rests on real counts rather than the owner's memory.
Work through the backlog in this order:
- List every account. Checking, savings, each credit card, any loan, any payment processor. Owners forget accounts more often than they forget months.
- Count lines per account per month. A rough count from two sample months per account is enough to estimate.
- Set minutes per line. Use your own logged times. Clean card statements with repeat vendors go quickly; checking accounts full of transfers and cash deposits go slowly.
- Add fixed time per account per month. Reconciling each statement takes time regardless of how many lines it has.
- Add one-time work. Chart of accounts, opening balances, a review pass and the handover.
Volume is the biggest driver, and the same logic shapes ongoing fees; pricing bookkeeping by transaction volume shows how line counts become tiers for monthly work.
Entry time is the part that most depends on your tools. If months of PDF statements have to be typed in, entry dominates the hours. Converting the whole backlog in one batch with AutoBankConvert, with a balance check on each statement, moves most of the time to categorizing and review, which is where your judgment is needed anyway.
A worked quote for a client nine months behind
The figures below are an example, not a benchmark. The client is a small service business with one checking account and one credit card, nine months behind.
| Item | Checking | Credit card | Total |
|---|---|---|---|
| Months behind | 9 | 9 | |
| Lines per month (sample average) | 80 | 45 | |
| Total lines | 720 | 405 | 1,125 |
| Minutes per line (logged average) | 1.2 | 0.8 | |
| Line hours | 14.4 | 5.4 | 19.8 |
| Reconcile, per month | 0.25 h | 0.25 h | 4.5 |
| One-time setup and opening balances | 3.0 | ||
| Final review and handover | 2.5 | ||
| Estimated hours | 29.8 | ||
| Hourly target | $80 | ||
| Base fee | $2,384 | ||
| Missing records allowance (15%) | $358 | ||
| Project fee quoted | $2,750 |
The quote rounds up from $2,742 to $2,750. Each month in this backlog averages about $305, which also gives you a fair per-month rate for any extra months the client finds.
Pricing the risk of missing records in a catch up job
Missing records are the largest risk in catch up work, and the price should carry it openly. Add an allowance, often a percentage of the base fee, for statements that must be requested from the bank, receipts that never existed, and transactions only the owner can explain. State what the allowance covers so it does not read as padding.
The risk takes several forms:
- Missing statements. The client has no PDFs and cannot log in to an old account. Requesting statements from a bank takes time and sometimes costs the client a fee.
- Unexplained lines. Cash withdrawals, transfers to personal accounts and deposits with no memo all need the owner's answer.
- Closed accounts. An account closed during the backlog still needs its months reconstructed.
- A wrong starting point. If prior books exist but the balances do not match the bank, the first month carries extra work to find the gap.
Price the known risk inside the allowance and the unknown risk outside it. A sentence in the quote such as "if more than two months of statements cannot be obtained, we will quote reconstruction work separately" protects you without inflating the main price. Clients accept a stated limit far more easily than a surprise invoice.
The work you do on a backlog may also mean someone other than you sees years of a client's bank activity. If a catch up job goes to a subcontractor or a new hire, decide in advance what checks and access limits apply; background checks for bookkeeping staff covers what to check and how access should grow over time.
A catch up deposit before the first backlog month is touched
A catch up deposit is a share of the project fee paid before any backlog month is touched. It confirms the client is serious, pays for the setup hours that come first, and protects you if the client disappears halfway through. A third to a half of the fee is a workable size for it.
A clear payment schedule might look like this, using the example fee above:
- Deposit on signing: $1,100, paid before the first statement is converted.
- Midpoint payment: $825, due when months one to five are reconciled.
- Final payment: $825, due on delivery of the finished books, before the handover file is released.
Tie each payment to something the client can see finished. Releasing the final books on payment is normal for project work and gives the last invoice real weight.
Watch for one pattern in particular. Clients far behind are sometimes behind because cash is tight. A client who balks at any deposit may struggle with the later payments too, and that is better learned before the work than after it.
How does catch up pricing fit with a new monthly fee?
Catch up pricing and a new monthly fee should be quoted together but kept as separate lines. The catch up is a one-time project that ends; the monthly fee starts with the first current month. Mixing them into one blended number hides what each costs and makes the monthly fee look higher than it will be.
Set the order clearly in the quote. The current month usually starts on the normal monthly fee as soon as the engagement begins, even while the backlog is still being worked. That stops the backlog from growing while you clear it. The catch up project then runs alongside until the books are current.
A few points to settle:
- Which month does the monthly fee start on? Name it.
- Does the catch up cover the current month? It should not; the monthly fee does.
- What happens if the catch up uncovers more work? Point to the per-month rate for extra months.
- Is there a discount for committing to monthly work? If so, apply it to the project fee with a stated condition, not to the monthly fee, so the ongoing price stays honest.
When a catch up quote should be refused or split into phases
Some backlogs are too uncertain for a single fixed quote. When records are mostly missing, the client cannot say how many accounts existed, or prior books are wrong in ways you cannot measure yet, split the work into phases, or decline it. A fixed price on an unknown scope turns your hours into the client's insurance policy.
Signs that a phased quote is safer:
- More than a quarter of the statements cannot be produced.
- The owner mixed personal and business spending across several accounts.
- An earlier bookkeeper left books that do not match the bank, and nobody knows since when.
- There is a deadline, such as a lender or a tax filing, that will force rushed work.
Phase one can be a paid diagnostic: gather what exists, convert and balance what can be balanced, and list what is missing. That diagnostic gives a real basis for phase two. The approach is close to how cleanup work is priced, and bookkeeping cleanup pricing after a diagnostic walks through it for books that exist but are wrong.
Declining is a fair answer too. If the client wants a firm price, a short deadline and no deposit on a backlog with missing years, the job is likely to cost more than it pays.
