Affirm
Affirm is a large general-purpose buy-now-pay-later and installment lender that pays merchants up front and assumes default risk, used by some med spas through Zenoti and Stripe-based POS rather than built for aesthetics.

The ubiquitous healthcare credit card, now AmSpa's exclusive partner
CareCredit offers unmatched acceptance and an exclusive AmSpa partnership, but its deferred-interest model, high merchant fees, hard-pull application, and poor consumer ratings make it a cautious choice rather than a default — best paired with clear patient disclosure.
CareCredit, issued by Synchrony Bank, is the long-established healthcare credit card used to pay for elective and aesthetic care. Accepted at a reported 250,000+ provider locations and now the exclusive financing partner of the American Med Spa Association (AmSpa) with preferred member merchant rates from January 2026, it offers the widest acceptance footprint of any option in the category. Unlike the newer aesthetics-built installment lenders, CareCredit is a revolving credit line: patients can reuse it across many providers, with credit limits up to about $25,000.
The critical distinction is its cost structure. The standard purchase APR is around 32.99%, with reduced-APR plans of 17.90–20.90% on longer terms, and heavily marketed deferred-interest promotions (0% if paid in full within 6, 12, 18, or 24 months on purchases of $200+). Those promotions charge **retroactive interest** back to the purchase date if the balance isn't cleared in time — a model that has drawn sustained consumer complaints and CFPB scrutiny of deferred-interest practices industry-wide. Patients prequalify with a soft pull but a full application triggers a hard credit inquiry. Practices are paid up front minus a merchant discount rate that ranges widely from about 1.9% to 14.9%, with roughly 10% common on the 0%-deferred plans. It integrates with Zenoti and PatientNow.
Ideal customer
Med spas that want the broadest patient acceptance and the AmSpa preferred-rate relationship, and whose patients may already carry a CareCredit card — provided staff can clearly explain the deferred-interest terms to patients.
CareCredit is the incumbent of healthcare financing. Issued by Synchrony Bank and accepted at a reported 250,000+ provider locations, it is the most widely held and widely accepted option in the category — many of your patients may already carry the card. As of January 2026 it is also the exclusive financing partner of AmSpa, with preferred merchant rates for members, which makes it impossible to ignore for med spas weighing the association relationship.
Unlike the newer aesthetics-built installment lenders, CareCredit is a revolving credit card. Patients get a reusable line with limits up to about $25,000 that works across many providers, not a single fixed-term loan tied to one treatment. That breadth is its defining advantage — and its structure is also where the trouble starts.
Choose CareCredit if breadth of acceptance and the AmSpa relationship matter most, and especially if many of your patients already hold the card. But go in clear-eyed: the deferred-interest structure, high merchant fees on 0% plans, hard-pull application, and poor consumer-satisfaction record make it a weaker default than aesthetics-built, no-deferred-interest options. If you offer it, train your front desk to explain the retroactive-interest terms plainly, and consider running a soft-pull installment lender alongside it.

Practices are paid up front minus a merchant discount rate that ranges widely from about 1.9% to 14.9%, with roughly 10% common on 0%-deferred-interest plans — markedly higher than the aesthetics-built installment lenders. AmSpa members receive preferred merchant rates from January 2026. Patients face a standard purchase APR around 32.99%, reduced-APR plans of 17.90–20.90%, and deferred-interest promos that charge retroactive interest if the balance isn't paid in full by the promo deadline. Soft prequalification; a full application is a hard credit pull.

Opening a med spa typically costs from the low six figures for a lean injectables studio to $500K+ for a device-heavy buildout. Here's a line-item 2026 budget walkthrough—equipment, injectables, buildout, legal, insurance, software, and marketing—plus the monthly burn and break-even math most guides skip.
A vendor-neutral guide to choosing patient financing for a med spa—covering why financing drives conversion, the six provider models, the deferred-interest trap, merchant economics, and how to match a provider to your patients.
Patient financing has no subscription - the practice pays a merchant discount fee (a % of each financed sale) and the patient pays APR or deferred interest. Here's a transparent 2026 breakdown of real merchant fees and patient rates by lender.

Afterpay, owned by Block (Square), is a mainstream buy-now-pay-later provider offering interest-free Pay-in-4 on smaller purchases. Some beauty businesses and med spas use it for retail and lower-ticket services, but it is not a healthcare-built financing product for higher-ticket aesthetic procedures.
