WHERE TO GO IN YOUR ACCOUNTKnox > Billing & invoices
BEFORE YOU START

Get the right details ready

Sign in to Knox using the account that owns the invoice or service. Have the invoice number available if you need to contact support.

Security first. Never include account passwords, card details or authentication codes in a support ticket.

FOLLOW THESE STEPS

Make the change in Knox

Work through each step in order. Keep this guide open in another tab if that is easier.

  1. 1

    Open Account details and check the company name, address and country.

  2. 2

    Update the information before paying or requesting invoice corrections.

  3. 3

    Applicable tax is calculated using the account and product configuration.

  4. 4

    Download the final PDF after payment for your records.

WHAT HAPPENS NEXT

Check that it worked

The billing page should show the updated status immediately after Knox receives confirmation.

IF IT DOES NOT LOOK RIGHT

Try this before contacting support

Refresh the invoice once. If the status still looks wrong, do not submit the same payment repeatedly; open a support ticket and include the invoice number.
