Vendra — POS & Inventory System (PHP + MySQL, Self-Hosted)
Self-hosted POS & inventory engineered so overselling is impossible.
The problem it solves
Retail shops, cafés, and market stalls need stock counts they can trust and profit numbers that are real — but cheap POS scripts fall apart on exactly that: counts drift, overselling happens, and margin reports become fiction because cost isn't tracked properly.
- Stock counts that drift from what's actually on the shelf
- Overselling the last unit when two cashiers ring up at once
- Profit reports that don't reflect true cost of goods
What you get
Oversell-proof checkout
Overselling is enforced at the database level, even when two cashiers sell the last unit at the same instant.
Immutable stock ledger
Every stock change — sales, purchases, returns, adjustments — posts to an auditable movement ledger with cost, reference, and who did it.
One-click ledger verification
Re-derive every stock count from the ledger and prove the numbers match.
Weighted-average costing
Drift-free integer-math costing updates on every purchase, so profit reports reflect true margins.
Barcode-ready POS screen
Fast product grid with category tabs, keyboard-wedge barcode scanning, split payments, and hold & resume sales.
Full store operations
Purchases and receiving, returns, register sessions with Z-report, and reports by product and cashier.
