Payments for Yoga & Pilates Studios: What Stripe, Square, and the Big Processors Actually Cost You

The short version: studios run on recurring memberships and class packs — which means card-on-file billing at stored-card rates, and a fee table that looks very different from a coffee shop's. On a $220 unlimited membership, the wrong stored-card rate costs you an extra $1 per member per month; at 150 members that is $1,800 a year. Here is what Stripe, Square, and the big processors actually cost a yoga or Pilates studio. Also see Yoga & Pilates Studios, AI for Yoga & Pilates Studios, and Tech for Yoga & Pilates Studios.

The fee table: dues are the business

Rates checked October 2026. Square: 2.6% + 15¢ in-person, 2.9% + 30¢ online, 3.5% + 15¢ keyed/stored. Stripe: 2.7% + 5¢ in-person, 2.9% + 30¢ online, 3.4% + 30¢ stored; ACH 0.8% capped at $5. Interchange-plus: ~0.3% markup, effective ~2.0% card-present.

$25 drop-in (reader): Square $0.80 · Stripe $0.73 · Interchange-plus ~$0.50

$180 10-pack (online): Square $5.52 · Stripe $5.52 · Interchange-plus ~$3.70 · ACH $1.44

$220/mo unlimited (stored card, monthly): Square $7.85 · Stripe $6.68 · Interchange-plus ~$4.50 · ACH $1.76

$220/mo × 150 members = $33,000/mo in dues: Square stored $1,177.50/mo ($14,130/yr) · Stripe online $1,002/mo ($12,024/yr) · Interchange-plus ~$675/mo (~$8,100/yr) · ACH ~$264/mo (~$3,168/yr)

The dues row is the business: Square versus ACH is a $10,962/yr gap on the same $33,000 in dues. Per member per year: $94.20 in fees on Square stored-card versus $21.12 on ACH. The $25 drop-in row shows the other end — small tickets where the 15-30¢ fixed fees dominate, and where interchange-plus's lower fixed fee wins outright.

The break-even: ACH wins dues; the fight is over the rest

For dues, ACH wins at every volume — there is no break-even to compute, only a migration to execute. The break-even that matters is on the card volume that remains (drop-ins, packs bought by card, retail, workshops).

IC+ plans carry ~$10-25/mo in fixed costs. At $6,000/mo in card transactions: Square in-person costs ~$165. Interchange-plus at ~2.0% costs ~$120 + ~$20 = ~$140. At $12,000/mo: Square ~$330; IC+ ~$240 + $20 = ~$260. The flip is around $8,000-10,000/mo in card volume — most 100+ member studios clear it on packs and drop-ins alone, before dues are counted.

The retreat row deserves its own math: a $1,200 retreat paid by card costs $35-42 in fees; by ACH, $5. Ten retreat spots a month is $300-370/mo in avoidable fees. Invoice retreats and workshops with ACH as the default. Clients paying $1,200 for a weekend do not flinch at a bank transfer.

The workflow checklist the big processors fail

Run every processor against this checklist before you sign:

• Recurring membership billing at sane stored-card rates. Square's 3.5% + 15¢ stored rate is the most expensive dues billing in this guide — $94.20/yr per member on a $220 membership. If the platform cannot do better than that on stored cards, it is not a studio platform.
• ACH for dues. 0.8% capped beats every card rate 4-5x. Default every signup flow to bank draft; offer cards as the convenience option.
• Dunning automation. Day-zero failed-payment text with a card-update link. Worth more than 0.2% of rate — the recovery math is in the AI guide.
• Pack tracking tied to billing. The $180 10-pack needs per-class redemption tracking married to the payment record — "classes remaining" must be real data, not a guess, or the expiry texts from the AI guide cannot fire.
• Intro-offer billing. The $49 two-week intro is a distinct SKU with its own expiry and conversion tracking. If the system cannot tell you intro-to-membership conversion by teacher, it cannot run the business.
• Workshop and retreat invoicing. Large one-off charges ($300-1,200) with ACH as the default rail — and without triggering the risk holds that flat-rate aggregators put on outlier transactions.

The honest verdict on each processor

Square — wrong-shaped for memberships. Fine for drop-ins and retail at the counter. But dues at 3.5% + 15¢ stored is the priciest membership billing here — $14,130/yr on 150 members versus $3,168 on ACH. Steelmanning Square: zero monthly cost, simplest countertop for a new studio's first 90 days.

Stripe — good pipes, no studio. Excellent ACH (0.8% capped) and card APIs — but no dunning, no pack tracking, no intro-conversion anything out of the box. You build the studio on the pipes. Custom software material only.

Interchange-plus via a studio-savvy provider — the quiet winner. ~2.0% effective on card volume, ACH for dues, real dunning. The catch: you assemble it, and the sales process involves a human quoting you.

Platform-bundled processing (Mindbody, Mariana Tek, etc.) — convenient, inspect the rate. Bundled billing is one throat to choke, but the effective rate on stored cards is often 2.9%+ — fine, as long as you price it against the DIY math instead of assuming it is competitive.

Adyen, Chase Payment Solutions, Fiserv, Global Payments, Worldpay — absent. Quote-based enterprise sales, zero studio-specific content: nothing on memberships, packs, or dunning. Not competing for your business.

How a studio actually wires this up: notes from Finix's public docs

ClaroPro pairs bilingual voice-to-agreement with payments — the post-class close (speak the unlimited, text the agreement, signed before she reaches her car) runs on one system.

For the billing plumbing, Finix's public docs map directly onto studio needs. Recurring billing primitives for monthly memberships with proration and retry schedules you control; ACH transfers as the default dues rail at 0.8% capped; tokenized payment instruments for card-on-file packs and drop-ins; webhooks on failed payments that trigger the day-zero dunning text; and separate merchant accounts per location so location two's launch does not re-trigger risk review on location one. Standard infrastructure documented at docs.finix.com. Knowing these are commodities is how you judge whether a studio platform's billing is real infrastructure or a markup wrapper.

FAQ

Should dues go on ACH? As many as possible. A small bank-draft discount ("$215/mo on ACH vs $220 on card") moves members fast — the $5/mo you give up saves far more in fees.

What about members who insist on cards? Take the card — a paying member at 2.9% beats a lost member at 0%. Default to ACH first.

Can I surcharge credit cards on memberships? State-dependent and stricter for recurring billing. The ACH discount is cleaner in every state.

How do I handle the member who disputes three months of dues? The signed membership agreement, the attendance record, and the confirmation texts are your three documents. Processors side with the studio that has all three.

Do retreat payments need their own setup? Invoice them with ACH as the default rail — large one-off card charges are exactly what triggers risk holds on flat-rate aggregators.

The order: 1) memberships and packs on a processor with sane stored-card rates — or ACH where members accept it. 2) Dunning texts on every failed draft. 3) Interchange-plus above ~$8k/mo in card volume. 4) Retreat and workshop payments on invoicing with ACH as the default.
