Why e-invoicing matters now

Since 1 January 2025, businesses in Germany must be able to receive e-invoices. Transition periods apply to issuing them: until 31 December 2026, all invoice issuers may still use another type of invoice instead, such as paper. For a prior-year turnover of up to 800,000 euros, this period is extended to the end of 2027. After that, e-invoices are mandatory for transactions between businesses in Germany.

A PDF invoice sent by email is not an e-invoice. What counts is a structured electronic format under the European standard EN 16931 that machines can process, such as XRechnung. The German Federal Ministry of Finance explains the details in its FAQ on e-invoicing (in German).

Xcan takes the format questions off your hands and goes further: from the invoice to the booking to the figures for your advance VAT return.

What Xcan does

Four steps that belong together in Xcan, just like in the demo above.

  • Create

    Create invoices with line items, tax and totals, as XRechnung in a structured format.

  • Validate

    Checked against EN 16931 with required-field checks, such as invoice number, invoice date, buyer reference (Leitweg-ID), seller VAT ID and the totals check.

  • Book

    Mapping to SKR03 accounts, for example receivables, revenue and VAT, and export as a DATEV posting batch.

  • UStVA

    The figures of the advance VAT return calculated automatically and ready for review by your tax advisor.

Who Xcan is for

Xcan is built for companies that invoice other companies, in other words B2B, and want to introduce e-invoicing without an IT project of their own. As a SaaS, Xcan runs in the browser: sign in, create the invoice, validate, export.

Xcan is especially helpful when your accounting team or tax advisor works with DATEV. Invoices arrive with SKR03 account mapping as a posting batch where they are needed, and the figures for the advance VAT return are ready for review.

Xcan is a software service and does not provide legal or tax advice. For tax questions, your tax advisor remains the right contact.

Pricing: on request. Get in touch and we’ll advise you personally.

Standard or custom?

Xcan, our e-invoicing SaaS, may be the simpler option if you don’t need a custom integration or workflow.

The standard doesn’t fit? Besides the SaaS product, e-invoicing is also available as a custom solution with special ERP integrations and customer-specific approval rules. This includes, for example:

  • generating outgoing e-invoices in XRechnung or ZUGFeRD format directly from your existing billing data,
  • processing incoming e-invoices, meaning import, validation and data extraction,
  • connecting your ERP and accounting systems,
  • automatically matching invoices against purchase orders and delivery notes.

Frequently asked questions about Xcan

What is the difference between a PDF invoice and an e-invoice?

An e-invoice is a structured electronic format under EN 16931 that machines can process, such as XRechnung. A PDF file sent by email does not count as an e-invoice.

Does Xcan check whether my invoice is valid?

Yes. Xcan validates against EN 16931 and checks the required fields, such as invoice number, invoice date, buyer reference (Leitweg-ID) and seller VAT ID, plus the totals.

Can I hand the invoices over to DATEV?

Yes. Xcan maps the bookings to SKR03 accounts and exports them as a DATEV posting batch.

Does Xcan replace my tax advisor?

No. Xcan is a software service and does not provide legal or tax advice. The calculated UStVA figures are ready for review by your tax advisor.

Is Xcan also available with a connection to our ERP?

Yes. Besides the SaaS product, there is a custom solution with special ERP integrations and customer-specific approval rules.
