Since 2012, iFit's business model has been highly flexible and diversified, involving both online and offline channels, with a level of complexity far higher than imagined. Therefore, building a system tailored for iFit from scratch significantly improved the efficiency and accuracy of iFit's back-end operations. In 2016, in response to the needs of our e-commerce peers, we migrated and integrated iFit's proprietary system and warehouse management processes to launch the ECFIT third-party warehousing service. Subsequently, through accumulating more experience, all aspects of the system's functions were significantly enhanced. Through observation and contact, we found that although some enterprises currently have no need for third-party warehousing, they still require systems for shipping, receiving, warehousing, and tallying management, yet they struggle with the dilemma of excessively high costs in selecting, implementing, and maintaining appropriate software. In 2018, the original ECFIT third-party warehousing service system was transformed into a cloud SaaS product, and the [ECFIT Intertidal] back-end integration system was launched. This allows more small and medium-sized enterprises to access such services with a low entry barrier of "a monthly fee of just a few thousand yuan," providing a one-stop solution for enterprises with self-managed warehouses.
