Dashboards are great until they aren't. The moment someone on your team asks "what was blended CAC by SKU last Tuesday, broken out by channel" and the dashboard just doesn't have that view, you're stuck exporting CSVs and stitching things together in a spreadsheet. That's the exact gap ecommerce analytics with API access is meant to close: instead of waiting on a product team to build the exact chart you need, you pull the raw data yourself and build it once, correctly, for good.
