Just wondering where you draw the line. Lets say you are 1, 2, or even 3 years into your business. I spent 4 years in lawn care (not counting the childhood push mower days) and have since switched to transportation, but this can apply to any type of contract work really. Lets say you have one major contract, in my case $40,015 a year. This is your largest contract, and you can hardly support yourself if you lose this contract unless you win a bid with another company. This company sends you a weekly check, and as per the contract, it should be $745. You do an extra job for this company and agree on $315, thus making your check $1,060 for that week. Now this was 6 weeks ago. The week the check should have been $1,060, they write you $755. Next week $615, then $605, then $718, another $605 and today we're looking at $616.86. Mind you it should be $745 a week not counting extra work. I confronted the supervisor of the company 2 weeks ago after several ignored phone calls and he claims I was dishonest with the amount of work I was doing (a complete lie) and he will not pay what is written in the contract. This contract has been in effect for over a year. My reply was... the contract entails everything, and was signed and agreed upon. Now how would you handle this and where do you draw the line? Suck it up until you win another bid? Drop it and take a big financial hit?
