Software integration process

With 10+ years of experience and 100+ API integrations with global systems, we ensure seamless, secure, and scalable connections. Here’s how we do it:

1. Discovery & requirements analysis

We kick off a project by getting a clear picture of your systems and needs. We analyze API documentation, infrastructure, and specifics like rate limits, auth rules, or legacy system constraints. With this information, we can map out dependencies and define an optimal integration strategy to meet your needs.

Learn more

2. API architecture & security planning

When providing software integration services, we design future-proof API architecture that can handle high loads while staying secure. From OAuth and JWT authentication to data encryption (TLS 1.2+), rate limiting, and compliance (like GDPR), we cover security at every level. Whether you need banking-grade security or healthcare compliance, we build robust protections into your integration from day one.

3. Development & customization

Whether the plan is adapting existing APIs, building new ones, or bridging the gaps between them, this step is where we bring it to life. We fine-tune API calls for speed and efficiency, choosing REST or WebSockets based on what works best. If it’s an MVP, and your priority is speed, we leave optimizations for later iterations, focusing on delivering a functional solution first. Every integration is documented for maintainability, making future updates easy. If changes arise, it’s possible to adapt fast without breaking things.

4. Testing & performance optimization

We test integrations under real-world conditions to ensure they meet your requirements. If there’s a bottleneck, we find a way to remove it. If response times lag, we optimize. The goal is a stable, reliable integration that won’t cause problems for your operations.

5. Deployment & monitoring

We plan deployment to minimize downtime and risks. Together with you, we agree on the best rollout time to avoid business disruptions. After launch, we monitor API traffic, response times, and error rates in real-time. If something goes off track, we fix it before it affects your operations.

6. Ongoing support & scaling

Whether it's adjusting for new API versions, expanding functionality, or troubleshooting an unexpected issue, we’re here to help. If traffic spikes, we make sure the integration can handle it. If your stack changes, we adapt. All in all, we can help you make your integrations grow with you.

Clearing up your concerns

Will API integration disrupt our existing systems?

We carefully plan and test every integration to ensure it works smoothly with your existing setup. Before the rollout, we conduct impact assessments, check dependencies, and test in a controlled environment to prevent disruptions. The go-live happens at a time we agree on together, minimizing risks and ensuring business continuity. With phased rollouts and real-time monitoring, everything stays on track.

How do you ensure API security and compliance?

We follow industry standards like OAuth, JWT, and end-to-end encryption to protect data in transit and at rest. Role-based access controls ensure the right people have the right permissions, while compliance checks align with GDPR or, if you need, with other regulations. Along with regular security audits, automated threat detection, and penetration testing, all these measures help keep your integrations secure.

Will you match our quality standards?

We discuss quality standards with you at the start and outline requirements for integration as well as a testing strategy. When providing software integration services, we follow industry best practices, have refined QA processes, and strict acceptance criteria to meet your quality expectations. Our track record speaks for itself: we have a 99.89% acceptance rate of our work.

How do you keep us in the loop throughout the process?

You’ll always know what’s happening. We set up a tailored communication plan at the start: preferred channels, update frequency, and key touchpoints. You get full access to project status, documentation, and deliverables in real time. Regular demos, budget reports, and structured progress tracking help to create transparent collaboration.

How do we stay in control of the outsourced work?

Our software integration services always include a structured knowledge transfer. You’ll get clear documentation, code, and detailed reports on decisions and implementations. Your team has full access to repositories, technical specs, and process insights. Plus, we provide onboarding support and Q&A sessions so your in-house team stays informed and ready to manage everything long-term.

How can we be sure you’ll deliver exactly what’s agreed on?

We lock in requirements upfront, keep scope changes transparent (and always approve them with you first), and validate progress with frequent reports and demos. Plus, we have refined QA processes, CPI/SPI tracking, and clear communication in place, so the project is always under control, as well as the quality of integration. With this approach, our software integration company has a 99.89% work acceptance rate across our projects.

Will we have a stable team that understands our system?

Yes. Our average employee tenure is 3.8 years, ensuring long-term stability. If a key team member ever leaves, we’ve got it covered: critical knowledge is documented, transitions are seamless, and new members are fully briefed to avoid disruption. Your project stays in capable hands, no matter what.

How will we fully understand the outsourced code internally?

We keep everything transparent: your developers will have access to code and documentation. When it’s time to transition, we ensure a structured handover, working alongside your team to transfer knowledge, document every detail, and provide support. You’ll have everything needed to maintain and evolve the system independently.

Will language barriers affect communication?

98% of our clients are from the US and UK, and they’re completely comfortable with how we communicate both project updates and technical details. We focus on making sure you understand every detail. If anything needs clarification, we're always ready to explain in a way that makes sense to you, ensuring efficient collaboration without any misunderstandings.

Will we retain full IP ownership of the product?

Yes, 100%. You own everything: code, architecture, documentation. We don’t lock you in with proprietary tech or hidden dependencies. Once the project is done, you have full control over the integration, and we ensure a clean handover with all necessary knowledge transfer. It’s your product; we just help build it.

Can you guarantee stability given the situation in Ukraine?

Our team is distributed across multiple locations, both in and outside of Ukraine, ensuring uninterrupted delivery. We’ve built an energy-independent infrastructure to minimize downtime risks. Since 2022, we’ve maintained full business continuity, scaled projects without disruption, and secured long-term contracts.

How do you keep estimates accurate and our budget on track?

We base estimates on our experience with similar projects. Before development starts, we explore your requirements to create a realistic scope, timeline, and budget. Throughout the project, we track SPI and CPI metrics (we keep their variance under 10% on our projects) and provide regular budget reports so delivery stays predictable.

What if the third-party API changes after integration?

APIs evolve, but that doesn’t mean your system has to break. We design integrations with flexibility in mind, using versioning, error handling, and fallback mechanisms to prevent disruptions. If an API update requires adjustments, we assess the impact, adapt the integration, and test before deployment. Plus, as a part of our software integration services, we can set up monitoring to catch API changes early—so your workflows stay intact.

How long does software integration take?

Timelines vary based on complexity, system compatibility, and required customizations. Simple integrations can take a few weeks, while more advanced, multi-system setups may take months. We break the process into clear phases, provide realistic estimates at the start, and track progress closely so you always know where your project stands and when to expect delivery.

Can the integration be adjusted to new business needs?

Yes. We design software integration solutions with scalability in mind so they handle increased data loads, new features, and additional system connections. Whether you expand operations, add new tools, or need higher performance, we build flexible architectures that grow with you, preventing costly rebuilds. Plus, we optimize API performance to keep integrations efficient as demand rises.
