Use this form to change the way you use your credits. Two settings are available:

• Auto-deduct: this setting means that each time we send an you invoice, we'll use as many of your credits as possible, in order to reduce the total amount payable.
• Accumulate: this setting means that we'll never use any of your credits to reduce the total amount payable, unless you specifically ask us to.

The default setting for each customer is auto-deduct. With this setting, you don't need to remember to ask us to give you a discount.
