I took on a graphic design job recently and I quoted the client for 36 hours of work. About half way through the project the client got stalled out because of upper management's indecision and because of that, many little changes started being made to the project. I am now up to almost 80 hours on the project and foresee another 10 before it's finished.
This is my first job with the client and I would like to continue receiving projects from them and hopefully procure a long-term relationship with them.
Should I consider this an investment and just charge them for the quoted work? Or should I re-quote them and if so, how should I go about doing that? Should I re-quote them the full amount?
What is the general practice for a situation like this?
