What are Different Types of Payment Gateways?

In the ever-changing world of online payments, companies heavily depend on payment gateways for safe transaction processing and a smooth customer experience at checkout. PayFirmly has invested time and effort for several years in the integration, testing, and optimization of different gateways in the various sectors, including eCommerce startups to worldwide corporations.

It is very important to have a good grasp of the different payment gateway models, as each has a different use—some prioritize speed and simplicity, while others offer flexibility and compliance. Whether your project is a marketplace, subscription platform, or high-risk business setting, knowing the workings of each gateway can lead you to the most efficient, cost-effective, and scalable payment solution.

Payment Gateway vs. Payment Processor vs. Payment Orchestration

Before choosing any payment setup, it’s important to understand the three main components that work behind every online transaction — gateway, processor, and orchestration layer. While they might sound similar, each plays a very different role in how money actually moves.

• Payment Gateway: Acts as the bridge between your website or app and the payment processor. It securely collects customer card or wallet details, encrypts them, and transfers data for authorization.
• Payment Processor: Works directly with banks and card networks to approve or decline the transaction. It’s the technical engine that executes the payment initiated through the gateway.
• Payment Orchestration Platform: A more advanced layer — like what PayFirmly offers — that connects multiple gateways, processors, and payment methods under one intelligent system. It automatically routes transactions to the most successful or cost-efficient channel, improving approval rates and reducing fees.

Choosing between these depends on your business maturity. Startups may begin with a single gateway, while scaling enterprises often move toward payment orchestration for flexibility, performance, and global reach.

Types of Payment Gateways for Business

When businesses start scaling, choosing the right type of payment gateway becomes a strategic decision that impacts customer experience, approval rates, and operational flexibility. At PayFirmly, we’ve worked with all major models — from simple hosted gateways to fully customized API integrations — and have seen how each performs across industries.

Here are the main types of payment gateways and where they fit best:

Each type serves a different business stage and operational goal.

For instance, an adult entertainment site might prefer API-integrated gateways with multi-processor routing, while an eCommerce brand may rely on a hosted or self-hosted setup for simplicity and UX control.  At PayFirmly, we help companies combine these gateway types inside one orchestration layer, so they never get locked into a single provider.

Payment Gateways by Industry Focus

Not all payment gateways serve the same type of business. Over the years, at PayFirmly, we’ve seen how industry-specific gateways can make or break transaction success rates and compliance. Different sectors have unique risk levels, regulations, and processing needs, which is why selecting the right category matters more than most businesses realize.

• Adult Payment Gateways: Designed for high-risk businesses, these gateways specialize in age verification, compliance with legal frameworks, and support for adult-friendly payment processors like CCBill or Segpay.
• Casino and gaming gateways: Specifically designed for instantaneous fund transfers, they are equipped with fraud management systems, anti-money laundering procedures, and regional compliance assistance for online gaming platforms.
• eCommerce Gateways: They are tailored solutions that support various online payment methods through the shopping cart, handle multiple currencies, offer billing options that recur, and have connections with platforms such as Shopify, WooCommerce, and Magento.

In fact, every category has its own set of criteria for approval, time for settlement, and policies regarding chargeback. PayFirmly assists enterprises in all three sectors: Adult, Casino, and eCommerce, in the process of integrating compliant processors and, at the same time, keeping high approval rates with minimal chargebacks.

Pros and Cons of Each Payment Gateway Type

Each payment gateway model has its own advantages and trade-offs. The right choice depends on how much control, customization, and compliance your business requires. At PayFirmly, we always help clients balance speed, scalability, and security while selecting their ideal setup.

Hosted Payment Gateways

• Pros: Fast to deploy, minimal compliance responsibilities, and backed by globally trusted processors.
• Cons: Redirects can interrupt checkout flow, reduce brand control, and may impact conversion rates.

Self-Hosted Payment Gateways

• Pros: Provides seamless checkout within your domain, higher customer trust, and improved branding opportunities.
• Cons: Demands PCI DSS compliance, secure data handling, and consistent technical maintenance.

API-Integrated Payment Gateways

• Pros: Most suitable for operating via automation, subscription billing, and multi-currency transactions. Provides total control over the user interface and routing. 
• Cons: Needs developer skills, API security layers, and regular system audits.

Local Bank Gateways

• Pros: Makes local payments easier, frequently with low transaction fees and domestic settlements. 
• Cons: Only applicable to regional users and currencies; not fit for global expansion.

Payment Orchestration allows us at PayFirmly to bring together the best things from different sides all at the same time. It lets the companies link multiple gateway types at once, which results in the optimization of approval rates, lowering transaction costs, and providing uninterrupted payment continuity.

How Different Payment Gateways Perform in Real Business Scenarios

We’ve integrated and optimized nearly every kind of payment gateway — from hosted setups to complex API-driven architectures. The truth is, no single gateway fits every business. The right choice depends on your technical readiness, transaction volume, compliance level, and the customer journey you want to deliver. Here’s how each gateway type performs across real business factors that matter most:

Integration & Setup

Hosted gateways are quickest to launch with simple plugins or redirects, perfect for startups needing fast deployment. Self-hosted gateways demand technical setup and offer complete brand control. API-integrated gateways provide full customization for SaaS or marketplaces, while local bank gateways vary by each bank’s tech and region.

Pricing & Fees

Hosted gateways have predictable per-transaction fees and low setup costs. Self-hosted models need higher investment for security and compliance. API-integrated gateways can cut processing costs by up to 30% through smart routing with PayFirmly, while local bank gateways remain affordable but region-limited.

Transaction Speed

Redirects with hosted gateways may cause a minor delay in payments but they are still dependable. Self-hosted solutions rely on the optimization of the server. The fastest real-time approvals are provided by API-integrated gateways; meanwhile, the speed of local bank gateways is dictated by bank processing times.

Security & Compliance

Gateway hosting takes care of all the PCI DSS and encryption requirements. With self-hosting setups, you have to take care of the whole compliance. APIs can take off some of the security responsibilities, while local bank gateways will provide a secure environment for domestic transactions, but will have differences in the standards set for the global ones.

Customer Experience

Hosted gateways are trusted but may disrupt checkout flow. Self-hosted ones provide seamless on-site payments. API-integrated gateways give a consistent omnichannel experience, while local bank gateways earn user trust but offer limited design flexibility.

How to Choose the Right Payment Gateway for Your Business

Selecting the right gateway starts with knowing your business model and transaction behavior.

• If you’re launching fast, choose hosted gateways for simplicity.
• If you value brand consistency and own checkout control, go with self-hosted.
• For automation, scalability, and cross-border flexibility, API-integrated setups win.
• For domestic payments with strong local trust, local bank gateways remain solid.

And if you operate across multiple verticals — say, adult entertainment, casino, and eCommerce — you don’t need to choose just one. With PayFirmly’s orchestration platform, you can connect multiple gateways, route transactions based on risk or geography, and stay compliant under one unified dashboard.

Conclusion

Choosing the right payment gateway is more than a technical decision — it’s a long-term strategy that impacts conversions, cash flow, and customer trust. Whether you’re running an eCommerce store, a casino platform, or an adult entertainment site, every business model demands a different balance of speed, compliance, and control. Hosted gateways bring simplicity, API-integrated gateways bring customization, and orchestration platforms — like PayFirmly — bring everything together into one intelligent, flexible system.
