Digismoothie's Shopify upsell app with eight offer placements, volume bundles and a slide cart.
Best for: Shopify stores that want one app to cover upsells from product page through post-purchase, including a replacement cart drawer.
Suggest add-ons, bundles, and upgrades on product pages or at checkout to raise order value.
Upselling software encourages online shoppers to increase quantities, add related products, or accept an upgraded offer. Placement matters: an incentive on a product page shapes the initial purchase, while a cart recommendation and a post-purchase offer reach customers at different stages. Some applications specialize in quantity discounts, and others adapt recommendations to visitor behavior. Shopify eligibility restrictions also vary by placement. These five products are organized around the point in the shopping journey where each makes its strongest contribution.

Upsells Along the Purchase Path
#1 of 5 in Upselling
Candy Rack supplies several Shopify offer placements, including product pages, its own slide cart, and post-purchase pages. Volume bundles encourage higher quantities while the rewards bar provides an additional cart incentive. Its ability to place different offers at separate shopping stages distinguishes it from applications centered only on the moment after payment.
Personalized Cart Suggestions
#2 of 5 in Upselling
Rebuy's Smart Cart adds product recommendations and rewards-bar incentives directly to a Shopify cart drawer. Merchants can configure cross-sell placements and progress indicators that change as shoppers add items. Rebuy also offers recommendation widgets for later order pages. This provides continuity across different shopping stages instead of relying on a single static product bundle.
Quantity Break Promotions
#3 of 5 in Upselling
Kaching Bundles creates offers in which buying additional units changes the incentive. Quantity Breaks, Buy X Get Y, and bundle upsells support different promotion structures. The vendor also documents linking quantity choices with distinct subscription plans through Kaching Subscriptions. This is particularly relevant for consumable products where a larger initial quantity or recurring order is the intended upgrade.
Offers After an Order
#4 of 5 in Upselling
AfterSell specializes in offers shown immediately after a shopper submits an order. One-click post-purchase flows let eligible customers accept additional products without repeating the ordinary checkout. Smart Funnels adjusts offer selection based on purchase context. Its workflow targets a specific window after the initial order, rather than primarily influencing the product selection made before checkout.
Behavioral Product Recommendations
#5 of 5 in Upselling
Nosto changes recommended products based on shopping behavior, product attributes, and merchandising controls. Teams can configure recommendations according to inventory, audience segments, and business rules rather than showing the same offer to every visitor. This approach differs from a fixed quantity discount because the suggested product can adapt to visitor context and the store's available catalog.

Upselling encourages the customer to choose a larger quantity or upgraded version of an intended purchase. Cross-selling recommends complementary items. Candy Rack provides product add-on and volume offer placements, while Kaching Bundles manages quantity promotions and related bundles. Rebuy and Nosto add contextual product recommendations. Depending on configuration, one application may support both sales techniques.
Supported post-purchase applications can display an additional offer after the original order is submitted. AfterSell emphasizes one-click post-purchase offers, while Candy Rack offers post-purchase placements. Rebuy also provides recommendations on later order pages. The experiences have different rules and eligibility requirements, so a thank-you page recommendation should not be confused with changing the original order.
No. Product-page and cart offers can run without requiring Shopify Plus in many configurations. However, Candy Rack documents that embedded checkout offers require Shopify Plus. Other applications have restrictions on their checkout extensions or post-purchase conditions. Confirm the exact surface and supported payment flow rather than assuming every advertised placement works in every Shopify storefront.
