Trainera issues the fiscal receipt for memberships, passes and shop sales, at the desk and online, and emails it to the member with the QR code. Included on every gym plan, with no fiscalization module to buy for each location.
Also available on Apple Watch & Wear OS
Fiscalization for gyms in Trainera means that every sale the gym records, a membership at reception, a package bought in the app or a drink from the shop, is confirmed by the tax authority from the same system that sold it. In Croatia, Slovenia and Montenegro Trainera signs and sends each receipt itself with the gym's own certificate. In Serbia and Republika Srpska the law requires an approved ESIR, so Trainera sends the sale to the gym's ESIR provider, which issues the receipt. In the Federation of Bosnia and Herzegovina and Brčko District certified fiscal devices are still required, so Trainera does not issue those receipts.

Memberships, passes and shop sales, whether reception records them or the member pays online in the app.
Each payment method follows the rules of your country, including bank transfers where the law fiscalizes them.
Issue a cancellation receipt for a refund or a receipt by hand at the desk. The original always stays on record.
If the tax authority or the ESIR cannot be reached, Trainera keeps the sale and sends the receipt again automatically.
Check the certificate or the ESIR connection from the dashboard before you issue a real receipt.
Receipts sit in Business Insights with the transactions, the books (KIR/KPR) and the cash flow your accountant needs.
On the Fiscalization page in Business Insights, pick the country your gym is registered in.
Upload your certificate and enter your premises and device codes, or enter the API address and key of your ESIR provider.
Send a test to the tax authority or the ESIR from the dashboard and see the answer straight away.
From then on every sale gets its receipt, and the member gets it by email.
Fiscal receipts are included on every gym plan, together with lockers and NFC cards, access control and the books in Business Insights.
Yes, included on every gym plan. In Croatia, Slovenia and Montenegro Trainera sends each receipt to the tax authority with the gym's own certificate, and in Serbia and Republika Srpska it issues them through the gym's approved ESIR provider. Members get the receipt by email with the QR code, for sales at the desk and online. The Federation of Bosnia and Herzegovina and Brčko District are not supported yet: they still require certified fiscal devices.
Croatia, Slovenia and Montenegro, where Trainera sends each receipt directly to the tax authority, and Serbia and Republika Srpska, where your approved ESIR provider issues it. The Federation of Bosnia and Herzegovina, Brčko District, North Macedonia, Albania and Kosovo are not supported, because they require certified local fiscal devices or software.
Not in Croatia, Slovenia and Montenegro: Trainera confirms the receipt with the tax authority and emails it to the member. In Serbia and Republika Srpska the receipt comes from your approved ESIR provider, so check with that provider what it needs on site. In the Federation of Bosnia and Herzegovina and Brčko District keep your certified fiscal printer, because Trainera cannot issue those receipts.
Trainera does not issue fiscal receipts there yet. The Federation still requires certified fiscal printers, and its new law allows cloud fiscalization only once the bylaws apply, expected by 2027, and only through certified local providers. Until then you run memberships, the door, payments and the books in Trainera and keep your fiscal printer for receipts.
Yes. In every supported country a package a member buys online gets its receipt the same way as a sale at reception, and the member receives it by email with the QR code.
Where the law asks for it. In Croatia every receipt to a person is fiscalized since 1 January 2026, bank transfers included, and Montenegro, Serbia and Republika Srpska also cover them. In Slovenia bank transfers are outside davčno potrjevanje, so Trainera does not send them.
No. Fiscal receipts are part of every Trainera gym plan, with no module to buy and no charge per location. In Serbia and Republika Srpska your ESIR provider bills its own service separately.
In Croatia a FINA application certificate, your OIB, the business premises code from ePorezna and a billing device number. In Slovenia a FURS certificate for cash registers with the premise and device IDs. In Montenegro a qualified certificate from Pošta CG or CoreIT with the business unit and ENU codes. In Serbia and Republika Srpska the API address and key of your approved ESIR provider. Confirm the details with your accountant.
No. Trainera issues the receipts and keeps the books of issued and received invoices (KIR/KPR), suppliers, payroll and cash flow in Business Insights, with a CSV export, so your accountant gets clean data. Tax filings stay with your accountant.
Book a call and we set up your certificate or ESIR connection with you, then your gym issues receipts from the same system that runs memberships and the door.
