ZUGFeRD PDF Generator

E-InvoicingLive

On 1st of January 2027, it will become mandatory for suppliers above 800.000€ annual turnover to create EN16931 compliant e-invoices and send them to their customers. ZUGFeRD PDF is one of the recommeded formats here. With this tool AR clerks can easily generate a compliant ZUGFeRD PDF incl. a validation report and even send it via email to their customers. I also build a valdiation tool where AP clerks can upload a ZUGFeRD PDF and proof if it is legally compliant with the ZUGFeRD specs. They can download a validation report as well. Disclaimer: This is not a Basware product. I built this as a private side project.

From Specs to Live

Providing all the specs for latest ZUGFeRD 2.5 to Claude Code and let it just build this tool was really simple. Especially when specs are cristal clear, AI vibe coding tools do a fantastic job.
