By default, the annual membership will be from the first day of the first month following the month in which the organization’s membership was approved through the next twelve months. For budget reasons, some organizations want to specify an annual membership period other than the default.

Payment options

Members may choose either of the following two options:

Annual
- First payment: If accepting the default annual membership period, pay the full annual membership fee amount. If choosing another annual membership period, pay the pro-rated amount.¹
- Subsequent payments: Pay the full annual amount no later than the 15^th of the first month of the annual membership period.
Monthly
- Recurring monthly payments will occur automatically on or after the 1^st of each month. The first payment will be the first month after membership is approved.

¹Pro-rated amount calculated as follows:

A = annual membership fee amount
N = number of full months between the date membership was approved and the beginning of the annual membership period
Pro-rated amount = A x N / 12
