How payment plans work
If you have a multi-payment plan, then this acts as a Subscription and will automatically attempt to charge your Credit / Debit card when it is due. It will re-attempt any failed payments up to 3 times and you will get an automated email to advise you of this.
This image shows how a 2 payment option for the Multi-Author Book program displays. Rather than showing a total of $1300USD, it shows the total you are paying today ($650USD) and the number of payments you will be making. Payments are normally made on a monthly basis. If you have a custom payment plan, the frequency will be added to the title of the plan.
