InvoiceOracle - 10 e-invoicing tools: XRechnung, ZUGFeRD, Peppol, validation, archive.
Scored across 10 tools
Several tools overlap in purpose: invoice_from_url, invoice_batch_urls, and invoice_summary all perform 'complete invoice analysis' with different input/output shapes. invoice_extract and invoice_summary both extract fields, and invoice_ocr vs invoice_parse_text vs invoice_tables all deal with extracting content from PDFs, though with different focuses.
Most tools follow a consistent invoice_<verb> pattern (invoice_extract, invoice_validate, invoice_summary, invoice_parse_text, invoice_tables, invoice_zugferd, invoice_from_url, invoice_batch_urls). The only outlier is health_check, which doesn't follow the invoice_ prefix but is a standard server health endpoint.
10 tools is a reasonable count for an invoice processing server. Each tool covers a distinct aspect of invoice analysis (OCR, text extraction, table extraction, validation, ZUGFeRD parsing, batch processing), though some could be consolidated.
The server covers the full invoice analysis lifecycle: input (URL, batch, OCR), extraction (fields, tables, text), validation (ZUGFeRD, §14 UStG), and summary. Minor gaps include no explicit tool for handling uploaded files (only URLs) and no tool for comparing or reconciling multiple invoices, but the core domain is well covered.
