I was considering on offering full season packages to my customers. I have around 110 residential accounts.This would consist of Lawn maintenance (26 cuts), snow removal(10-15 plows), fall OR spring clean-up, 1 time Mulching and bush trimming offered for a set price. The majority of them at least want 3 of the 5 services offered. I would want half of the total price up front then the remainder would be paid on a monthly basis for 12 months. Good idea or no?
