Point of Sale staff management
When you have staff who help you to sell in person, you need to give those staff permissions so that they can use Shopify POS to run your store.
All Shopify POS staff need to be given access to Shopify POS by selecting the Give Point of Sale access to this staff permission in the Settings > Plan and permissions area of your Shopify admin.
To log in to Shopify POS using a Shopify ID or login credentials, staff need Shopify POS login requirements. If staff don't have all the required permissions, then they can only use a PIN to log in after staff with the required permissions has logged in first.
You can give different staff different permission levels to your store's Point of Sale (POS) 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 has to the various activities that are required to run your store.
