We offer three different frequencies to lawn mowing: -Weekly -Bi-weekly -As needed Weekly and biweekly are concise definitions. However, "as needed" I have been having issues with because it is so vague. Because in Rhode Island, it is generally slow the last 2-3 weeks of April, grows like crazy until end of July, then slows in August with the heat, speeds up a little in September and slows again in October and November. So the majority of customers will need weekly cutting during the peak months but can go bi-weekly during droughts or the slower months. The problem I am having is defining this to my customers and employees in a concrete, concise manner, in order to set expectations for employees and on contracts for customers. What I put last year was "As needed (weekly May-Sept, bi-weekly April & Oct-Nov, weather dependent)" but I was not satisfied with this definition, it was still too vague. Maybe I need to put a # of cuts figure in there too? Any ideas?
