Verdict on Upsell.com

ReConvert is the undisputed leader in post-purchase upsells on Shopify. Its one-click upsell funnels and thank-you page optimization are unmatched, and the revenue it generates typically pays for itself many times over. The revenue-based fee above order caps is worth noting, but for most stores the ROI far exceeds the cost. If post-purchase optimization is your priority, ReConvert is the clear choice.

Verdict on NML

NML Quick Add to Cart is a completely free app for adding quick-purchase buttons and upsell recommendations to catalog pages. With zero reviews, it is unvalidated. But since it is free, there is no risk in testing. The GA and Facebook Pixel integration is a useful bonus.
