The term Unified Commerce is a new and exciting concept that changes how we look at the systems that support our sales operations. It builds on the concept of Omni-Channel, but it expands its scope and it changes the fundamental rules. Omni-Channel is about creating a consistent customer interaction regardless of the channel; store, call center, web, or mobile.
The traditional approach to Omni-Channel is to ensure that each of these channels is tightly integrated. It is common that each channel is serviced by a different system / technology with separate controls. Unified Commerce takes the traditional use of multiple channels and consolidates them into one, commerce, effectively blurring the differentiation of channels.
Unified Commerce also expands its scope from consistent customer interaction across channels to consistent end to end execution of servicing the customer. This begins with product selection / merchandising, ends with order fulfillment, and includes everything that happens in between.
