Frequency

Choose how often the invoice is made: daily, weekly, monthly or yearly. The Interval field spaces it out, for example 2 means every two weeks or every two months.

For a monthly schedule you also choose whether the invoice is made On a set day of the month (the day of the start date, 1–28) or On the last day of the month. Days 29–31 are not offered because not every month has them. A yearly schedule cannot start on 29 February.
