I want to try out a new app for client interactions and help desk ticketing, but I’m not ready to cut over from Inbox to this yet…I want to test this out somewhere first. Is there no way to have a dev/staging store where I can deploy an app and interact with it to make sure I understand the implications and get it setup the way I want it, before I make it go live?
Work with a partner to setup a development-store that’s a free/monthly, or also for the dev-dashboard if access available.
limitations: https://shopify.dev/docs/api/development-stores
If your or a partner have access use the developer-dashboard in EARLY ACCESS(aka beta)

If you need a development-store process setup then contact me for services.
