Missing receipts: what a bookkeeper can do when the client has lost them

Sooner or later a client says the receipts are gone. Panic is not needed: for most purchases the proof can be rebuilt from other records, and for the rest you can write down what happened and move on. Rules on what counts as adequate support differ by country and by type of expense, so check yours or ask your tax adviser before you decide what to book or deduct. This guide is about the bookkeeping routine, not tax advice.

First, sort the gaps by size and risk

List every transaction with no support and sort by amount, largest first
Separate routine recurring payments (software, utilities, rent) from one-off purchases, because the routine ones are easy to rebuild
Flag anything unusual: cash payments, round amounts, transfers to individuals, large purchases of equipment or travel
Handle the top few by value first; chasing a small receipt costs more than it is worth

Rebuild support from other records

Ask vendors for a duplicate invoice or receipt: most cloud tools and online shops let you download past invoices from the account
Search the client's email inbox for the order confirmation or billing notice
Use the card or bank statement line plus the vendor's name and date as the baseline record
For recurring charges, one invoice and the matching statement lines is usually enough to document the pattern
Check the payment app (PayPal, Stripe, Square, Venmo for business) for its own transaction history

Stop chasing clients for documents by hand.

When nothing can be recovered

Ask the client to write a short note with the date, amount, who was paid, what for, and the business purpose
Keep the note with the transaction so the reason is not lost again
Do not invent or recreate a receipt as if it were the original
Decide with your adviser whether the expense is supported well enough to claim; leave it as an owner draw or uncategorized only if that is the honest answer

Copy-paste email to the client

Subject: Quick question about [N] payments with no receipt
Hi [Name], I am closing [month] and these payments have no receipt or invoice attached: [list with date, amount, payee]. If you have the receipt, forward it by [date]. If it is lost, no problem: reply with what it was for and the business reason, and I will record that instead. For [vendor], you can usually download the invoice from your account under Billing.

Make it stop happening

Ask for receipts as part of the monthly request, with a due date, not at year endSend phone-scanning and file-naming instructions with every request (copy-paste wording: /guides/how-to-ask-clients-to-scan-and-name-documents)
Give clients one easy habit: photograph the receipt the moment it is handed over, or forward the email to a shared inbox
Turn on receipt capture in your accounting software if the client will use it
Keep a short list of recurring vendors whose invoices you can fetch yourself
Name the missing items in each reminder rather than writing "please send your receipts"

Where DocNag fits

Missing receipts are a symptom of asking late and vaguely. A recurring request with a checklist of what you need each month, one private link, and automatic reminders that name the open items makes the receipt part of the close instead of a scramble afterwards. The checklist below is prefilled with the month-end items; add receipts for large purchases to suit each client.

Frequently asked questions

What can I do when a client has lost a receipt?

Rebuild the support from other records: download a duplicate invoice from the vendor's account, search the client's inbox for the order confirmation, or use the card or bank statement line with the vendor name and date. For recurring charges, one invoice plus the matching statement lines usually documents the pattern.

What if nothing can be recovered?

Ask the client to write a short note with the date, amount, who was paid, what for, and the business purpose, and keep it with the transaction. Do not recreate a receipt as if it were the original.

Which missing receipts should I chase first?

Sort the gaps by amount, largest first, and flag unusual items such as cash payments, round amounts, transfers to individuals and large equipment or travel purchases. Chasing a small receipt often costs more than it is worth.

How do I stop receipts going missing every month?

Ask for them in the monthly request with a due date rather than at year end, give clients one easy habit such as photographing the receipt when it is handed over, and name the specific missing items in each reminder. Rules on adequate support differ by country, so check yours with your tax adviser.
