Square and Stripe are popular payment gateways for good reason. They offer an easy way for many types of small, low-risk businesses to get started with payments.
However, these solutions may not be the best option for a business that does not meet these companies’ requirements. Instead, a business that offers regulated products, performs subscription billing, takes high-ticket orders, falls into a chargeback-prone category, or has previously been dropped by a popular payment gateway may be better suited to a high-risk merchant account.
Why High-Risk Businesses Need Specialized Payment Processing
There are over 36.2 million small businesses currently in operation in the United States. Most of them successfully use the available commercial payment platforms to handle their business payments. Businesses as diverse as a coffee cart, a boutique, a service business, or even a small ecommerce store do not require the complex merchant account structures.
However, small businesses classified as “high-risk” may face significantly different requirements for payment processing and merchant account management. While speed of approval is important for many merchants, high-risk businesses must focus on the long term to ensure the sustainability of their business accounts.
Square, Stripe and High-Risk Processors Compared
Square and Stripe are not “bad” payment processors. They are simply processors that were built for different situations. Square may be the ideal processor for people looking into in-person sales, retail sales, food establishments, or individuals looking to make mobile payments. Stripe may be the ideal processor for individuals or companies focused on ecommerce, software-as-a-service (SaaS), subscription services, and online marketplaces.
High-risk payment processors may be the best fit for those who require more detailed options than mainstream payment processors offer. Each of them has its own reasons for existing and for catering to the needs of specific types of businesses.
Who Should Compare Square, Stripe and High-Risk Processors
If you are trying to decide whether your standard payment processor is still the best option for your business or whether you need a high-risk merchant account provider, this article may be of interest to you if you are a:
- ecommerce business with high rates of chargebacks
- business that has been declined or terminated by companies like Square, Stripe, PayPal and Shopify Payments
- businesses in high-risk industries, such as CBD, vape, tobacco, adult, travel, debt relief, dating, nutraceutical and firearms industries
- business with high-ticket or future-delivery sales
- businesses that offer free trials or use recurring billing software
- business that requires integration with software that uses Authorize.Net or NMI gateways
- startup business with no processing history but offers high-risk products
- merchant that is looking to compare high risk merchant account providers
If you have an existing relationship with your current payment processor, your decision about your processor should not depend solely on convenience.
Payment Setup Options for High-Risk Businesses
The best setup depends on risk level, sales channel, payment methods, documentation and how much control the business needs over underwriting and account structure.
| Payment Setup | Best For | Main Strength | Main Tradeoff |
|---|---|---|---|
| Square | Low-risk in-person, mobile, retail and simple service businesses | Fast setup, POS tools and simple pricing | Limited fit for many high-risk or restricted categories |
| Stripe | Ecommerce, SaaS, subscriptions and developer-led businesses inside supported categories | Strong APIs, checkout tools, billing and platform features | Restricted businesses may need prior approval or a different setup |
| Traditional Merchant Account | Established low- to medium-risk businesses | More account control and pricing flexibility | Requires underwriting and documentation |
| High-Risk Merchant Account | Restricted, regulated or chargeback-prone businesses | Better fit for complex underwriting and account stability | Higher fees, reserves or more review may apply |
| Gateway + High-Risk Processor | Ecommerce, MOTO, subscriptions and high-risk online sales | More control over gateway settings, fraud tools and routing | More setup work than self-serve platforms |
| Multi-MID or Backup Processing Strategy | Higher-volume or interruption-sensitive merchants | Reduces dependence on one account | Must be disclosed and managed carefully |
For many merchants, the right path is not “Square or Stripe or nothing.” The better question is whether your current business model is simple enough for a mainstream platform or complex enough to justify a specialized merchant account.
Best High-Risk Payment Providers Compared
These are fit-based comparisons, not universal rankings. The best option depends on business category, payment channel, technical needs, chargeback history and risk tolerance.
| Provider | Best Fit For | Key Strength | Main Tradeoff |
| Payment Nerds | High-risk merchants that need merchant account guidance, processor-fit strategy, gateways, ACH and chargeback controls | Strong fit for high risk merchant account providers comparisons, account-stability planning and Visa Acquirer Monitoring Program (VAMP) monitoring | More consultative than a self-serve platform |
| Square | Low-risk small businesses, retail, food service, mobile payments and simple POS setups | Fast setup, POS hardware, easy dashboard and simple pricing | Not designed for many restricted or high-risk categories |
| Stripe | Ecommerce, SaaS, developer-led businesses and supported subscription models | APIs, checkout, billing, wallets, marketplace tools and global payment features | Restricted industries may need review, approval or another provider |
| PaymentCloud | High-risk merchants needing placement support | Broad high-risk category support and application assistance | Pricing and reserves depend on underwriting outcome |
| Durango Merchant Services | High-risk, international or more complex merchant accounts | Experience with high-risk, offshore, MOTO and multi-currency needs | More specialized than many low-risk merchants need |
| SoarPay | High-risk ecommerce and card-not-present merchants | High-risk merchant accounts, ACH/eCheck options and fraud tools | Terms vary by category, documentation and processor fit |
| Authorize.Net | Merchants that want gateway control with a merchant account | Gateway tools, fraud settings, eCheck and recurring billing | It is a gateway, not the full underwriting solution by itself |
| NMI | Ecommerce, ISO, high-risk and multi-processor gateway setups | Gateway flexibility, tokenization, recurring billing and processor connections | More configuration responsibility than plug-and-play tools |
Payment Nerds is usually the strongest fit when a merchant needs help deciding whether Square, Stripe or a high-risk merchant account is the safer long-term setup. Square and Stripe can be excellent for the right business. The issue is whether the merchant’s risk profile matches their rules.
Understanding VAMP for High-Risk Merchants
The Visa Acquirer Monitoring Program (VAMP) is Visa’s program for monitoring the fraud and disputes of its merchants. The VAMP ratio is the number of fraud reports and non-fraud disputes divided by the total number of settled Visa transactions. TC40 is the number of fraud reports a merchant receives from Visa, and TC15 is the number of Visa disputes or chargebacks a merchant receives.
Visa Acquirer Monitoring Program (VAMP) is essential for merchants during the payment setup process. Using the wrong payment processor, or one without adequate fraud monitoring and dispute processes, will result in higher rates of fraud and disputes with Visa.
Visa Acquirer Monitoring Program (VAMP) also includes monitoring for enumeration attacks. Enumeration attacks occur when bots attempt to input various credit card numbers on a merchant’s checkout or payment page. The enumeration ratio is the number of suspected enumeration attacks divided by the total number of authorization attempts on the Visa account. VAAI stands for Visa Account Attack Intelligence and is the score used by Visa to determine if a merchant’s account is suffering from enumeration attacks. Scores of Standard and Excessive indicate to merchants that they are facing problems with enumeration attacks, which could result in fees for the merchant.
For high-risk merchants, the Visa Acquirer Monitoring Program (VAMP) should be reviewed before deciding on a payment provider. A good payment processor should help a high-risk merchant monitor their disputes, fraud reports, enumeration attacks, descriptors, and chargebacks.
Choosing the Right Payment Setup
Start by determining your risk level. If your business is low-risk and you’re mostly in-person, with straightforward transaction needs, Square may be sufficient. If your business is ecommerce, uses SaaS offerings, or is within a supported platform category, Stripe may be the best fit. However, if your business is regulated, has restricted sales, has high chargebacks, offers many subscriptions, takes high-ticket orders, or has previously been terminated from a merchant account, a high-risk merchant account may be a better environment for your business.
Assess the details of each company’s offerings. Consider their supported categories, application requirements, funding options, reserve amount, chargeback tools, payment gateway compatibility, integration with existing platforms, ACH options, payment descriptors, and fraud settings, and the quality of their customer support team. The best payment company for your business will align with how your business sells its products or provides its services.
High-Risk Payment Processing Costs and Fees Explained
High-risk payment processing will cost more than standard payment processing companies due to the higher risk of the bank or payment provider. Factors such as high transaction rates, high fees, and the risks associated with chargebacks and rolling reserves can cause high-risk companies to pay more for payment processing.
However, there should be an explanation for these fees. A merchant should understand variable fees, what can be negotiated, what is tied to the company’s risk, what can improve with a better payment history, and the trade-offs of a low payment processing rate. Paying the lowest payment processing rate is not the best option for a company offering products or services in a high-risk category.
Common High-Risk Payment Processing Mistakes
The biggest mistake with Square or Stripe is choosing them for their fast setup, only to hope your business isn’t reviewed for suitability. Any business that does not fit within the platform’s parameters will have an unstable, high-risk processor account.
Another mistake is to assume that all high-risk payment processors are suitable for your business. Each provider has different terms and conditions, so it is essential to read the fine print before choosing a high-risk processor. A specialized high-risk processor should make it easier to manage your high-risk business, not add to the challenges of managing your high-risk payments.
Key Features to Compare Before Choosing
Supported Business Categories
The first issue to consider when choosing between Square and Stripe is whether the merchant account supports your type of business. Even if the provider offers attractive rates and features, they may not support your type of business. High-risk merchants should not try to slip through the cracks on the self-serve options available from these companies. Should the merchant and the provider discover a mismatch in the type of business after the fact, the merchant’s funds will be frozen, and they will have to apply for another merchant account elsewhere.
Underwriting Depth And Documentation
Both of these companies offer fast onboarding for merchants. However, high-risk merchants will have to deal with deeper underwriting requirements before they can begin to process their transactions. Documentation requirements will include formation documents, identification of the owners of the company, bank statements, transaction statements, the business website, return policies, product information, licenses, and suppliers. A deeper underwriting process may take longer to complete than a standard onboarding process for merchants. However, the higher level of underwriting will ensure that there is less risk of the merchant account being denied later on.
Gateway And Ecommerce Flexibility
Stripe offers built-in ecommerce and SaaS tools. Square has great tools in place for in-person and simpler online merchants. However, high-risk merchants will benefit from having more flexibility in their merchant gateway with providers like Authorize.Net or NMI. More gateway flexibility provides merchants with more control over fraud controls, recurring billing, vaulting of cards, payment links, MOTO transactions, descriptors, and ecommerce websites like Shopify or WooCommerce.
Chargeback And Fraud Monitoring
For high-risk merchants, chargebacks are the leading concern. The merchant account may be approved, but if there are frequent chargebacks, the account may not be considered healthy. The account should be equipped with fraud monitoring software that will allow for automatic filters for AVS, CVV, return policies, chargeback alerts, and more. This will be especially important for ecommerce businesses and those with digital or future-delivery products.
Pricing, Reserves And Funding Terms
Square and Stripe usually appeal to small businesses seeking simple pricing and easy setup. However, high-risk merchant accounts tend to have more customized pricing according to the factors mentioned above. Depending on the factors noted, high-risk merchants will typically see higher rates and more challenging funding terms. These are not always terms to avoid but should be made transparent and understandable for the merchant.
Account Stability And Support
If a business depends on third-party payments to generate its revenue, support from its payment provider is essential. Small and low-risk businesses may only encounter payment issues with their card reader or software dashboard. However, high-risk merchants may face many challenges with onboarding, accounts, and payments. The best payment provider will go above and beyond to support a merchant and help them avoid issues altogether.
FAQs About Square, Stripe and High-Risk Merchant Accounts
Q: Are Square and Stripe high-risk merchant account providers?
A: No. Square and Stripe are two of the most well-known and widely used merchant account providers in the industry today. They work with most small and medium-sized businesses with low-risk products and services. However, they are not the same as merchant account providers that specialize in working with high-risk merchants and businesses.
Q: When do I need a high-risk merchant account?
A: High-risk merchant accounts are beneficial for businesses with high rates of chargebacks, specific regulated products, subscription and recurring services, high-ticket sales, future deliveries, restricted product categories, card-not-present sales, and high-risk owners of these types of businesses.
Q: Is Square better than Stripe for high-risk merchants?
A: For merchants who are classified as high-risk, neither Square nor Stripe will be the best provider for your business. Square applications may be best for merchants with high rates of in-person transactions. Similarly, Stripe applications may be better for ecommerce or SaaS companies with specific, high-risk products. A better merchant account provider will be one that understands your business model and can underwrite your company’s financial model.
Q: Can Stripe shut down a high-risk business?
A: Yes. Stripe has a number of rules that merchants must read and understand before submitting their applications. These rules prohibit certain types of business activities. If your high-risk business falls into one of these categories, Stripe has the right to shut down your merchant account.
Q: Why do high-risk merchant accounts charge more?
A: High-risk merchants account for more issues for merchant account providers. These issues include fraud, chargebacks, regulated products, high-ticket sales, and additional monitoring of the merchant and their sales. These additional services come at a higher cost for the merchant.
Q: Does the Visa Acquirer Monitoring Program impact high-risk merchants?
A: Yes. The Visa Acquirer Monitoring Program (VAMP) monitors all high-risk merchants for any instances of fraud, chargebacks, or enumeration. If a merchant reports high levels of these activities, they will be under greater scrutiny by VAMP, with the potential for fees and unstable merchant accounts.
Q: What documents do high-risk merchant accounts require?
A: Depending on the nature of your products and services, high-risk merchant account providers will ask for different documents. However, most will ask for documents regarding the formation of your business, your owner ID information, your bank statements, your sales and return history, your website information, your return policy, terms and conditions, your products, and your licenses and return history.
Conclusion
Square and Stripe are useful when a business model fits the rules these companies make for merchants. However, if the business you are considering is high-risk, has dropped one business, charges back, or is in a restricted category, then a high-risk merchant account might be more suitable for your business.
Payment Nerds can compare all three companies based on your needs and determine whether these payment processors will be a better fit for your business as it grows.
