What's Stopping Progress in Higher Education?
Register now
Choosing an online payment gateway used to feel like a narrow technical decision. In 2026 it is a strategic one. Organisations of every kind, from ecommerce shops and SaaS businesses to universities and business schools, now need far more than basic card processing. They need to accept the payment methods their customers and students actually use, settle and reconcile money reliably, meet security and regulatory obligations, and give internal teams clear visibility over what has been paid and what has not.
Expectations differ sharply by country. A buyer in Germany may reach for a bank transfer or a local method, a customer in China may expect a digital wallet, and an applicant in Brazil may want to pay by instalments. Finance teams care about settlement timing, payout reporting and matching transactions to invoices or student records. IT and security teams care about integrations, data handling and compliance. Regulated sectors need governance and auditability. And higher education has a particular requirement that generic ecommerce does not: payments need to connect to applications, admissions, enrolment and the student record.
The important thing to accept up front is that the best payment gateway is not the same for every organisation. Headline transaction fees matter, but they are only one input. Geography, payment methods, customer experience, fraud controls, reconciliation, integrations and sector fit all shape the right choice.
This article is a practical comparison of ten leading online payment gateways and payment solutions for 2026. It explains what a payment gateway does, how gateways differ from processors and payment service providers, what to evaluate, and where each provider fits best. It also looks closely at higher education, because for universities and specialist institutions the strongest setup is one where the gateway is connected to the wider student lifecycle rather than sitting off to one side.
An online payment gateway is technology that securely captures and transmits payment information between a customer, a merchant, a payment processor, an acquiring bank and the relevant card network or payment method provider.
In plain terms, it is the layer that authorises an online payment and moves the sensitive data safely so that funds can be collected. A modern gateway can support debit and credit cards, digital wallets, bank transfers and local payment methods, depending on the provider and the market.
A few points are worth clarifying, because terminology varies:
Several distinct roles sit behind a single online payment. Understanding them makes vendor comparisons much easier, because many modern providers now combine two or more of these roles in one product.
| Role | What it does |
|---|---|
| Payment gateway | Securely captures and transmits payment details, and passes the transaction on for authorisation. Think of it as the entry point for the payment. |
| Payment processor | Routes the transaction between the acquiring bank, the card networks and the issuing bank, and handles the mechanics of moving money. |
| Merchant account | A type of bank account that lets a business accept and hold card payments before funds are settled to its main bank account. |
| Acquirer (acquiring bank) | The bank or financial institution that accepts card payments on the merchant's behalf and settles the funds. |
| Payment service provider (PSP) | Combines gateway, processing and often a shared merchant account into a single service, so a business can start accepting payments quickly. |
| Payment orchestration | A layer that routes transactions across multiple gateways, processors and methods to improve acceptance rates, resilience and reporting. |
| Payment platform | A broader commercial term for a provider that offers many of the above capabilities together, frequently with fraud, billing and analytics. |
The key takeaway is that the tidy definitions rarely map one-to-one onto real products. Stripe, Adyen, PayPal, Checkout.com and others each blend gateway, processing and PSP functions. When comparing providers, the useful question is not "is this a gateway or a processor?" but "which of these roles does this product cover, and which do we still need to source elsewhere?"
Transaction fees are important, but they are only one part of the evaluation. Below is a practical framework covering the criteria that most often determine whether a payment solution succeeds in production.
A useful discipline is to weight these criteria before you look at any pricing page. The cheapest headline rate is a poor guide if the provider cannot support your markets, your reconciliation needs or your compliance obligations.
| Provider | Best suited to | Strengths | Watch-outs | Higher education relevance |
|---|---|---|---|---|
| Stripe | Online-first businesses, SaaS, marketplaces | Developer experience, broad methods, billing, hosted and embedded checkout | Can be complex for non-technical teams; availability and add-ons vary | Application fees, deposits and payments where integrated into an admissions platform |
| Adyen | Enterprise and multi-market organisations | Single platform, global acquiring, local methods, risk tools | Oriented to larger, complex operations | Large or international institutions needing global infrastructure |
| PayPal / Braintree | Businesses wanting PayPal wallet plus card processing | Consumer familiarity, PayPal wallet, broad integrations | Risk reviews/reserves, regional differences, fee complexity | A familiar option for applicants, parents and sponsors |
| Worldpay (part of Global Payments) | Established organisations needing enterprise processing | Scale, global acquiring, omni-channel | Contract and pricing complexity; integration under new ownership | Large institutions with existing finance and payment infrastructure |
| Checkout.com | Digital businesses, fintech, marketplaces | Modular platform, acquiring, fraud and data focus | Enterprise and digital-first orientation | Institutions or edtech platforms with complex international needs |
| Square | Small businesses, in-person plus online | Ease of use, POS, invoices, payment links | Less suited to complex international tuition workflows | Smaller providers, events and short courses |
| Authorize.net | Organisations wanting gateway plus merchant-account flexibility | Long-established gateway, recurring billing, fraud tools | Older model; more configuration and merchant decisions | Institutions with existing merchant relationships |
| Cybersource | Enterprise payment and fraud management | Visa-owned infrastructure, fraud decisioning, global scale | Enterprise complexity and implementation effort | Larger institutions needing enterprise-grade risk tooling |
| Mollie | European businesses | Simple setup, European methods, subscriptions, links | Best fit inside supported European regions | European providers, short courses and local payment preferences |
| Flywire | International and education payments | Local-currency payer experience, reconciliation, education focus | Not a general-purpose gateway for every ecommerce case | Strong for international tuition, deposits and student payments |
The sections below expand on each provider. Where specific fees are mentioned, they are drawn from official pricing pages and can change, so always confirm current pricing directly with the provider.
Best suited to: online-first businesses, SaaS, marketplaces, digital products and teams that value strong APIs.
Stripe has become a default choice for developers building online payments. Its strengths are breadth and quality: a large set of payment methods, robust subscription and billing tools, fraud tooling, and both hosted and embedded checkout options. Stripe advertises a pay-as-you-go model with no setup or monthly fees for standard processing, and support for over 100 payment methods on its pricing page.
On cost, Stripe's published card rates differ by country. In the United States the standard online rate is 2.9% plus 30 cents per successful card charge, while in the United Kingdom the standard rate for domestic cards is 1.5% plus 20p, according to Stripe's UK pricing. International cards and currency conversion carry additional charges, so the effective rate for cross-border payments is higher than the domestic headline. Premium products such as advanced fraud tooling and recurring billing add further cost.
Watch-outs: the flexibility that developers love can be a burden for non-technical teams, account availability varies by country, and add-ons can make the true cost harder to predict than the headline rate suggests.
Higher education relevance: Stripe is well suited to application fees, deposits and other payments where it is integrated into an admissions or enrolment platform, giving admissions and finance teams a clean flow rather than a disconnected payment page. Full Fabric supports direct integration with Stripe for exactly this purpose.
Best suited to: enterprise, global commerce and organisations with complex, multi-market payment operations.
Adyen is built around a single platform that combines gateway, processing and acquiring, with strong support for local payment methods and enterprise-grade risk management and reporting. For organisations operating across many countries, consolidating on one provider can simplify operations and improve visibility.
Watch-outs: Adyen is designed for scale, and its model can be more than a smaller organisation needs. Implementation typically assumes dedicated technical and commercial resources.
Higher education relevance: large institutions or international education groups that need global payment infrastructure and unified reporting across markets.
Best suited to: organisations that want PayPal wallet acceptance alongside conventional card processing, which Braintree (owned by PayPal) provides.
The core appeal here is consumer familiarity. Many payers already have a PayPal account and trust the checkout, which can help conversion for one-off payments. Braintree extends this with card processing and broad ecommerce integrations, and in some markets additional wallets such as Venmo are available.
Watch-outs: Risk reviews, reserves and account limitations can be part of PayPal's operating model, so organisations should review the relevant terms, dispute processes and support model before relying on it for critical payment flows. Regional differences in features, and a fee structure that can become complex once cross-border and currency conversion charges apply, are also worth noting, and the checkout experience involves trade-offs depending on how it is implemented.
Higher education relevance: a familiar payer option for applicants, parents and sponsors, especially where PayPal is already widely used. Full Fabric supports direct integration with PayPal for application, tuition and deposit fees where configured.
Best suited to: established organisations needing enterprise payment processing and global acquiring.
Worldpay is one of the largest names in payment processing, with scale across cards, ecommerce and point of sale. An important 2026 development is ownership: Global Payments completed its acquisition of Worldpay on 9 January 2026, combining the two businesses. According to Global Payments, the combined company serves more than six million merchant locations and processes roughly $3.7 trillion in payment volume and around 94 billion transactions annually across more than 175 countries.
Watch-outs: enterprise payment relationships often involve contracts and pricing structures that are less transparent than pay-as-you-go providers, and organisations should factor in how the Worldpay and Global Payments product roadmaps and support models evolve following the acquisition.
Higher education relevance: larger institutions with existing enterprise finance and payment infrastructure, particularly those already working with Worldpay or Global Payments.
Best suited to: digital businesses, marketplaces, fintechs and organisations needing flexible global payment infrastructure.
Checkout.com offers a modular payments platform spanning acquiring, gateway, fraud tools and analytics, with a strong emphasis on performance data and international coverage. It appeals to organisations that want granular control over acceptance rates and payment routing.
Watch-outs: the platform is oriented towards enterprise and digital-first businesses, and may offer more capability and complexity than a smaller organisation requires.
Higher education relevance: institutions or education technology platforms with complex international payment needs and the resources to implement and manage a flexible payments stack.
Best suited to: small businesses, organisations selling both in person and online, events, and teams that want simple setup.
Square (part of Block) is known for ease of use. It combines point-of-sale hardware, online payments, invoices and payment links, with quick onboarding and a predictable interface. For straightforward payment collection, it removes much of the friction associated with traditional merchant accounts.
Watch-outs: Square is less suited to complex international tuition or enterprise payment workflows, and its geographic availability is narrower than the global enterprise providers.
Higher education relevance: smaller education providers, events, open days, short courses and simple fee collection rather than international tuition operations.
Best suited to: organisations that want a long-established payment gateway with flexibility over their merchant account.
Authorize.net (a Visa service) is a mature gateway with recurring billing, fraud tools and a broad ecosystem of merchant service providers. It suits organisations that already have, or want to choose, their own merchant account and value a well-understood, stable gateway.
Watch-outs: the interface and setup model feel older than newer platforms, and getting started can involve more configuration and more decisions about merchant accounts and add-ons.
Higher education relevance: institutions with existing merchant accounts or finance relationships that want to keep their acquiring separate from the gateway.
Best suited to: enterprise payment management, fraud decisioning and global organisations.
Cybersource, also owned by Visa, provides payment acceptance combined with enterprise-grade fraud management and risk tooling at global scale. It is aimed at organisations that treat fraud and payment operations as a serious, data-driven discipline.
Watch-outs: as an enterprise platform, it involves implementation effort and complexity that smaller teams may find disproportionate.
Higher education relevance: larger institutions or groups that need enterprise risk management and payment acceptance infrastructure across multiple markets.
Best suited to: European businesses and organisations that need popular local European payment methods.
Mollie is a European payment service provider valued for straightforward setup and support for the local methods that matter across European markets, alongside subscriptions, payment links and common ecommerce integrations. For organisations focused on Europe, it can be simpler to adopt than the global enterprise providers.
Watch-outs: Mollie is a strong fit within its supported European regions and less relevant for organisations whose payments are concentrated elsewhere.
Higher education relevance: European education providers collecting application fees, short-course payments and deposits, where local payment preferences drive conversion.
Best suited to: education, international payments, and other sectors where the cross-border payer experience matters, including healthcare and travel.
Flywire is a specialist rather than a general-purpose gateway, and that is precisely its strength for education. It focuses on the international payer experience, letting students and families pay in their local currency and preferred method while the institution settles in its own currency, with automated reconciliation. According to Flywire, its network supports more than 140 currencies and over 1,200 local payment methods across more than 240 countries and territories, and it works with a large number of education institutions and recruitment agents worldwide. Flywire also states that it holds a seat on the PCI Security Standards Council Board of Advisors and integrates with major student information systems.
Watch-outs: Flywire is not the tool for every generic ecommerce use case. Its value is concentrated in cross-border, high-value and sector-specific payments rather than, say, high-volume low-value retail.
Higher education relevance: especially strong for international tuition, deposits and student payments. Full Fabric offers a native Flywire integration, which is covered in more detail below.
Higher education has payment requirements that differ meaningfully from generic ecommerce. A university is not processing a single checkout; it is collecting different payments at different stages of a relationship that can last years.
Typical requirements include:
A gateway processes the payment, but institutions also need operational context around it. Consider the questions that admissions and finance teams ask every day:
If payments sit in a separate finance or payment tool with weak integration, admissions and finance lose visibility, reconciliation becomes manual, and students experience more friction at exactly the point where they are deciding whether to commit. This gap between processing a payment and understanding a payment in context is where a purpose-built higher education platform such as Full Fabric fits.
To be clear, Full Fabric is not a payment gateway. It does not compete with Stripe, Adyen, PayPal, Worldpay or Checkout.com to process card transactions.
Full Fabric is a purpose-built higher education platform that connects CRM, admissions, applications, enrolment, payments, student records and reporting around one connected learner record. Its role in payments is to link the transaction to the person and the workflow, so that a payment is not just money received but a meaningful event in the student lifecycle.
In practice, Full Fabric supports online payments as part of that lifecycle:
On providers, Full Fabric's help documentation states that it supports direct integration with PayPal, Stripe and Flywire, which can be used to charge application fees, tuition fees and deposits depending on configuration. Its native Flywire integration is designed so that students can complete payments without leaving the admissions platform, with automated reconciliation back to the record. As described in the Full Fabric and Flywire case study, the aim is to remove external portals and manual matching so that admissions, finance and recruitment teams work from the same real-time information. That case study also cites Flywire research suggesting that trust in the payment step is a genuine concern for students, with fewer than half feeling fully confident making online payments to universities, which is one reason a connected, in-context payment experience matters.
The strategic point is simple. The gateway handles the payment transaction. Full Fabric connects that payment to the applicant or student record and to the wider admissions and enrolment workflow, so teams can act on it. You can see how these payment connections sit alongside other systems on the Full Fabric integrations page.
It is worth being transparent about the boundaries:
For teams evaluating this, the relevant Full Fabric areas include enrollment management software, the admissions CRM, the student information system and the resources built for admissions teams. Institutions with particular structures, such as business schools and public universities, often have distinct payment and reconciliation needs worth mapping early. Governance questions can be reviewed on the security and GDPR page, and Full Fabric's contextual AI capabilities sit across the same connected record.
No single provider is best for everyone. The list below matches common situations to the providers best suited to them, using "best suited to" rather than "the best" deliberately.
Use this checklist during evaluation. The answers usually matter more than the headline rate.
A note on compliance: PCI DSS is not optional and it is not static. The current active version of the standard is PCI DSS v4.0.1, and for assessments conducted in 2026 all of its requirements are in scope, as confirmed by the PCI Security Standards Council. Choosing a provider that reduces your compliance scope, for example through hosted checkout and tokenisation, does not remove your responsibilities entirely; it changes them. Treat compliance as a shared, ongoing obligation rather than something a gateway handles on your behalf.
The best online payment gateway or solution depends on geography, payment methods, customer experience, risk, reconciliation, integration and sector needs. For most organisations, the right question is not "which gateway is cheapest?" but "which payment solution fits our operating model?"
For higher education specifically, the strongest payment setup is one where the gateway is connected to admissions, enrolment, finance and the student record, so that a payment confirms an offer, releases a place or updates an account without manual work. For universities, business schools and specialist institutions evaluating how online payments can fit into the wider student lifecycle, Full Fabric connects supported payment providers with CRM, admissions, enrolment, student records and reporting, helping teams treat payments as part of the learner journey rather than a disconnected transaction.
An online payment gateway is technology that securely captures and transmits payment information between a customer, a merchant, a payment processor, an acquiring bank and the relevant card network or payment method provider. It authorises online payments and can support cards, wallets, bank transfers and local methods.
A gateway is the entry point that captures and transmits payment details, while a processor routes the transaction between the acquiring bank, card networks and issuing bank to move the money. Many modern providers combine both roles, along with a merchant account, in a single service.
There is no single best gateway for everyone. Stripe is a common choice for developer-led online businesses, Adyen and Checkout.com for enterprise global commerce, PayPal for wallet acceptance, and Flywire for international education payments. The right choice depends on your markets, payment methods, integrations and sector.
It depends on the type of payment. Adyen and Checkout.com are strong for enterprise cross-border commerce, while Flywire is specifically built around the international payer experience with local-currency payment and reconciliation, which makes it a strong fit for tuition and deposits.
Higher education is best served by a gateway that connects to the student lifecycle rather than sitting separately. Flywire is a strong specialist for international student payments, and Stripe and PayPal are widely used for application fees and deposits. The greatest value comes when the chosen provider is integrated into an admissions and enrolment platform such as Full Fabric, so payments link to the applicant or student record.
At a minimum, major debit and credit cards and the leading digital wallets. Depending on your markets, you may also need bank transfers, open banking or account-to-account payments, and specific local methods. For international audiences, local-currency payment options can significantly affect completion.
It is fundamental. Any organisation that handles payment card data must comply with PCI DSS, currently version 4.0.1, with all requirements in scope for 2026 assessments according to the PCI Security Standards Council. Using hosted checkout and tokenisation can reduce your scope, but it does not remove your obligations entirely.
Most gateways let you issue refunds through a dashboard or API, and provide tools to respond to chargebacks (disputes) raised by cardholders. Costs and processes vary: some providers do not return the original processing fee on a refund, and many charge a fee per dispute regardless of the outcome, so check the details before committing.
Yes. Many providers support application fees, deposits and tuition, and some, such as Flywire, are built specifically for education payments including instalment plans. For institutions, the important factor is whether these payments reconcile automatically against the student record and connect to admissions and finance workflows.
Full Fabric is not a payment gateway. It is a higher education platform that connects payments to admissions, enrolment and the student record. Its help documentation states that it supports direct integration with PayPal, Stripe and Flywire for application fees, tuition and deposits depending on configuration, and it offers a native Flywire integration so students can pay without leaving the platform, with automated reconciliation for admissions and finance teams.
