Germany XRechnung / B2B E-Invoice for Business Central

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.

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.

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.

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.

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.
