Technical e-invoice integration
E-invoice integration for a legacy ERP
A legacy ERP does not automatically require replacement. First assess data access, export options, volume and the target handover.
Keep the ERP and extend the edge
A legacy ERP can be extended with an adapter, export service or small integration layer. Data access, interface rights and ownership are central.
Volume and operations
A controlled export may be enough for low volume; higher volume makes monitoring, retries and status feedback more important.
It is more than a format
A technical solution also includes test cases, approvals, archiving, error handling and feedback into the existing team.
Next step
The Compatibility Check captures system, format, volume, recipients, exports and target requirements as a useful starting point.
Access and ownership
Establish early whether database access, export rights, documentation and a test environment exist. Also name who handles errors in the legacy ERP, integration layer and accounting workflow.
Start with controlled risk
A limited pilot using representative invoices reveals data gaps and operational effort. Expand to more invoice types or volume only after checking output, feedback and repeatability.
Questions before fixed pricing
A credible technical assessment benefits from an anonymised example, the current process description, data format, recipient groups, monthly volume and available exports. We separate technical work packages from open business or legal questions.
Result of the technical assessment
The assessment names a likely integration route, missing capabilities, data-quality and operational risks, and the next tests. Implementation starts only after scope, ownership and a fixed-price proposal are agreed.
Keep your existing ERP
Send one sample invoice or process description. We assess a technical integration route for XRechnung or ZUGFeRD without promising legal compliance.
