Flux gives med spas cards, ACH, and recurring billing through one integration, with hosted fields and SAQ-D Level 2 PCI coverage that keep sensitive data off your practice systems.
Why med spas choose Flux
PCI coverage without the burden
Card data is captured in origin-isolated iframes, so your practice is not running an audited card environment.
Recurring and plan billing
Charge memberships and payment plans automatically instead of re-running cards by hand.
Predictable settlement
Card payments settle in one to two business days so the practice is not waiting on cash flow.
How med spas get paid
Med Spas typically take cards for copays and treatment fees by payment link or card on file, ACH for larger balances and plans, and can run recurring charges for memberships, all through Flux.
A typical Flux setup for med spas
Med spa money moves in three shapes: the booking deposit, the day-of balance, and the package. Deposits are charged by payment link when the appointment is made. The day-of balance is charged to the card on file at checkout or sent as a payment link the client pays on their own phone, so the front desk is not chasing balances after the client leaves. Series packages, six laser sessions or a filler program, are sold up front as one charge or as scheduled installments on a stored card.
Monthly memberships that bank credits toward treatments bill automatically, and retail skincare can ride on the same card-on-file charge or payment link. Every charge lands in the transaction record, so the front desk reconciles the day from reporting rather than a paper log. Cards settle in one to two business days, and QuickBooks sync separates service revenue, retail, and memberships so the books reflect what actually happened at the front desk.
What med spas should watch
Aesthetic services draw disputes months after the sale, usually against packages: a client three sessions into six decides the treatment is not working and disputes the original charge. Your defense is a usage log tied to the purchase, signed consent that describes realistic outcomes, and a refund policy in the sale paperwork. Refund unused sessions on your own terms before the client reaches for the issuer, because a partial refund you control beats a dispute you might lose.
Membership programs accumulate liability: banked credits are services you owe. Track the balance per member and state in the agreement what happens to unused credits at cancellation, because silent expiration is where complaints start. On deposits, charge them as real transactions with written forfeiture terms rather than holding card numbers for later, and never key a stored number manually; charge the stored credential through the platform so the paper trail stays intact.
Simple, transparent pricing
Flux charges a flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume med spas and the option to run a cash discount program so customers who pay by card cover the processing fee. 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 should a med spa handle tips for injectors and aestheticians?
Set the tip policy before clients ask, and log each tip in your practice software as it comes in, so payroll pulls the amounts from one record rather than reconstructing them from paper receipts. If you want tipping built into how clients pay, the Flux team can talk through your billing needs.
What is the best way to sell a multi-session package?
Either one up-front charge or scheduled installments on a stored card, with the session count, expiration, and refund terms in the signed purchase agreement. Log each session against the package as it is used; that usage record is your evidence if the purchase is ever disputed.
What happens if a client disputes a package they have partly used?
The dispute typically targets the full original charge, so your response is the signed agreement plus the session log showing what was delivered. Practically, offering a refund of the unused sessions before the client goes to their bank resolves most of these on your terms instead of the issuer's.
