Everything you need to run your shop

From the POS screen to the admin dashboard — OS-POS has every feature your team needs, ready out of the box.

🏪

Multi-Shop Support

Run multiple independent shops from one platform. Each shop gets its own subdomain, users, products, and data — fully isolated.

🛒

Fast POS Interface

Clean, responsive POS screen built for speed. Search products, manage a cart, collect customer info, and confirm orders in seconds.

📦

Inventory Management

Track stock levels in real time. Every sale auto-deducts inventory. Get low-stock alerts before you run out.

🧾

Receipts & Invoices

Auto-generate printable receipts with customer name, phone, address, items, and totals. Built-in print support.

💳

Flexible Payments

Add Cash, Bank Transfer, PromptPay, or any payment method. Admins can reorder and toggle methods per shop.

👥

Role-Based Access

Super Admin, Admin, and Sales roles. Sales staff only see the POS. Admins manage everything. You stay in control.

📊

Reports & Analytics

Sales summaries, top-selling products, low stock reports. Get the data you need to make smart decisions.

JWT auth with 8-hour expiry, bcrypt passwords, shop-scoped data access, Zod validation, and Prisma parameterized queries.
