Solo Solution Architect vs. Agency Bloat
Compare direct engineering ownership with typical software agencies:
| Dimension | Abin S Chandran (Direct) | Traditional Regional Agency | Off-The-Shelf SaaS |
|---|---|---|---|
| Direct Communication | 1:1 Direct with Senior Architect | Filtered via non-technical account managers | Impersonal chatbot ticket queues |
| Code & IP Ownership | 100% Full IP & Git repo handover | Often locked in proprietary agency modules | 0% ownership (Vendor locked in forever) |
| Monthly License Fees | ₹0/month (Fixed one-time build) | Expensive monthly retainer contracts | ₹2,500–₹8,000/seat/month recurring tax |
| Turnaround Speed | 2 to 4 weeks production MVP | 3 to 6 months with endless change orders | Days to set up, but rigid & unadaptable |

Frequently Asked Questions
Why choose a custom Next.js e-commerce store over Shopify or WooCommerce?+
Shopify charges 2–3% transaction fees plus hundreds of dollars in monthly app fees, while WooCommerce suffers from severe database bloat, plugin vulnerabilities, and slow checkout speeds. A bespoke Next.js 15 headless store loads in under 800ms, gives you 0% platform transaction fees, runs on your own database, and converts significantly higher.
Which payment gateways are supported for Indian and international customers?+
We integrate Razorpay and Cashfree for Indian domestic cards and UPI, alongside Stripe and PayPal for seamless international USD/EUR/AED payments.
Can our store handle high-traffic festival sales (e.g. Onam / Vishu / Diwali flash sales)?+
Yes. Our headless architecture scales automatically on edge serverless networks and Redis queues, easily handling 10,000+ concurrent shoppers without slowdowns or server crashes.
