Setup your payment periods

When you click on the 'Edit Period' button in the 'Registration types/fees' tab, you can choose the number of Payment Periods.
‘Payment Periods’ is a drop-down menu where you can set the number of payment periods with a minimum of 0 and a maximum of 3.
When choosing 0 periods, it means the congress doesn't have any paid events and no amounts can be added to the p-events.

In our example we've chosen for 2 payment periods: Period 1 and Period 2.
As shown above, you can specify the start and finishing date per Period. 
The last period is always between the specified start date and the start date of the congress.
