Tipping on Gumroad
A couple of summers ago, I was asked to design and implement a solution to adding tipping to the checkout flow in Gumroad. It was an experiment. Customers in the US are used to tipping but would it be a behaviour that would translate to an online purchase? Would non-US customers understand the concept? And importantly, how much should the UI and flow differ from the experience you are used to in a cafe?
Development work.
