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.

Mainstream BNPL best suited to lower-ticket aesthetic add-ons
A trusted, comparatively transparent BNPL that pays you up front — but small caps, a hard pull on longer plans, a ~6% fee, and no aesthetics focus keep it to low-ticket add-ons rather than serious treatment-plan financing.
Klarna is a global, retail-first buy-now-pay-later provider that some salons and med spas use at checkout. Its short-term Pay-in-4 product is interest-free and runs a soft credit pull with an instant decision, while the practice is paid up front. That makes it a tidy fit for **lower-ticket aesthetic add-ons** — a facial, a single skincare purchase, a small package — rather than four- and five-figure treatment plans.
The caps and credit mechanics are the catch. Pay-in-4 covers roughly $30 to $1,000, and longer monthly financing (0%–24.99% APR over 6–36 months, minimum around $299, capped near $10,000) can trigger a **hard credit inquiry**, which is a harder sell to a patient than a soft pull. Klarna is not built for aesthetics; it reaches the category natively through **Aesthetic Record** and **Zenoti**, and through **Stripe** for platforms like Mangomint. Merchant fees are relatively transparent for the category — about 5.99% + $0.30 per transaction, falling toward 3.29% + $0.30 at very high volume — but via Aesthetic Record's Stripe path the effective rate lands around a flat 6.1%.
Ideal customer
Med spas and salons that want a mainstream BNPL brand for lower-ticket treatments and retail add-ons, and that can accept small financing caps and a possible hard pull on longer plans.
Klarna is a mainstream, retail-first BNPL provider that some salons and med spas run at checkout. Its sweet spot is lower-ticket work — a facial, a retail skincare purchase, a small package — rather than the four- and five-figure treatment plans that dedicated medical lenders are built for. The mechanics owners care about are there on the short-term product: interest-free Pay-in-4 with a soft pull, an instant decision, and the practice paid up front.
Where it gets awkward is scale and credit. Pay-in-4 caps around $1,000, and longer monthly financing (0%–24.99% APR, up to roughly $10,000) can trigger a hard credit inquiry — a tougher conversation with a patient than a soft pull. Klarna is not an aesthetics product; it reaches the category natively through Aesthetic Record and Zenoti, and via Stripe for platforms such as Mangomint.
Choose Klarna if you want a recognizable BNPL brand for lower-ticket treatments and retail, you already run Aesthetic Record, Zenoti, or a Stripe-based POS, and you can live with small caps and a possible hard pull on longer plans. If your financing need is large treatment packages or membership plans, this is the wrong tool — look to dedicated medical lenders. Disclose patient APRs clearly and model the ~6% fee against the margin on the items you expect to finance.

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.
