A maintained asset is an asset with a PM plan, a certification or a meter. Everything else in your register is free.
That distinction matters when your register holds more than the machines in daily service. Count the assets that have one of those maintenance records, rather than assuming every item on your equipment list adds to the bill. A parked machine still counts if it has a PM plan, a certification or a meter. Where it is standing does not change that definition.
Pro includes unlimited users. Adding a mechanic or operator does not add another user charge. Check the homepage pricing section for current plans, starting prices and asset allowances. Those details come from the same pricing configuration used across the site.
