Catch-Up Bookkeeping: The Document Checklist

Scope before you quote

Catch-up work — clean-up, rescue, whatever your practice calls it — is the most document-heavy job in bookkeeping and the one most reliably underpriced. The mistake is almost never the hourly rate. It is quoting before knowing what is missing.

The client says “I am about six months behind”. What that sentence usually means is: eleven months behind, one of the two bank accounts has no statements available online beyond the last twelve months, there is a period where the previous bookkeeper started and stopped, and no receipts exist for any of it. Every one of those is discoverable in twenty minutes, before you commit to a number.

The twenty-minute pre-quote check

Before you price anything: get read access to the ledger, look at the date of the last reconciled transaction on every account, count the accounts, and ask one question — does any of it have receipts. Those four facts move a clean-up quote from a guess to an estimate, and they cost you less time than one round of email.

How far back to go

Not as far as possible. As far as something makes you. Pick whichever of these is earliest and stop there.

Driver	How far back that takes you
The last set of finalised accounts	The default starting point. Everything before it has been signed off; you are rebuilding from the closing trial balance forward.
The last correctly filed sales tax return	If VAT, GST or BAS returns have been filed on wrong figures, the clean-up starts at the first bad period, not at the last good one — and there is a correction to prepare.
The current tax year	The minimum for a business that has never had books kept, because the return is due whether the books exist or not.
The date the entity started	For a business under two years old, go to the beginning. It is rarely much more work and it removes the opening-balance guesswork entirely.
What the bank still holds	The practical ceiling. Many banks keep only 12 to 24 months of downloadable statements. Beyond that the client has to formally request them from the bank, which takes weeks and sometimes costs money — find this out on day one, not in week four.

That last row is the one that wrecks timelines. If the job runs back further than the bank’s online archive, the statement request has to be the very first thing you trigger, because it has a lead time nothing else in the job has.

The per-month pack

Request this for every month in scope. Structure the ask by month rather than by document type — “March: statements, receipts, invoices” is something a client can work through in order; “all statements for the last eleven months” is a pile they look at once and close.

Statements for every account and card, for the full month. PDF for the balances, and CSV as well if you are importing the transactions rather than working from a feed. On a multi-month job you usually want both, and it is worth saying so once at the start rather than asking twice.
Merchant and platform payout reports. Stripe, PayPal, Square, Shopify, Amazon, the app stores. The bank shows a net payout; the report shows the gross sales and the fees. Reconstructing a clean-up without these is guesswork.
Sales invoices raised in the month. Paid or not.
Supplier bills and receipts. Realistically incomplete on a job like this. Ask for what exists rather than what should exist, and prioritise: large amounts, anything that looks like an asset, anything where the tax is worth reclaiming.
Payroll reports for the month, if there is payroll.
A note of anything unusual. A large transfer, a loan drawdown, money put in or taken out by the owner, an asset bought outright. One line per event saves you an hour of investigation each.

The collect-once pack

These do not repeat per month. Ask for them all at the start, because several have long lead times and every one of them changes how you treat the monthly data.

Last filed accounts or tax return, and the closing trial balance behind it
Every sales tax, VAT, BAS or GST return filed in the catch-up period, plus the workings
All correspondence from the tax authority in the period, including the unopened envelopes — penalty notices change the priority order of the whole job
Loan, lease and finance agreements, with the balance at the start of the period and now
Details of any assets bought or sold in the period, with the invoices
Owner or director drawings, capital introduced, and any inter-company transfers
The full list of accounts and cards, including closed ones — a closed account still had transactions in the period, and a client will not think to mention it
Access to whatever ledger exists, plus a backup or export of any previous one
Contact details for the previous bookkeeper, and permission to contact them

Ask for the closed accounts explicitly

The most common source of a stubborn unreconciled difference on a catch-up job is an account that was closed partway through the period. The client does not mention it because in their mind it no longer exists. Ask the question in those words: “were any accounts or cards closed during this period?”

The order to request it in

Sequencing matters more here than on a monthly close, because the client’s willingness is finite and largely spent in the first fortnight.

Access, and anything with a lead time. Ledger access, tax authority authorisation, and any bank statements that have to be formally requested. All on day one, before anything else.
The collect-once pack. Mostly things the client can find in a single sitting, and it tells you what shape the job really is.
Statements, month by month, oldest first. Work forwards. Reconciling in order means each month’s opening balance is already proven, and a difference surfaces in the month it was created rather than at the end of the whole job.
Receipts last, and only for what you actually need. After the statements are in you know exactly which transactions lack support. A list of forty named transactions is a task; “all your receipts for last year” is a reason to give up. Send it as one finite list rather than a standing obligation.

If the receipts stall — and on a catch-up job they usually do — the escalation sequence for a client who never sends receipts applies here, with one adjustment: the consequence you name is the reclaimable tax across the whole period, not one month. That number is often large enough to be genuinely motivating.

What to do about the gaps

Some of it will not arrive. That is normal on a catch-up and it needs a documented approach rather than an ad-hoc one, because a clean-up with undocumented assumptions in it is a liability you are carrying for years.

Missing statements: the client requests them from the bank. Not optional. You cannot reconcile without them, and a job you cannot reconcile is not finished, whatever it looks like on screen.
Missing receipts: post to a holding or unsupported-expenses account, do not claim the input tax, and list them for the client in writing. Never guess a category to make the ledger look tidy — a guess is invisible in six months and a holding balance is not.
Missing opening balances: reconstruct from the last filed accounts plus every statement since, and state in writing that the position is derived rather than handed over.
Unidentifiable transactions: one list, sent once, with dates and amounts. Not a running series of individual questions — the client will stop reading after the fourth.
Write down the assumptions. Every one of them, in a short document issued with the finished work, signed off by the client. This is the single most valuable half hour of a clean-up engagement.

The catch-up request email

The tone matters more here than anywhere else in bookkeeping. Anyone eleven months behind on their books already feels bad about it, and a client who feels judged goes quiet — which is the one failure mode that kills the engagement.

Catch-up engagement — opening request

Subject: Getting your books up to date: what I need, in order

Hi [Name],

Here is the plan for bringing [period] up to date. I have put it in the order that matters, so please work down it rather than trying to do all of it at once. This is a normal size of job — nothing here is unusual and nothing here is a problem.

FIRST — today if you can, because these have a waiting time attached:

1. Add me to [QuickBooks Online / Xero]: Settings → Manage Users → Accounting Firms → Invite, using [email].
2. Tell me every account and card that was open at any point since [start date] — including any that have since been closed, and any personal card used for business costs.
3. Check how far back your online banking lets you download statements. If it does not reach [start date], tell me now and we will request the older ones from the bank, which takes a few weeks.

SECOND — the one-off documents:

- Last accounts or tax return that was filed
- Every [VAT / BAS / sales tax] return filed since [start date]
- Any letters from [HMRC / the ATO / the IRS / the CRA] — including unopened ones
- Loan, lease or finance agreements
- Anything bought or sold over [threshold]
- Previous bookkeeper's contact details

THIRD — statements, one month at a time, oldest first. I will ask for these month by month so it does not become one enormous task.

RECEIPTS — leave these for now. Once the statements are in I will send you a specific list of the transactions that need support, which will be a lot shorter than sending me everything.

If something does not exist, tell me it does not exist rather than leaving it blank. That is genuinely useful and it stops me chasing you for something that was never there.

[Your name]

Why these jobs get underpriced

Practices quote clean-up work on the transaction count, because that is the thing you can see. The transaction count is not the cost. The cost is the number of times you go back to the client for something, and that is a function of how many months are in scope, how many accounts there are, and how disorganised the client is — none of which appear in a transaction count.

Two adjustments that make these jobs profitable:

Price the collection separately from the bookkeeping, or at least estimate it separately in your own workings. On an eleven-month catch-up across three accounts, chasing is frequently the larger half of the job.
Put a condition in the engagement, not just a fee. Something as simple as: the estimate assumes documents arrive within seven days of each request, and if they do not, the timeline moves and the estimate is revisited. It is a normal commercial term, and it changes client behaviour on the very first request.

Landing them on a monthly cycle afterwards

The real value in a catch-up is not the catch-up. It is that a client who has just paid to climb out of an eleven-month hole is, for a short window, extremely receptive to a system that stops it happening again. That window closes in about a month.

Set up the recurring request while you are finishing the clean-up, not after. Same document list, same wording, going out on the same day every month. The free month-end close checklist tool will generate the standing list for their industry and cadence if you want a starting point, and the new client document checklist covers anything the clean-up did not already surface.

ClientVault is built for exactly this shape of work. A catch-up is a lot of similar requests across many months, so you build the item list once and reuse it, each item carrying its own instruction and accepting as many files as the client wants to put against it — “March statements” is one line, not four. The client opens a link with no account and no password, which matters when you are asking someone overwhelmed to do eleven months of admin. Reminders go automatically at day 3, 7 and 14. When the clean-up is done, the same list becomes a monthly recurring request and the problem does not come back.

Free for three clients, no card. It is new, built by one person, and the comparison page is candid about where the established alternative is better.
