Signing on the device itself, clearance for standard invoices, reporting for simplified ones, an unbroken hash chain — and all of it continuing when the line drops.
Phase 2 is not one thing. These are the four documents, and what happens to each.
Cleared with ZATCA before it is issued to the customer. An uncleared invoice is not handed over.
Signed locally and printed immediately, then reported within 24 hours. This is the one that comes out during an outage.
For a return or refund, referencing the original invoice’s UUID.
For an upward adjustment, carrying its reason on the document.
Most systems say they work offline and mean they save the sale to send later. Here is what actually happens in Wameed when the line drops.
The status bar appears. Nothing else on the screen changes.
The catalogue, prices and promotions are all on the device. Even the discounts run through the same engine.
The private key is in the OS secure store. A simplified invoice is signed inside the legal 24-hour tolerance.
With the nine-tag QR. It is a legal invoice, not a placeholder slip.
Transactions first, then stock, then the catalogue. Each row is acknowledged before it is cleared.
If your accountant or technical adviser asks what exactly is implemented, this is it.
A limit we state out loud
The automatic sweep covers pending and rejected invoices only. An invoice carrying a warning, or one a person has excluded from submission, is never sent automatically — that exclusion is a human decision and stays one.
Straight answers, with no “speak to sales” in place of one.
Yes, natively. Wameed produces UBL 2.1 XML invoices with the previous-invoice hash chain, signs them with a production certificate held on the device, generates the Phase 2 QR including the hash, stamp and public key, and reports simplified invoices within the 24-hour window. Standard B2B invoices go through clearance.
Phase 2 explained the way a shop owner needs it, not the way a circular writes it.

Getting this wrong is the most common Phase 2 mistake. The two invoice types follow different flows, carry different fields and have different deadlines — and your POS must choose correctly at the counter.

The square on your receipt is a signed data structure, not a link. Here is exactly what it encodes, why Phase 2 added three fields to it, and how to verify your own printer is producing a valid one.
