If you wish to change the default bank details for a Sales Invoice simply select the bank details in the bottom left hand corner of the invoice.

This will redirect you over to Settings > Invoicing. Under payment information you can toggle between the default bank account which will show on your invoices.

When you navigate back to your Sales Invoices the payment details will be updated to the newly selected bank.

You can then download a PDF copy of your invoice and send it to your customer or send this via email from within Ember.

For the next invoice you issue these bank details would then default to the newly selected bank. If you need to change to another bank then you can follow the same steps to change this back.
