What it does

Stackline is an enterprise retail-intelligence platform that connects ecommerce sales data with advertising performance across Amazon, Walmart, Target, Instacart, and other retailers. Its Beacon analytics product ingests point-of-sale, traffic, conversion, and share-of-category data so brands can see exactly how products are selling, where they are losing shelf or search position, and how competitors are moving. On top of that measurement layer, Stackline offers activation tools to plan and optimize retail-media campaigns and budgets, tying ad spend back to incremental revenue rather than isolated ad metrics. Large consumer brands use it as a single source of truth for omnichannel ecommerce, replacing fragmented retailer dashboards and spreadsheets with unified reporting across their entire retail footprint.

Where it fits

Stackline operates at the analytics and optimization stages, linking retail-media activation to actual sell-through across the retailer portfolio.

Core features

  • Unified sales, traffic, and market-share data across major retailers
  • Beacon analytics combining point-of-sale with advertising metrics
  • Competitor and category benchmarking

Best for

Beginner notes

  1. Start by connecting your priority retailers so share and sales trends are comparable in one view.
  2. Use category and competitor benchmarks to set realistic share-growth targets before scaling ad budgets.
  3. Tie every retail-media campaign back to incremental sales in Beacon rather than judging it on ACoS alone.
