Seems everyone has a different idea about how to handle billing ,how much in late fee's or how to collect. What is you limit for a Customer on any particular job. Do you have policy(credit check ,previous customers only , etc...) or play it by instincts alone. This year , I left over $25,000 of statements on doors(no contracts) at mostly one time services ( little to no previous history) and have had $368 lost and about 1,000 still in question (over 30 days). So long as I get the $1000 (still hoping to collect that)It is worth it to me to leave the bill to allow flexible scheduling. As a matter of fact The $368 lost was from 2 accounts and I knew when I left the bill it was High risk by just talking to the customers before hand. How much will you guys bill before you need something upfront ? Or do you get a contract on everyjob big or small.
