UpsellPlus covers upsells and cross-sells across product pages, cart drawer, checkout, post-purchase, thank-you and order status pages, in a similarly broad scope to Zipify OCU and Aftersell covered earlier in this project. It carries the **Built for Shopify** badge and shows a perfect 5.0/5 rating on 123 reviews. It's developed by UpsellPlus. ### How does the app work on a Shopify store? Merchants add product page and cart drawer upsells, cross-sells and free gifts, create one-click post-purchase upsells and downsells without redirects, and customize checkout and thank-you pages with upsells and dynamic content. Offers can be personalized with rules, AI recommendations and subscription upgrades, with multivariate A/B testing and live analytics tracking AOV, conversion and offer revenue. It's currently English-only and connects to Shopify Checkout, customer accounts, Shopify POS, Appstle, Klaviyo, Recharge, Skio and Smartrr, several of which have been covered earlier in this project. ### Why choose UpsellPlus over another full-funnel upsell app? Covering nearly every stage of the funnel, from product page through thank-you page, puts it in the same category as Zipify OCU and Aftersell already covered in this project, worth comparing all three directly since they overlap heavily in scope; UpsellPlus's differentiator is multivariate A/B testing (testing multiple variables at once) rather than simple A/B splits, a more statistically rigorous approach. Native integration with subscription apps (Appstle, Recharge, Skio, Smartrr) already covered in this project is a genuine plus for stores running recurring revenue upsells alongside one-time purchases. The free tier is limited to a single offer, a fairly tight ceiling that will push most active stores toward at least the $49/month Launch tier quickly, with checkout customization and thank-you page personalization reserved for the $119/month Shopify Plus tier and above. ### What are the 3 main features of the app? 1. **Full-funnel upsells**: product page, cart, checkout, post-purchase, thank-you page. 2. **Multivariate A/B testing**, alongside AI-powered offer recommendations. 3. **Native subscription app integration**: Appstle, Recharge, Skio, Smartrr.
