    Meteroid

    Meteroid

    Open-source pricing and billing infrastructure

    Meteroid is an open-source, cloud-native pricing and billing infrastructure designed to support usage-based billing, subscription management, invoicing, and cost-tracking — particularly for SaaS or product-led businesses that need flexible billing models beyond flat subscriptions. It provides an API-driven billing engine: you feed Meteroid usage data from your application (e.g. API calls, storage usage, seats, feature usage), define custom pricing rules or plans, and Meteroid calculates charges, generates invoices, tracks usage, and supports cost limits or quotas. The system is written in Rust, emphasizing performance, reliability, and safety, making it suitable for production use in small startups up to large enterprises. Meteroid handles complexities like plan versioning, usage-based billing, re-invoicing, grandfathering of plans, experiments, and cost limiting — giving teams a robust billing backend without building one from scratch.

    Facturitas

    Programa - web-php para gestionar facturas en base de datos mysql.

    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....
