Need Custom Pricing Logic on Shopify Product Page

Skills Required

Description

I'm trying to implement custom pricing logic directly on one of my Shopify product pages, and it's proving a bit tricky with the native setup. The goal is to dynamically change the price based on selected product options, quantity tiers, or user tags — and I need this to happen in real-time before the product is added to the cart.

While I’ve found a few apps that get close, none offer the exact flexibility I need without overcomplicating the experience or bloating the page. I’d prefer a clean Liquid and JavaScript-based solution that integrates seamlessly with the current theme.

Here’s what I’m aiming for:
✅ Real-time price changes on selection
✅ Compatibility with the Shopify cart and checkout
✅ Lightweight — no heavy third-party apps
✅ Easy to update or expand later
✅ Mobile responsiveness and clean UI behavior

If you've worked on similar Shopify customizations before, especially with Liquid and JavaScript, this should be a straightforward task.
