Flux recurring billing charges subscriptions and memberships on autopilot, with automatic retries on failed payments, webhooks for subscription events, and secure card update links that recover revenue you would otherwise lose to expired cards.
Why businesses use it
Bills on autopilot
Charge memberships and plans on schedule without re-running cards by hand.
Recover failed payments
Automatic retries and secure card update links win back revenue lost to expired cards.
Simple plan changes

How it works
You define a plan and attach a saved payment method, and Flux charges it on schedule. Failed payments are retried automatically, webhooks report each charge, and a secure link lets customers update expired cards.
Simple, transparent pricing
Flux charges a flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume merchants and no setup fees or contracts. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee. You can also run a cash discount program, so customers who pay by card cover the processing fee.
