The journey
From idea to launch, in four chapters
Scroll through the story every OpenSoz project follows — the same chapters whether it is a 48-hour website or a 10-day app.
Chapter 02 · Design
Designed before it is built
Layout, colours, flow and words come first. You approve a preview, so the build that follows is the one you already liked.
Chapter 03 · Build
Built fast, in the open
React, Next.js, Flutter and modern backends — assembled quickly, tested as we go, and shared with you while it takes shape.
Chapter 04 · Launch
Launched — and supported
Live on your domain, with payments, WhatsApp and analytics wired in. Then support, updates and the next version.

Why OpenSoz
Faster and more transparent than a typical agency
| What matters | OpenSoz | Typical agency |
|---|---|---|
| Speed | 48h / 7-day / 10-day delivery windows | Weeks to months, often open-ended |
| Pricing | Custom quote after free review — no hidden fixed-price surprises | Vague estimates, add-on charges |
| Indian payments & GST | UPI, WhatsApp and GST know-how built in | Often an afterthought |
| Support | support@opensoz.com, 24-hour reply target | Ticket queues, slow replies |

What customers say
Sample content — to be replaced with real customer testimonials.

“Review replies used to sit for days. Now every review gets a polite reply in the customer's own language, and our rating is climbing.”
“The website was live in two days, exactly as promised, and it already brings enquiries from Google.”
