Appointments: How do I comp a service?

[VSM]

I dont get it.. there is not comp button to comp a service... or i just dont know how to use it. When i go to check out i dont see any option to comp it even though i have the comps all set up. I figured its for items only maybe so i created an item and named it the same as my service so that way i know, but then when i go to add services/items... before check out, i remove the service and add in the item but then i cant save it the save button is greyed out. Im confused why this doesnt work any help?

It lets me save when i add the service back in why??? When i dont want that I just want the item and then I want to check out.

Hey @VSM! You're right, at this time it's not possible to comp a service but you can comp an item.

I'm not sure why the 'Save' button is greyed out for you! Can you try closing and reopening the app? Or, if you're looking for a way to comp a service have you tried creating a 100% discount, and then applying that discount at checkout? It might save you the extra steps of removing a serivce and then adding and comping an item!
