Seamless Integration of Modern Payment Solutions Tailored to the Client’s Needs

Industry: Automotive

Client:  Sports Car Manufacturer

Short to the story

Grape Up resolved an automotive manufacturer’s challenges with their in-vehicle digital product purchase solution by enhancing user experience, creating a universal payment system, and delivering a stable, scalable solution.


A well-known automotive manufacturer’s in-vehicle digital product purchase solution posed several issues, including high cost, slow performance, and limited scalability. Our analysis revealed that the client struggled to define precise business requirements and enhance the user experience. Additionally, the development team required improved business skills and efficient dependency management to enhance project planning.

While our specialists were involved in several teams working on the project, one of the goals was the creation of a new payment solution that involved integrating the most popular payment systems into the client’s digital sales ecosystem.


During the initial phase, our focus was on the customer-facing store, where we developed and integrated the front-end component with dedicated microservices. We then transitioned to domain-driven development (DDD), redistributing responsibilities among teams to adhere to DDD principles.

We worked closely with multiple teams and stakeholders to develop a customized payment system that meets the client’s requirements. Our collaborative approach involved collecting comprehensive functional requirements and ensuring seamless compatibility with different sections of the store, where the payment system would be integrated.
