Payment Processors Compared for High-Risk Ecommerce: Stripe, PayPal, Shopify and Square

Stripe, PayPal, Shopify Payments and Square compared for high-risk ecommerce: bans, reserves, payouts, closures, card export and subscriptions.

Nick Bonnassies, CMO at Tagada · checked against 26 sources

Article summary

TL;DR

None of the four publishes a high-risk program. Each one opens your account fast, then reviews you on live payments, and each can hold funds or close the account under its terms. They differ on what they ban, how long they hold money, and whether your saved cards can leave. Pick by what you sell; keep a second, declared processor.

Stripe's list was updated September 22, 2026; Square's terms July 30, 2026; PayPal's user agreement September 14, 2026; PayPal's Acceptable Use Policy dates from October 29, 2022.
In the US, Shopify Payments runs on Stripe and PayPal, and their lists decide what it prohibits.
PayPal can hold a balance "for up to 180 days"; Stripe typically pauses payouts 120 days after a risk action.
Stripe and Square export saved cards to a PCI DSS Level 1 processor; we found no published procedure for Shopify Payments.
Square lists "direct marketing or subscription offers or services" among the 31 businesses it doesn't support.

How the four treat high-risk businesses

All four work the same way: sign up in minutes, get reviewed later. Stripe says it may support listed businesses only after review; PayPal asks for pre-approval; Shopify and Square simply say no to listed categories1 8 12 21.

	Stripe	PayPal	Shopify Payments (US)	Square (US)

Verdict

Stripe gives the most published detail and a real approval path. PayPal has a formal pre-approval list. Shopify Payments adds its own exclusions on top of two processors. Square's list names the most ecommerce sales models.

What each one prohibits or restricts

Every list is "representative" or "not exhaustive". A business that isn't named can still be refused1 12 13.

Stripe prohibits by category and restricts others, such as "Telemedicine and telehealth services" and "Online pharmacies, including SaaS platforms", which need approval first1.
PayPal prohibits some activities and requires pre-approval for others, including "Prescription Items", "Telemedicine Services" and "Multilevel Marketing and Direct Selling Organizations"8.
Shopify Payments excludes six categories, including "Pseudo pharmaceuticals", and "certain business models that, while legal, Shopify Payments can't support"12.
Square names 31 businesses it won't process, from pharmacies that fill medication after an online consultation to "up-sell merchants"21.

The full side-by-side, category by category, with each policy quoted: prohibited businesses by payment processor. Each processor's own list: Stripe, PayPal, Shopify, Square.

Shopify Payments Terms of Service (US) and Payment Processor List, read November 3, 2026.

Shopify's terms say prohibited categories "are provided by each Payment Processor in your Designated Country"13. Its processor list names Stripe, Inc. and PayPal, Inc. for the United States14.

Reserves and holds

A reserve holds part of your sales for a set time. A hold freezes money until a review ends. All four can do both2 9 15 21.

Processor	What it publishes	How long	How to contest
Stripe	Fixed and rolling reserves	"Normally" 30 to 90 days; "in some rare cases" indefinite2	Appeal from the Balance page2
PayPal	Rolling and minimum reserves; example "10% and held for a 90-day rolling period"9	Balance holds "for up to 180 days" on a risk or policy issue9	Resolution Center or the email notice9
Shopify Payments	"a 10% reserve for 120 days" as its example15	Set in the notice; can change "at any time, for any reason"13	Reply to the reserve email in time15
Square	"We may require a Reserve for any reason related to your use of the Services"21	NoLength in the terms; can be "raised, reduced or removed at any time"21	Through the deactivation notice, if it allows an appeal23

Watch out

PayPal's 180 days can run longer "according to Court Orders, Regulatory Requirements, or Other Legal Processes"9. Read the notice before you plan cash around a date.

How reserves are calculated and released, across processors: rolling reserves.

Payout timing

Know the normal delay so you can spot a hold. These are the published timings, not guarantees.

Processor	Normal timing	First payout or new account
Stripe (US)	Card payouts in 2 business days5	Typically 7 to 14 days after the first live payment5
PayPal	Money lands in your PayPal balance; a risk hold "generally" lasts up to 21 days9	New sellers are named among common hold cases9
Shopify Payments	As little as 1 business day to Shopify Money; up to 5 to an outside bank, plus up to 3 for the bank16	"payouts for new merchants can take up to 5 business days"16
Square (US)	Payout started at the end of each business day; Friday proceeds on Sunday21	Not stated in the terms

PayPal may release a hold early "if you've uploaded shipment tracking information", at its discretion9. More on settlement and delays: payout schedules and settlement times.

Reviews and closures

Each agreement lets the processor end the relationship without a stated cause. What changes is what happens to the balance.

Square may terminate your use of the Payment Services at any time for any reason.

Square, Payment Terms (US), section 37, last updated July 30, 2026

Stripe: "Stripe may terminate this Agreement or close User's Stripe Account at any time"3. On an unacceptable risk action, payouts are typically paused "for 120 days from the date the User receives the initial email"4.
PayPal: it can suspend or terminate "for any reason and at any time upon notice to you"9. On a restricted activity, it can also hold the balance up to 180 days9.
Shopify Payments: Shopify "may terminate this Agreement and close your Shopify Payments Account at any time, for any reason, upon notice", and a processor "may elect to continue to hold any funds deemed necessary"13.
Square: it "may defer payout or restrict access to your Proceeds, temporarily or indefinitely" during an investigation21. Appeals, when the notice allows one, are "typically reviewed within 48 hours"23.

The full recovery plan for any processor: merchant account closed and funds held.

Can your saved cards leave?

This decides whether a closure costs you a week or your subscriber base. Stripe and Square publish a procedure; PayPal publishes one for Braintree only.

Processor	Procedure	Where the cards can go	What doesn't move
Stripe	Request from the Dashboard6	"another PCI DSS Level 1-compliant payment processor"6	Subscriptions, payment history, cards saved with Link6
PayPal (Braintree)	Braintree exports the vault, in "no more than two exports"10	A provider with an attestation of PCI compliance10	"subscription or transaction information"; Apple Pay and Google Pay10
Shopify Payments	None published. Shopify staff, July 2022: "we are not able to transfer payment details"17
Square	Account owner calls Square Support22	"another PCI DSS Level 1-compliant payment processor"22	Everything except card data; "up to two weeks" on average22

We found no export procedure for cards used through PayPal checkout or PayPal Subscriptions. Plan your vault before you need it: how to switch payment processors.

Subscriptions and free trials

All four sell a subscription tool. Their rules on how you sell it differ.

Processor	Tool	Line that matters
Stripe	Stripe Billing; trial reminder 7 days before the end7	Prohibits "Negative option marketing, negative option membership clubs, and reduced price trials with unclear or hidden pricing"1
PayPal	"Subscriptions are built for merchants who need recurring billing with built-in trial periods"11	NoTrial rule in its Acceptable Use Policy8
Shopify	Shopify Subscriptions, "supported payment gateways" only; Stripe "Available only to select merchants"18	Stripe's and PayPal's lists apply in the US14
Square	Square Subscriptions, "no monthly fees or fixed costs"24	Doesn't support "(3) buyers or membership clubs" or "(6) direct marketing or subscription offers or services"21

Square doesn't define "direct marketing or subscription offers". Read it as aimed at continuity offers sold through marketing, not every recurring plan, and ask Square before you launch one. The card network rules for trials: free trials and negative option billing, and for recurring billing: subscription payment processing.

Which one fits which business

No single winner. Match the processor to what you sell and how you sell it, then add a second route.

Based on the policies quoted on this page, read November 3, 2026.

On Shopify, a third-party card provider takes over card payments: only one at a time, with a Shopify fee of 2% on Basic down to 0.2% on Plus19 20. Shopify Payments can stay on beside it for Shop Pay, local methods and failed-card recovery, at a 1.25% premium26. Details: high-risk payments for Shopify stores.

Running two processors is allowed when each knows what you sell through it. Splitting volume to stay under a monitoring threshold is not: Stripe lists "Evasion of card network chargeback monitoring programs" as a prohibited use1. How to do it within the rules: multiple merchant accounts. Tagada follows Visa and Mastercard rules and the laws that apply to payments.

Frequently asked questions

Which is better for high-risk businesses: Stripe, PayPal, Square or Shopify Payments?

None runs a high-risk program. Stripe has a published approval path for restricted businesses, PayPal a pre-approval list. Shopify Payments excludes six categories on top of Stripe's and PayPal's lists in the US, and Square excludes subscription offers sold through direct marketing. The best fit depends on your category and sales model.

Does Shopify Payments use Stripe?

In the US, yes, and PayPal too. Shopify's processor list names Stripe, Inc. and PayPal, Inc. for the United States, and its terms say each processor provides the prohibited and restricted categories. A product Stripe prohibits is off-limits on Shopify Payments even if your store itself is allowed.

How long can PayPal, Stripe or Square hold my money?

PayPal can hold a balance "for up to 180 days", sometimes longer under legal process. Stripe typically pauses payouts 120 days from its first email after a risk action. Square's terms set no length: it can defer payouts "temporarily or indefinitely". Shopify sets the terms in its notice.

Can I move my customers' saved cards if my account is closed?

From Stripe and Square, yes, to a PCI DSS Level 1 processor; subscriptions don't move. Braintree exports its vault to a PCI-compliant provider. We found no published procedure for Shopify Payments, and Shopify staff wrote in 2022 that it couldn't transfer payment details. Ask before you need it.

Can I use Stripe and PayPal at the same time?

Yes, if each processor knows what you sell through it. Many stores offer PayPal next to a card processor. What's not allowed is splitting volume to dodge monitoring programs, a prohibited use on Stripe. See multiple merchant accounts.
