Payment gateway integration services

Yes, we’ve done this before. For example, on the EmailMeForm project, we built modular integrations for both PayPal and Braintree without disrupting the existing codebase. We apply the same approach to any payment gateway integration service project: flexible architecture that allows you to support multiple gateways without adding technical debt.

We follow industry best practices to keep your transactions secure. Our team integrates your product with trusted payment providers like Stripe, PayPal, or Braintree — they handle PCI compliance and data protection. 

On our side, we ensure safe communication through HTTPS and TLS, apply tokenization to protect sensitive data, and build modular, auditable payment flows that simplify security checks. We also thoroughly test payment scenarios, covering error handling and fraud prevention, so your users get a secure and reliable payment experience.

Yes, and we prove it in practice. Our work has a 99.89% acceptance rate across projects. For payment integration services, we define quality benchmarks with you at the start and make sure they are fully met through functional, load, and security testing, along with strict compliance checks. Throughout the process, you’ll get clear, regular updates on progress and results.

You’ll have full visibility throughout the integration process. We share regular updates, detailed reports, and give you access to the codebase. Our workflow is built around transparency: sprint demos, clear documentation, and direct communication with the team. If you need answers or adjustments, you’ll always be able to reach the right people quickly.

We make sure your team fully understands how the integration works. We document the integration logic, API structure, workflows, and dependencies in detail. If needed, we also run knowledge transfer sessions and provide training. You get full access to the code and documentation, so your team can easily take over and evolve the system when needed.

We commit to clear agreements and deliver on them — backed by a 99.89% acceptance rate. Throughout the project, we track progress against agreed goals and monitor CPI/SPI to keep delivery on time and within budget. You’ll get regular, detailed updates, so you can see exactly how things are moving forward.

Yes — our average team member stays with us for 3.8 years, so we can keep the same specialists on your project for as long as needed. If changes do happen, we manage transitions carefully: with structured onboarding, detailed documentation, and proper knowledge transfer, while your project keeps moving without disruption.

We make sure your team can confidently maintain the system. You’ll get clear documentation, well-commented code, and a structured handover process. We also run knowledge-sharing sessions and training when needed, so your team is ready to handle future updates and troubleshoot without relying on us.

No. Our team works in English daily — 98% of our clients are from the US and UK and report smooth communication, both on project updates and technical details. You can expect clear, consistent conversations throughout the payment gateway integration process.

Yes — all intellectual property created during the project is yours. We provide full documentation and hand over the entire codebase once the work is done, so you have complete control over the product and everything built for it.

We’ve delivered stable, uninterrupted service throughout the war. Our team works from multiple locations in Ukraine and abroad, supported by a fully cloud-based setup. We have backup infrastructure to manage power or connectivity issues, and we plan proactively to keep projects running smoothly. You can count on us to adapt quickly and keep your online payment gateway integration moving forward.

We rely on hands-on experience to make realistic estimates — this helps prevent delays and budget overruns. As the project moves forward, we monitor progress closely using CPI and SPI metrics. If any changes come up, we manage them through a structured process and keep you fully informed, so the work stays aligned with your scope, timeline, and budget.
