Attachments and OCR

What you upload

You can upload images or PDFs of receipts and invoices. Receiptu treats these as attachments linked to your financial documents.

OCR output vs what you edit

When a document is scanned:

• The system stores a full extraction from OCR (in the backend this is often referred to as raw_data) as an immutable snapshot of what was read from the file.
• Amounts, dates, vendor names, and other fields you see in the app may be copies you can correct so your records match reality without losing the original extraction.

So: OCR = “what the file said”; editable fields = “what you treat as true for your administration”.

Why that matters

If something was misread, you fix the editable values; support and future features can still compare against the original scan output when needed.
