Start with a flat receipt and even light.

Unfold the receipt and place it on a surface that contrasts with the paper. Hold the phone above it rather than shooting from the side. Keep your fingers clear of the text and move away from a window or lamp if the light leaves a bright patch across the total.

The test is simple: can you read the receipt in the saved image? A photo can look sharp at thumbnail size while the date or individual items are unreadable. Open the image and inspect those smaller details before putting the paper away.

Include the edges, items and total.

Frame the whole document. The merchant may be at the top, payment details near the bottom and the final amount below a folded section. Cutting away apparently empty paper can also remove a date or the last line of a long receipt.

For a long receipt, check that one image is still readable when enlarged. If your capture tool supports several pages, use that deliberately and check every page. Do not assume a camera-roll panorama or an extreme crop will remain legible in the report you send.

Check the saved crop, not just the camera view.

Automatic edge detection can mistake the table or a fold for the receipt boundary. After capturing, inspect the result for missing corners, a cut-off total and text that has become faint. Google Drive’s Android scanning help includes crop, rotation and retake controls; whichever tool you use, review its output.

In BillBack, check the image and the extracted merchant, date and amount. Correct a misread field before saving. Accurate scanning of the total does not prove that the itemized image is clear enough for someone else to review.

Fix the specific image problem.

  • Glare: change the angle of the light or the receipt, then photograph it again.
  • Blur: steady the phone, let the camera focus and retake the image.
  • Faded text: try more even light and compare the saved image with the paper.
  • Cut-off details: leave a little space around all edges before capturing.
  • Folded items: flatten the paper so the hidden line is visible.

A legible total can still be incomplete proof.

Imagine a restaurant receipt showing a $42.80 total, while a thumb covers the purchased items. The amount is readable, but the reviewer cannot see what the purchase contained. Photograph the document again with the item section exposed; do not type a guessed item description into a note to replace the missing image.

Princeton’s own guidance is one example of a reviewer asking for legible, itemized documentation. It does not set the rules for your employer. Check what your reviewer needs before discarding any original or replacing an itemized receipt with a card-terminal slip.

Keep the photo with its expense.

After checking the image, save it with the purchase record. Add the work purpose while it is fresh: which visit, job or meeting it belongs to. That is more useful later than a well-photographed receipt sitting among unrelated pictures.

Before exporting a BillBack report, inspect the receipt pages as well as the summary. If an image is missing or unreadable, resolve it before sharing. Keep the original paper for as long as your organization requires; taking a photo alone does not establish its retention policy.
