E-Invoice: The future of invoicing is here
Introduction: What is E-Invoice?
The E-Invoice, also known as an electronic invoice, is a tax document that has revolutionized the way companies manage their business transactions. In contrast to traditional invoices printed on paper, the E-Invoice is issued, transmitted and archived in digital format, using electronic means such as email, specialized web portals or electronic invoicing systems.
This electronic invoicing format has been adopted by numerous countries around the world as part of their modernization and administrative simplification strategies. Its use not only reduces paper consumption and the costs associated with printing and physically sending invoices, but also streamlines business processes and improves administrative efficiency.

How E-Invoice works

- Signature of the electronic invoice:
- The company issuing the invoice must sign the electronic invoice with an electronic certificate.
- This electronic certificate identifies the company digitally and guarantees the authenticity and integrity of the invoice.
- Sending the electronic invoice:
- The invoice company must send the electronic invoice to its customer through a secure channel.
- This secure channel can be email, a web portal, or an electronic data interchange (EDI) system.
- Receipt of the electronic invoice:
- The customer can receive the electronic invoice in their email or through a web portal.
- If the customer receives the e-invoice in their email, they must download it and store it in a safe place.
- If the customer receives the electronic invoice through a web portal, they must access the web portal with their access codes and download the invoice.
- Storage of the electronic invoice:
- Both the issuing company and the customer must store the electronic invoice for the legally established period.
