this year i plan to sub out the fert programs. my problem is this: i will arange the service for the cust, fert man will bill me after each aplication. only thing is this, i bill customers at the end of each month, fert man bills me whenever he does it, and wants payment within 2 weeks, this means sometimes i have to shell out alot of money, and get reembersed by my customers. what id like to do, is ask the customers to pay upfront in full at the beggining of the season, and offer them a discount for doing so. some of my regulars i know will not have a problem with it, but i am targeting new customers too, and wonder if they will have a problem paying up front. any input is greatly appreciated, thanks guys.
