Let's say I accept a contract on Upwork but, for whatever reason, I'm unable to deliver what was promised. I would, of course, be willing to offer the client a full refund. My question is: Can the client still leave a public negative review on my profile if either the client or I cancel the contract? This is one of the things making me hesitate before taking on my first job. I want to protect my profile and avoid a bad start, especially when I don't have any reviews yet. At the same time, I know I need to take a chance, gain experience, and start building my reputation. For those of you with experience on Upwork, how do you approach this risk with your first client or any client in general? Any advice would be appreciated!
