From transaction to structured e-invoice

The receipt is already there. The e-invoice comes from it. Every sale on your till is already recorded with fiskaltrust. The add-on turns exactly those receipts into compliant e-invoices. No second system, no retyping.

A PDF is not an e-invoice.

True e-invoicing means exchanging invoice data in a structured, machine-readable format like XML, so systems process it automatically.

  • A PDF or paper invoice

    An image of an invoice. It cannot be validated or processed automatically, and it will not satisfy EU mandates.

  • A structured e-invoice

    Machine-readable data in an EU-compliant format, validated and exchanged automatically between systems and authorities.

One flow. Three ways in.

Every e-invoice is one job with three steps: create, transmit, track. What changes is only where the buyer identity comes from. Managed in the fiskaltrust Portal alongside every other receipt.

  • Method A

    In the back office

    After the sale

    Convert the receipts already in the fiskaltrust.Portal. Attach the buyer, generate, transmit.

    Integration: none.

  • Method B

    At the checkout

    During payment

    The fiskaltrust.InStoreApp captures the business identity at the sale and confirms it is transmittable.

    Integration: a small config.

  • Method C

    In your software

    Owned by the POS

    The POS drives create, transmit, and status through the fiskaltrust.PosSystemAPI, end to end.

    Integration: full API.

The mandates are dated.

E-invoicing is arriving country by country. Each market sets its own format, network, and date. These are the legal deadlines your merchants face. fiskaltrust availability is rolling out market by market.

  • AT

    ViDA path

    No B2B mandate yet

    B2G e-invoicing has been mandatory since 2014, using ebInterface or Peppol BIS. For B2B, structured invoicing is optional today. A mandate is expected under the EU's ViDA rules, most estimates point to 2027–2030, but no date is set in Austrian law yet.

  • DE

    1 Jan 2027

    B2B mandate takes effect

    Every business must already be able to receive structured e-invoices, that started 1 January 2025. Issuing becomes mandatory from 1 January 2027 for businesses over €800,000 turnover, and from 1 January 2028 for everyone else.

  • IT

    Live now

    SDI clearance since 2019

    Italy moved first. Structured e-invoicing through the Sistema di Interscambio (SDI) has been mandatory for B2B and B2C transactions since 2019, using the FatturaPA XML format.

  • FR

    1 Sep 2026

    Phased rollout begins

    From 1 September 2026, every business must be able to receive e-invoices, and large and mid-sized companies must issue them. Small and micro businesses follow on 1 September 2027.

  • PL

    Feb 2026

    KSeF issuance phases in

    KSeF became mandatory for large taxpayers (over PLN 200 million turnover) on 1 February 2026, and for all other VAT-registered businesses from 1 April 2026. Micro-entrepreneurs follow from 1 January 2027.

Developers

Build it into your software.

One integration against every mandate. National formats, networks and format migrations stay on our side of the line. You keep the API and credentials you already use.

  • Methods A and B need no code, your customers are compliant before you write a line
  • Method C: mark the receipt as a B2B invoice on the /sign call you already make, then /issue
  • Same PosSystemAPI, same CashBox, same headers, no new SDK

Commercial Partners

Bring it to your merchants.

The mandates are already dated in the five markets above, so merchants have the obligation before we have the button. The conversation starts now, and the dealers who answer first keep the account.

  • A per-document product you sell into your base without engineering
  • One monthly invoice, a revenue share on every merchant you manage
  • The InStoreApp your merchants already use gets one more button

Europe is moving from monthly reports to instant reporting.

ViDA, VAT in the Digital Age, moves compliance to the moment of sale. The rollout is phased, and the direction is set.

  • 2025–27

    Phased ViDA rollout

    KSeF in Poland, SDI in Italy, and Peppol across the majority of markets. Structured B2B and B2G mandates expand country by country.

  • 2028

    Universal B2B clearance

    Real-time digital clearance for all B2B transactions. The tax office becomes a live validator of every invoice, not a later auditor.

  • 2030+

    Unified EU VAT e-reporting

    Digital Regulatory Reporting (DRR) fully live. Traditional invoicing methods become obsolete across the single market.

Questions, answered.

Is a PDF an electronic invoice?

No. A PDF qualifies only when it carries structured, machine-readable data that meets EU standards. True e-invoicing uses formats such as XML that systems process automatically.

Do I need a separate integration per country?

No. One integration. fiskaltrust maps the format, picks the network, and meets the reporting rule for each market. You add a country by configuring the signature unit type, not by rebuilding.

Is e-invoicing the same as e-reporting?

No. They are separate processes. E-reporting is tax-focused and country-specific, and often needs broader business data. This page covers e-invoicing only.

When is my deadline?

It depends on your market. Germany mandates B2B from 1 January 2027. France phases in from 1 September 2026. Italy is already live via SDI. Poland phases KSeF from 2026. Austria has no B2B mandate yet. Confirm the current date for your market before acting.

How is it priced?

A flat 0.10 euro per document to the merchant, no tiers and no platform fee. Channel partners who sell and install the add-on earn a revenue share.
