I have clients who are not paying already after their first month's cut!!! I would be patient but fuel is EXPENSIVE!! How do I get them to pay their bill? I sent the bill out at the beginning of the month with a due date of the 15th. I even put in the contract this season that there will be a $5 late fee if payment is not received on time. But some people still don't pay! Do I send out the bills again with the late payment fee tacked on or do I get on the phone with these people and talk to them personally? Any suggestions??
