Document Scanner Guide

Scan Receipts Online

Expense software wants a picture of the slip, not a picture of your palm and the slip. Flatten the curl, kill the flash, crop to the paper. File it the same day thermal ink starts fading.

Thermal paper is trying to disappear

Shoot before the fade

Heat and sunlight bleach till tape. Capture the same evening. A perfect crop of a blank ribbon helps no one at tax time.

Curl, glare, and wallets

Unroll the slip. A glass table plus flash is a white rectangle. Side light, no flash, flatten with a notebook.

This is not bookkeeping software

We make a readable image or PDF. You still type the amount in Expensify, QuickBooks, or a spreadsheet. OCR of tiny thermal type is unreliable; do not bet an audit on it.

How it works

  1. 1

    Uncurl and flatten

    A heavy book on the slip for ten seconds is not glamorous. It works.

  2. 2

    Fill the frame with the tape

    Long receipts: shoot in sections and use multi-page, or overlap two photos. Do not shrink a meter of paper into one distant shot.

  3. 3

    Check the total and the date

    If either is unreadable, reshoot. Those two fields are why you bothered.

Use cases

Mileage and meal expenses

A PDF or JPEG the finance bot will accept on Monday morning.

VAT packs

Keep the merchant name visible. Cropping off the header is how refunds die.

Shared wallets on a trip

Capture now; split later. The slip will not get more legible in a backpack.

Problems we solve

Flash on glossy till tape

You photographed a light bulb. Turn flash off.

Fingertips in the frame

Crop them. They are not a deductible.

Chat-app compression

WhatsApp will smash the total into mush. Export from this tool, then attach the file — do not screenshot the screenshot.

Privacy & security

On-device

Merchant names and card tails stay in your tab.

No fake “AI bookkeeper”

We will not invent line items. You can read the slip or you reshoot.

Works with the office spoke

Printed A4 invoices belong there. This page is the skinny tape.
