Most subscription tools are complex, overpriced, and ignore how small businesses actually operate.
In Pakistan and across emerging markets, businesses manage subscriptions through WhatsApp. Not emails. Not portals. WhatsApp.
So I built a complete frontend system around that exact workflow.
Why I Built This
While working as a Frontend Engineering Intern at Peham LTD, I kept noticing the same gap: businesses needed a clean way to manage subscriptions tied to WhatsApp-based communication workflows.
Existing SaaS dashboards are built for enterprise. They assume complex CRMs, payment APIs, and dedicated ops teams.
But a local gym, a newsletter creator, or a service business running on WhatsApp? They need something simpler — and more focused.
I wanted to build a real SaaS-style product that solved this specific problem. A system with a proper landing page, an admin dashboard, and a workflow that maps to how these businesses actually communicate with their users.
What I Built
WhatsApp Subscription Management System — a complete frontend SaaS application with two core parts:
🏠 Landing Page
- Clean, conversion-focused hero section
- Feature highlights explaining the WhatsApp-first workflow
- Pricing section
- Call-to-action flows
- Fully responsive across all screen sizes
📊 Admin Dashboard
- Subscription overview and stats
- Subscriber list with status management (active, paused, cancelled)
- WhatsApp message workflow triggers
- Clean UI with intuitive navigation
- Mobile-responsive layout
Tech Stack
- React.js — component-based architecture
- Modern CSS — responsive, utility-first styling
- React Router — client-side navigation between landing and dashboard
- Component composition — reusable UI elements across views
- Vercel — deployed and live

How I Built It — The Breakdown
- Landing Page Architecture The landing page was designed as a standalone marketing surface. I separated it from the dashboard routing intentionally — different goals, different component trees.
Key sections:
- HeroSection — above-the-fold hook with CTA
- FeaturesGrid — card-based feature breakdown
- Pricing Section — tiered plan layout
- Footer — links and brand close
Each section is a standalone component. Easy to update independently without touching unrelated UI.
2. Admin Dashboard Structure
The dashboard follows a classic SaaS layout pattern:
Fixed sidebar with navigation
Top bar with context and user info
Main content area with dynamic views
I built the subscriber management table as a controlled component with local state, cleanly handling status filters, row actions, and empty states.
3. WhatsApp Workflow UI
This is the most unique part of the system. Instead of generic "send email" buttons, the workflow UI is built around WhatsApp actions — message triggers tied to subscription lifecycle events (onboarding, renewal reminder, cancellation confirmation).
Each trigger maps to a clear UI state. No backend yet — but the frontend is structured to plug into a WhatsApp API layer (like Twilio or Meta's Cloud API) without a rebuild.
4. Responsive Design Strategy
I used a mobile-first approach throughout:
Sidebar collapses to a hamburger on mobile
The subscriber table becomes a card list on smaller screens
Landing page sections stack cleanly on all breakpoints
No UI library — custom responsive components. More control, less bloat.
Result & What I Learned:
The system is live and fully functional as a frontend application.
What I got out of this build:
✅ Deeper understanding of SaaS dashboard architecture in React
✅ Cleaner thinking about component separation and responsibility
✅ Hands-on experience designing around real-world workflows (not textbook features)
✅ Confidence in building landing page + dashboard as one cohesive product
The biggest shift was thinking like a product engineer rather than just a UI developer. Every component decision is tied back to: Does this serve the user's actual workflow?
Final Thoughts:
Frontend engineering isn't just about shipping UI — it's about building systems that fit how people actually work.
This project pushed me to design around a specific, real use case. Not a generic CRUD app. A product that understands its users communicate through WhatsApp, not email, and builds the entire experience around that.
That kind of thinking — workflow-first, not feature-first — is what I want to carry into every project I build at Hashir WebX Studio.

Should I break down the WhatsApp workflow architecture in a dedicated post?
