Three Receipt Rules That Make OCR Behave

OCR is not magic; it is software. If you feed it garbage photos, you get garbage data. Here are the three non-negotiable rules for your team.

Garbage In, Audit Risk Out

You treat the expense app like a trash can. You snap a blurry photo while walking to the taxi, crumple the paper, and forget about it.

Then, the OCR engine tries to read it. It fails. It flags the transaction as “Review Required.” I have to open it. I have to squint. I have to guess.

If I guess wrong, we commit tax fraud. If I send it back to you, we waste three days. This is Efficiency Leakage. We are spending hours fixing seconds of laziness.

The Leak: The “Unreadable” Pile

In a typical month, 20% of receipts are flagged for manual review. 90% of those flags are due to User Error, not software error.

  • Thumb covering the total.
  • Receipt folded over the date.
  • Photo taken in a dark restaurant.

Every flagged receipt stops the automation pipeline. It is a blockage in the stack.

The Plug: The Three Rules of Capture

From today, we enforce the “Clean Capture” Standard. If a receipt violates these rules, it is rejected immediately. No arguments.

Rule 1: The Flat Surface Protocol Do not hold the receipt in your hand. The micro-shakes blur the text. Place the receipt on a table. Flatten the edges.

  • Meten is weten: If the OCR can read the corners, it can read the center.

Rule 2: The “Shadow” Ban Do not lean over the receipt so your body blocks the light. Turn on the flash. Always. Light is data. Darkness is ambiguity. Ambiguity gets you audited.

Rule 3: The Full Frame I need to see the Vendor Name (Top) and the Total/VAT (Bottom). If you cut off the top to zoom in on the price, I don’t know who you paid. If the receipt is long (like a restaurant bill), use the “Long Receipt” mode in the app.

Summary

This is not about being difficult. It is about speed. If you follow the rules, the money hits your bank account in 2 days. If you break the rules, the receipt bounces back to your inbox, and you get paid next month.

Help the robot help you. Flat. Flash. Full Frame.

FAQs

Can't the finance team just fix the bad photos?

No. We are expensive. Asking us to decipher your bad photography costs the company €5 per receipt. Do it right the first time.

My camera is bad.

You have an iPhone 15. Your camera is fine. Your lighting is bad. Turn on the flash.

What if the receipt is too long?

Take two photos. Top half, bottom half. Most apps handle this. Do not take one photo from 2 meters away.
