Reachable from anywhere.
SiztOS runs on a PC inside your shop, so billing never stops when the internet does. A secure, encrypted tunnel gives owners their own web address to check sales from home — no fixed IP, no open ports.
Tills keep billing over the shop network even if the internet drops.
Encrypted HTTPS, email-verified owner access, internal pages locked down.
Automatic nightly database backup, 15 days kept on the shop PC.
Each branch runs its own server; transfers move stock between them.
A single Windows installer sets up the database, app and shortcuts.
Arabic and English names, receipts and right-to-left printing.
Start with billing.
Grow into the full system.
Not every shop needs accounting on day one. Choose the edition that fits today — both run on the same installer, the same database and the same ZATCA engine.
