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.

Rain Pay · at the bay

The terminal your customers see.

  • Tap or swipe any card, with no app, coins, or tokens
  • Sells washes and wash time on-screen, with a QR code to join a plan in the app
  • Scans fleet QR codes and takes the 4-digit PIN
  • Redeems promo codes and wallet passes at the machine
Stormbox · behind the wall

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
What it sells

Every way to pay. One terminal.

Tap or swipe

Contactless tap and swipe payments at the bay, station, or vacuum, fast enough that nobody reaches for quarters.

Competitive processing rates

See how pricing works

Subscriptions in the app

The terminal shows a QR code to download the app (iOS and Android), where customers start a plan billed to a saved card that renews automatically.

Fleet washes

Members scan a personalized QR code, enter a 4-digit PIN, and wash on account, with one consolidated invoice at month end.

Promotion redemption

Coupons, free washes, and wallet passes redeem right on the terminal screen. Every redemption counted, not guessed at.

Wash on Demand & online store

Per-wash purchases and online store orders ride the same rails, and everything reconciles on the MonsoonOS ledger automatically.

Why integrated

More than a card reader.

Bolting a card reader onto a coin box gets you card payments and nothing else. Rain Pay is the front door to the whole platform.

A bolted-on card reader

Takes payment. Knows nothing.

  • Takes a payment, but knows nothing about your wash
  • Separate tooling for subscriptions, or none at all
  • No fleet accounts, no consolidated billing
  • Promotions mean paper coupons and punch cards
  • Another dashboard to reconcile against your revenue
  • Price changes mean a site visit and new stickers
Rain Pay + MonsoonOS

One terminal. One ledger.

  • Tap or swipe, priced by your wash rules
  • A QR code on the terminal to join a plan in the app
  • Fleet washes with a QR code and PIN, invoiced monthly
  • Coupons, free washes, and wallet passes redeem on-screen
  • Every transaction on one ledger, tied to a customer
  • Competitive processing rates, quoted straight

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, redeem promo codes and wallet passes, and run fleet washes with a personalized QR code and a 4-digit PIN, all on the terminal with no app required. To join a subscription, customers scan the QR code on the terminal to download the app (iOS and Android) and sign up there.
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 does more than a single wash, with fleet washes and promotions on-screen and a QR code that sends customers to the app to join a subscription.
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.
