A maintenance plan says "this system needs this service every so often". AquaOps then books each visit ahead of time and moves the due date on when the job is done.

A visit is booked late, or not at all, and the customer notices before you do. ### Plans per system Choose the system, the service, how often (days, weeks, months or years) and the usual technician. ### Auto-booked visits The next job is created a number of days before it is due, so the calendar fills itself. ### Customer reminders Warranty ending, service due and consumables due: customers are told once per step, at the days you choose. ### See what is overdue One list shows what is due, overdue and coming up, with the technician and the linked job. ### Repeat this service Turn a one-off job into a plan from the job itself, for the services where repeating makes sense. ### Pause and restore Pause a plan when a contract is on hold and restore it later. Nothing is deleted.

Questions ## About maintenance plans and reminders **### Can I choose which services repeat?** Yes. Each service type has a setting for whether it can repeat. By default maintenance, inspection and water tests can; installation, repair and emergency cannot. **### Can one system have several plans?** Yes, for example a quarterly filter change and a yearly membrane service. The screen shows the existing plans before you add another. **### Who gets the reminders?** Customers only, and each reminder is sent once per step. Which reminders are on and how many days before is your setting. ## Works together with [Jobs and schedulingBook, assign and follow every service visit, from the first request to the closed job.](https://aquasops.com/features/job-management)[Customer portalYour customers see their visits, invoices, documents and open tickets, and can pay online.](https://aquasops.com/features/customer-portal)[Water quality readingsRecord readings on every visit and see at a glance which systems are in range and which are not.](https://aquasops.com/features/water-quality) ## See it with your own kind of work Book a short demo.
