Omnichannel is a retail and logistics strategy that integrates all sales and delivery channels, physical and digital, into a seamless customer experience. Unlike multichannel approaches where channels operate independently, omnichannel ensures inventory, customer data, and fulfilment processes are synchronised across online, in-store, mobile, and third-party delivery channels. In logistics, omnichannel fulfilment supports flexible delivery options such as home delivery, click and collect, and PUDO point collection from a unified inventory pool. Smart locker networks are key enablers of omnichannel logistics, providing a physical touchpoint that bridges online purchasing with convenient physical collection. Columat's smart locker solutions integrate with retail and logistics platforms to support omnichannel delivery strategies. Related concepts include click and collect and PUDO points.
