I Bootstrapped a Robust, Offline-First POS for the Real World. It's Doing $45k/m. Here's the Stack.
Hey Indie Hackers,
For 15 years, I've helped Fortune 500 companies with their digital marketing, but my most rewarding project has been building something tangible for the backbone of the economy: small and medium-sized retailers.
I kept seeing the same story: fantastic local shops and restaurants were being bled dry by subscription-based POS systems. $99/month/terminal adds up fast. Their internet goes down? They can't make a sale. They want a specific feature? Tough luck.
So, I decided to build Off POS.
What is Off POS?
It's a powerful, self-hosted Retail POS and Inventory Management software built in PHP (CodeIgniter), JS, and MySQL. The key differentiator? It’s a one-time purchase. You own it. Forever. No monthly fees.
This isn't a toy. It's an enterprise-grade system used by over 3,500 businesses (and counting) in over 85 countries, from coffee shops in Berlin to hardware stores in Manila.
🚀 The Problem We Solve:
Eliminating Crippling Monthly Fees: Save thousands per year.
Offline Resilience: Internet down? No problem. Sales never stop.
Complete Data Ownership: Your data lives on your server, not in a silo.
Total Customization: Since it's self-hosted, any competent PHP dev can modify it to your exact needs.
💸 The Business Model That Resonates:
We sell on CodeCanyon. It's a brutal, meritocratic marketplace. You can't hide behind a sales team. The product must stand on its own. Our success there ($45k+ in monthly revenue, a 4.82/5 star rating from nearly 900 reviews) is the ultimate validation that we're solving a real, painful problem.
🛠 The Tech Stack (For the Builders):
Backend: PHP (CodeIgniter 3) - Reliable, well-documented, and a massive talent pool.
Frontend: Bootstrap, JS, jQuery - Fast, responsive, and works on everything from modern touchscreens to old monitors.
Database: MySQL - The industry workhorse.
Reporting: Built-in advanced reports with profit analytics, sales trends, inventory valuation, and more.
Key Features: Barcode support, multi-store/-warehouse management, supplier/customer management, invoice generation, and a full accounting integration suite.
📈 Marketing & Growth:
My marketing experience was key. We didn't do ads at first.
Content & SEO: Created deep, valuable content around the problems (e.g., "how to choose a POS," "subscription POS vs one-time cost").
Social Proof: Our CodeCanyon reviews are our #1 sales driver. We engage with every single piece of feedback, publicly.
Community: We have a dedicated support forum. Users help each other, creating a powerful ecosystem and reducing support load.
Word-of-Mouth: Solving a core pain point makes customers your best evangelists. A shop owner who saves $2,000/year tells other shop owners.
This isn't just a "launch." It's a proven business. I'm sharing this here because the Indie Hackers community appreciates real-world, bootstrapped success stories that provide immense value.
I'm happy to answer any questions about:
The decision to build on CodeCanyon vs. a standalone SaaS model.
Handling support and updates for a one-time purchase product.
The technical challenges of building a reliable offline-first system.
Marketing a "boring" B2B product effectively.
If you know a retailer who's tired of the subscription grind, please share this with them. You might just save their business thousands.
