Most cash registers in Serbia require training, dedicated hardware and patience. Tezga eKasa goes the opposite way: open it in your browser, type one sentence - and the fiscal receipt is issued. No installation, no mandatory fiscal printer, no software you study for days.
A sentence instead of a training course
The register has an assistant that understands plain language. Type: "Issue an invoice to Librum for book editing, 62,000 dinars" - and Tezga recognises the buyer, the service and the amount, builds the receipt and fiscalises it with the Tax Administration. Works for quotes and advance invoices too.
Everything in one place
- Fiscal receipts with a verification QR code - registered directly with the Tax Administration
