Approving App Charges in Shopify
You're going away but you're the only one with access to these billing settings in Shopify? With the new from Shopify update, it is possible to allow specific team members to make changes to App-Plans and e.g. Upgrade a subscription if urgently needed.
In your Shopify Admin dashboard under Settings, check in Permissions if this is available on your Shopify Plan. Shopify might restrict this feature to larger Shopify Plans in some cases.
This comes in handy when you're going away, with these responsibilities being handed to the next person in case you need to upgrade your plan or increase your limit.
