You can give as many colleagues access to your account as you wish. You can also determine which areas they can and cannot see.
Giving your clients read-only access to their account statement on Brightbook instantly allows them to see what they owe you, as well as all historical transactions. If you have a PayPal account they will also be encouraged to pay you there and then.
Allowing your accountant or financial advisor access to your data within Brightbook is far safer and faster than emailing or posting it to them.
