Technical e-invoice integration
PDF to e-invoice: what is technically possible
A PDF is not automatically a structured e-invoice. Assess whether data can be extracted, completed, validated and output under control.
PDF is only the starting point
A PDF-to-e-invoice workflow must first distinguish structured source data from values that need extraction. OCR and parsers can suggest values, but do not replace review.
Control quality
Line items, tax rates, totals, addresses and references need comparison with the source. Ambiguous cases need a visible human approval step.
Make it repeatable
For recurring invoices, a stable export or data access is usually more robust than manual one-off uploads. Target handover and error feedback belong in the design.
Use the Compatibility Check
Describe the current PDF process and available exports to narrow down the technical route.
Plan human review
When values are extracted from PDFs, the system should show uncertainty and avoid silent corrections. A reviewer confirms or corrects data before a structured record is handed over.
Estimate effort realistically
Assess examples with different layouts, languages, suppliers and scan quality. This reveals whether a parser, OCR, source data or a combination is economically sensible.
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.
