Se trata de un programa con interfaz web y motor php para gestionar facturas, almacenándolas en una base de datos mysql. Utiliza la clase FPDF para generar el PDF de las facturas y así poder imprimirlas. De momento está hecho con código "basura", muy sucio, mucho copy/paste y nada organizado. Es una versión "prototipo" para mejorar y añadirle funciones. La idea es hacer un programa SIMPLE, para el autónomo y la pequeña empresa, que no necesite más que la simple gestión de: clientes, servicios, productos y facturas, de una forma sencilla y práctica. Actualmente funciona, pero no se recomienda para uso en producción, ya que puede tener fallos. Espero que poco a poco vaya mejorando. Cualquiera puede colaborar. Es mi primer proyecto open source, así que no tengo ni idea de como funciona esto. Espero ir aprendiendo. Ver el archivo readme.txt (en Browse All Files) para instrucciones de instalación....
