B2B e-invoicing in Andorra
There is no mandate for e-invoicing relating to business-to-business (B2B) transactions.
Sellers can voluntarily choose to issue invoices electronically, provided they obtain the buyer’s explicit permission beforehand. There is no set format or e-signature requirement for this voluntary activity. If they choose to issue e-invoices, the issuer must ensure the integrity of the content and the authenticity of the origin by using, for example, an electronic signature.
