If you're selling coaching online, payment processing is not back-office trivia. It directly affects conversion. Baymard's latest cart abandonment roundup, updated September 2025, puts average online cart abandonment at 70.22% across 50 studies. That does not mean payment is the only problem, but it does mean every bit of checkout friction matters. If your payment flow feels sketchy, forces the wrong method, or breaks recurring billing, you lose revenue you already earned. Source
What actually matters for coaches
Most coaches do not need a "finance stack." They need four things: reliable checkout, recurring billing, low admin overhead, and payment options clients already trust. Stripe says its standard platform supports 100+ payment methods, 135+ currencies, and reports 99.999% average historical uptime. That matters if you coach internationally or want subscriptions, payment links, invoices, and automations under one roof. Source
PayPal and Square matter for a different reason. They are familiar. Familiarity reduces hesitation, especially when a client is paying you for the first time. So the real decision is not "which processor is cheapest?" It is "which processor matches how I sell?"
Stripe is the strongest default for online coaching
For most solo coaches selling packages, retainers, or monthly programs, Stripe is still the cleanest default. The reason is not hype. It is infrastructure. Stripe's pricing page says its standard plan has no setup fees, monthly fees, or hidden fees, and bundles checkout, payment links, invoicing, recurring billing, and multi-currency support into one system.

That matters because coaching offers often evolve. You might start with 1:1 sessions, then add a 3-month package, then a recurring community, then an upsell after week 4. Stripe handles that progression better than most simple processors because billing and automation live in the same ecosystem. If you want a payment link in DMs, an invoice for a corporate client, and a subscription for ongoing support, Stripe fits all three without duct tape.
Best fit: online-first coaches, international coaches, and coaches who want recurring billing or automation.
PayPal is worth offering when trust is the bottleneck
PayPal's US merchant fee page, last updated February 9, 2026, lists PayPal Checkout at 3.49% plus a fixed fee for domestic commercial transactions. Source
That rate is not the cheapest option in this comparison. But price is not the whole story. PayPal is still useful when buyer trust is fragile. If a prospect has never paid you before, already has a PayPal account, and wants a familiar branded checkout, PayPal can reduce hesitation at the last step.
The catch is operational simplicity. If PayPal becomes your only processor, your stack can get messier once you add subscriptions, automations, or more advanced reporting. For many coaches, PayPal works best as a secondary option, not the core system.
Best fit: newer coaches who want a recognizable checkout option, or coaches selling lower-ticket offers to colder traffic.
Square is strongest if you sell both online and in person
Square's fee page is unusually clear. It lists 2.6% + 15¢ for in-person card-present payments, 2.9% + 30¢ for online payments, and 3.3% + 30¢ for manually entered cards or invoice payments. Source
That pricing structure tells you exactly who Square is for. If you run in-person sessions, workshops, or hybrid coaching with occasional face-to-face payments, Square makes sense. Its card-present rate is better than its invoice rate, which is what you would expect from a platform built with physical payments in mind. Source
But if your business is mostly remote and subscription-heavy, Square is less compelling as the main engine than Stripe. It can still work. It is just not the obvious first pick for a coach whose whole delivery model lives online.
Best fit: fitness coaches, local business coaches, workshop-led offers, and hybrid coaching businesses that collect in-person payments.
The practical recommendation
Here is the simplest answer.
Use Stripe as your main processor if you are an online coach and want the fewest future headaches. Its combination of recurring billing, invoices, payment links, global payment support, and uptime makes it the strongest default for most service businesses. Source
Offer PayPal as a backup option if your audience is cold, international, or trust-sensitive. The fee is higher on the standard US checkout rate, but a familiar payment brand can still rescue deals that would otherwise stall. Source
Use Square first if your coaching business regularly takes in-person payments. Its card-present rate is the strongest of the three and its pricing page is built around that use case. Source
If you want the shortest version: online coaching equals Stripe first. Hybrid coaching equals Square consideration. Trust-sensitive checkout equals add PayPal.
Final takeaway
A lot of coaches waste time obsessing over logos, checkout colors, or tiny fee differences while the real issue is mismatch. Your payment processor should match how you sell. If your offer is recurring, online, and international, optimize for billing flexibility and reliability. If you sell in person, optimize for card-present payments. If your buyers hesitate, give them a trusted fallback.
