This is the first time i have had any problems in 6 yr with a customer. anyway I have a customer which owes me roughly $450 dollars now about 2 months of lawn maintinance. Anyway this particular customer paid on time great last year and everything but lives in a different state about %80 of the time. Anyway i am looking for a little advice on what i need to do to win a successful case. Basicly what i have done so far i can prove that she authorized the work. I have sent her 3 invoices and recorded dates sent also called her 3 times and left voice mails with my name and number recoded time called and date called last voice mail i left and invoice i sent informed her that service has been suspended untill the bill is paid in full. She also left me her mothers # incase i would notice something around the house while she was gone that i needed to contact someone in town with. Recorded that date and time and left a voice mail and no return on that phone call. I feel that i have gone above and beyond to contact the customer. The only thing that i can think of that i have not done is send a certified letter. Is that really needed? Basicly is there anything else in need to have to cover my end of the deal in court?
