Winning in an omnichannel world demands excelling in all channels, from in-person to hybrid, inside sales, digital self-serve, and marketplaces. According to McKinsey the average shopper now interacts with retailers through multiple touchpoints before making a purchase decision. This number has doubled from five touchpoints just a few years ago, indicating the growing complexity of the customer journey. The success of an omnichannel strategy hinges on efficient service offerings and meticulous stock management to ensure product availability across all channels. However, what appears seamless on the front end necessitates a coherent and connected approach on the back-end. A critical component of a well-executed omnichannel strategy involves the integration of payment systems, to ensure that shoppers can easily complete transactions regardless of the channel they choose.
