Recurring service is the schedule
In commercial pest control, most of next month is already decided. The monthly accounts recur, the quarterly accounts recur, and the work that has to be planned around them is the exception rather than the rule.
That inverts what a scheduling tool needs to be good at. The hard part is not creating a booking; it is keeping a standing set of obligations visible, spotting where coverage has gone thin, and making a change to a recurring pattern without hand-editing months of individual visits.
