When dealing with a client who's been burned before by vendors, you can earn their trust faster by learning at first what has happened. Then, you stress to them that not all fingers are equal, demonstrate in a positive manner how different you are. At the same time, give them some successful past solutions you offered to other clients in related situations. Establish with them a communication timetable, do not hide anything, seek their feedback, promise and keep your promise that you will not let them down whatever it takes. Provide and nurture a climate of trust and view things from their perspective too.

Listen: Hear their story and try to find your way to his heart. Be Reliable: Do what you say. Prove Yourself: Show your work.

To earn the trust of a client who's been burned by vendors before, I would focus on transparency, clear communication, and delivering consistent results. I would take the time to understand their concerns, set realistic expectations, and demonstrate my commitment to their success through follow-up, reliability, and a proactive approach to problem-solving. Building trust is a process, and I’d work diligently to show that their satisfaction and success are my top priorities.

1) acknowledge their sentiment, make sure they feel heard and just be kind and have a normal human interaction. 2) A free trial has always been a welcomed treat in which clear expectations have to be set and achieved to make sure the value is there. 3) whenever possible I arrange a meeting between an existing customer and the prospect to get a social proof and peer buy-in, using a champion from a won deal gives the solution more validity as it is given by "neutral" third party. 4) When possible, an outcome based pricing makes it more interesting for prospects to commit longterm, by setting a clear and achievable target, gives the new customer a great way to only pay full price if, as a company/solution, the promised results get delivered
