POS 2.0 Retail ERP
A working multi-store web point-of-sale (POS) and ERP, built from scratch as a systems-design showcase.
01 · The opportunity
What it set out to solve
Multi-store retail is genuinely hard to run well. Stock sits in separate silos, transfers between locations are manual, and GST rules for consignment goods are fiddly to keep consistent in spreadsheets. I wanted to design what an ideal modern, central web POS and ERP could look like.
02 · The approach
How I thought about it
I treated it as a systems-design problem: what should an ideal POS and ERP feel like for a cashier, a store manager and a founder at once? I mapped the end-to-end retail workflow and built it as a central web app with clean roles and a live stock model.
03 · What I built
- Billing with multi-tender payments and 80mm receipt printing
- GST margin scheme (Rule 32(5)) support for consignment stock
- Live stock-on-hand across multiple store and warehouse locations
- Sell-returns, credit notes and inter-location transfers
- Day-end reports and a consignment settlement view
- Role-based access for cashiers, managers and admins
04 · The result
What changed
A working web POS and ERP, verified end to end — proof of the operational systems I can design and build.
