Hello,

We got a client in the  automobile industry who is  making over  50 M/ in 2020. They run their business  through 6 Entities that we have to keep up with . We as CPA firm doing a lot of communications, preparation work to catch up with filling his tax returns. 

We agreed  about the hourly rate for special projects like Taxes, consultation, tax planning ,etc.  to be $300/Hour. We  do have tax attorneys and Cpa's  who work in those assignments . We also have  separate monthly Bookkeeping agreements to review all his accounting work on monthly  basis. He  think that with that monthly agreement it  should cover everything .  We trying to find fair billing system for his special projects. He gave  us a lot of work outside the scope of our monthly agreement. He always forget about those  orders and urge about  the bill for those  special projects. Any idea how to handle such issue in systematic fair way. Thank you,
