Challenges & Solutions
A client faces several challenges when entering the e-commerce space, for which our Buyer App provides effective solutions:
- Platform Dependency on Sellers: Traditional e-commerce platforms require sellers to register and list products, limiting scalability and reducing product availability. Solution: The STS Buyer App, built on the ONDC network, eliminates this dependency by aggregating products from multiple sellers already listed on the network.
- High Operational Costs: Traditional e-commerce platforms incur significant operational and maintenance costs, including logistics, seller management, and inventory optimization. These expenses hinder scalability and reduce profitability. Solution: By leveraging ONDC, operational responsibilities are shifted to Seller Apps, significantly reducing costs and enhancing efficiency for Buyer Apps.
- Domain-Specific Barriers: Traditional e-commerce platforms operate with distinct services for separate domains increasing complexity and fragmented ecosystems. For instance, Food & Beverage requires a completely different infrastructure compared to Electronics. Solution: The ONDC network, coupled with our expertise as a Technology Service Provider (TSP), unifies multiple domains into a single, cohesive service. This removes domain-specific silos and provides buyers with a seamless experience.
