Two jobs, done from one place.
Every sale creates a legal obligation and a customer moment. fiskaltrust covers both.
Compliance
Each EU country writes its own fiscal rules. We keep every transaction legal, in each country's format, and update centrally when the law changes.
- Fiscalisation: signing, numbering, daily closing
- Real-time reporting, ready for the ViDA shift
- E-invoicing over Peppol, B2B, B2C and B2G
- Audit-ready archiving per national retention rules
Experience
The same integration improves the checkout itself, for the merchant behind the counter and the customer in front of it.
- Digital receipts by QR, email, text or wallet
- Payment with the major providers
- InStoreApp: one checkout interface
- Feedback, warranty and loyalty built into the receipt
Integrate once. We map the rest.
POS systems connect to each EU country's fiscal infrastructure through one API. The open-source fiskaltrust.Middleware maps local requirements and updates centrally when regulation changes, so your integration code stays untouched.

What many people are asking.
What is fiskaltrust?
fiskaltrust is fiscal middleware for POS systems. A single API handles fiscalisation, e-invoicing, digital receipts and payments across EU markets, and updates centrally when tax law changes so your integration code stays untouched.
Which EU countries and fiscal standards does fiskaltrust support?
fiskaltrust supports ten EU markets today: Austria (RKSV), Germany (KassenSichV/TSE), France (NF525), Italy (RT), Spain (Verifactu/TicketBAI), Portugal (Portaria 363/2010), Greece (myDATA), Belgium (GKS 2.0/FDM v2), Poland (KSeF) and Denmark (SAF-T), with more markets on the way. Each transaction is produced in that country's required legal format.
Do I have to change my code when a country's tax law changes?
No. The open-source fiskaltrust.Middleware maps each country's local requirements and updates centrally when regulation changes, so your integration stays the same. You keep your existing POS, till, app or ERP setup.
How much does fiskaltrust cost?
The Middleware entry tier is free to start and costs nothing. You add products and services only when you need them, and commercial partners can access volume pricing.
Is fiskaltrust open source, and where can I host it?
Yes, the full Middleware code is public on GitHub, so you can verify exactly what runs at your point of sale. You can run it locally, in the cloud, or hybrid, and it works with existing POS and ERP systems.
What does fiskaltrust mean for consumers and their receipts?
Every receipt is legally valid, signed and stored, and can be delivered by paper, email, text or digital wallet. No app, no tracking and no personal data are required.
What is ViDA and is fiskaltrust ready for it?
ViDA (VAT in the Digital Age) is the EU's VAT reform, adopted by the Council on 11 March 2025 and in force since 14 April 2025. It makes structured e-invoicing and digital reporting mandatory for intra-EU B2B transactions from 1 July 2030, with existing national e-invoicing systems harmonising to the EU standard by 1 January 2035. fiskaltrust's real-time reporting and Peppol-based e-invoicing (B2B, B2C and B2G) are already built for the ViDA shift, and the Middleware updates centrally as each country implements its rules, so your integration stays untouched. Exact rollout dates vary by member state.
