ok, u do some seeding, spend xx amount of money on seed, starter fert, and u dont have the results that u wanted, maybe an early frost, customer doesnt water, etc. now, my rule is always get paid for seeding, and leaf cleanups on the spot because these r two areas where "anything can happen". but, once in a while for a steady customer u just add it to their monthly invioce. so, what happens when they say say, "u charged me $120 for powerseeding, and starter fert, and it really didnt come in that good, i dont want to pay this bill." this is y i always (almost always) get paid for seeding on the spot. so, what do u do? take it off the bill? demand payment? this is one of the highest risk services to provide, afterall, if they didnt water their lawn to begin with, and thats y its in need of seeding, what makes u think they will water the newly seeded lawn? and when u tell them its cus they didnt water, they look at u like u r trying to b.s them.
