Using OCR on Scanned Receipts for Expense Reports
Manually retyping receipt data into your expense tool is slow. OCR turns receipts into copy-pasteable text in seconds.
Filing expense reports means transcribing receipts: date, vendor, amount, tax. Doing it by hand for 30 receipts takes an hour. OCR cuts it to 10 minutes.
The workflow
- Scan or photograph your receipts (most scanning apps save them as PDF)
- Combine them into one PDF if separate, using Merge PDF
- Run OCR PDF with the correct language (usually English for US receipts)
- Download the OCR'd PDF
- Open it, select-and-copy the text fields you need into your expense tool
OCR adds a hidden text layer to the receipt image. The visual receipt stays the same (good for attaching to expense reports as proof), but now the text is searchable and copyable.
Receipt-specific OCR tips
Use the right language pack. Running English OCR on a French restaurant receipt produces nonsense. Match the language to the receipt's country.
Higher DPI scans work better. 300 DPI is ideal. Phone photos taken in good light are usually adequate; faded thermal-printer receipts often hit 70-80% accuracy and need spot-checking.
Spot-check amounts. OCR can misread digits — especially on thermal-printer receipts where ink fades quickly. "1.50" vs "7.50" is a $6 error. Always verify the amount against the original image before submitting.
What OCR can't do
OCR doesn't understand semantics — it extracts text, but it doesn't know that "10.95" is the amount and "Starbucks" is the vendor. You still have to manually map fields. For automated receipt parsing, you need a specialized expense tool like Expensify, Concur, or Ramp that uses ML on top of OCR.
For occasional expense reports, OCR + manual mapping is the right level of effort. For high-volume professional receipt processing, the dedicated tools earn their cost.
Receipt photo quality tips
- Flat surface, no folds — wrinkled receipts produce skewed OCR
- Even lighting — avoid shadows from your hand or phone
- Crop tight — remove the table/desk background from the photo
- Use a scanning app's "document" mode which auto-corrects perspective
A 5-second photo with poor framing makes OCR 30% less accurate. The setup matters.
Bottom line
Combine receipts → OCR → copy-paste into expense tool. 30 receipts in 10 minutes instead of 1 hour. Always spot-check amounts before submitting.
