The story
Hearthline's in-store POS, warehouse system, and e-commerce platform each tracked inventory independently, which meant customers regularly ordered items online that were already sold out in the store that was meant to fulfill them.
We built a central inventory service that every channel reads from and writes to in real time, with conflict resolution rules for simultaneous sales and a reservation system that holds stock the moment a customer starts checkout rather than at payment confirmation.
Overselling incidents dropped to near zero within the first two months, and the operations team gained a live view of stock across all 140 locations for the first time.
