By verified merchant review volume, Upsell.com ‑ ReConvert Upsell from Upsell.com ex ReConvert leads this category with 2,777 reviews and a 4.8-star average. Review count is the closest public proxy for install base — the Shopify App Store does not publish install numbers.

Essential Upsell & Cross Sell holds the highest rating in this category at 5.0 stars across 2,195 reviews. We only rank apps with at least 10 reviews — a five-star average from two reviews is not a rating.

By verified merchant review volume from the Shopify App Store, highest first. We do not accept payment for placement and there are no sponsored positions in this list.

The catalogue is refreshed weekly from the Shopify App Store. Ratings and review counts move between refreshes, so always check the app listing itself before installing.
