Rank offers by profit margin, not just revenue

Most upsell apps optimize for revenue, because revenue is the number they can see. But a $60 upsell at a 20% margin earns you less than a $40 upsell at a 55% margin — and if the app does not know your costs, it will keep pushing the wrong one. Profit Optimizer fixes that by bringing your cost of goods into the ranking.

UpsellEngine syncs COGS from Shopify and re-ranks recommendations by the margin you actually keep, across every placement. High-margin companions rise to the top; thin-margin ones step back. You still control the catalog and can pin or exclude products, but the default now favours profit instead of vanity revenue — the difference that compounds over thousands of offers.

Profit Optimizer changes the ranking, not the relevance. An offer still has to make sense for the shopper — a high-margin product no one wants alongside their cart will not convert, and pushing it would only train customers to ignore your offers. What the optimizer does is break ties in your favour: when two companions are both relevant, it leads with the one that contributes more profit. Combined with Inventory Rescue, it can also weigh in stock you need to move, so the offer that is best for the shopper and best for your books tends to be the one shown first.
