Go VAT-Compliant across Europe.

fiskaly provides cloud-based APIs for fiscalization, e-invoicing, digital receipts and data archiving — purpose-built for POS systems and omni-channel operators. Its solutions help POS vendors, retailers, and software providers meet country-specific fiscal and VAT compliance requirements across Europe, without building and maintaining the infrastructure themselves.

fiskaly is currently active in Germany, Austria, Spain, Portugal, Italy, France, and Sweden, covering regulations such as KassenSichV, RKSV, Verifactu, and TicketBAI. As regulations evolve, fiskaly updates its services automatically, so customers remain compliant without additional development effort.

fiskaly offers a REST API that integrates directly into existing POS software, requiring minimal development effort. POS vendors and software providers connect to fiskaly's cloud infrastructure via standard API calls, enabling their systems to handle fiscalization, e-invoicing, and digital receipt requirements without building or maintaining any compliance logic themselves.

Because fiskaly's solution is cloud-based, there is no additional hardware required. Fiscal data is processed and signed securely in the cloud, in line with the legal requirements of each supported country. This makes it straightforward to roll out compliance across multiple markets from a single integration.

A fiscalization API is a software interface that enables POS systems to cryptographically sign transactions and, if required, report them to tax authorities in compliance with local regulations — without additional hardware. fiskaly's fiscalization API covers KassenSichV in Germany, RKSV in Austria, Verifactu and TicketBAI in Spain, and fiscalization frameworks in Italy (Telematic Fees), France (General Tax Code), Portugal and Sweden (Cash Register Act).

An e-invoicing API enables businesses and POS systems to automatically generate, send, and receive structured B2B and B2G invoices in formats required by local tax authorities. As EU e-invoicing mandates roll out under the ViDA directive, an e-invoicing API ensures your system stays compliant across all markets without manual intervention.

Fiscalization refers to the process of securing POS transaction data with a digital signature to prevent tax fraud via manipulation — as required by e.g. KassenSichV, RKSV, or Verifactu. E-invoicing is the  digital exchange of invoices between businesses (B2B) in structured formats mandated by tax authorities. In some countries, these processes can be interconnected.

European VAT compliance looks different in every country. Fiscalization, e-invoicing, and (live-)reporting are each governed by separate national regulations — leaving POS vendors to navigate a fragmented landscape that changes market by market, and year by year.

fiskaly seamlessly handles these challenges leveraging its expertise in audit trails and live reporting from fiscalization since 2019 to expand into e-invoicing exchange from 2026. Years of deep regulatory knowledge keeps your POS system compliant across all markets without rebuilding from scratch.

fiskaly currently provides fiscalization APIs for Germany, Austria, Spain, Portugal, Italy, France, and Sweden, covering regulations including KassenSichV, RKSV, Verifactu, TicketBAI. And one e-invoicing API for up to 10 European countries until the end of 2026, including all existing fiskaly markets.

For certain local requirements, fiskaly offers additional fiscalization products for submitting data to authorities (fiskaly SUBMIT), data exports for audits (fiskaly DSFINVK DE) or data archiving (fiskaly SAFE). All products can be organized in our plattform, the  fiskaly HUB.
