I was just rewarded a large commercial account. I usually bill all my residential customers on the 15th of the month and their payments are due on the first of the next month. They all pre-pay for the month. Do any of you do the same thing or is this not right? I have gotten burned a couple of times for really late payments and think it is safer to try and get paid before doing the work. I have never had any complaints about the system I have in place. Now this commercial client is not really wanting to pre-pay for the month. It is a $775 a month contract, so I would give in but he is asking for the reasons why I ask for pre-payment. Am I wrong or right?
