How can I change the E-mail address and my PO number for my invoices?

You can change both the e-mail address and the PO number on which you receive your invoices. Follow these steps

1. Log in to the website using your account.
2. Go to 'company details'.
3. Make the necessary changes and save them.

Is it possible to enter multiple PO numbers?
You can set one PO number per account. In case you would like to have some services on a separate invoice with a different PO number, simply create a new account for these numbers. All you need is a new e-mail address for the second account.
