Checkout Champ

Checkout Champ is a funnel and checkout platform used by direct-response brands running upsell and continuity offers.

Funnel checkouts often sit outside the main storefront, which is exactly where tracking tends to break — and why capturing those orders on the server matters.

Checkout Champ runs the funnel: a landing page, an initial order form, and a sequence of one-click upsell steps after the first purchase. Each accepted upsell is recorded against the same session but creates additional order value after the initial conversion has already fired. Continuity offers create recurring billing on top. Because the funnel is a separate surface from any main storefront, its order numbering, customer records and event stream are its own.

Funnel revenue arrives in pieces — an initial order, then upsells accepted seconds later. Upstack captures the whole sequence server-side and forwards the complete order value rather than the first step, so the platforms optimise against what the customer was actually worth. Funnel buyers are resolved against the same graph as storefront buyers, so a customer who came through a funnel and later bought from the main store is one person, not two.
