A busy season, a change of staff or a switch of software can leave months of transactions unrecorded. The longer it runs, the harder it is to see how the business is doing. This guide sets out a practical way to bring overdue records up to date, one step at a time.
Signs your records are behind
You may need catch-up bookkeeping if:
- your bank accounts in your software have not been reconciled for several months
- receipts and invoices are sitting in email inboxes, drawers or photo folders
- you are not sure which customers have paid or which suppliers you owe
- your software balance does not match your bank statement
- a VAT return, tax return or year-end is approaching and the records are not ready
- you have changed software and the old and new records do not line up
Why up-to-date records matter
Keeping records is a legal requirement, not just good practice. The rules depend on how your business is set up.
Sole traders and partnerships
If you are self-employed or in a partnership, you must keep records of your business income and expenses for your Self Assessment tax return. HMRC says you must keep them for at least 5 years after the 31 January submission deadline of the relevant tax year.
Some sole traders and landlords also need to use Making Tax Digital for Income Tax, depending on their qualifying income. For example, those with qualifying income over £50,000 in the 2024 to 2025 tax year should have started from 6 April 2026. Check whether and when it applies to you.
Limited companies
A limited company must keep accounting records, including all money received and spent, assets, debts owed to and by the company, and the receipts, invoices, bank statements and other documents needed to prepare its annual accounts and Company Tax Return. Records must generally be kept for 6 years from the end of the last company financial year they relate to. GOV.UK warns that a company can be fined £3,000 by HMRC, or a director disqualified, if accounting records are not kept.
VAT-registered businesses
If you are VAT registered, you must keep records of everything you buy and sell, including sales and purchase invoices and credit or debit notes. VAT records generally need to be kept for at least 6 years, and some must be kept digitally under Making Tax Digital for VAT.
Step 1: Define what needs catching up
Before you start entering transactions, work out the size of the job:
- the date your records were last complete and reconciled
- every account involved: business bank accounts, credit cards, loans, savings accounts and payment platforms
- your next deadlines, such as a VAT return, Self Assessment return or company year-end
- whether payroll, VAT or other areas are also behind
This gives you a list of periods and accounts to work through.
Step 2: Gather your records
Collect everything for the catch-up period in one place. That usually means:
- full bank and credit-card statements for every account, from your bank, not just a software feed
- sales invoices and any credit notes issued
- purchase invoices and bills from suppliers
- receipts for business expenses
- loan, finance and lease agreements
- payroll reports, if you employ staff
- previous accounts, tax returns and VAT returns, to confirm opening balances
Organise them by month so documents are easy to find.
Step 3: Work period by period
Start with the oldest period and move forward. Work one month, or one VAT quarter, at a time, and complete each period before starting the next. This keeps balances accurate as you go and makes errors easier to trace.
For each period:
- Record sales and purchase invoices.
- Match bank transactions to invoices, bills and receipts.
- Record remaining expenses with their supporting documents.
- Note anything you cannot identify as a query, rather than guessing.
If a deadline is close, you may need to prioritise the periods it covers. Even then, check that the opening balances for those periods are right.
Step 4: Reconcile as you go
Reconciliation is what turns a list of transactions into records you can rely on. At the end of each period, check that:
- each bank and credit-card balance in your software matches the closing balance on the statement
- unpaid sales invoices match what customers actually owe
- unpaid bills match what you owe suppliers
- VAT figures agree to any returns already submitted
- opening balances agree to your last accounts or tax return
Differences are easier to resolve one period at a time.
Step 5: Deal with missing records
Gaps are common in catch-up work. Before treating something as lost, try to replace it:
- ask suppliers and customers for copy invoices
- download statements and invoices from bank, card and platform portals
- search email for order confirmations and e-receipts
Keep a running list of queries and missing items, and work through it as documents arrive.
If records cannot be replaced, HMRC guidance sets out what to do. For Self Assessment, you must do your best to provide figures, using estimated or provisional figures and telling HMRC which you have used. For a limited company, GOV.UK says you should try to recreate the records, tell your Corporation Tax office straight away and include the details in your Company Tax Return. Ask your accountant how this applies to your position.
Choosing your software
Catch-up work is a good time to settle on the software you will use going forward. Look for software that suits your transaction volumes, handles VAT if you are registered, and lets you keep digital records and attach supporting documents to transactions.
If you plan to change software, decide before you start the catch-up. Moving to a new system at the end of an accounting period is usually simpler than switching partway through.
TaxSpex works with Xero, QuickBooks and Zoho Books. We agree the software, the level of access and how records and queries are exchanged before work begins.
How TaxSpex approaches catch-up bookkeeping
If your records are behind, we start by reviewing the periods involved, the transaction volumes, the software and the condition of the records. We then confirm the catch-up work and fee in writing before starting, separately from any ongoing bookkeeping.
Catch-up work can bring bank and credit-card reconciliations and sales, purchase and expense records up to date, with a list of queries and missing records for you to resolve. Once the records are current, bookkeeping can continue on an agreed cycle. You remain responsible for providing complete and accurate business information and answering queries.
