About this Product

Germany's e-invoicing rules are landing in phases: from 1 January 2025 every domestic B2B business must be able to receive a structured EN 16931 e-invoice, and from 2027-2028 sending becomes mandatory by company size. A PDF emailed to a customer is no longer a legal invoice between German businesses — you need structured XML.

This is a build-to-order extension for Microsoft Dynamics 365 Business Central, not an instant AppSource download. ECOSIRE builds it in AL as a per-tenant extension, installs it directly on your Business Central environment (cloud or on-prem), and supports it afterwards. We tailor it to your number series, posting setup, dimensions and document layouts rather than handing you a generic app to configure alone.

On the outbound side, the extension produces XRechnung (pure UBL/CII XML) and ZUGFeRD (PDF/A-3 with embedded XML) from posted sales invoices and credit memos, validates every document against the EN 16931 semantic model and the German CIUS before it leaves the system, and attaches the result to the posted record. For public-sector (B2G) invoices it captures and routes the Leitweg-ID.

On the inbound side, vendor e-invoices are parsed straight into purchase invoice documents — header, lines, tax and Leitweg data mapped to your G/L and vendor setup — so AP no longer rekeys XML by hand.

Delivery uses your existing channels by default, with an optional Peppol Access Point integration when you need network delivery. Everything runs through standard BC primitives: table/page extensions, event subscribers on posting routines, the Job Queue for batch export, dedicated permission sets, and the BC REST/OData API for downstream automation. You own the source; ECOSIRE maintains it as the standard evolves.

What you get

A per-tenant Business Central AL extension (.app) built, installed and published on your environment by ECOSIRE

Source AL project handed over to you (table/page extensions, codeunits, event subscribers, permission sets)

EN 16931 + German CIUS validation engine wired into your posting flow

Inbound parsing configuration mapping vendor e-invoices to your purchase document and G/L setup

Optional Peppol Access Point connection configured and tested if network delivery is in scope

Setup and admin guide plus a short handover session for your finance and IT teams

Post-go-live support window and regulatory-update maintenance under the agreed plan

Who this is for

German finance / AP-AR team

Finance staff who must receive structured B2B e-invoices from 2025 and send them as the mandate phases in, without rekeying XML or maintaining a separate invoicing tool outside Business Central.

Business Central administrator / IT lead

The person responsible for the BC tenant who needs a clean per-tenant extension, proper permission sets, Job Queue automation and an upgrade path that survives Microsoft's twice-yearly BC releases.

Finance director at a German SME or Mittelstand group

Owns compliance risk for the 2025-2028 mandate and wants a fixed-scope, supported solution with a clear delivery date rather than an open-ended internal AL project.

Frequently Asked Questions about Germany XRechnung / B2B E-Invoice for Business Central

Is this an instant download from Microsoft AppSource?

No. This is a build-to-order extension. ECOSIRE builds it in AL, installs it as a per-tenant extension on your Business Central environment, and configures it to your number series, VAT posting groups and document layouts. You are buying the build plus installation and support, not a self-service AppSource listing.

How long does delivery take after I order?

Typical delivery is around 2 to 4 weeks from kickoff, depending on whether inbound parsing and the optional Peppol Access Point are in scope and on access to your BC environment. We confirm a firm date at kickoff after a short scoping call, then build, validate against EN 16931, install on a sandbox for your sign-off, and promote to production.

What happens with ongoing support and regulatory updates?

Germany's e-invoicing rules and the XRechnung/ZUGFeRD specifications keep evolving, and Microsoft ships two major BC releases a year. Under the agreed support plan ECOSIRE keeps the extension compatible with new BC versions and updated to the current EN 16931 / XRechnung CIUS, and fixes issues you report. You also receive the source, so you are never locked in.

Does it work on both Business Central cloud (SaaS) and on-premises?

Yes. It is built with standard AL extension primitives — table/page extensions, event subscribers, permission sets and the Job Queue — so it installs as a per-tenant extension on BC online (SaaS) and on supported on-premises and private-cloud deployments. We confirm your version and deployment type during scoping.

Can the generated XML feed our own portal or other systems?

Yes. Generated invoice XML and validation status are stored on the posted document and exposed through the Business Central REST/OData API, so a customer portal, a Power Platform flow or another downstream system can pull documents and status. Dataverse surfacing for finance dashboards is available as an option.
