I work for my father's software company, we're a small company and had to downsize further because of hard times. We only have an overseas office overseas now and I have to go to work at client's offices or at home when I'm back. To help us out my father's 'friend' who is an older jewish guy (I would say gentleman but he's far from that) from NYC said hey I want to have a team there overseas to cut down my costs here in US and we wanted to share expenses overseas and we we're for it. So my father agreed with him that they will share 1/3 of all expenses. Which is very cheap at our old office since it was rent controlled for 6+ years (rent was around $750, but now rent is much higher if you move) Assuming everything was handled between them (I'm running the day to day operations trying to modernize the program with e-commerce integration and improving our support & development procedures), I come to our office to only find out they weren't billed for 7 months. When I asked him about payment since they weren't billed. He immediately got defensive and asked for a detailed report of all expenses. Which of course he's titled to and I gave him a very detailed excel sheet by - Month - Splitting salary, rent, internet, electricity and cash expenses accordingly to the agreement He asked me to reformat the excel sheet around 4-5 times, wasting my managers time there and mine. Saying that he can't read and its not clear, after the 5th time its obvious he's just playing games and saying I have an attitude. We had to move because of unforeseen issues (government corruption), Again I had to negotiate extensively to split our new office expenses, which was substantially higher. This was a headache going back and forth and it was finally done. I was leaving the balance until I get everything settled down here. Again he said I had an attitude problem when I said, we would need to go our separate ways if we don't come to a fair agreement. (now it was divided by the # of staff) He also refused to pay any security deposit for this new office. Claiming he doesn't have the funds, when the office spaces he looked at we're nearly $1000 USD in cost which would of meant a higher security deposit and someone that flies first class over here. He's also asking us to help him hire programmers, help purchasing computers, things we don't have time to do, and things that he as a grown man should do himself. The emails are constant and fast when its something that he needs help with, but when it comes to payment its completely ignored. I mentioned the balance again and I was ignored even after we had purchased a laptop for the conference room (I did it because my father said lets just do it and show good faith) and mentioned we are splitting the cost of the laptop. (since its mainly for him anyways, I don't usually do face 2 face meetings over Skype or whatever. We have Trello, slack, and freshdesk that fulfills most of our needs) Still no reply, now I have to force my hand. I informed him we will have to raise $500-$1000 on your invoice (import/export for international wire, if invoice amount doesn't match, bank does not release the money). At least I have the decency to let him know, unlike himself who just sat there 7 months not paying any bills and then avoiding it when its brought up and getting defensive. Then he replies to my father only and says I have an attitude problem and if he wants his team out of the office. I definitely do and did before. I know this sounds ridiculously childish but man I just need some outside opinion. In my 10+ years working with my clients, managers, and owners this is the most ridiculous thing I've ever faced. Am I in the wrong? Its just driving me insane. He's an older businessman, he has a Manhattan office, etc ,etc so it does make me think that maybe I'm doing something wrong.
