NTPOS Wholesale
Multi-tenant wholesale POS with inventory, invoicing, and khata ledgers so shops can run stock and credit from the browser instead of a single till PC.

Overview
NTPOS Wholesale is a multi-tenant suite for distributors and kiryana-style wholesale counters: invoicing, stock, and khata in the browser. Shops log in over JWT, run on PostgreSQL, and keep credit customers on a ledger instead of a notebook.
Challenge
Wholesale counters mix cash, credit, and bulk SKUs. Desktop POS installs break when the PC changes, and owners cannot see stock across branches without calling the shop.
Solution
An Express + PostgreSQL service with JWT auth, shop tenancy, inventory movements, and khata. Operators work from any browser. Stock and credit are first-class, not plugins bolted onto a retail till.
What we built
- Multi-shop tenancy with JWT sessions
- Wholesale invoicing and SKU catalog
- Inventory quantities with stock movements
- Khata / market-credit ledgers per customer
- Browser POS so the counter is not bound to one PC
Outcomes
- Stock and credit visible without a shop-floor PC
- Tenants isolated while sharing one platform
- Khata stays attached to the same invoice trail
Stack
