Intervals depend on water quality and usage, so allow adjustment per customer. People search "RO filter change reminder" because missing the date means poor water and angry customers. For you it also means lost repeat revenue. ## RO filter change reminder: What the system must hold - Each purifier: model, install date, warranty. - The last filter and membrane change dates. - An interval per service (adjustable per customer's water). ## The routine - On the first of the month, list purifiers due in the next 30 days. - Message each customer with a booking link or time options. - Create the visit as a job and assign a technician. - After the visit, record what was changed; the next due date resets. ## Use it to sell the AMC A customer paying for a second filter change is a good AMC prospect: one price, scheduled visits, no surprises.
