More than a card reader

A terminal that talks to your operation.

A standalone card reader moves money and nothing else. Rain Pay is a payment device connected to operator software, reporting, memberships, and control workflows — so a payment can do more than open a valve.

Connected to software

Every transaction lands in MonsoonOS, tied to a customer record and your reporting instead of a separate box to reconcile.

Memberships & recurring revenue

Add card and app payment workflows, plus membership or recurring wash options, without bolting on a second system.

Reporting & control

Better reporting and remote control workflows, so you can see and manage bays, sessions, and revenue across locations.

Built for wash operators

One payment platform, every wash type.

Self-serve car wash

Card and app payments at self-serve bays, with remote start and reporting for compatible equipment.

Common questions

Rain Pay terminal FAQs.

Common questions from operators comparing Rain Pay to the payment setups they run today.

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 or implementation.
Can this work with older relay-based equipment?
Often, where the equipment can be started through a compatible control signal. Every site has different wiring, timers, and equipment, so this is implementation-dependent and confirmed 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.
