03 / E-invoicing

Integrate e-invoicing into existing Access workflows

An established Access invoicing application does not necessarily need to be replaced. I help extend its processes for structured electronic invoices.

Typical questions

  • Invoices currently originate in Access, Word or PDF.
  • Existing customer data and invoice numbers must remain usable.
  • ZUGFeRD or XRechnung is required.
  • Validation, output, storage and dispatch need to work together.

Possible components

  • Analyze existing invoicing data and VBA code
  • Adapt reports and PDF output
  • Integrate structured data for ZUGFeRD and potentially XRechnung
  • Add validation, dispatch and error handling

Technologies and practical experience

  • Extending existing Access invoicing workflows to support structured electronic invoice data.
  • ZUGFeRD, XRechnung, PDF output, validation and delivery processes as potential integration components.
  • The referenced e-invoicing work is ongoing and is not presented as a completed delivery.
Ongoing work: Retail and industry association

Electronic invoicing is currently being implemented in existing Access applications. ZUGFeRD work is ongoing; XRechnung is another relevant requirement, not a claimed completed delivery.
