Helpscout doesn't come with built-in Shopify actions. If you sign up for a demo, ask them about Shopify actions. We can tell you that without custom configuration ($$$), you can't make edits and returns on Helpscout.

On Gorgias, we integrate tightly with Shopify so we can pull and push information instantly from Day 1. Using Gorgias, you can respond to customers and actually resolve order requests simultaneously. Your days of tab-shuffling and copy-pasting are behind you. In Gorgias, you will find everything you need in the right place to help your customers.
