Rain Pay terminal FAQs.

Is Rain Pay only for car washes?

No. Rain Pay terminals are built for unattended wash environments generally: self-serve car wash bays, dog wash stations, vacuums, and compatible relay-based equipment. The same operator software runs across every wash type.

Can it work with dog wash machines?

In many cases, yes. Compatibility depends on the specific machine and how it is controlled. The best next step is to book a demo and describe your current dog wash equipment so we can evaluate fit.

Do I need to replace my timer?

Not necessarily. Rain Pay pairs with Stormbox controllers designed for retrofit environments, which connect to compatible timers and relay-based workflows. Whether your specific timer is a fit is evaluated before any quote.

Can this work with older relay-based equipment?

Often, where the equipment can be started through a control signal. We confirm it during a discovery conversation.

Can I use this across multiple bays or machines?

Yes. Operators run Rain Pay across multiple bays and machines, and MonsoonOS supports multi-location operations with per-location reporting and employee access.
