UpsellPlus is a Built for Shopify app for growing average order value with upsells across the entire journey — product page, cart, cart drawer, checkout, and post-purchase. Its standout is checkout: it adds native offers inside Shopify Checkout and lets you customize the thank-you page, all without a developer.
Key features
- Checkout upsells and customization: add upsell blocks and edits inside Shopify Checkout (checkout-page customization is a Shopify Plus feature), with dynamic offers based on cart contents.
- Post-purchase and thank-you page: one-click post-purchase upsells and downsells (single and multi-product), plus a customizable thank-you page with reviews and offers.
- Storefront upsells: product-page, cart, and cart-drawer offers, product add-ons, and frequently-bought-together recommendations.
- AI and testing: AI-generated offers, A/B testing, and real-time analytics, all from a no-code WYSIWYG editor.
- Integrations: works with major subscription apps including Recharge, Skio, Seal, and Smartrr; supports multi-language and multi-currency.
Pricing and rating
UpsellPlus starts at $49/month (Launch, up to $500 in app-generated revenue), with a 14-day free trial. Higher tiers scale with the upsell revenue you generate: $119/month (up to $2,000, adding checkout customization, checkout upsells, thank-you-page edits, and A/B testing) and $199/month (up to $5,000, adding subscription upsells). Annual billing saves up to 20%.
It holds a perfect 5.0 rating from over 130 reviews. Merchants report clear AOV and conversion gains, value the no-code setup, and single out exceptionally fast support — often a human reply within minutes.
Pitfalls
The headline checkout-page upsells and customizations require Shopify Plus, so non-Plus stores rely on the product-page, cart, and post-purchase offers. There is no free plan — pricing starts at $49/month and scales with the upsell revenue generated — and the review base, while perfect, is smaller than the largest upsell apps.
Conclusion
UpsellPlus is one of the most capable checkout and post-purchase upsell tools on Shopify, especially for Shopify Plus stores that want native, on-brand offers at checkout. With AI offers, A/B testing, and support merchants rave about, it is an excellent choice for stores ready to invest in upsells across the journey.
