ZATCA E-Invoicing

Saudi e-invoicing done right — pure-Python ECDSA signing, CSID onboarding, UBL 2.1 XML with TLV QR codes, clearance and reporting.

What it is

ZATCA E-Invoicing is the shared Phase 2 compliance engine across Galaxy projects — TMS, FTMS and erpgalaxy. It signs invoices with ECDSA SECP256K1, handles CSR and CSID onboarding in Compliance and Production, produces UBL 2.1 XML with TLV QR codes, and clears and reports through FATOORA.
