This seems like a silly question, but I just don't know what to do. My makeup artist is self-employed and accepts payment by PayPal, Venmo, cash, or check. For PayPal and Venmo she isn't registered as a business and doesn't send an invoice, you just send money like you would to a friend. I will be paying and tipping both at the trial and on the wedding day.
If I pay with PayPal or check, is it appropriate to include her tip in the PayPal or check payment, since it is going directly to her as the business owner? Or is it better to do a separate cash tip?
