Before One-Bill, I had three spreadsheets and a prayer. Now I can see my exact profit on every sale, live. It changed how I run my store completely.

Owner, Pharmacy — Colombo
The batch tracking and expiry alerts alone saved us thousands. We used to write everything off. Now nothing slips through unnoticed. The low-stock alerts are a complete game changer.

Ayesha Thilak
Manager Supermarket — Kandy
We run 3 branches. The inter-warehouse transfer feature and the central dashboard mean I always know where my stock is — from my phone, anywhere, anytime.

Director, Silva Supermarkets
Onboarding was incredibly fast. The CSV import got all our products in within a day. Role-based access means my cashiers only see exactly what they need to. Brilliantly designed.

Nirosha Fernando
Owner, Supermarket — Negombo
The supplier portal is something I did not expect to love so much. My reps can check order status without calling me. It saves me at least an hour every single day.

We switched from a legacy system that cost double. One-Bill's reporting suite gives us more insight than we ever had. The COGS breakdown is exactly what our accountant needed.
