I have a question regarding a commercial bid I am putting together. A condo complex wants me to bid on spring/fall cleanups, mowing, pruning, edging and installing approx. 60 yards of mulch. I have other commercial properties but not this size. I will be billing over a 9 month cycle for this contract and 3 months for the snow removal. My question is, I was thinking about asking for a substantial down-payment to cover costs of materials and then billing balance into 8 equal monthly payments. I don't think I should have wait for 2 or 3 payments to arrive before I recoup the materials costs ( I would like this up front). Have any of you billed like this in the past and do you think it would be acceptable for me to propose this request. Thanks in advance.
