> Genera expresiones de CFDI 4.0, CFDI 3.3, CFDI 3.2, RET 1.0 y RET 2.0

🇺🇸 The documentation of this project is in spanish as this is the natural language for intended audience.

🇲🇽 La documentación del proyecto está en español porque ese es el lenguaje principal de los usuarios.

Esta librería contiene objetos de ayuda para crear expresiones de CFDI 3.2, CFDI 3.3, CFDI 4.0, RET 1.0 y RET 2.0 de acuerdo a la información técnica del SAT en el Anexo 20.

Estas expresiones se utilizan principalmente para dos motivos:

1. Generar el código QR de una representación impresa de un CFDI o RET.
2. Consultar el WebService del SAT de estado de un CFDI.

Ejemplo de expresión para CFDI 3.3 y CFDI 4.0:

Estas especificaciones comparten el mismo estándar.
