Lost a Business Receipt? Rebuild the Evidence File
Start by asking the supplier for a copy of the missing receipt or invoice. Match that document to the payment, then add records explaining the purchase and its business purpose. If something is still missing, record the gap honestly. A note you write today can explain the file; it cannot become the original receipt.
What you’ll get from this guide: Build a traceable file for one missing purchase document and hand over any unresolved tax questions.
- Recover the supplier document before relying on a reconstruction.
- Link the payment, purchased items and business purpose.
- Record unresolved questions instead of inventing missing details.
A missing receipt is easier to fix while the supplier can still find the sale. This checklist is for an owner clearing a specific gap in the books, whether the payment came from a business account or a personal card.
Ask for a copy that identifies the actual purchase
Give the supplier the purchase date, amount, customer name and order or payment reference. Search your email, supplier portal and delivery records first; the document may already be there under an order number rather than the business name.
If the copy is incomplete or unreadable, ask for a clearer version. Keep the original email with its attachment. Avoid editing a supplier's invoice to add the information you think it should contain.
Connect the copy to the payment and the job
Match the amount to the bank or card statement. A single payment may cover several purchases, and a receipt may have been paid in instalments. Write down that connection rather than forcing a one-to-one match.
Then attach records created around the purchase: an accepted quote, job sheet, order confirmation or delivery email. The ATO's business record-keeping rules explain why records need to show the transaction and the basis of relevant calculations.
Fictional example: a $286 tools purchase for job J184. The amount is the payment seen on the bank statement; no tax calculation is made.
| Step | Evidence collected | What it explains | Still unresolved |
|---|---|---|---|
| 1. Supplier copy | Invoice T317, requested 15 September | Items, supplier and invoice amount | Check that it is the right transaction |
| 2. Payment record | Bank reference TX916, $286 | Which payment settled the purchase | A bank line alone does not list every item |
| 3. Existing job record | J184 materials list and delivery email | Why the tools were ordered | Separate any private items |
| 4. Reconstruction note | Written 15 September, links above | Where each fact came from | Tax treatment awaits document review |
Keep each document intact. The reconstruction note records its real preparation date and does not imitate a supplier document.
Keep income tax and GST questions separate
Don't treat a recovered bank entry as automatic permission to claim a goods and services tax (GST) credit. The ATO has specific GST-credit and tax-invoice requirements, including procedures for missing or incomplete documents. Give your registered agent the actual file and ask which requirement remains unmet before changing a lodged return or business activity statement.
The ATO's replacement-records guidance also covers help after a natural disaster or personal crisis. If that is your situation, explain it when asking for assistance. Don't assume those arrangements apply to an ordinary misplaced receipt.
Close the gap without rewriting history
Write a dated note stating what you remember, what existing documents support it and what you could not establish. Describe what you established: “supplier copy requested” or “purpose supported by job sheet”. Save “receipt verified” for a receipt you actually checked.
Missing purchase document register
Copy this blank template into your own files. Your records stay with you.
Once the missing document is found, link it to the register and record who checked it. Keep the earlier note so someone else can follow what happened. Use the broader record-keeping guide for storage and retention, and the asset register if the purchase was equipment that will stay in the business.
Key takeaways
- Recover the supplier document before relying on a reconstruction.
- Link the payment, purchased items and business purpose.
- Record unresolved questions instead of inventing missing details.
