Scanning
Supported documents
What you can drop in, within which limits, and what React Box pulls out depending on the kind of document.
Updated on August 14, 2026
Formats and limits
The same rules apply to all three entry points.
- PDF — the most reliable format, including for multi-page documents.
- Images — a phone photo, a screen capture, a copier scan.
- 20 MB per file at most. Beyond that, the file can still be kept in the vault but not analysed.
- CSV and Excel — reserved for bank statements: they are read as a table, without going through image analysis.
What improves the reading
A full page, sharp, shot straight on and well lit is almost always read correctly. The usual traps are a document cropped at one edge, a photo taken at an angle, a stamp sitting on top of an amount, and faded thermal paper. A native PDF — the one your supplier issued — beats a photo of the same document printed out.
Note
Purchase invoice
The richest document type.
- The supplier — name, legal name, ICE, tax identifier, trade register, address and contact details.
- Its bank details — IBAN, RIB, SWIFT and bank name printed on the invoice.
- The invoice itself — number, issue date, due date, currency and period covered.
- The line items — description, quantity, unit price excluding VAT, VAT rate and amount.
- The totals — amount excluding VAT, VAT and total including VAT.
- A suggested ledger allocation, inferred from the line descriptions and from your own habits.
Cash receipt
A short document, four decisive pieces of information.
- The voucher number as printed on the receipt.
- The date the money came in.
- The amount received and its currency.
- The payer — the name read on the receipt, which React Box tries to match against an existing third party.
- The reason for the payment, when it is stated.
Bank statement
The most structured document, and the one that feeds cash analytics.
- The account — IBAN, RIB, holder, bank and currency, used to attach the statement to the right account.
- The period covered and the issue date of the statement.
- Opening and closing balances, framing the movement over the period.
- Each transaction — operation date, value date, description, reference, direction and amount.
What scanning does not do
Scanning reads accounting documents, not any document at all. A contract, a certificate or a letter dropped in the vault stays a readable file: it is not analysed and costs nothing. Likewise, no accounting entry is generated automatically — React Box prepares the data, your accounting firm keeps control of the books.
