NexoPOS is a point-of-sale platform that runs a whole shop from the browser, covering the till, the stockroom, the customer book, and the day-end numbers in one place. Cashiers ring up sales on a touch-friendly register screen, take cash or card payments, print receipts, and process refunds without leaving the same view. Every sale draws down inventory automatically, and procurement flows record what arrived, from which supplier, and at what cost. Low-stock warnings and a full stock history help owners reorder before shelves go empty. Products carry categories, units, and tax rules, and barcode plus scale barcode support keeps weighed goods moving at the checkout. Regulars earn rewards, join customer groups, and redeem coupons at the till. Managers open and close registers, assign roles and permissions to staff, and review an activity trail for every sensitive action. Reports break down sales, costs, and stock value per period, giving a small shop the numbers usually reserved for chain headquarters. Owners extend the core with installable modules for restaurants, multiple stores, rentals, and bookings, added from inside the dashboard instead of by editing code. The same installation serves a single boutique today and a growing chain tomorrow, since registers, stores, and staff all live in one database. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.
