Point of Sale staff management
When you have staff members who help you to sell in person, you need to give those staff members POS permission so that they can use Shopify POS to run your store. You can give different staff members different permission levels to your store's Point of Sale and retail activities using POS roles, which are a set of permissions. You can create different POS roles that, when assigned to your Point of Sale staff, determine how much permission each staff member has to the various activities that are required to run your store.
If you're the store owner, or you have the Manage Point of Sale staff permission, then you can use Shopify POS or the Point of Sale channel in the Shopify admin to manage your Point of Sale staff and assign them roles. Each Point of Sale staff member must have a role assigned to them.
