Had this couple for two years now, both Attorneys, woman off work though due to young child at home. They have usually done fairly well when it comes time to pay up. This year the woman has called me several times requesting leaf clean-ups, pulling bushes and planting begonias in addition to the regular mowing we do. I have always billed them at the end of the month with 30 days terms (changed new customers to 15 now). They have recently purchased a home for his father and she is driving a new escalade. So far this year Ive received nothing for Half of March, all April and May. Sent late statement, talked to her while at her home a week ago and now I have called and left two messages and they aren't returning the call. Monday I will be sending a certified letter requesting payment in full and letting them know that Ive canceled there service and plan the file in small claims if this is not resolved promptly. This will be the first time ever in 12 years in the biz I will have to sue. Ive been very fortunate that Ive had such good customers in the past that I seldom have had any problems collecting, but I guess it has to start somewhere.
