The development of an complex ERP system required building approximate 20 modules. We chose to create a CRM module from scratch rather than using a third party to confirm deeper integration, greater speed, and customization options. The solution delivered was incorporated with SAP, providing extra strength of streamlining and automating processes. Over the whole period of the system maintenance that continues up to the present day, our team has utilized several technologies, regularly changing them to more advanced or better-suited ones, ensuring the solution is always up-to-date. All updates to the systems are made only in case of necessity.
