Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureQuantAftersell helps merchants boosting their order value by creating post-purchase upsell funnels that appear immediately after checkout. Merchants can show relevant product deals to customers who have already completed payment, without interrupting the checkout process. The app allows flexible funnel setup, targeting, and performance tracking to optimize post-purchase revenue with minimal effort.
Get an ultimate sales boost by reconverting buyers after payment: a post purchase offer before the thank you page, upsell bundles on the checkout page, upsell & cross sell with related products and recommended products. A post checkout upsell and order status page upsell keep selling, and a multi-product downsell follows a declined offer.
