Unless you are accessing a trial, or free, version of Black Opal™ then an invoice for the Fee will be issued either annually, or each month starting one month (the "billing period") from the date you first agreed to the terms of this agreement. All invoices will include the Fee for the following billing period. We will continue invoicing you according to the agreed schedule until this agreement is terminated in accordance with clause 8.

The Fee may be varied by Q-CTRL no more than once every 12 months. Q-CTRL will give you at least 30 days' notice of any changes - if you do not accept any increase in the Fee then you may terminate this agreement or elect to change to a different Plan within such notice period.

If you elect to upgrade to a Plan with additional features, your Fee will increase to Q-CTRL's then current list price for such Plan, unless we have agreed to give you access at a different price. You may elect to downgrade to a Plan with fewer features, however no refund will be given for any Fee previously paid or payable. The Fee for the subsequent billing period will decrease to Q-CTRL's then current list price for such Plan, unless we have agreed to give you access at a different price.

4.2 Invoicing and Payment

All invoices will be sent to your nominated email address and also available to be viewed and printed via our website.
