About SellUp • Upsell App

Increase your revenue with SellUp

Want to know how to upsell products on Shopify?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 popup. Create the perfect upsell journey for your customers.

With SellUp, you can create bold, precision based cross-sells / 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 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 the perfect 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.

Great app! We can see it is working and customers are using the sell ups. Any questions have been quickly answered and Dan has been great and tweaking any aesthetic changes I asked for.

Don't Bother Grandma

I used this app to help me create an add on price to customise a garment. I like how easy it was to use. I would prefer it if it wasn't a product I had to add on but just a price as the add on itn't a stand alone product.

Two Comma PR

Dan was quick to respond and sort out the postioning of the upsell for me, and it looks fantastic. The sell up app in general is a really nice way to upsell to your customers.
