Permission structure determines who can take a mobile payment, look up a customer’s transaction, issue a refund, or change the account that runs the service. Those actions carry different consequences. A temporary cashier may need to accept a sale without gaining access to everyone’s payment history or the business’s payout settings.
A useful setup gives each person enough access to finish their job and makes sensitive actions attributable. It also accounts for shared phones, lost devices, outside bookkeepers, and integrations that keep working after a staff member signs out. The aim is to keep checkout practical while preventing routine access from becoming unrestricted control over money and customer information.
