The idea

Sellers who list on many marketplaces were logging in to each one separately to publish products, pull orders and buy shipping labels. Stock went out of sync, shipping was slow and expensive, and there was no single financial picture. The platform, now live for omnichannel sellers, wholesalers and 3PL warehouses, brings all of that into one system.

The challenge
  • Connect marketplaces with very different APIs: XML for some, JSON for others, Graph API for social commerce.
  • Publish products and pull orders in bulk without slowing the system down.
  • Choose the cheapest suitable carrier and service for every order automatically.
  • Keep large product, order and stock tables fast to search as volume grows.
What WeyBee did

WeyBee built the core platform on ASP.NET MVC and MS SQL, with RabbitMQ and asynchronous processing for bulk work. Each sales channel has its own integration, whatever API style it uses. A rate-shopping algorithm and SKU-level shipping preferences pick the carrier and service from the product's specifications. Indexes, query tuning and XML-based stored procedures keep bulk operations fast.
