How to scan receipts for your accountant (and keep them findable)

Paper receipts have two problems. They pile up, and many of them — anything printed on shiny thermal paper, like gas station and restaurant receipts — fade until they're blank. A receipt that can't be read isn't much use to your accountant. Scanning them as you go solves both problems, and it takes less time than sorting a shoebox in April.

This guide is about the mechanics of scanning and organizing. What you need to keep, and for how long, depends on your situation — your accountant or tax professional is the right person to ask.

Scan them while they're fresh

Thermal receipts can start fading within months, faster in a hot car. The best time to scan a receipt is the day you get it. A habit that works: scan at the end of each day, or whenever you fuel up, then throw the receipt in one envelope per month in case you need the paper later.

Getting a readable receipt photo

Receipts are harder than full pages: they're narrow, curly, and often printed in pale grey.

1. Flatten it. Run it along the edge of a table, or put it under something heavy for a minute.
2. Use a dark background. A white receipt on a white counter is the hardest thing for any scanner to find. A dark surface makes the edges obvious.
3. Get the whole receipt in. The total, the date and the merchant name are usually at opposite ends. Long receipts can be scanned in two overlapping parts.
4. Avoid glare. Thermal paper is shiny. Turn the flash off and tilt the receipt away from bright overhead light.

In CrunchFile's Scan tool, the receipt is found and straightened automatically. For faded thermal paper, B&W Heavy pulls faint grey print back to readable black. For receipts with a colored logo or a stamp you want to keep, use Color Enhance.

Make them findable

A scanned receipt you can't find is almost as bad as a lost one. Two habits make a big difference.

Name each file consistently. Date first, so they sort in order:

2026-10-09 Shell fuel 84.12.pdf 2026-10-09 Office Depot printer ink 46.30.pdf

Date, vendor, what it was, amount. Your bookkeeper can see at a glance what every file is.

Use folders by month or by category. By month is simplest and matches how most bookkeeping is done. If you're signed in to CrunchFile, saved documents live in your document library and can be sorted into folders.

Pull out the numbers instead of retyping them. Running OCR (text recognition) on a scanned receipt turns the printed text into text you can copy — the total, the date, the merchant — into a spreadsheet or your bookkeeping software. See the guide on OCR for how that works and where it struggles.

Sending them to your accountant

• Monthly beats yearly. Sending a month's receipts as one combined PDF, or a folder, is far easier for a bookkeeper than a year's worth at once.
• Combine related receipts. One trip's hotel, fuel and meals can go in one PDF, in date order.
• Check the size. If email bounces it, compress the PDF to a target size; receipts in black and white compress very well.

A five-minute weekly routine

1. Scan the week's receipts (they take seconds each once you have a spot set up).
2. Name them date–vendor–item–amount.
3. Drop them in this month's folder.
4. On the first of the month, send last month's folder.

That's the whole system. It's dull, which is exactly why it works.
