# E-invoicing

> Send and receive structured electronic invoices through PEPPOL and other e-invoicing networks using the Tesouro API.

## Overview

***E-invoicing***, also known as ***electronic invoicing***, is the process of generating, transmitting, and receiving invoices in a structured electronic format rather than paper-based or PDF documents. E-invoicing streamlines the invoicing process by eliminating the need for manual data entry. This reduces errors and improves the accuracy and efficiency of billing and payment processes.

Tesouro integrates with multiple e-invoicing partners to provide a global e-invoicing solution and help our partners send and receive e-invoices using the Tesouro API. This integration enables Tesouro clients to stay compliant in the regions where e-invoicing becomes mandatory.
