Sticky Tickets is able to hold onto ticket payments until you issue an invoice for the relevant amount.
Please ensure you let us know before posting your event, so that we can change the settings in your account (this only applies to your first event). Then once your event is complete, just send an invoice to firstname.lastname@example.org for the total amount owing.
Please note: You still need to complete the standard bank verification process before the invoice can be paid.
If you have any questions about this or anything else, please don't hesitate to contact us and we'd be more than happy to help.
