Pairs with Stormbox Wash Controllers · competitive processing rates
The pair
One takes the card. One runs the wash.
A Rain Pay terminal up front, a Stormbox Wash Controller behind the wall. Together they give you control coin boxes and standalone readers never could: change a price, a wash package, or a time increment in MonsoonOS, and it’s live at every terminal instantly.
The controller that runs the wash.
- Connects to most wash timers, not the equipment itself
- Runs self-serve bays, in-bay automatics, vacuums, vending, and dog wash stations
- Takes pricing, time, and package rules straight from admin
- Lock, unlock, or service any machine remotely

Common questions
Rain Pay FAQs.
The questions Cactus Wash Systems hears most from operators comparing Rain Pay to the card readers they have today.
- What is Rain Pay?
- Rain Pay is the integrated payment terminal from Cactus Wash Systems for self-service car washes and dog washes. It takes tap and swipe card payments right at the bay, and it is wired into MonsoonOS, the same platform that runs your pricing, subscriptions, fleet accounts, and promotions.
- What can customers do at a Rain Pay terminal?
- Pay for washes and wash time, start a subscription billed to a saved card, redeem promo codes and wallet passes, and run fleet washes with a personalized QR code and a 4-digit PIN. All of it happens on the terminal at the bay, no app required.
- How is Rain Pay different from a standalone card reader?
- A standalone reader only moves money. Rain Pay is part of the platform: pricing changes push to every terminal instantly, every transaction lands on one ledger tied to a customer record, and the terminal sells more than a single wash, with subscriptions, fleet washes, and promotions included.
- What are Rain Pay's processing rates?
- Competitive with the standalone card readers common in self-service washes, and the terminal comes wired into MonsoonOS instead of bolted on beside it. Exact rates come with the custom quote we build around your wash layout.
- Does Rain Pay work for dog washes?
- Yes. Rain Pay terminals run at self-serve bays, in-bay automatics, vacuums, and vending machines as well as dog wash stations. One payment platform across every wash type.
- Do I have to replace my wash equipment to use Rain Pay?
- No. Rain Pay pairs with Stormbox Wash Controllers, which connect to most wash timers in self-service car washes and dog washes. Your equipment stays; the timer gets smarter. The fastest way to confirm your setup is supported is to email Cactus Wash Systems.
