Day-to-day work. The default for most team members.

What Staff can do

See lists in the shops they're added to
Scan barcodes, add items, mark items purchased
Take and attach photos
Submit items for approval (when their role is in the list's approver roles)

What Staff can't do

Invite, edit or remove other staff
Freeze lists, manage templates, print labels
Mark items as non-carrying (slow movers / stop carrying)
Change business or shop settings

Staff + Buyer is a common combination

Most people doing wholesaler runs are Staff with the Buyer capability turned on. They can't manage the team or change settings, but they get the Buy tab to pick items at the wholesaler.

Approval queue

If a list has Staff in its approver roles, Staff members on that list can submit and approve items in that queue. By default lists are configured so only Manager/Admin/Owner approve - talk to the person who set up the list if Staff approval should be enabled.

Department scope

Staff can be scoped to specific departments within a shop. They'll only see items in their departments - useful for big shops where floor staff handle one section each.
