Invoices via a form: extraction, validation and a weekly report

The scenario takes an uploaded invoice, extracts every field, validates it, stores it and emails a confirmation. Once a week it sends a full summary.

  • Not a single number typed by hand
  • Extraction problems are flagged immediately, by email
  • The original submission is stored in full
  • The weekly spend summary arrives on its own
