Z-ERP by Z Systems is a POS, inventory, and accounting system for retailers with one or many branches. It runs in the cloud with sync across branches and warehouses, and offers a local edition that works fully offline and syncs when the connection returns. Per-cashier permissions and a tamper-evident audit log of voids, discounts, and price edits protect the till. It issues tax invoices with QR codes, offers a ZATCA e-invoicing service for Saudi Arabia, and works with POS hardware.
