Actualmente tengo mi propia aplicación de facturación electrónica escrita en PHP. Quiero que cumpla plenamente con la normativa española y, lo más importante, que se conecte exclusivamente a la plataforma VERIFACTU para la validación de facturas antes de enviarlas a mis clientes o a la AEAT. La tarea consiste en: Incorporar al núcleo de mi sistema un módulo PHP que envíe cada factura a la API de VERIFACTU, reciba la respuesta de validación y actualice el estado del documento. Ajustar los formatos de las facturas (XML Facturae / JSON) según sea necesario para que pasen la validación sin errores. Proporcionar pruebas unitarias y de integración que muestren el flujo de trabajo completo. Entregar un breve manual de instalación y usuario para que mi equipo pueda implementar los cambios en producción. Proporcionaré acceso al repositorio Git, una base de datos de pruebas y las credenciales del entorno de pruebas de VERIFACTU. El trabajo debe realizarse 100 % en PHP, respetando la arquitectura existente y sin añadir nuevos frameworks que alteren la estructura del proyecto. Si tienes experiencia previa integrando plataformas de facturación españolas o manejando la especificación Facturae desde PHP, estaré encantado de trabajar contigo y revisar tus propuestas.

Hello, I will add a PHP module to your invoicing system that sends each invoice to VERIFACTU, waits for the validation response and updates the invoice status so the whole flow stays automatic and reliable. I will adjust your XML Facturae or JSON formats so they pass VERIFACTU checks without errors, and I will keep everything inside your current architecture with no extra frameworks. I will write clear unit and integration tests so you can see the full process working end to end, and I will prepare a short guide so your team can install and use the update in production. Looking forward to discussing further. Best Regards, Kamran.

Hello, I have delivered PHP integrations for Spanish e-invoicing and Facturae workflows, including native modules that validate invoices against third-party services. This project interests me because it requires precise VERIFACTU validation while preserving your existing architecture and avoiding new frameworks. I will implement a native PHP module that formats invoices to the required XML/JSON schemas, submits them to the VERIFACTU API, parses validation responses, updates document states, and includes unit and integration tests to demonstrate the full workflow.
