Behind the scenes, how we built a WhatsApp marketing SaaS from scratch 🧵
Most clients come with the same problem They have a strong idea, they need it built fast, and they do not want to rebuild it a few months later
Here is how I approached Wapzly, a multi tenant WhatsApp marketing platform
Week 1: Architecture first Before writing code, I mapped out multi tenant structure, Meta Business API flow, and billing logic. These early decisions saved a lot of rework later
Week 2 to 3: Core engine Built the bulk messaging system, automation flow builder, and shared team inbox. Laravel backend, queue workers for scale, live updates using WebSockets
Week 4: The layer most developers skip Contact CRM, segmentation, message templates, analytics. This is what makes a SaaS useful long term, not just functional
Week 5: Ship it Subscription billing, team management with roles, full authentication system, deployment, and client onboarding
Result A production ready SaaS with real paying users
