ZUGFeRD parser

A ZUGFeRD parser ingests PDFs with embedded XML or standalone XML to extract structured invoice data. It normalizes fields to a consistent data model and outputs JSON suitable for ERP and accounting workflows. It identifies supplier and customer data, dates, currency, line items, taxes, and totals, providing a machine-readable representation for downstream systems.

Data integrity is maintained through validation of mandatory fields such as invoice number, issue date, and total amounts. The parser supports invoices with multiple line items and various tax rates, aggregating totals and ensuring consistency across records. An optional raw XML export preserves the original data for audit and compliance checks.

Designed for developers, AP teams, and ERP integrators, the tool enables automation of data capture from electronic invoices. By producing a uniform schema, it simplifies integration with ERP, BI, and workflow platforms, reduces manual entry, and mitigates human error. It also provides structured error information to guide remediation.

While focused on data extraction rather than UI, the parser emphasizes interoperability and traceability. It supports EU e-invoicing standards and XRechnung mappings where applicable, and it can be extended to additional currencies and locales in enterprise deployments.
