WhatsApp Marketing, Team Inbox & Automation SaaS

Campaigns, shared inbox and chatbots on the WhatsApp Business API

A multi-tenant SaaS that lets businesses run WhatsApp marketing and support from one console: template campaigns, a shared team inbox, contact management, chatbot flows and AI-assisted replies, sold on subscription plans.

  • Laravel
  • MySQL
  • WhatsApp Business API
  • OpenAI
  • Pusher
  • Stripe
  • Razorpay
  • Docker

The challenge

Marketing and support teams wanted WhatsApp to do more than one-off messages: campaigns to segmented contacts, a shared inbox where agents can pick up chats, and automation for common questions, all inside the rules of the WhatsApp Business API.

What we built

We built and customised a Laravel SaaS where each business (vendor) gets its own workspace. Teams import and label contacts, send approved template and media messages, and work conversations in a real-time inbox with notes, labels and agent assignment. Chatbot flows and OpenAI-assisted replies handle routine questions. A central console manages vendors, branding and subscription plans with Stripe and Razorpay billing, plus marketing pages for industries and use cases.
