Questions about Invoice Builder

Is Invoice Builder free?

Manual one-at-a-time invoice, estimate, and credit note creation is free. Bulk spreadsheet generation and advanced reuse tools require Monthly or Lifetime access.

Does Invoice Builder upload invoice contents to a server?

No. Seller, customer, item, spreadsheet, and invoice contents stay in the browser by default. Generated PDF/XML/ZIP files are browser downloads you manage.

Does it support special invoice formats?

Yes. The app includes supported special invoice output paths such as XRechnung, ZUGFeRD, and Factur-X where implemented, without acting as a filing or compliance service.

Can it help when a buyer ERP rejects an invoice?

Yes. For supported cases, the buyer rejection helper can map rejection messages and inspect uploaded XML or hybrid PDF files for common structured fields before regeneration.
