You give a quote to a commercial client for full service maintenance. Your bid states that all bushes will be trimmed twice that season, and that all beds will be mulched as well. The per time price for each service is stated. The customer signs and agrees to everything. My question is do you wait for them to tell you when to trim the bushes and do the mulching, or do you just do it when you think of it anytime during the season? Thanks!
