Is there a way to show Venmo as a payment option? I see where I can add Custom Payment Method, but there is no way to edit the title so the guest sees Venmo as a choice.
Also is there any way to collect and store photo ID's yet?
You would have to use the Custom Payment Method and then specify that in the instructions body. You're right about the title that it shows - we've had requests to change that title so something like "Venmo" could be put in there. At the moment, we don't support that however.
No built in way to collect and store photo IDs or other file uploads yet, but it's on the dev roadmap.
