Platform Features

Everything your retail business needs, in one place.

From barcode to balance sheet — OneBill connects every part of your operation with intelligence and precision.

Smart POS Engine
Barcode-driven scanning handles multiple batches and variants instantly. Real-time tax, discount, and profit calculations keep every cart accurate. Supports Cash and Credit sales with automated due tracking and a modern, responsive interface built for speed on the shop floor.
Multi-Batch Inventory
Track by Batch Number, Expiry Date, and unit cost. Manage nested product variations — sizes, forms, weights — under a single parent item without any complexity.
Purchase Orders & GRN
Generate professional POs with PDF export. A dedicated supplier portal lets vendors view orders directly. Handle free items and auto-deduct pending returns at settlement.
Returns & Settlement
Purchase returns instantly reduce stock and link to future GRNs for seamless bookkeeping. Sales returns restock inventory and adjust revenue in real time.
Business Intelligence
Revenue, COGS, and net profit reports. Top-selling product analytics, salesperson performance rankings, SMS audit trails, and full user activity logs.
Warehouse Transfers
Move stock between locations with status-based confirmation — Pending to Sent — with full visibility and real-time cost-to-retail valuation across all warehouses.
Role-Based Access
Granular permissions for Admins, Managers, and Staff. Every action is logged — who did what and when — so your data stays secure and your team stays accountable.
Low Stock Alerts
Intelligent monitoring with customizable thresholds per variation. Automated SMS reminders keep your team ahead of shortages before they impact sales.

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

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.

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.

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.

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. OneBill's reporting suite gives us more insight than we ever had. The COGS breakdown is exactly what our accountant needed.
