Fiscal cash register and stock control for retail
Harmony is a program for retail shops that runs as a fiscal cash register in line with Serbian e-fiscalization, working as an ESIR connected to the LPFR processor. Each sale prints a valid fiscal receipt.
Scan barcodes at checkout, track stock in real time, and get low-stock alerts before you run out. Prices, discounts, and promotions apply automatically.
Loyalty, sales reports, and stock counts sit in one place, so you know what sells and what to reorder.
