I would like to lock down the items that I have loaded into the square site.  Ie:  Item photos, descriptions, pricing,  How would I do this?  Secondly, I am having issues with more than one team member marking my orders as completed and I only want to allow one person that ability.  How would I do this?

Hello @ShamrockShoppe. 

You can control how your Team Members use your Square account by setting up their Team Permissions. Learn more about our Team Permissions and how to set this up step by step here. 

In your Square Online Dashboard under the tab called Team, you will see that you can turn off your items so your employees can't make changes or edits (see picture below). This set up can get a bit confusing, if you feel like you need additional assistance, I would suggest calling our Customer Support Team to walk you through the process in detail. 

Let me know if you have any other questions.
