Allow a customer to pay any amount he wishes (Overpayment on Invoice)
Allow a customer to pay any amount they have on their balance, above the invoice total.
Wanted to leave a tip, could not.

You can already overpay an invoice. Just type in the amount when prompted to confirm amount.
You cannot underpay however...I see someone asked about this below.
Wanted to pay 50% of invoice total. Was not allowed that option when making payment
Would like the ability to tip for petsitting services

John on regularly provides additional services that don't show on the invoice, I would like to be able to pay him for his excellent customer service.
