A small example but I did a web application for a client that is the main support of their business in the Backoffice and this was in 2019, i still didn't ask them all the money for my work and i pay the monthly costs of hosting and i reply as soon as I can when they need help with anything. I don't want the money until i do all the changes that they wanted and I feel the app is with great quality. I want to provide quality and most of all honesty and assurance or trust that I will always be available to reply and help, and won't just go dark.
