Okay getting back to the original question.
Say one was to bundle the following: all fertilizations, weed spot spraying, weekly mowing, aeration as needed. 5% off if the client pays with out being billed or prepays on a set date in the month. Advantage is fertilization doesn’t get skipped, lawn looks great, weeds in check etc. If you provide snow removal same amount every month all year.
Just makes sense to me. I believe it just has to be presented correctly.
