We built an app that tackles common pain points for sellers, dealers, and the entire automotive industry, resulting in increased efficiency and broader reach.

Snelweg Deals (SWD)

Business Context

The traditional car selling process can be clunky and time-consuming for sellers and dealerships. Sellers need help finding buyers and getting the best price, while dealers spend hours sourcing vehicles. SWD saw an opportunity to improve this by creating a centralized marketplace app that simplifies listing, streamlines bidding, and connects buyers and sellers efficiently.

Still curious?

  • What are the biggest challenges in developing a car marketplace app?

    One major hurdle is ensuring a secure and seamless user experience. This integrates secure communication channels, robust user authentication, and reliable data storage. In SWD, we achieved this by leveraging a combination of technologies, such as AWS Serverless Lambda for secure backend functions and GraphQL and Hasura for efficient API management.

  • How can I create a user-friendly listing process for both sellers and dealers?

    Simplicity is key! An intuitive interface with clear instructions and drag-and-drop functionality for adding photos and vehicle details can significantly improve listing times. In SWD, we used a combination of React JS and Flutter to create a user-friendly experience across mobile and web platforms, leading to a reported 3x faster listing time for sellers.

  • What are the benefits of integrating a bidding system with manual negotiation?

    Transparency and flexibility are crucial for a thriving marketplace. A bidding system with the option for manual negotiation allows sellers to receive higher offers while allowing buyers to discuss specific details. SWD's implementation of this feature resulted in double the buyer engagement compared to traditional methods.

  • How can I ensure my app caters to both individual sellers and dealerships?

    Developing separate user roles with tailored functionalities is essential. Sellers might need a simple listing interface and secure communication channels, while dealerships could benefit from features like bulk listing and inventory management tools. We addressed these diverse needs in SWD's project through a well-defined user role system.

  • How long does it typically take to develop a marketplace app like SWD?

    The development timeline depends on the app's complexity and feature set. However, with a clear vision and an experienced development team, you can develop a well-designed marketplace app like SWD within a reasonable timeframe. Contact us to discuss your project and explore the possibilities!
