Many eCommerce projects fail due to problems integrating front-office applications with back-office order tracking and execution. This "integration gap" is a particular challenge in B2B scenarios because they involve complex, heterogeneous application landscapes in both front- and back-office domains. This report explains how B2B order management (B2B OM) platforms can bridge that gap, even in global federated organizations for which a single omnichannel platform is impractical. We describe the different types of B2B order management that are available and explain how central application development and delivery (AD&D) leaders can incorporate them within their enterprise commerce application strategy.
