About SellUp • Free Upsell App

Increase your sales and up your upsell game with SellUp

Join 1000's of merchants who 10X their revenue by offering targeted upsell opportunities. 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.

With SellUp, you can create bold, precision based cross-sells and upsells for your Shopify store. SellUp is powerful in that you can introduce SellUp just below the products main Add to Cart button. You can achieve "Frequently Bought Together" bundles or change the upsell section title to anything you want. You can also offer Post Purchase Upsells. These are powerful Upsells that appear in the order confirmation page. They are powerful because you can offer an upsell straight after a successful checkout to a logged in customer.

With some brilliant in-built design settings, SellUp will inherit your stores theme settings so the whole upsell process looks seamless. You can tweak individual upsell elements here and there also.

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 call to action. For example, if you were selling a coffee machine, the upsell would be some coffee filters. You could make the title, "Want some extra filters?" giving the customer a clear call to action for the upsell.

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.

Wish the regular plan had more than one upsell, but the one-page works great. Love that the font default to be cohesive with my store theme unlike other upsells apps!


Advertised as free but in order to use it, you have to upgrade. It only allows you to do ONE upsell for free. Past that that you cant create an additional unless you pay the associated fee to upgrade. Other than that it is sleek and easy to use.

Whilst we appreciate your feedback, we feel this is an unjustified review of SellUp. SellUp clearly states it is free for 1 Upsell so installing the app to then leave a negative review could be against ToS. Please reconsider this review.

this app is listed as a free upsell app but you can list only one product, if that's the case it is not a free upsell app! 0 return at this point

Thanks for your review.

It seems like you want the premium version for free! Well, if you have a Shopify store and are a serious merchant, then you could setup an ACE upsell strategy and the app would pay for itself :) It would also make you a nice ROI. Quite a few of our merchants are making over 1500% ROI from this app.

As a Shopify Partner and App Developer, reviews like this are disheartning as you are criticising a price you aren't willing to pay. If that's the case, leave no review at all. We provide 1 upsell free of charge. Thats a cost out of our pocket at ZERO cost to you! FREE!

Any free products going at De Noir? Checked out the store but looks to be a drop ship store.

I hope you consider altering/removing this review but if not, hopefully savvy merchants will see through this.

All the best,

LAUNCHTIP, Shopify Partner.
