The Scalable Stack Playbook: Eliminate Overselling Across All Your Channels

Are you selling across multiple channels like your own BigCommerce store and Amazon? You're likely facing the costly problem of overselling. When a product sells on one platform, the delay in updating stock levels on others leads to cancelled orders, frustrated customers, and negative reviews. This damages your brand's reputation, wastes valuable customer support time, and can even lead to penalties from marketplaces.


This playbook details 'The Scalable Best-of-Breed Stack,' a powerful solution designed to conquer multi-channel inventory chaos. By using Linnworks as a central automation hub, this stack creates a single source of truth for your inventory. It seamlessly connects your BigCommerce store and Amazon Seller Central, ensuring that when a sale happens anywhere, stock levels are updated everywhere in real-time. This unified data also flows into Zendesk, empowering your support team with the accurate order information they need to provide exceptional service.

Expected Outcomes

  • Complete elimination of overselling and accidental stockouts.
  • Real-time, accurate inventory visibility across all sales channels.
  • Significant reduction in cancelled orders and customer complaints.
  • Improved brand reputation and marketplace health scores.
  • Increased efficiency for customer support teams, leading to faster resolutions.

Integration Logic

  • PolySync Hub

    PolySync Hub orchestrates a bi-directional flow of data between your core systems. 1) Orders from BigCommerce and Amazon Seller Central are automatically created in Linnworks for centralized processing. 2) As stock levels are updated in Linnworks (due to sales or new inventory), these levels are pushed back to BigCommerce and Amazon listings to ensure accuracy and prevent overselling. 3) When an order is processed and shipped in Linnworks, the fulfillment status and tracking information are updated on the original sales channel (BigCommerce or Amazon). 4) When a customer creates a ticket in Zendesk, PolySync Hub enriches the ticket by pulling the customer's recent order history from Linnworks and BigCommerce/Amazon, giving support agents immediate context without switching systems.
