Your clients grow, not your integration
When an Italian client opens in Germany, France, or Spain, they ask you to support local invoicing compliance. Without a multi-country layer you either build each market from scratch or tell them you cannot follow. fiskaly covers SDI and the new European mandates through one integration — so following a client becomes a configuration decision, not a new project.
Features of the fiskaly. SIGN IT e-invoicing API
- Built for POS, ERP, and system integrators
Designed for the teams who embed compliance in someone else's product. One API integration instead of months of country-specific development — fiskaly handles the regulatory complexity.
- SDI and corrispettivi telematici from one API
Everything your merchants owe the Agenzia delle Entrate, receipts and invoices, under a single integration and a single contract.
- One integration, multiple mandates
Italy's SDI today, with new European markets activated progressively as ViDA-driven mandates come into force.
- Dev-to-dev support included
Clear technical documentation and a real engineer on the other side. No bots.
- Live in 1–5 days
Typical integration time, with a free sandbox so your team can validate before any commercial conversation.
- Certified security you can trust
ISO 27001 certified, with a BSI-certified Cloud TSS behind the platform.

FAQs
Under D.Lgs. 127/2015, all Italian VAT holders have had to issue B2B and B2G invoices as XML through the Sistema di Interscambio since 2019. B2C is optional but increasingly adopted. Any POS vendor, ERP, or system integrator serving Italian businesses has to handle FatturaPA XML, transmission through the SDI, and the response flow — acceptance, rejection, and notifications.
It can, but that is not the main reason vendors move. Aruba, InfoCert, and Namirial cover Italy well. What they do not cover is the next market your client expands into. fiskaly covers SDI and other European mandates through the same integration, so Italy keeps working and expansion stops being a new build.
Italy — SDI and FatturaPA — is live today. Beyond Italy, new markets are activated progressively as regulatory mandates come into force, including the ones driven by the EU's ViDA initiative. Talk to our team for the current market-by-market status for your rollout plan.
VAT in the Digital Age is the EU directive driving progressive adoption of e-invoicing and digital VAT reporting across member states through 2030. Member states are moving at different speeds: Poland's KSeF became mandatory in February and April 2026, France requires all businesses to receive e-invoices from 1 September 2026 with large and mid-sized companies also issuing, and Germany requires issuing from January 2027 above €800,000 in turnover and from all companies in January 2028. If you serve clients in more than one country, each date is a separate integration unless your provider absorbs it.
Yes. SIGN IT covers corrispettivi telematici, and e-invoicing runs on the same API, the same vendor relationship, and one contract. For vendors already using fiskaly for corrispettivi, adding e-invoicing does not mean a second integration project.
No. Sandbox access and the technical documentation are free and open, with no commercial process attached. Typical integration takes 1–5 days.
