We’ve spent over two decades developing high-scale B2B and B2C eCommerce and patent-processing solutions that include:
The scale of our products and the resulting need to integrate them with scores of diverse payment systems have given us an ultimate grasp of the payment gateway integration process.
Our developers are equally skilled in employing the Direct Post, Hosted Payment Gateway, and Integrated payment gateway integration methods and are always prepared to use the one that fits best. They are also conversant with using SDKs. Furthermore, our R&D team has come up with a proprietary payment gateway integration framework to expedite the integration and cut the payment gateway integration cost. Our proprietary integration and custom payment gateway development services cover pre-built connector modules for major gateways, standardised compliance validation checkpoints, and reusable settlement reconciliation components — cutting typical integration timelines by 20–30%.
We integrate all major payment gateways, PSPs, and acquirers — selecting and configuring them based on your geography, transaction volume, and compliance requirements.
Stripe, Square, PayPal, Amazon Pay, Worldpay
Our payment gateway integration services cover the full implementation lifecycle — from gateway selection and API development to compliance validation, testing, and post-launch maintenance. Every stage is engineered to keep payment transactions secure, fast, and scalable, tailored to your platform’s architecture and payment processing requirements.
For years, we’ve been heavily engaged in integrating our high-scale payment gateway solutions with payment systems and payment processors to support the ever growing business needs of our industry-leading eCommerce clients.
This has given us a high level of competence in developing succinct and secure payment APIs we use in our integrations. We also have experience with APIs from other software vendors. This includes REST API integration for modern gateways (Stripe, Adyen, PayPal), Webhook configuration for real-time event handling (payment confirmation, dispute notifications, refund triggers), and SDK integration for mobile payment flows (iOS/Android). As a certified Adyen Implementation Partner, our team has certified expertise in Adyen’s API across web, mobile, and POS channels.
Due to the breadth of our payment gateway integration efforts, our developers have acquired strong familiarity with, and experience in integrating an array of payment methods. More specifically, the major card networks, like Visa, MasterCard, and others, and digital wallets, like PayPal, Apple Pay, Google Pay, and others. Besides, we can also implement bank transfers, alternative payment methods, cryptocurrencies, and ACH payments.
We also integrate Buy Now Pay Later (BNPL) providers (Klarna, Afterpay) for retail clients, open banking payments (PSD2-compliant bank-to-bank) for EU markets, and local payment methods by geography — including iDEAL (Netherlands), BLIK (Poland), and local PSPs for the Philippines and UAE.
We are versed in developing payment gateway GUIs that are parts of user journeys and not additional barriers for our clients’ customers.
Despite the need to contain many details, our payment gateways are always designed to provide hassle-free UX and serve as a continuation of our clients’ marketing efforts. Checkout conversion rate is the business metric payment gateway UI directly affects. Our design approach addresses the three most common checkout drop-off triggers: unnecessary redirect steps, form field overload, and lack of trusted payment method options at the point of purchase. We build one-click payment flows for returning customers, PCI DSS-compliant inline card forms for brand-consistent checkout, and mobile-first layouts tested across iOS Safari, Android Chrome, and in-app WebView.
Security is a topmost priority we always pay utmost attention to. Our developers can skillfully implement the whole range of security means that are usually used to secure the payment gateway-related interactions, including TLS/SSL encryption, user authentication, tokenization, and fraud prevention.
Our security implementation covers: tokenization — replacing cardholder data with non-sensitive tokens so card numbers never touch your servers, directly reducing PCI DSS compliance scope; 3D Secure 2.0 (EMV 3DS) authentication for SCA compliance under PSD2; AI-powered fraud scoring via real-time anomaly detection on transaction patterns; P2PE (Point-to-Point Encryption) for in-person payment terminals. We have implemented each of these in production payment systems processing hundreds of millions in annual transaction volume.
SPD Technology’s payment gateway integration projects have delivered measurable outcomes — from reducing failed payment transactions and cutting integration timelines to processing $140M/month in GPV and supporting $1B+ in total transaction volume across 11 geographies.

SPD Technology brings three capabilities that most integration vendors cannot credibly claim together: certified Adyen partnership for enterprise-grade gateway implementations, a proprietary integration framework that reduces timelines by 20–30%, and production experience on platforms processing over $1 billion in annual transaction volume.
We develop feature-rich payment gateways for massive-scale eCommerce platforms and handle a raft of related integration. Correspondingly, our gateway integration experience spans a diverse range of payment systems and related challenges we’ve dealt with. To illustrate, we’ve integrated one of the high-scale marketplaces we’ve developed with 20+ payments systems that hail from an extensive range of geographies.
Our gateway integration experience spans Adyen (certified Adyen payment integration and implementation), Stripe, PayPal, Braintree, Worldpay, and 15+ additional payment systems across the US, Canada, UK, Denmark, Netherlands, Norway, Poland, Spain, Greece, Philippines, and UAE. For each geography, we have navigated the local compliance requirements, settlement file formats, and preferred payment methods.
We’ve delivered a long range demanding solutions to the compliance-intensive industries like eCommerce, Fintech, and Insurance. Each of these solutions had to be rendered compliant with the various applicable regulations. Our significant experience has given us an understanding of the optimal ways to ensure compliance with the PCI DSS, AML/KYC, and GDPR regulations.
In practice, PCI DSS compliance for payment gateway integration means designing the system architecture before writing code: defining CDE (Cardholder Data Environment) scope, choosing tokenization as a scope-reduction strategy, implementing network segmentation, and configuring audit logging for Requirement 10. We apply these decisions in discovery — retrofitting compliance after build is 3–5x more expensive.
A proven ability to implement safeguards against fraud, data theft, and data exposure is essential for ensuring payment transactions’ security. As a long-standing provider of Fintech software development services, we have strong familiarity with data encryption not only within the context of eCommerce or payment gateway integration. We are proficient in AI-powered fraud detection for payment systems, our experience of crafting sophisticated fraud prevention functionality for the Poynt Omnicommerce solution is an additional relevant asset we have.
Our fraud prevention implementations use neural networks and anomaly detection algorithms for real-time behavioral scoring — the same approach that secured the Poynt platform as it scaled to $140M/month in Gross Payment Volume. We build velocity checks, device fingerprinting, and card BIN intelligence into the transaction flow without adding latency that degrades checkout conversion rates.
Payment gateway integrations require ongoing maintenance as card network standards evolve (PCI DSS annual re-certification), new payment methods gain adoption (BNPL, A2A payments), and fraud patterns change.
After we integrate a payment gateway, our ongoing support model includes gateway version upgrades, settlement reconciliation monitoring, fraud model retraining, and compliance re-certification support. Clients including Poynt have maintained integration partnerships with SPD Technology for 5+ years.

Senior Engineering Manager eCommerce Solutions Company
SPD Technology’s work has been praised by the client for their consistency and high quality. Their communicative, responsive, and flexible project management ensures a positive collaboration. Ultimately, their professionalism and forward-thinking are impressive.
The dozens of payment gateway integrations we’ve achieved make us adept in tackling various integration challenges.
SPD Technology designs and develops complex payment gateways that support various payment scenarios. Our mastery with payment gateway architecture helps us in payment gateway integration too. Whenever we integrate a payment gateway into a website, it allows us to quickly find solutions to any architecture-related challenges we encounter.
Architecture challenges in payment gateway integration typically involve CDE boundary definition (which systems touch cardholder data), network segmentation between application and payment layers, and key management for encryption. Our architecture-first approach ensures these decisions are made before development begins, preventing the costly rework that retrofitted compliance requires.
We make a point of achieving the fastest possible transaction speed for each of our payment gateway integrations. For this purpose, we can employ different techniques and approaches, like optimizing the number of steps, employing payment batching and aggregation, or implementing payment caching and preauthorization. Our successful incorporation of ACH payments into a solution of one of our North-American clients has eliminated payment delays and resulted in a significant revenue increase.
We target sub-2-second end-to-end payment authorization for user-facing checkout flows, as transaction latency above 3 seconds correlates with measurable cart abandonment rate increases.
Ensuring compatibility in payment gateway integration is key. We solve any compatibility issues that may arise by carefully selecting a payment gateway that supports various devices and platforms or developing a payment tailored payment gateway, as well as by continuously conducting through compatibility testing.
Mobile compatibility is now the primary compatibility challenge: payment forms must work correctly in iOS Safari, Android Chrome, and in-app WebViews (e.g., Facebook In-App Browser), which each render and handle JavaScript differently. We test across all three environments before go-live.
It is essential for your payment gateway to provide scalability for supporting your future business expansion needs. We always design our payment gateway integration solutions with scalability in mind, making sure they allow for adding various new payment methods.
Our payment gateway integrations are designed for scale from day one. The BHN platform we integrated handles $1 billion in annual transaction volume across 210,000 merchants — requiring horizontal scaling, queue-based settlement processing, and circuit breakers for third-party PSP failures that could otherwise cascade into platform downtime.
Cross-border payment gateway integrations require navigating compliance layers that vary by geography: PCI DSS (global), PSD2 Strong Customer Authentication (EU/UK), GDPR data residency requirements (EU), state-level money transmission licensing (US), and local PSP regulations for each country.
We have managed compliance for payment integrations across 11 countries simultaneously, including the US, UK, Netherlands, Poland, Norway, Denmark, Spain, Greece, Philippines, and UAE.
Many payment gateway integrations go live with working transaction processing but broken settlement reconciliation — payments process correctly but funds do not settle accurately, creating financial exposure and triggering acquirer audits. We design settlement reconciliation into the integration architecture from the start: settlement file parsing for each PSP’s proprietary format, ledger reconciliation against your order management system, chargeback workflow integration, and real-time financial reporting dashboards. Our approach ensures reconciliation gaps are caught before go-live rather than discovered through financial discrepancies post-launch.
At scale, manual reconciliation is not viable. The BHN platform we integrated processes $1 billion in annual transaction volume across 210,000 merchants — requiring fully automated multi-PSP settlement processing, automated discrepancy flagging, and chargeback workflows that operate without manual review at every step.

The team at SPD Technology exceeds expectations. Their professional communication style makes them stand out, They’re a skilled group of detailed-oriented workers. Customers can expect a team that provides helpful suggestions to better their clients.
We’ve been engaged in integrating our globally used high-scale solutions with dozens of payment systems for numerous target audiences. These payment systems hail from different geographies that include the U.S, Canada, Denmark, the Netherlands, Poland, Greece, the U.K, Norway, Spain, the Philippines, and the UAE. Quite often, as a part of our services we’ve had to add some locally-preferred payment methods and deal with new related challenges. This has given our Fintech development team a solid wealth of payment gateway integration development experience we are keen to put at your disposal.
iDEAL and Klarna integrations for a market where iDEAL alone accounts for approximately 60% of all online payments.
Every business type carries its own payment architecture requirements, compliance obligations, and gateway preferences. SPD Technology’s integration experience spans eCommerce platforms, SaaS products, fintech systems, and global marketplaces, each delivered with the technical depth the use case demands.
High-volume eCommerce platforms require multi-PSP routing, one-click checkout for returning buyers, and compliance-aligned flows for gift card and voucher payments. Marketplaces add a layer of complexity — split payments to sellers, escrow holds, and per-merchant settlement routing that standard gateway integrations are not designed to handle out of the box. SPD Technology delivers payment software development for enterprise platforms at scale: the BHN platform aggregates 210,000+ merchants and processes $1B+ in annual transaction volume, while Poynt’s omnicommerce platform serves 30,000+ merchants across card-present and digital channels. Gateway experience includes Stripe, PayPal, Square, and Adyen, for whom SPD Technology holds an official Implementation Partnership, and our company excels at automated merchant onboarding and KYC for payment platforms.
Subscription billing and recurring payment systems introduce integration requirements that one-time payment flows do not: proration on plan changes, failed payment retry logic, dunning management, and idempotent API design to prevent double-charges on webhook retries. Settlement must also support automated invoice generation and revenue recognition aligned with your accounting infrastructure. SPD Technology integrates Braintree, Stripe Billing, and Adyen Subscriptions for SaaS platforms — covering the full subscription lifecycle from initial charge through cancellation and refund handling. Named gateway experience includes Braintree, Adyen, and Authorize.Net.
Fintech payment integrations operate under the strictest compliance requirements in the industry — PCI DSS, PSD2, AML/KYC verification at the point of payment, and OFAC screening for cross-border transactions. SPD Technology has built payment infrastructure for an FSA/HSA payments platform operating in a HIPAA-adjacent environment with 80%+ AI-driven accuracy, and an SMB funding platform that has disbursed $350M+ in financing. These environments require compliance to be designed into the payment architecture from day one, not retrofitted after go-live. Gateway and network experience includes Adyen, ACH networks, and open banking APIs.
Cross-border payment integration requires simultaneous support for 3D Secure authentication variants that differ by region (3DS1 vs 3DS2), multi-currency settlement pipelines, and locally preferred payment methods that vary significantly by market. Generic gateway configurations fail here — each geography carries its own regulatory requirements, preferred PSPs, and authentication standards. SPD Technology has integrated payment systems across 11 countries including the US, UK, EU markets, Philippines, and UAE, navigating local compliance frameworks and dominant payment methods in each. This includes iDEAL and Klarna in the Netherlands, BLIK in Poland, Vipps and MobilePay across Scandinavia, GCash and PayMaya in the Philippines, and PayBy under CBUAE regulation in the UAE.

We’ve been engaged in delivering Fintech software development and payment infrastructure to well-established US businesses for 20+ years. These projects include an enterprise-grade financial data platform, a one-click payment system, a real-time financing application, a financial CRM, a personal financial application, and other types of advanced Fintech solutions.
Due to this, we traditionally employ a large number of eminently qualified Fintech developers. Currently, our Fintech practice consists of 270+ IT experts.
Every payment gateway integration we deliver follows a structured five-step process, built around the technical, compliance, and operational realities of live payment environments, not generic software delivery frameworks.
Our experts begin with assessing the architecture of your platform, as well as geographic footprint, transaction volume targets, and compliance requirements. This allows one to choose the best gateway and integration method among Direct Post, API-direct, or hosted. The platforms that already have PSP relationships are evaluated on switching costs relative to integration optimization, long before the start of any development activities. As a result, you will get a gateway recommendation with cost-of-ownership modeling and PCI DSS scope assessment.
When the assessment is complete, we move on to crafting an integration layer that includes REST API integration with the gateway, webhook receivers for asynchronous payment events (authorization, capture, refund, dispute), and a tokenization vault architecture to reduce PCI DSS scope. As for the decisions around security architecture, we document every move regarding network segmentation, encryption key management, and CDE boundary definition.
Our experts cover every need of your specific markets by configuring and testing each payment method, including digital wallets (Apple Pay, Google Pay, PayPal), card networks (Visa, Mastercard, Amex, Discover), BNPL providers such as Klarna, and locally preferred payment methods for each geography. We don’t treat all of this like a single pass, but rather test each method independently for refund processing, decline handling and authorization flows.
We validate PCI DSS compliance scope, configure 3D Secure (3DS2) authentication for PSD2 SCA requirements where applicable, and conduct penetration testing against the payment integration layer. For enterprise clients, we support the full PCI DSS QSA assessment process, providing architecture diagrams, network diagrams, and evidence packages required for certification.
Our experts treat launch as a phased rollout, with real-time monitoring, controlled transaction volume, and anomaly alert mechanisms. Settlement reconciliation is validated against existing order management systems, and chargeback workflows are tested before full traffic is released. After the launch, we provide long-term maintenance engagement that includes gateway version updates, ongoing monitoring, and compliance re-certification support.

A payment gateway integration connects your website, mobile app, or platform to the financial institutions that authorize and process customer payments. When a customer submits card details, the gateway securely transmits the payment data to the acquiring bank or PSP, receives authorization, and returns the result to your checkout in real time. The integration can be implemented via three methods: hosted redirect (lowest PCI DSS scope), API-based direct integration (highest customization), or Direct Post (middle ground), with the right choice depending on your checkout UX requirements and compliance posture.
Typically, the integration of payment gateways goes through five stages:
The timeline for a full enterprise integration is typically 6–16 weeks, depending on the number of payment methods and geographies covered. SPD Technology’s process is documented in detail in our integration methodology above.
Yes, PayPal is a Payment Service Provider (PSP), meaning it processes payments on behalf of merchants without requiring them to maintain their own merchant account with an acquiring bank. Other major PSPs include Stripe, Adyen, Braintree (owned by PayPal), and Square. PSPs differ from direct acquirer integrations in that they aggregate merchant accounts under a master account, simplifying onboarding but typically offering less control over interchange rates, acquiring relationships, and fund settlement timelines than a direct acquiring setup.
The right gateway depends on your business context. For general eCommerce, Stripe and PayPal are the most widely used — Stripe for its developer-friendly API and global reach, PayPal for consumer trust and instant recognisability at checkout. For enterprise and high-volume platforms, Adyen and Braintree offer greater control over the acquiring relationship and lower per-transaction costs at scale — SPD Technology holds a certified Adyen Implementation Partnership. For US subscription businesses, Authorize.Net and Square are widely adopted, while European platforms often prioritise local payment methods over gateway brand — iDEAL in the Netherlands, BLIK in Poland, Vipps in Norway. SPD Technology integrates all of the above, selecting based on your specific geography, volume, and compliance requirements.
The final cost of integrating a payment gateway is based on three key factors:
A basic single-gateway integration for a standard eCommerce platform can typically be completed in 4–6 weeks. An enterprise multi-gateway, multi-geography integration with full compliance architecture typically runs 10–16 weeks. SPD Technology provides scoped cost estimates following a discovery session where gateway, payment method, and compliance requirements are mapped in full.
