With Simpletix you cannot directly setup invoice option or partial payment. But you can use the options within the system to make it work. This is how it would need to be done.

- You can open your event > Event times.
- Select the time you would like to edit:
- We recommend that you can create two ticket types for same ticket. (As shown in picture above)
One would be full price
Second would be Partial or by invoice (Which could either be $0 or anything above). Although it is advisable that you should take a small payment and consider that to be like seat booked.
Organizer needs to contact anyone who buys the second option separately for payment as it would not be from SimpleTix.
You can also setup an inventory for both ticket and an event capacity in case its required.
