E-invoicing
Issued by itself with every sale
Paid booking, counter sale, package, gift card
Seconds after a sale is recorded, a signed simplified tax invoice is issued and reported to the authority. A refund issues a credit note tied to its invoice, the same way.
Linked directly with Fatoora
One OTP from the authority’s portal
Create the code from your business account and paste it in your dashboard: a compliance certificate is issued, the authority’s six tests pass automatically, then the production certificate. The certificate is in your business’s name, not a middleman’s.
A chain that never breaks
A counter and a hash on every document
Every invoice carries the hash of the one before it and a sequence number that never repeats, and an issued document is never edited or deleted. This is what the authority checks, and what protects you in any audit.
Every document’s status at the authority
Accepted, cleared, with notes
A table of everything the shop issued and the authority’s reply, automatic resubmission when the connection fails, and a warning thirty days before the certificate expires. Plus a monthly file for the accountant.

Spa
A session paid by mada or Apple Pay, with its QR invoice in the WhatsApp message and on the booking page.
Questions about this feature
Every VAT-registered business does, and the authority brings businesses into Phase 2 in waves by revenue. If you are not VAT-registered you do not need it.
No. WGTK links your shop directly with the Fatoora platform under a certificate in your business’s name, and issues and reports the invoices itself. No fee per invoice.
Invoicing starts the moment you switch it on. Earlier sales stay in your books as they are, and a document issued by WGTK is never edited or deleted.
A credit note tied to the original invoice is issued and reported like it. You can also issue one by hand from the dashboard for a refund the system did not record.
