It's not us saying it. The official validators do.

Read and check the European e-invoice

Every country solved it its own way. Anyone buying abroad ends up with five different viewers — or none. And from 2027, every Spanish invoice will also arrive with a QR code nobody checks against the paper.

We read and we check. We are not the platform your country requires you to receive them through —PDP in France, SdI in Italy, FACe in Spain— nor do we validate the electronic signature.

Who's behind this

We're not a tax software startup. We're the customer who got fed up.

PAPYR lo construye AIM, la división de software de Biomag: una empresa europea con marcas propias en el mercado y años enviando producto. No es un visor de PDF con una capa de IA encima — es ingeniería que ya opera en producción, aplicada a un problema que acaba de llegar.

Lo construimos porque cada país europeo resolvió la factura electrónica por su cuenta, y un visor te enseña el documento pero no te dice si las cuentas cuadran ni si el QR dice lo mismo que el papel. Leer el XML lo resuelve: es exacto, es instantáneo y no depende de ningún ERP.
