There is a new regulation in Europe that mandates a defined XML-format for e-invoices for some transactions and - I kid you not - their SAP implementation wasn't able to address this. They also said that all solutions on the market were either cumbersome (think: manually typing in all fields) or required deep system integration.

I thought it cannot be that hard to use AI for this and built a little invoice converter that takes your PDF invoice in whatever form it is, and outputs exactly the XML structure that is required in the regulation. Given that AI is not perfect (but surprisingly close to it!), you can manually edit all fields.

Target users are companies where their current solution does not yet support the standard and that do not want to change their existing invoicing flow (incl. foreign businesses).

Trying it out is free. Given this is my first real B2B tool, would love some feedback!","time":1734385971,"title":"Show HN: Convert PDF invoices to e-invoice XML using AI in seconds","type":"story","url":"https://www.invoice-converter.com/en"}]]
