This customer used to hire me to aerate and power rake his lawn each year for many years. Last year he decided to have me perform full time maintenance on his property since he was too busy with his own concrete business. Last year I mowed, fertilized, etc... his lawn without any complaints. He was a late with his bill twice last year but I did not make a big issue since he was not a PITA. This year he asks me to mow same as normal but he does not want me using that "big ole mower" because it causes ruts. Now I am on this lawn every week and I know it does not cause ruts. I said OK but your weekly bill is going up a few bucks and he agreed. I started aeration, fert, mowing in April as planned. May comes and this fool is watering everyday for hours on end. I literally have to wear waders to mow and trim this guys lawn. The grass is growing like crazy and I politely leave him a not asking him to give the watering a rest for awhile. I usually leave a bill for every customer at the end of the month for services performed. I have been doing this for 4 years with no problems. Late May comes around and he has not paid his April bill and I figure no big deal I will just combine April and May and he will catch up. June 15th comes around and I still have not heard anything so I leave him a message to please let me know if there is any problems with finances because I have not been paid yet. No call back, NOTHING. I also mow the neighbors yard and she says this idiot is gone a lot and he wife is around once in awhile and I should approach her sometime. End of June comes around and I leave another bill with all 3 months invoices included. I also leave a note inside saying that no more servbices will be performed until I receive the full balance in full. It has been a few weeks since the last bill was sent and they still have not responded. The lawn is sitting there about 3 feet high and they are still watering everyday. Now I could kick myself for even mowing the 2nd part of June. I am going to send them a certified letter with invoices attached. Then I am going to send it off to collections. If nothing happens after that I will heading to court this off season. This one customer has me re-thinking how I do business. I am thinking of sending bills out on the first of the month for that month's mowing. Bills will be due by the 15th or no mowing will be performed after that date. I am also thinking about credit billing that I can charge after each mowing to try to alleviate some of these late payers. Just kind of wondering how you all bill out there.
