When you add a pledge to your database, you should establish a schedule for the payments via Frequency:

  1. Single (one payment)
  2. Weekly (once a week)
  3. Biweekly (every two weeks)
  4. Semi-monthly (twice a month)
  5. Monthly (once a month)
  6. Bimonthly (every two months)
  7. Quarterly (four times a year)
  8. Semi-annual (twice a year)
  9. Annual (once a year)

Installments can also be paid on an irregular schedule, which means the payments do not fit into one of the regular schedules. For example, a constituent may request to make a payment every three weeks.
