How to get fiscalized step by step (from tax ID to first receipt)
A practical checklist for fiscalization: what you need, in what order, and how to get from registering your business to your first valid fiscal receipt.
Fiscalization looks scary until you see it’s just a few clear steps. If you know the order, the whole thing wraps up faster than you’d expect. Here’s a practical checklist — from paperwork to your first receipt.
1. Business and tax ID
First you need a registered business and a tax ID. If you’re just opening a shop, that’s the starting point; if you already operate, you have it. This is also where it’s decided whether you’re VAT-registered, which later affects the tax labels on the receipt.
2. Security element
Next you need a security element — a card or file that signs receipts. The Tax Administration issues it on request. Without it the register can’t fiscalize turnover, so don’t skip this step.
3. ESIR and PFR
Then you pick a register — an ESIR (the program you work in) and a PFR (which signs and sends to the tax office). The easiest path is a software register that includes both, so there’s nothing to wire up. This also decides how fast your daily work will be.
4. First receipt
Once it’s all connected, you ring a test sale and out comes your first fiscal receipt with a QR code. Tezga eKasa is built to make this path as short as possible: add your items, connect the security element, and start selling.
