Where Stock Sync Falls Short
Supplier Feed Automation, Not Sales Architecture
Stock Sync imports product data from suppliers. It does not build the shopping experience that determines how those products are presented, bundled, or priced for customers.
No Bundle or Offer Stack Functionality
Stock Sync manages product imports and inventory feeds. It does not create tiered bundles, mix-and-match experiences, or cart-level reward structures.
Updated Products at Single-Product AOV
Stock Sync keeps product data fresh from suppliers. But fresh single products still sell at single-product AOV. Bundle architecture combines those products into multi-item offers.
Feed Automation Is Backend Efficiency. Bundle Architecture Is Frontend Revenue.
Stock Sync saves time on product updates. Tiergain generates revenue through bundle offers. Operational efficiency vs revenue growth. Both matter. Revenue growth has more upside.
