Article summary

TL;DR

Shopify's checkout is fast and trusted, and it suits most fitness stores. Its limits show up in three places: one card processor at a time, Shop Pay Installments only with Shopify Payments, and in-checkout customization only on Plus. Equipment brands feel the installment and delivery limits; sports nutrition brands feel the processor and subscription ones.

Shopify allows "only one credit card payment provider activated at a time"; a third-party one costs 2% on Basic down to 0.2% on Plus per order.
Shop Pay Installments needs "both Shopify Payments and Shop Pay activated" and covers US orders from $35 to $30,000.
Shopify Payments prohibits "Pseudo pharmaceuticals", products "that make health claims that are not verified" by a regulator.
Checkout UI extensions in the information, shipping and payment steps are Plus only.
Script tags on non-Plus Thank you and Order status pages stopped on August 26, 2026.

What a fitness brand needs from checkout

Need	In Shopify checkout	Note
Express payments (Shop Pay, Apple Pay, Google Pay, PayPal)	Yes	Built in
Pay over time on a $1,500 machine	Shop Pay Installments, with Shopify Payments only3	Other providers through payment apps
Freight or large-item delivery options	Shipping settings and Functions for delivery logic4	Functions on all plans except Starter
Order bumps (an accessory before payment)	Through apps; in-checkout blocks need Plus4	Non-Plus: before checkout or after payment
Post-purchase upsell	Thank you page blocks on all plans except Starter; post-purchase extension in beta4	Check with your app
Sports nutrition on subscription	Shopify Subscriptions or apps; limited gateways7	Check your processor is supported
A second card processor as backup	NoOne at a time1	Needs a checkout or payment layer outside Shopify's
Legal notices in checkout (Prop 65, age)	Product page on all plans; in the checkout steps, Plus only4	See below

Payments: Shopify Payments, a third-party processor, or both?

Equipment and accessories: Shopify Payments' prohibited list doesn't name fitness equipment6. Most equipment stores stay on Shopify Payments and keep Shop Pay Installments.
Sports nutrition: Shopify Payments prohibits "Pseudo pharmaceuticals": "Pharmaceuticals and other products that make health claims that are not verified by a local or national regulatory body"6. The risk sits in your claims and ingredients, not in the word "protein".
If Shopify Payments refuses or closes you, you can connect one third-party card processor1 and pay Shopify 2% on Basic, 1% on Grow, 0.6% on Advanced or 0.2% on Plus per order2. You also lose Shop Pay Installments, which requires Shopify Payments3.

Watch out

A brand that sells both a power rack and a pre-workout on one store is reviewed as one merchant. If the nutrition line gets the store moved off Shopify Payments, the equipment line loses Shop Pay Installments too. Splitting the lines into two stores is one option; check the processor rules for each before deciding.

Who accepts which products: can you sell fitness products on Shopify?

Selling equipment: installments and delivery

Equipment carts are large: Polar's "Sports & Outdoor" median order is $138.48 (August 2026)12, and a home gym order sits far above it. Two parts of the checkout carry most of the weight.

Pay over time
Shop Pay Installments covers US orders from $35 to $30,0003. Show the monthly amount on the product page, not only at checkout.
Delivery at checkout
Show the delivery method (parcel, freight, curbside, room of choice) and its price before the payment step. Extra costs are the top reason US shoppers abandon, cited by 40% in Baymard's survey13.
Address quality
Large items fail at the door. Ask for a phone number and delivery notes for freight orders.
Returns in one line
Link the return policy near the pay button, so buyers know how a 100-pound item goes back.

Recovering equipment carts that stall here: abandoned cart recovery for fitness brands.

Selling sports nutrition: subscriptions and legal notices

Subscriptions. Shopify Subscriptions works with Shopify Payments, PayPal Express, Authorize.net, Adyen and Stripe (Stripe "available only to select merchants")7. Subscription apps have their own lists.
Prop 65. For internet purchases in California, a required warning goes on the product page, or behind a link marked "WARNING" on that page, or is shown before the purchase is complete; it is not prominently displayed if the buyer has to search for it8. On non-Plus plans, put it on the product page, since you can't add blocks in the checkout steps4.
Age. New York bans the sale of weight loss and muscle-building supplements to minors and requires proof of age at delivery9. That is handled by your carrier and delivery settings, not only by a checkbox.

These rules decide whether a product can be sold; the billing side is in subscription billing for fitness brands.

Summary of the table above.

Shopify's Terms of Service, updated October 20, 2026, ask merchants "not to work around, bypass, or circumvent any of the technical limitations of the Services, including to process orders outside Shopify's Checkout"10.

Read them, and ask Shopify or your counsel how they apply, before you send Shopify traffic to an outside checkout. A store that runs fully on a standalone platform is not under these terms.

Frequently asked questions

Can I sell fitness equipment with Shopify checkout?

Yes. Shopify Payments' prohibited list doesn't name fitness equipment, and Shop Pay Installments lets US buyers pay orders from $35 to $30,000 over time, as long as you use Shopify Payments. Show delivery costs and the return policy before the payment step.

Can I sell protein powder and pre-workout with Shopify Payments?

Shopify Payments doesn't name them. It prohibits "Pseudo pharmaceuticals", products that make health claims not verified by a regulator. The review looks at your claims and ingredients. If you're moved to a third-party processor, Shopify adds a 0.2% to 2% fee per order.

Can I offer financing on my Shopify fitness store?

Yes, with Shop Pay Installments if you use Shopify Payments and Shop Pay, for US orders from $35 to $30,000. On a third-party processor, you need a separate installment provider that works with Shopify checkout.

Can I add an order bump to Shopify checkout without Plus?

Not inside the information, shipping or payment steps: those UI extensions are Plus only. On other plans, offer the accessory in the cart or after payment, on the Thank you page, or use a checkout that supports bumps.

Can I use two payment processors in Shopify checkout?

Not for cards: Shopify allows only one credit card payment provider at a time. Wallets and some alternative methods can run alongside it. A backup processor or routing needs a checkout or payment layer outside Shopify's own.
