Flux gives crossfit boxes recurring card billing, hosted signup fields, and one integration for cards, ACH, and stablecoins so members can pay the way they want.

No long-term contract
Cancel anytime, with no setup fees and no contract while you grow.
How crossfit boxes get paid
CrossFit Boxes run memberships on recurring cards, take ACH for annual plans, and sign members up through hosted fields, all on Flux.
A typical Flux setup for CrossFit boxes
The membership is the engine: monthly billing to a stored card, started only after the athlete finishes a foundations or on-ramp course that is paid upfront as a single charge. Around that core sit drop-ins from traveling athletes paying card-present at the desk, punch cards for the occasional visitor, and apparel drops sold online. Competitions and in-house throwdowns collect registration through the same checkout, each athlete paying individually.
Because boxes tend to bill month to month rather than lock athletes into terms, Flux's own structure matches: no contracts, no monthly fees on qualifying card volume, no minimums. Membership charges settle in 1-2 business days, ACH is available for members who prefer bank billing, and QuickBooks sync keeps memberships, event registrations, and apparel separated so a big throwdown weekend does not distort the picture of recurring revenue.
What CrossFit boxes should watch
Holds are the retention lever. Athletes travel for work, get injured, or disappear for a season, and a box that makes them cancel to stop billing loses them for good. Pausing a billing schedule is one API call, the card stays on file, and the membership resumes when they walk back in. The alternative, cancelling and rebuilding the membership later, is where billing mistakes and awkward conversations come from.
Events and apparel carry the card-not-present weight. Competition registrations need a published policy for withdrawals and for the athlete who registers twice by accident, and refunds should go out fast because a fitness event charge is easy for a cardholder to dispute months later. Apparel pre-orders have a gap between charge and delivery, so state the ship window at checkout. Drop-ins at the desk are the easy part: card-present, small amounts, rarely contested.
Simple, transparent pricing
Flux charges a flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume crossfit boxes and the option to pass the fee to the customer at checkout where local surcharging rules allow. No setup fees and no contracts. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee.

How fast do crossfit boxes get their money?

Can I pause a member's billing for an injury or a long trip instead of cancelling?
Yes. The billing schedule pauses through the API, the card stays stored, and billing resumes on the date you set. The member never has to re-sign or re-enter payment details when they come back.
How do I collect registrations for a competition or throwdown?
Athletes pay individually through an online checkout using hosted fields, and the funds settle to you in 1-2 business days, well before event weekend. QuickBooks sync keeps event money separate from membership revenue.
Can a visiting athlete pay a drop-in fee without joining?
Yes. A drop-in is a simple one-time charge at the desk or through your site, with no account, stored card, or recurring schedule attached. Punch cards work the same way as a single upfront charge.
