B2B apps face unique design challenges compared to consumer apps, as they must integrate with complex systems like ERP and CRM software while appealing to diverse user personas and buyers who may not be the end users. Despite these complexities, users judge B2B apps based on the simplicity and usability they experience with consumer apps, leading to the importance of intuitive design. To enhance user engagement and streamline B2B apps, product teams can leverage behavioral economics and marketing psychology techniques, such as carefully defining defaults to reduce choice overload, incorporating game mechanics to motivate users, utilizing social proof to encourage adoption, and designing user sequences that leave positive impressions. These strategies aim to mask complexity, guide user decisions, and create a more enjoyable user experience, ultimately boosting engagement and retention.
