How it works
You define a plan and attach a saved payment method, and Flux charges it on schedule. Failed payments are retried automatically, plan changes are prorated, and dunning emails nudge customers to 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 pass the processing fee to the customer at checkout where local surcharging rules allow.
