Build Custom Shopify Checkout Upsell Logic

Skills Required

Description

I’m looking to optimize my Shopify store's checkout experience by implementing a custom upsell feature. The idea is to offer customers personalized product suggestions or add-ons right before they complete their purchase — ideally without disrupting the checkout flow.

This isn't just about popups or standard product recommendations. I want something more integrated and native to the Shopify experience — ideally tailored based on cart contents, past behavior, or categories. It needs to feel helpful, not pushy.

You should be highly skilled in Shopify Liquid, JavaScript, and front-end customization. A deep understanding of UX best practices in eCommerce is a must.

Here’s what I’m hoping to include:

✅ Display upsell offers during the checkout process
✅ Dynamically suggest products based on what’s in the cart
✅ Clean and responsive design that matches my brand
✅ Easy to update or adjust offers as my inventory evolves
✅ Doesn’t interfere with third-party apps or payment flow

I’m open to ideas — whether that’s sliding panels, inline offers, or dynamic blocks in the cart summary. You can also advise on what works best based on your experience with similar customizations.

Performance is important. I don’t want anything that slows down the checkout experience or causes errors with payment processors or shipping calculations.

Let’s collaborate to make this an elegant enhancement, not an annoying upsell hack.
