The project has taken a while and now it's 80% done. My client called me today and he wants me finish the work at his office so that he will be able to work beside me. I accepted his offer, then upon reflection I regretted accepting because I cannot finish it at his place since there are some parts of the project that other people (freelancers) are working on.
What are my options to avoid this situation? I will meet him in person next week! Should I email him and tell him a cannot do the work on-site? If so, how should I word my email?
