Do you need to change your bank details? 1. Click on the ‘Finance’ tab in the extranet and go to 'Bank details'. 2. If you wish to change any of this information, select 'Edit bank details'. Note: If you’ve changed the bank details or the contact person, you need to wait 24 hours (from the last change) to be able to make a new update. The change takes 7 days for validation and enabling it into the system.
