E-Invoicing
E-invoicing is the exchange of invoices in a structured digital format.
True e-invoicing means invoices are sent as structured data (such as XML) that the recipient's system can process automatically — not just a PDF by email. It reduces errors, speeds up payment, and is mandatory in a growing number of countries for B2B and B2G transactions. Requirements and formats vary by jurisdiction.
Example
A supplier sends an EN 16931-compliant XML invoice that posts directly into the buyer's accounting system.

Frequently asked questions
Is emailing a PDF e-invoicing?
No — a PDF is a digital image of an invoice, but it is not structured data. Real e-invoicing uses machine-readable formats so systems can validate and process the invoice without manual entry.
Where is e-invoicing mandatory?
An increasing number of countries require it — including several in the EU, Latin America, and Asia — often starting with government suppliers. Check the current rules for each country you invoice into.
