There is no free lunch. Many LCO's before you have done this 12 month average billing. They think it will get customers to take the bait and sign up. Like new car dealers do with car leasing. Then time and again LCO's come here with the story of how the customer cancels half way through the season. LCO is left doing more work then they got paid for. Hence the LCO is left holding the bag. Car dealer's are much slicker with leasing they dazzle the sucker, er, I mean the customer with low monthly pricing then they bang the leasee's wallet when the car gets turned back in. Problem is people will not try a reverse bait an switch with the car dealers because the dealer's have pockets deeper then the leasee's and will have their lawyer ream the leasee that would try to cancel. Home owners are not intimidated by small LCO's so they will agree to a 12 month lower average price up front to get work done cheap and plan to cancel half way through the season. I see nothing to gain doing average billing. I do the work I want to get paid this month not get caught up 12 months later. Average billing attracts the scammer's and or those that can not afford to pay for what they purchase.
