About SellUp • Upsell App

Increase your revenue with SellUp

Join 1000's of merchants who have multiplied their revenue by offering targeted upsell offers. Create on-page upsells that sit below the product's add to cart. Create Powerful Action Upsells that show when the Product's Add to cart is clicked, in a high converting upsell popup. Create the best upsell journey for your customers.

With SellUp, you can create bold, precision based cross-sells and upsells for your Shopify store. From the product page through to the thank you page, you can offer the best upsell flow at multiple touch points throughout the customer journey. You can achieve Product Add On's or change the upsell section title to anything you want. You can offer Post Purchase Upsells, powerfully positioned on the order confirmation page.

With some brilliant in-built design settings, SellUp will inherit your stores theme settings so the whole upsell process looks seamless as opposed to being "bolted on". You can tweak individual upsell elements to make sure your upsells look the best.

As well as selecting products to cross-sell and upsell, we also give you control over the message. Instead of displaying the offer's product title, you can display a powerful call to action. For example, if you were selling a coffee machine, an upsell could be some coffee filters. You could make the title, "Want some extra filters?" giving the customer a clear call to action for the upsell and a reason to buy.

SellUp is a great upsell app to turn single product orders into multiple product orders. Great for all Shopify stores including self-fulfilled, Dropshipping Stores, Print on Demand stores and digital product stores/NFT.
