[WPMU DEV Dashboard] Tip Option in Client Billing (Invoice)

2

Would LOVE an option like Fiverr where a Client can have the option to pay their Bill as invoiced but allows them to include a Tip if they should desire. I have had a few clients that do this and can’t with Client Billing and then try to Paypal or Zelle me the money separately…would be nice to have them do it through Client Billing. ;)

Thanks!
