I've been working for a customer for about 3 months now and I just get more and more frustrated on the quality of the work I'm doing for them. They are paying around 40% higher than the current marked value for the work I'm doing for them. At the moment I feel they pay way to much compared to the work I'm delivering to them.
I really want to talk with them about it, but I'm not sure how to bring it up. I don't want to continue to do the same bad work and just charge a lower price. They have a lot of work need to be done due to big changes in the laws regulating their industry. I have no idea if we are on track or not. It needs to be done by the end of 2022. They are just assigning me tasks and I solve them.
How can I talk with them about the bad work I'm doing without "telling them about if they don't feel the same".
