BankLink uses the Practice's unique BankLink Online sub domain to retrieve files for your particular practice. If you're an accountant that needs to access a BankLink client file usingBankLink Online which is currently being accessed by another practice, the sub domain will need to be edited.
This process will also need to be done if you have changed your Practice sub domain (e.g. a requested name change), or if the client has come to your practice from a previous accountant who also used BankLink Online.
