A Point of Sale (POS) management system runs the checkout for a shop: it scans products, records sales, manages customers and suppliers, and reports on the day’s takings — all while keeping stock accurate. This version adds barcode scanning and low-stock highlighting.
Features
- Barcode scanning during sales
- Add, edit and delete products, customers and suppliers
- Low-stock highlighting when a product falls below a threshold
- Daily, monthly and yearly reports
- Printable transactions
The key concept: transactions and stock
Every sale must record the sale, its line items, and reduce stock — all or nothing. Database transactions guarantee that, and a POS is the clearest example of why they exist. Low-stock highlighting then turns live stock data into a reorder prompt.
Technology stack
PHP with MySQL; barcode scanners act as keyboards, so no special drivers are needed. Bootstrap gives the cashier a clean, fast screen.
What you’ll learn
Atomic transactions, real-time stock accounting, barcode input handling, and time-aggregated sales reports.
Frequently asked questions
Do barcode scanners need special code?
No — most behave like a keyboard that types the code and presses Enter into your product-lookup field.
How does low-stock highlighting work?
Compare each product’s quantity to a reorder threshold and flag the row when it drops below it.
A note on using this project
Use this PHP/MySQL project as a learning reference: read the code, run it locally, and adapt it to your own requirements rather than deploying it unchanged. If you reuse third-party components, check their licences first.
