Receipt photo bookkeeping: take usable photos and record each purchase once
A usable receipt photo shows the whole receipt, flat, in even light, taken straight on and in focus, on the day you get it. Name each file by date and merchant. A receipt often lacks what an invoice carries, such as your business name, the supplier's tax number and an invoice number, so ask for an invoice when you need one.

Taking a photo that can be read
-
Photograph it the day you get it
Thermal paper fades with heat and time. A photo taken the same day keeps what the paper may lose.
-
Flatten it
Smooth out curls under a book for a minute, or tape the receipt to a plain sheet. Creases cut through digits.
-
Light it evenly
Use daylight or an overhead light. Avoid flash, which washes out faded print, and keep your shadow off the paper.
-
Shoot straight down
Hold the phone parallel to the paper with the whole receipt in the frame, top to bottom. A document scan mode flattens and straightens in one go.
-
Read the total before you move on
Zoom in on the date, the tax and the total. If you cannot read them, retake the photo now, while the receipt is in your hand.
-
One receipt, one file, one name
Never stack receipts in one photo. Name the file with the date and merchant, such as

Attach it where the record lives
Attach the photo to the transaction, or file it where the whole team can find it. Keep the paper for as long as your rules require.
What a receipt often lacks
| Detail | On an invoice | On a receipt |
|---|---|---|
| Your business name | Printed as the customer. | Usually absent, since the sale is anonymous. |
| Document number | A unique invoice number. | A till or transaction number, if any. |
| Supplier tax number | Printed where tax is charged and rules require it. | Sometimes missing. |
| Line detail | Quantities, unit prices and descriptions. | Abbreviated names, often no unit price. |
| Tax breakdown | Tax shown by rate. | One tax line, or a code beside each item. |
| Payment terms | A due date and terms. | None. It was paid at the time. |
| Proof of payment | None until you pay. | The method and last card digits, which show it was paid. |
Recording a receipt without double entry
A photo is evidence, not a second transaction. Before you record anything, find out whether the purchase is already in the books.
- Check the bank or card feed first. If the purchase is already there, match the photo to that line instead of adding a new expense. See invoice vs bill vs receipt.
- Add the business purpose. A receipt shows what was bought, not why. One line such as client lunch or site supplies helps later.
- Ask for an invoice when you need one. Where tax can be reclaimed or a client will be rebilled, a receipt alone may not be enough. Ask at the till for an invoice in your business name.
- Keep the paper if your rules say so. Whether a photo can replace the paper differs by country and tax authority. Ask your accountant.
Three photos of one receipt
A receipt prints three items, 14.20, 9.75 and 21.30, a subtotal of 45.25, tax of 3.62 and a total of 48.87. Here is what each photo gives you.
- Cropped. The foot of the receipt is missing, so the tax and total cannot be read and nothing can be checked.
- Glare. A bright patch makes 9.75 read as 9.15. The items add to 44.65 against a printed subtotal of 45.25, a gap of 0.60, so the check fails.
- Flat and evenly lit. The items add to 45.25, tax brings it to 48.87, and everything ties.
Only the third photo is safe to record. The same checks are described in supplier invoice OCR: what to check.
What goes wrong
Faded thermal print
The ink fails first on the date and total. Photograph early and keep the paper, because a faded receipt may be unreadable to you and to OCR.
A cropped total
Photos cut off the foot of long receipts, where the tax, the total and the payment line sit. Check that they are in the frame.
The card slip kept, the receipt binned
A terminal slip shows the amount and the last card digits but no items. Keep the itemised receipt, not only the slip.
Handwritten tips and amounts
A tip added in pen or an amount changed by hand cannot be read reliably. Enter those from the paper.
The same purchase twice
Once from the photo and once from the card feed. Match them, and do not add both.
How BillToCSV helps
The receipt converter in BillToCSV reads receipt photos and PDFs, one receipt per file, into a review CSV with one row per item. It re-adds the items with the tax and turns a receipt amber when the sum does not match the printed total, which is how a cropped or glared photo shows itself. It does not choose expense categories or decide how a purchase should be treated. Free: 1 file per day, up to 10 pages, no account. Files over 10 pages are converted up to page 10 on the free allowance; a page code converts the whole file, up to 150 pages. See pricing.
Questions people ask
Is a photo of a receipt acceptable for bookkeeping?
For your own books, usually yes, as a working copy. Whether a photo satisfies tax or audit rules differs by country, so ask your accountant and keep the paper until you know.
How long should I keep paper receipts?
Retention periods differ by country and by type of record, so no single answer fits. Ask your accountant or check your tax authority's guidance.
Do I need an invoice if I already have a receipt?
Sometimes. A receipt shows that you paid, but an invoice carries your business name, a number and the supplier's tax details. Rules on reclaiming tax and rebilling clients differ, so ask what you must keep.
What can I do with a receipt that has already faded?
Ask the merchant for a copy, or use the bank or card record to confirm the amount and date and write them on the file. Photograph new receipts the day you get them.
Should I enter a receipt as a bill or as an expense?
If it is already paid, an expense is usually simpler because it leaves no open payable. Some firms enter receipts as bills and pay them at once. Pick one routine and use it every time.
Can software read a receipt photo?
Yes, with the usual OCR caveats. A flat, bright, in-focus photo of the whole receipt reads best, and the total and tax should still be checked against the paper.
