Participant registration is mandatory in MeetingHand. Your participants are required to select a registration type in order to submit an abstract.
This does not mean they have to pay their registration fees immediately. You can allow your participants to select their registration types and pay later.
We understand that most of the participants want to pay their registration fees after their abstracts have been accepted.
In order to allow your participants to pay later, you need to activate the Do you allow reservations? option from the Incoming Payments Setup.
Dashboard > Event Settings & Setup > Incoming Payments Setup > Do you allow reservations? - YES
With this option open, your participants can upload their abstracts and they can keep their registration and other services in reserve mode. They can also complete their payments whenever they want with a credit card or with an offline payment method.
