We have had a client for a while and everything has been very smooth with him. Recently, we have been unable to contact him (for the past 3-4 weeks), and we were informed that his partners were not able to contact him either. He still owed us money ($675) so we started sending invoices. Yesterday, he sent an e-mail with 15 accusations (14 incorrect, 1 correct) demanding his payment thus far ($1325) to be returned else he would sue us. The accusations are things we can prove inaccurate or are for things we never agreed to do or even explicitly said we would not do. I already informed the client that his 1 correct accusation was indeed correct, but that we could prove his other 14 completely false. However, my partner and I are just teenagers, while this guy has loads of money. I'm in school and run this business, so I don't have any spare time for legal issues. Would you suggest just paying him the money or actually attempting to get this overturned? We were thinking of just giving the money, but provide a written agreement that the client will not pursue this in the future and that the matter is closed. What do you think? Edit: Also, I have sent the client and his team an accusation-by-accusation rebuttal to his claims, have sent numerous text messages attempting to contact him, and have my partner calling him on the hour every hour to no avail. We assume he will avoid us during his 7 day deadline, after which he will take us to court.
