If You choose to extend the terms of Your Subscription Plan to access more or additional services/products during Your Subscription Term (a “Subscription Upgrade”), any incremental Subscription Charges associated with such Subscription Upgrade will be prorated over the remaining period of Your then current Subscription Term, charged to You, and due and payable upon implementation of such Subscription Upgrade. In any future Subscription Term, the Subscription Charges will reflect any such Subscription Upgrades.

We will invoice You for such Taxes if We believe We have a legal obligation to do so and You agree to pay such Taxes if so invoiced.
  5. Any payment disputes must be submitted before the payment due date. If the Parties determine that certain billing inaccuracies are attributable to Abzu, Abzu will issue a credit memo specifying the incorrect amount in the affected invoice.

If the disputed invoice has already been paid, Abzu will credit the overpaid amount to the following billing period. Nothing in the Agreement obligates Abzu to extend credit to any Party.

If You pay by credit card, the Services provide an interface for You to change credit card information (e.g. upon card renewal). You will either receive a receipt upon each received payment by Abzu, or a receipt may be obtained from within the Services to track subscription status.

This amount will not be payable by You in the event You terminate Your Subscription or cancel Your Subscription as a result of a material breach of the Agreement by Us, provided that You have provided due advance notice of such breach including the particulars of and the circumstances constituting the breach and its materiality to Us and afforded Us not less than sixty (60) days to reasonably cure such breach.
  4. We reserve the right to modify, suspend or terminate the Services (or any part thereof), or Your and/or Your Users’ rights to access and use the Services, and remove, disable and discard any Personal Data if We believe that You or any User have violated the Agreement.
