E-invoicing for POS software: till and B2B invoice from one API

Most POS providers cover the till, not the e-invoice — fiskaly covers both. Add compliant B2B e-invoicing to the platform your merchants already run, from the same partner as your fiscalization. A new revenue line, no new vendor.

Already on fiskaly: turn e-invoicing into your next revenue line

New revenue line

Monetise e-invoicing as a paid capability your merchants need — not a cost you absorb.

No new vendor

Same source as your fiscalization — skip the legal, security and procurement cycle you've already cleared with us.

Built for POS

Tailored to how POS works — not retrofitted from a generic invoicing tool.

Live in days

A familiar partner plus a developer-ready API. Free to test, no contract to start.

Onboard at scale

An API management layer automates rollout, onboarding and taxpayer-account setup across your merchant base.

Compliance, outsourced

We monitor every market and ship updates before deadlines — no code, format or syntax changes on your end.

New to fiskaly: cover the whole transaction, from one partner

One partner, both mandates

One provider, one contract, one SLA for fiscalization and e-invoicing — instead of stitching two vendors together.

Not just a standalone API

A standalone e-invoicing API covers the invoice, not the till. fiskaly covers both.

Skip the in-house build

E-invoicing isn't a one-time feature — it's a permanent compliance team. One integration replaces the build.

Everything the mandate requires

Create, send, receive and correct structured e-invoices; output XRechnung or ZUGFeRD from one data model.

Built for all sizes

A unified management layer — integrate once, reuse everywhere, from single merchants to large chains.

Hosted in Germany

A cloud solution with German data residency most competitors can't meet.

Fiscalization and e-invoicing from a single provider — one contract, one SLA, one relationship. No second vendor to evaluate.

Compliance, outsourced
