What is the name of your state (only U.S. law)? California
I did some accounting work for another accountant who has failed to pay me going on 3 months now. He has been invoiced several times. Is there a customary late fee percentage to charge? I am drafting a final letter to him demanding payment and would like to use a reasonable percentage. Unfortunately there exists only a verbal agreement for the work and no previous discussions of "what if" for any late payments. Thanks for any info.
