The right decision is less about what is technically possible and more about what the business needs to own, what it can afford to operate, and where payments fit into its long-term strategy.
Payment Infrastructure Is Not a Uniform Solution
Before deciding whether to integrate payment gateway or build more of the stack yourself, it helps to understand the four main approaches.
1. Integrate an existing payment gateway
One can link their account with payment providers like Stripe and Adyen. These payment providers handle a good part of the payment-related infrastructure. That allows them to direct their resources to other areas of their business, like their product and the customers.
2. Build a custom payment layer
This is the middle way. Create their own checkout experience, payment logic, routing, branding, and workflows, and still leverage an external processor for the underlying transaction infrastructure. This gives them more control, without having to build everything from the ground up.
3. Build own payment infrastructure
Building and operating more of the payment stack means they control payment flow and data, but raises the liability for security as well as compliance, reliability, and fraud.
At the same time they are gaining more control over data and payments and creating more opportunities for customization, they are also increasing the exposure to risk for a variety of things like security, compliance, reliability, and fraud.
4. Become a Payment Facilitator
A PayFac setup takes things a step further by making payments part of the overall business offering. Rather than using payments only for their own transactions, one can enable other businesses to accept and manage payments through their platform.
This may generate an additional revenue stream, but it also increases the regulatory and operational burdens. There are choices along a continuum. The real decision is not just about building or integrating a payment system. It is about deciding which parts of the payment setup make sense for the business to handle in-house.
Why This Is More Important in 2026
Payment expectations, compliance requirements and operating economics are constantly changing, making the decision all the more critical. As businesses expand across payment methods, markets, and providers, managing those moving parts becomes a technology decision in its own right. Instead of building every payment capability internally, many businesses are looking for ways to bring providers, routing rules, payment methods, and transaction workflows together without taking ownership of the entire underlying infrastructure.
That is where payment orchestration becomes particularly relevant. The platform segment is expected to account for 57.0% of the global payment orchestration platform market share in 2026, showing the significance of flexible payment infrastructure for businesses managing online transactions at scale. Payment orchestration brings a broader range of applications, including E-Commerce, Travel and Hospitality, Retail, BFSI, Healthcare, Media and Entertainment, and SaaS and Subscription Businesses, making businesses to connect different payment requirements without rebuilding their entire payment stack each time they expand.
PCI DSS requirements are increasingly difficult to ignore
PCI DSS v4.0.1 is the current standard as of 2024. As of March 31, 2025, certain payment security and compliance requirements changed to become future-dated.
This is important for businesses considering building a payment infrastructure in-house, because compliance isn’t something they check off the list once before launch. Operating the system now includes security controls, verification, oversight, documentation, and continuous risk management.
The Payment Experience Is Now Part of the Product
Customers are increasingly expecting payments to be a natural part of the product, not a separate process. SaaS platforms, marketplaces, financial applications and other digital products often require payments embedded right into their workflows.
That becomes even more important when a business operates across different payment methods, currencies, and markets. An off-the-shelf checkout can work well at the beginning, but as payment requirements become more complex, businesses may need greater control over routing, checkout logic, provider selection, and transaction flows. A custom payment layer can provide that flexibility without requiring the company to build the entire payment infrastructure itself.
The need is particularly visible in digital commerce. The E-Commerce segment is estimated to capture 26.0% of the global payment orchestration platform market share in 2026, highlighting the importance of flexible payment infrastructure for businesses managing online transactions at scale. Payment orchestration supports a broader range of applications, including E-Commerce, Travel and Hospitality, Retail, BFSI, Healthcare, Media and Entertainment, and SaaS and Subscription Businesses, allowing businesses to connect different payment requirements without rebuilding their entire payment stack each time they expand.
Build vs. Integrate: The Core Trade-Off

It is much simple to scale up once they adopt payment gateway instead of having their own payment infrastructure. Building gives better control over how payments work, but that control comes with additional responsibilities.
There is also a middle ground. A company can integrate an external processor while developing its own payment orchestration, checkout, routing, reconciliation, or payment experience. That approach can provide meaningful control without requiring the business to become responsible for every underlying payment function. For businesses that need this middle ground, Bacancy Technology’s fintech integration services can connect payment providers to existing product, ledger, reconciliation, KYC, and analytics workflows while keeping transaction processing with established providers.
How to Decide Which Payment Approach Fits the Business
The choice is not as simple as deciding between building and integrating. Use the Build vs Integrate Payment Gateway decision to evaluate their business against five factors.
1. How much are you processing?
Begin with the existing transaction volume, followed by consideration of what they expect the transaction volume to be in the coming years.
Increased transaction volume may affect processing costs and might warrant an examination of higher ownership of payments. However, it should be considered together with payment method, location, transaction amount, provider costs, and fraud.
No specific transaction threshold makes building the obvious choice.
2. How important are payments to the business?
Look at the role payments play in their overall revenue and how much they matter to the business.
If they have a SaaS product, payments could simply be one of the features needed to charge the customers. If they have a marketplace, payments can be a crucial part of the model as the platform takes payments from their customers and disperses them to the sellers.
The more integrated payments are to the business model, the greater the need for control over them.
3. How complex are the compliance requirements?
The regulatory landscape may play a big role in the economics of construction.
Think about the markets that is served, the payment solutions that they offer, KYC/AML needs, PCI DSS needs, their licensing needs, data protection laws, as well as what is entailed in managing customer funds.
If they lack the resources for compliance and risk management in their firm, additional payment capabilities will add up to more work than they expect.
4. What expertise does the existing team bring?
Payment infrastructure development involves more than just software developers. Application Security, Payments Operations, Fraud Prevention, Compliance, Finance, Reconciliation, Infrastructure, and Incident Response are among other skills that are required.
However, if all these skills already reside within the organization, then extending payment ownership will not be too difficult compared to what smaller organizations can do.
5. What level of responsibility is the team prepared to handle?
Greater control also means greater accountability. Before building, ask whether the organization is prepared to own payment failures, security incidents, fraud controls, compliance requirements, reconciliation issues, disputes, system availability, and ongoing maintenance.
If the answer is no, integrating with an established provider may be more appropriate.
The Additional Costs to Build a Payment Gateway
The initial development budget is only part of the calculation. One of the biggest mistakes businesses make is treating payment infrastructure as a project that ends when the system goes live.
Ongoing PCI compliance
Payment security requirements continue after implementation. The organization may need ongoing validation, testing, monitoring, documentation, and remediation.
Fraud management
Fraud patterns change constantly. Rules that work today may become ineffective as fraudsters change their behavior. An in-house system therefore requires continuous monitoring, rule tuning, testing, and potentially additional fraud technology.
Reconciliation and financial operations
A payment system needs to connect transactions with the rest of the business. Orders, captures, refunds, chargebacks, fees, payouts, and settlements all need to be reconciled correctly. A payment can succeed technically while still creating financial problems if the surrounding systems don't match.
Security and maintenance
Infrastructure requires ongoing patching, monitoring, incident response, vulnerability management, testing, and upgrades. These costs continue whether transaction volumes are increasing or not.
Opportunity cost
There is also the cost that doesn't appear on a payment infrastructure budget. Every engineering hour spent maintaining payment systems is an hour that cannot be spent on their core product. For an early-stage company, that opportunity cost can be significant.
Which Situations Suit Each Approach?
The right approach becomes easier to understand when they look at practical scenarios.
Early-stage SaaS company: Integrate
A startup that needs to start collecting subscription payments generally doesn't need to build a payment gateway.The acquisition of an existing provider would facilitate quicker deployment for the firm, relieve infrastructure pressures, and enable its engineers to work on the product.
Marketplace: Consider the PayFac model
A marketplace has its unique needs due to the relationship between payments and the platform’s business model. It might require seller onboarding, payout processing, refund processing, and transaction fee processing. Based on the size and structure of the platform, becoming a PayFac or leveraging an existing payment service provider for marketplaces is something to consider.
Enterprise or financial institution: Evaluate greater ownership
A bank or large enterprise operating under unique regulatory, routing, settlement, or payment requirements may have stronger reasons to control more of its payment infrastructure. Customization and control in such cases can have much strategic importance.
Even here, the integration approach may be flexible enough to provide the needed capabilities without necessarily building every function within the payments infrastructure. This is particularly relevant as the U.S. payment orchestration platform market continues to develop alongside increasingly complex digital payment requirements, giving larger organizations more options for connecting providers, managing transaction flows, and supporting different payment methods while retaining control over critical payment operations.
The key question is not whether an enterprise can own more of the stack, but whether that additional ownership delivers enough operational value to justify the compliance, security, maintenance, and infrastructure responsibilities that come with it.
The Decision Doesn't Have to Be Permanent
The "Build vs Integrate" Payment Gateway decision is not final. One can begin with an integrated approach, then add a custom payment layer as needs grow, and at a later stage consider taking control of more infrastructure as transaction volume increases.
The payment orchestration ecosystem itself reflects this range of approaches, with established providers and technology companies including Stripe, PayPal, Adyen, Checkout.com, CellPoint Digital, BR-DGE, Spreedly, IXOPAY, Primer, BlueSnap, APEXX Global, Gr4vy, Akurateco, Payoneer, and Worldpay serving different parts of the payments infrastructure and orchestration landscape.
For businesses that need additional technical expertise during this transition, Bacancy Technology can help them hire fintech developers to support payment integrations, custom payment workflows, and related financial product development.
