Smart Lead Tech’s multi-tenant WhatsApp platform: QR-paired sessions, a public API with a key per session, bulk campaigns from Excel, webhooks and subscription plans — bundled with any app you buy from us, so you never need a third-party WhatsApp provider.
SLT WhatsApp Suite is the third generation of the WhatsApp infrastructure built by Smart Lead Tech. The story began in 2024 with a Python bot that read an Excel sheet and messaged customers one by one; it grew into a multi-tenant sending platform we ran for the Arheb invitations product at whatsapp.arheb.net; today it is a standalone product embedded in every app we deliver: point of sale, salons, HR, delivery, bookings and stores.
When you buy an app from Smart Lead Tech, the WhatsApp channel comes in the package. No subscription with an outside provider, no foreign APIs to integrate, no vague extra invoice. OTPs, booking confirmations, invoices, shipping notifications and marketing campaigns — all from the same system, with one log and one support line.
It powers Arheb invitations and RSVPs, Passengers Management tickets, Cash Salon reminders, and order notifications in Waselly and Massafat — and it is the default channel for every new project we build.
Next.js for the dashboard, NestJS for the API with JWT and quotas, a background worker on Baileys and BullMQ, PostgreSQL and Redis, and Docker containers on a VPS with full CI before every deploy.
What powers this product — the core frameworks and the full stack behind it.
A digital marketplace connecting clients with freelance home beauty providers (makeup artists and more) — women-only audience, Saudi Arabia first: mobile app, web and admin dashboard with booking, payments, chat and QR check-in.
