Electronic Invoice: What It Is and How to Generate It Easily

The electronic invoice has become a fundamental tool for companies and freelancers throughout Latin America. More than a technological trend, it is a legal reality that is transforming the way we manage our business finances.

If you haven’t yet migrated to digital invoicing or have questions about how to create an electronic invoice, this guide will give you all the information needed to make the leap definitively.

What is an electronic invoice?

An electronic invoice is a digital document that meets the same legal and tax requirements as a paper invoice, but is generated, transmitted, and stored exclusively by electronic means.

Don’t confuse an electronic invoice with a PDF of a traditional invoice. The electronic invoice has specific characteristics:

Element	Description
Structured format:	Uses standards like XML or UBL
digital signature:	Guarantees authenticity and integrity
Complete traceability:	From creation to archiving
Automatic validation:	Data is verified against official databases

Important fact:

According to CEPAL, 78% of B2B transactions in Latin America will mandatorily use electronic invoicing by 2025.
