How it works
Create an invoice or a payment link in the dashboard, send it to your customer, and they pay by card, ACH, or stablecoin from any device. The payment posts to your dashboard and books automatically.
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.
