I Built a Restaurant POS SaaS in India — Here’s What Nobody Tells You

When I started building RestroQT, I thought I was building a simple restaurant billing system.

I was wrong.

What I ended up building is a full SaaS platform for restaurants and hotels — handling billing, GST, QR ordering, kitchen display systems, UPI payments, and financial reporting.

And along the way, I learned a few things nobody really tells you before building SaaS in this space.

🧠 It’s not a “POS problem”, it’s a “chaos management problem”

Restaurants don’t want software.

They want:

No billing delays
No GST mistakes
No kitchen confusion
No staff training headache

POS is just the surface. The real problem is operational chaos.

🇮🇳 India makes it harder (and more interesting)

Building for Indian restaurants adds layers:

GST billing rules everywhere
UPI payments expected by default
Internet can be unstable
Staff often not tech-savvy
Multi-language UI needs matter

Most global POS systems don’t solve this well.

⚙️ Tech stack I used

RestroQT is built using:

Backend: FastAPI
Frontend: React
Database: MySQL
Server: Single VPS (yes, one machine)
Nginx for routing and deployment

For reliability, we use automated database backups with off-server storage and separate secure environments for higher-tier (PRO) clients to ensure data isolation and safety.

I intentionally kept the infrastructure simple at the start using a single VPS to focus on product development and real user feedback.

🧩 Multi-tenant SaaS is harder than it looks

The biggest challenge wasn’t UI or payments.

It was:

Data isolation between restaurants
Role-based access (owner, cashier, waiter)
Real-time updates for orders
Kitchen display synchronization

One bug in tenant logic = catastrophic data leak risk.

🔥 QR ordering changed everything

One feature changed how users interacted with the system:

👉 QR-based ordering without login

Customers scan → order → pay

No signup friction.

This alone improved adoption significantly.

💡 What I learned building this

Start simple — complexity comes naturally later
Real users break your assumptions fast
Restaurant software is about speed, not features
UX matters more than backend architecture
Indian market needs very specific solutions

🚧 What I would do differently

Build billing engine before adding features
Focus on one restaurant type first
Add analytics earlier
Avoid overengineering backend at start

🌐 Where it is now

RestroQT is currently live and evolving.

It is being shaped based on real restaurant feedback.

🚀 Final thought

Building SaaS is not about writing code.

It’s about surviving real-world complexity long enough until your system becomes stable.

If you're building something similar, I’d love to connect and exchange ideas.
