Electronic Invoicing – Costa Rica

Implementing electronic invoicing in Costa Rica involves working with strict technical standards: generating XML under specific structures, digitally signing it with a certificate, and sending it to tax authority services while complying with multiple validations.

As with other countries, one of the main challenges is XML generation. It is a large, rigid format with many rules, making it difficult to manage directly and prone to errors without proper abstraction.

This package, built in PHP, was created to simplify that entire process. Instead of manually building the XML, the developer defines the invoice using a clean and easy-to-understand array. From that input, the package handles XML generation, digital signing, and submission to the corresponding authority.

The goal is to abstract the technical complexity behind a simple interface, allowing developers to focus on business logic rather than implementation details of the standard.

This project is part of a broader set of solutions focused on electronic invoicing in Latin America, built from real-world experience and designed to be reusable and easy to integrate.
