Intelligent Extraction for Receipts

A receipt is not a PDF. It's thermal paper that fades in a wallet over a few weeks, a photo taken at an angle under bad restaurant lighting, printed in a font size that seems designed to be squinted at. Whatever reads that document has to work with what actually got captured, not with a clean digital original.

Receipt data extraction is a physical-artifact problem before it's a data problem. Glyf's Data Extraction Engine reads receipt photos, scans, and PDFs, and returns structured fields (merchant, date, total, tax, line items, payment method) from whatever condition the paper or the photo happens to be in.

Why are receipts a harder extraction problem than invoices?

Invoices are designed to be read: clean layout, a formal number, a predictable place for the total. Receipts were never designed with extraction in mind; they were designed to fit on a small thermal roll and get handed across a counter. That difference shows up in every part of the document: font sizes shrink to fit more onto less paper, totals get crammed next to tax and tip with no consistent spacing, and the print itself starts fading within weeks on cheap thermal stock. Add a photo instead of a scan (taken one-handed, under whatever light was available, at whatever angle felt natural), and the source material is working against you before extraction even starts. That's the gap between reading a formal invoice and reading a receipt: one is a document built for review, the other is a physical object that happened to get photographed.

What a receipt photo needs before it becomes usable data

Photo quality is the single biggest lever on how clean a receipt extraction turns out. Glyf accepts PDF, JPG, PNG, and WEBP files, and checks type, size, and duplicates the moment a file is added, before anything gets processed. A receipt photographed flat, in even light, with the full receipt in frame, gives the engine the clearest possible read. One photographed at an angle, cropped at the edges, or shot in dim light gives it less to work with, and that shows up later as fields the engine couldn't confidently fill. Receipt photo best practices covers the specific habits (lighting, angle, distance) that make the difference between a clean first read and a flagged one.

Faded and crumpled receipts still return something you can review

Thermal paper fades. Receipts get folded, stuffed in pockets, and photographed weeks later once the print has already started to go. Glyf still processes those documents (it doesn't reject a receipt for being imperfect), but a badly faded or partially unreadable receipt is more likely to come back with a field the engine couldn't confidently fill. When that happens, the document is flagged Needs Attention instead of exporting a blank total or a guessed number. Faded and crumpled receipts walks through what typically still comes through clean versus what usually needs a manual check on documents in that condition.

Where do tips and service charges end up?

The bottom of a receipt is where most of the confusion lives. Subtotal, tax, tip, and service charge often sit stacked within a few lines of each other, sometimes with no clear label distinguishing one from the next. There's no dedicated tip field among the extracted data. A tip typically surfaces as a line item if the receipt itemizes it, or folds into the total cost if it doesn't. That's a real limitation worth knowing before you rely on an export for expense reporting that separates tips from the rest of the bill, and it's exactly the kind of detail worth a quick check in the drawer rather than an assumption. Tips and service charges covers how that specific case tends to show up in the extracted output, and what to look for before exporting a batch of restaurant or service receipts.

Review, correction, and export without one bad photo holding up the batch

Every processed receipt lands in a results table with the original image on one side and every extracted field, directly editable, on the other. If one receipt in a batch fails outright (unreadable, wrong file type, a duplicate), the rest of the batch still completes; a single bad photo doesn't stall documents that came through fine. That review loop is what makes photo-based extraction usable at scale: you're not trusting a machine-read total blindly, you're checking it once, quickly, against the image sitting right beside it.

Where receipt data extraction stops and invoice extraction starts

Receipts are photographed artifacts first. Invoices are structured B2B documents first: multi-line, tax-itemized, built around a formal number and a due date. If what's actually piling up on your desk is supplier paperwork rather than crumpled receipts, intelligent extraction for invoices covers that different problem: line items, multi-rate tax, and payment terms, instead of photo quality and fading.

Two questions about receipt condition

Does a faded thermal receipt still get processed? Yes. It's read like any other document, but a badly faded original is more likely to need a manual field check afterward.

What if a receipt photo is cropped or blurry? It's still accepted and processed; fields the engine can't confidently read get flagged Needs Attention rather than left blank or guessed.
