Suppose you're 20 cuts into a yearly contract signed for 36 cuts when the client sells his home. Its paid out monthly for 12 months. You had allowed $50 per cut x 36 is $1800/12 months = $150 per month. Per cut price would have been $1000 after 20 cuts but with the contract you've only received $750. How do you word the contract to protect yourself and recover the other $250 in case something like this happens? Thanks in advance!
