Missing receipts do not have to turn the whole bookkeeping file into guesswork. The practical task is to identify each gap, recover the strongest available evidence and make unresolved items visible. A bank statement helps establish that money moved; it may not explain what was bought, who supplied it or whether the expense qualifies for a particular tax treatment.

Start by distinguishing missing documents from missing transactions. A purchase can already be correctly recorded but lack its invoice. Conversely, a folder full of receipts can still leave out cash sales, payment-provider activity or a bank account nobody has reconciled.
Build a gap register before making corrections
Work account by account and month by month. Obtain complete bank and card statements, sales records, supplier statements and payment-provider reports. Compare these with the bookkeeping file and list the exceptions.
Use a simple register containing the date, amount, supplier or customer, account used, missing evidence, action owner and current status. Assign a reference to each item. This prevents three people chasing the same receipt while another transaction remains unnoticed.
Prioritise gaps that affect an approaching filing date, substantial purchases, unusual transactions or amounts owed to customers and suppliers. Then clear routine smaller items in batches. Do not assume that a low-value transaction is automatically irrelevant to VAT or other reporting.
Recover evidence in a sensible order
Ask the supplier for a duplicate invoice or receipt. Check online accounts, email attachments, archived mail and the purchasing employee’s records. For a marketplace purchase, obtain the seller’s document where available rather than relying only on an order confirmation from the platform.
For subscriptions, retrieve both the invoice and the billing period. For card settlements, recover transaction and fee reports. A statement showing a £970 deposit cannot explain £1,000 of customer sales and a £30 processing fee on its own.
| Available evidence | What it can help establish | What may still be missing |
|---|---|---|
| Duplicate supplier invoice | Goods or services, supplier and billed amount | Whether it was paid |
| Bank statement | Date, amount and payment destination | Detailed business purpose |
| Delivery note | Goods received | Final price and tax information |
| Customer remittance | Intended allocation of a receipt | Whether the invoice itself is correct |
| Employee explanation | Business reason and attendees | Independent purchase evidence |
Label recovered copies accurately. A reconstructed note should never be presented as an original supplier invoice.
Reconstruct a transaction without inventing it
Illustrative example: a £180 card payment appears against a stationer, but the receipt has disappeared. The supplier sends a duplicate invoice identifying paper and printer supplies. The bookkeeper matches it to the card payment, checks that the purchase has not already been entered and attaches the duplicate.
If the supplier cannot help, retain the statement and a dated explanation of what is known, who made the purchase and why it was for the business. Give that evidence to the accountant for a decision. Do not invent a supplier document, a VAT amount or a business-use percentage to complete an empty field.
Where several similar payments appear, check whether they are separate purchases, instalments or duplicates. A guess based on the supplier name alone can put loan repayments, deposits and personal spending into ordinary expenses.
Handle genuinely lost records explicitly
For companies, HMRC’s company record guidance says to recreate records as well as possible when replacement is impossible, notify the Corporation Tax office and explain the situation in the return. For self-employed returns, HMRC distinguishes estimated and provisional figures; provisional figures need replacement when actual figures become available.
These are reporting processes, not permission to choose favourable numbers. Keep the reconstruction method, supporting evidence and outstanding uncertainties together. Agree with the accountant which figures need further work before submission.
VAT needs separate attention. VAT recordkeeping guidance covers purchase invoices and other supporting records. A missing invoice should trigger a VAT evidence review; a payment visible in the bank does not by itself settle whether input VAT can be reclaimed.
Prevent the next backlog
Introduce one route for documents: a shared upload address, capture app or agreed folder. Require a business-purpose note for transactions that are not self-explanatory. Decide who checks uploads and how quickly missing documents are chased.
Run a weekly exceptions report rather than asking for everything at year end. Track unresolved items by age, not only value. Before an employee leaves or a supplier portal closes, export the relevant records.
The goal is a file that another person can understand without interviewing the entire business. EPOS bookkeeping services can be discussed around recovering incomplete records, reconciling the accounts and establishing a more reliable capture process.
