Hi @Khan01
We recently launched cross-sell/upsell conversion app which helps merchants to increase AOV and it is easy to create upsell or cross-sell offer for your customer when someone clicks on “Add to Cart” button so recommended cross-sell or upsell products will be shown.
Our app: Bagify → https://apps.shopify.com/bagify
I hope our app will help you and also we are very happy to get your feedback related to our app so we can improve it 
Thanks
