Aquarium services
Water changes, media swaps, testing and algae control already run on a cycle. Set the interval, the size bands and the travel radius once, and the repeat visits book themselves.
Generic booking tools treat every job as one hour in one place. A service round is neither.
A 20-gallon community tank and a 180-gallon reef are not the same visit. Set bands by gallons and by water type so the calendar stops underselling the big jobs.
Weekly, every other week, or monthly. The same slot stays with the same tank until someone cancels, so a round builds instead of resetting every month.
Nitrate, phosphate, alkalinity, salinity, and the date media was last changed. Logged against the tank rather than remembered, so cover visits are not guesswork.
A failed heater or a sudden bloom is not a routine visit. Give emergencies their own rate and their own window so one bad tank does not wreck the day's schedule.
What a standing visit covers
List the visit once, in the language owners actually understand, and it stops being a quote every time.
Nothing. Recurring visits, callouts and pond work all pay out in full, and there is no charge for the calendar itself. Livestock and plants are never handed to a courier, so anything alive stays pickup-only or goes in your own vehicle.
