Fix: add to cart button not working
Nothing on a store costs more per hour than an add-to-cart button that does not respond. It is usually a JavaScript error earlier on the page stopping the handler from ever binding, and the error is often thrown by an app rather than the theme.
What’s included
- Reproduce the failure and capture the console error behind it
- Trace whether the theme or an installed app is throwing it
- Fix the handler so the button works on every product
- Check the full path through to checkout
Not included
- An app vendor's own bug, where we hand you the evidence instead
- Checkout faults on Shopify's side

That normally points at a specific product configuration — a sold-out variant, a missing option, or an app that only injects on certain templates. Narrowing that down is part of the task.

This is the kind of fault we treat as urgent, because it is stopping revenue. Send the store URL and an affected product and we will confirm what we are seeing before anything is agreed.
