E-invoices and receipt QR codes: XRechnung, Factur-X and UBL in ReceiptBook

More and more suppliers send invoices as data instead of a picture of a page. A German supplier may email an XRechnung XML file, a French one a Factur-X PDF with the XML tucked inside. ReceiptBook reads both on your iPhone and files them next to your scanned paper receipts, in the same book and the same export.

Which e-invoice formats ReceiptBook reads

The label shows on the review screen as a card that opens Every line of the structured e-invoice, so you can read the invoice lines as the supplier sent them.

Because the data is structured, each value is taken as it is written: vendor, date, total, net, VAT per rate, currency, invoice number and the vendor's tax ID. Those fields carry the source From e-invoice instead of Read from scan. Apple Intelligence never runs on an e-invoice; there is nothing for it to guess.

How to add an e-invoice

E-invoices arrive by email or sit in a folder, so they come in through import rather than the scanner.

The share sheet takes up to 20 files at a time, each up to 50 MB. Sharing PDFs and importing folders covers those routes in detail.

The sums check

When the e-invoice is read, ReceiptBook runs a set of checks based on part of the EN 16931 rules. It looks at things like:

• whether the total with VAT is the total without VAT plus VAT
• whether the VAT breakdown adds up to the VAT total
• whether the line net amounts add up, including allowances and charges
• whether the amount due matches the total, prepaid amount and rounding
• whether required details are there, such as the seller's name, the invoice number and the issue date

If something is off, the document gets the warning E-invoice check ("The e-invoice data has a problem worth a look.") with the specific line, for example The VAT breakdown doesn't add up to the VAT total. It's a warning, not a block, so you decide whether to ask the supplier for a corrected invoice.

If a file ends in .xml but isn't UBL or CII, you'll see Couldn't read the e-invoice. The original is still stored, so nothing is lost, and you can fill in the details by hand.

The XML stays untouched

An XML e-invoice has no picture. ReceiptBook keeps the file exactly as received, with its SHA-256 fingerprint, and says so on the review screen: the XML file is kept unchanged and has no image to show. For a Factur-X invoice, the PDF itself is the original, with the XML inside it. Both go into the originals/ folder of the accountant package when you export.

QR codes on till receipts

Some paper receipts carry a signed QR code from the till. ReceiptBook reads these on the iPhone:

• Austria, RKSV: the receipt number, date and time, and the gross amount per VAT rate.
• Germany, TSE: the transaction number, time and the gross per VAT rate.
• Vietnam: the QR code printed on an invoice.

The QR values help fill the fields, which you still review. ReceiptBook doesn't verify the till's signature; that needs the till's certificate.

When the QR code and the print disagree

If the QR code gives a different total, date, invoice number, tax code or VAT split than the printed text, the document gets the warning QR differs from print: "The receipt's signed QR code gives other values than the printed text. Check them against the paper." The detail line tells you exactly which value differs, so you know where to look.

Vietnam: look it up on the tax portal

For an invoice in đồng with a valid Vietnamese tax code (MST), the review screen adds a Tax portal lookup card with the tax code, invoice symbol, number and total. Look up on the tax portal opens the government's e-invoice site in your browser. Nothing is sent from the app; you check the invoice there yourself.
