Hola, ¿qué tal? Estoy interesado en desarrollar una aplicación web que permita automatizar la comunicación con clientes a través de WhatsApp Business, y centralizar su gestión en un panel tipo CRM simple. La idea es contar con una plataforma desde la cual corredoras de propiedades (o asesores comerciales) puedan: ⸻ Funcionalidades requeridas • Completar un formulario de ingreso para registrar potenciales clientes (leads) • Enviar automáticamente mensajes de WhatsApp al registrarlos (usando plantillas de la API oficial de WhatsApp Business) • Recibir respuestas y clasificarlas automáticamente en etapas (Ej: interesado, no interesado, contactar más adelante, etc.) • Visualizar todos los leads desde un panel web con: • Estado de cada lead • Fecha de creación y fecha de respuesta • Teléfonos asociados (posibilidad de varios por cliente) • Filtro por comuna, condominio, dirección, estado de respuesta • Ordenamiento por columnas • Opción de descargar los registros en Excel • Panel de administración con login (usuario y contraseña) • Posibilidad de que más de un usuario pueda ingresar (multiusuario básico) ⸻ Requisitos técnicos generales • Backend en Python (preferiblemente con Flask u otro framework ligero) • Panel web responsive y funcional • Alojamiento en alguna plataforma tipo Railway, Render o similar (cloud hosting) • Integración con WhatsApp Business API (ya tengo cuenta en Meta y número aprobado) • Uso de plantillas de WhatsApp para envío inicial y reapertura de conversaciones • Considerar que la aplicación debe estar pensada para ser escalable en el futuro (más etapas, estadísticas, etc.) ⸻ Contexto de uso Esta plataforma será utilizada por corredoras de propiedades para registrar leads, enviar mensajes de contacto y hacer seguimiento desde un mismo lugar. Además de facilitar la comunicación inicial, queremos que sirva como herramienta de control para la empresa, que les permita saber cuántos leads se han gestionado, en qué estado están, y cuándo respondieron. ⸻ ¿Qué necesito ahora? Solicito una cotización estimada por el desarrollo completo de esta aplicación (versión inicial funcional), incluyendo: • Desarrollo backend y frontend • Integración con WhatsApp Business API • Panel de gestión • Hosting e implementación • Configuración inicial y despliegue

Hello, I’ll develop your WhatsApp Business–powered lead management application as a lightweight but scalable web CRM tailored for real estate workflows. The backend will be built in Python (Flask or FastAPI), with a responsive dashboard where agents can register leads, trigger WhatsApp template messages instantly, and track responses that are auto-classified into stages (interested, not interested, contact later, etc.). The web panel will display leads with filtering (commune, condo, address, response status), sorting, Excel export, and multi-user login. On the technical side, the app will integrate directly with your approved WhatsApp Business API account, support template messaging for initial/reopen contacts, and be deployed on a modern cloud service like Railway or Render for reliability. Questions: – Should the multi-user system support only basic role separation (admin vs. agent), or do you want a more granular permission model from the start? – For Excel export, do you want a one-click download of all visible filtered data, or scheduled reports sent via email? – Do you expect future features like dashboards with statistics (conversion rates, lead response times), or should we keep this first release limited to lead management only? I am a TOP Rated Freelancer, and you can check my reviews here as well: https://www.freelancer.com/u/kamran2012 Looking forward to potentially working together on this project. Thanks and Best regards, Kamran.

Hola, un gusto saludarte. He trabajado en proyectos muy similares y puedo desarrollar esta aplicación web que conecte la gestión de leads con la API oficial de WhatsApp Business y ofrezca un panel tipo CRM sencillo pero potente. La idea es implementar un backend en Python con Flask, conectado directamente a tu cuenta de WhatsApp Business para automatizar los mensajes iniciales y dar seguimiento según la respuesta del cliente. Sobre esa base construiré un panel web responsive donde podrás registrar leads, ver estados, filtrar por distintos criterios, ordenar columnas, asociar varios teléfonos y descargar la información en Excel. También incluirá login seguro con opción multiusuario para que varios asesores puedan trabajar en paralelo. El despliegue lo realizaré en una plataforma cloud ligera como Railway o Render, asegurando que quede lista para escalar en el futuro con nuevas métricas o etapas adicionales. Te entregaré una versión inicial completamente funcional y lista para usar.

I think the most important part of this project is building a fully automated WhatsApp-first CRM that allows brokers and sales teams to register leads, trigger templated WhatsApp messages instantly, and manage the entire conversation flow from a simple, centralized dashboard. The goal is to replicate the communication and tracking workflows that brokers need daily, but with a robust, scalable, and user-friendly web application that eliminates manual follow-up and ensures no lead falls through the cracks. To accomplish this, I will develop a backend in Python (Flask or FastAPI) connected to the WhatsApp Business API for sending and receiving messages. A secure web panel will let users register leads, classify replies automatically (interested, not interested, follow up later, etc.), and manage multiple phone numbers per client. The panel will also include filters by location or status, sortable columns, export to Excel, and a login system with support for multiple users. I’ll ensure the solution is robust and scalable, with proper error handling, clean UI/UX, and deployment on cloud hosting (Railway, Render, or Azure). I’ll also document the setup so you or your team can manage, extend, or scale the platform in the future. I’ll deliver a production-ready WhatsApp CRM that automates lead contact, centralizes responses, and gives your team a clear view of every client’s status — saving time and creating a streamlined sales workflow.
