Cobot gives the option to add a one-time signup charge as part of enrolling for a new plan. This is charged to the member the first time they enroll for any plan in your space.
From now on any new members choosing that plan will automatically have the charge added to their first invoice.
Please note this does not affect existing members or members changing their plans. To issue them a charge, use the One-Time charges feature
If your space offers deals for companies or negotiated with individual members, you can assign them a plan and then customize it.
