A fiscal receipt and an e-Invoice are not the same and don’t replace each other. Confusing the two is the most common mistake at small businesses - someone issues the wrong document, or issues two when one would do. The rule, luckily, is simple: who is your buyer.
Fiscal receipt - selling to consumers
You issue a fiscal receipt in retail, to the end consumer (B2C). When someone buys a coffee, bread or a service, they get a fiscal receipt and the data goes to the Tax Administration in real time. It’s the receipt with the QR code the buyer can scan and verify.
e-Invoice - selling to companies and the state
An e-Invoice is used between companies (B2B) and toward the public sector (B2G), via SEF (the e-Invoice system). If you sell to another VAT-registered company or work with the state, you issue an e-Invoice - not (only) a fiscal receipt.
When you need both
There are situations where both appear - e.g. an on-the-spot sale to a company that also wants an invoice. That’s why it’s a big advantage when the register and e-Invoices live in one tool: you ring the sale once and the system knows whether you need a fiscal receipt, an e-Invoice, or both.
In Tezga eKasa, fiscal receipts and SEF are in the same flow - no jumping between programs and no double entry of the same items.
Key takeaways
- Fiscal receipt = selling to consumers (B2C), real time to the tax office
- e-Invoice = selling to companies (B2B) and the state (B2G), via SEF
- Register + e-Invoices in one tool = no double entry and no confusion
Frequently asked questions
It depends on the sale. Often an e-Invoice is enough, but with on-the-spot payment a fiscal receipt can also apply. A tool that handles both makes the call easier.
If they do retail trade (e.g. a shop or hospitality), generally yes - fiscalization applies to the turnover, not to the tax status.
