Yes, our user permissions configuration allows you to control whether a specific user has read-only or edit abilities. You'll want to head under the Admin tab on the left-hand navigation menu and click on Users. From there, you'll want to hover your mouse above an existing user and click on Edit. This will then bring you to a new page that lists the currently configured user permissions. You'll want to scroll down next to the Customers permission and from there you can control the Read-Only/Edit functionality. This will work across both Customer pages and the Configuration pages allowing users to either have Read-Only access to both or Edit abilities.
