Testimonials

Ignacio Doncel
Ignacio Doncelusa

Founder at WishYoo

We needed to enhance our UX by redesigning our platform to make it more engaging. Clockwise Software restructured the backend to ensure intuitive functionality and delivered an eye-popping design. They were professional, always available, and effective communicators, quickly learning our tools. The system passed stress tests with 5,000 users and showed no lag, exceeding our expectations.

Dan Weber
Dan Weberuk

President

I needed a larger development team to expand my company, and Clockwise Software has been instrumental in developing four mobile applications. They’ve provided QA testing, automated testing, and implementations using React, Redux, and Node.js. Two apps achieved 100% code and branch coverage, and another reached 99.4%. I’m very pleased with the quality of the work we’ve done together.

How we develop Next.js applications

These six steps shape the core of our Next.js development services.

1. Discovery: Plan all details from the start

This stage is all about efficiency and fewer risks. We define priorities, outline the scope, create detailed feature specs, and set up a roadmap that makes further development feel less like chaos and more like clockwork.

Plus, we scope every discovery work to match the complexity and needs of your app — no more, no less than enough to start building.

Learn more

2. Design: With business goals in mind

We believe that good design is one with functional clarity. We focus on creating experiences that make sense for your users and support what your product needs to achieve. Every screen is prepped for smooth dev handoff, with clear logic, sharp visuals, and documented flows.

Learn more

3. Development: Built for velocity and transparency

We run Next.js development in clear, focused sprints. Your Next.js app is in the hands of devs and project managers who’ve worked on dozens, so the process is structured, predictable, and agile — because we know that changes are part of the game. You stay connected through regular updates, demos, and easy access to progress tracking, so it’s clear where the project stands at all times.

4. Testing: The right tests and a continuous process

We don’t believe in one-size-fits-all testing. Instead, when providing Next.js development services, we pick only the tests that truly matter for your project, saving time and cutting noise. Testing happens every sprint, covering everything from unit tests to feature sets and full system flows. This way, bugs get caught early, and your app stays solid as it grows.

Learn more

5. Deployment: Coordinated releases to avoid disruptions

When it’s go-time, we don’t just hit “deploy” and hope for the best. We carefully coordinate the release with you, double-check every detail, and if it’s an upgrade or migration, we plan timing to avoid disrupting your users. Our goal is seamless updates that keep your app running flawlessly.

6. Growth: Ready for what’s next

When a project wraps, we make sure knowledge transfer is smooth and complete, so you’re never left in the dark if you decide to go solo.

And if you want to keep us around? We’re all in, ready to help your app evolve, improve, and adapt as your business grows

Clearing up your concerns

What types of Next.js projects do you typically handle?

We build a range of Next.js apps, from SaaS platforms, e-commerce sites, and marketplaces to PWAs. Our experience spans industries like logistics, entertainment, health, MarTech, and real estate, which helps us handle diverse requirements with confidence.

Can you connect a Next.js app to third-party services?

Yes. As a part of our Next.js development services, we frequently integrate payments (Stripe, PayPal), CRMs, authorization (OAuth, SSO), and more. We handle everything from SDK setup and secure API calls to error handling and version updates, ensuring integrations are stable and future-proof.

How do you ensure my Next.js app stays fast as it scales?

We use built-in Next.js features like server-side rendering, static generation, and smart caching to keep your app fast even as it grows.

Pages load quickly thanks to automatic code splitting and image optimization. This involves designing optimized data structures and structuring granular API endpoints to ensure the frontend fetches only the data it needs.

We also implement a robust backend caching layer, which, combined with efficient database queries and proper indexing, significantly reduces the database load.

How experienced are your Next.js developers?

We’ve had Next.js in our stack for 5+ years. The devs on your project won’t be learning it as they go — they’ve already built and supported production apps with it. Many are still on long-term Next.js projects, so their skills are sharp and current.

The average tenure in our Next.js development company is 3.8 years. We keep people around by offering growth, pay that matches their skills, and projects that challenge them. It’s how we keep expertise in-house — and on your side.

How will communication be handled during the Next.js development process?

We set up a communication plan before the project kicks off. Together, we agree on how we’ll talk: channels, meeting formats, update frequency, and who’s involved. That way, nothing gets lost, and you always know where the project stands without chasing anyone.

Will I have direct access to Next.js developers?

It depends on the cooperation setup. If you go with full-cycle development, your primary contact is a project manager who keeps everything organized and moving. But you’ll still be in the same Slack channel as the developers and can communicate with them.

If you go with a dedicated team or staff augmentation, then yes, you’ll talk to Next.js developers directly and manage their work day to day.

How do you ensure my Next.js application will be high-performing?

We write clean, modular components, use SSR and static generation to maintain performance, and test your app under real-life conditions. Post-launch, we use monitoring tools to keep the app fast as your user base grows.

Here’s how we typically optimize performance:

  • Rendering strategy: We use SSR, ISR, or static export based on what fits each feature best.
  • Code splitting: We split bundles to reduce the initial load and speed up navigation.
  • Efficient data fetching: We optimize API calls with SWR or React Query and keep the client lean.
  • Load testing: During QA, we simulate traffic spikes to catch bottlenecks early.
  • Performance testing: We test the frontend to catch inefficient rendering loops, memory leaks, and redundant network requests.

How scalable will my Next.js application be for future growth?

We’ll discuss your scalability needs at the start and build with them in mind. From code structure to infrastructure, we keep it modular, use scalable APIs, and rely on tools like Vercel or containerized environments for easy scaling. So when you grow — more users, more traffic, more features — the app keeps up without hitting a wall.

Do you provide ongoing support and maintenance after launching the Next.js app?

Yes, if you want to continue our partnership, we’re ready to help improve your Next.js app. Whether it’s fixing defects, updating features, or fine-tuning performance, our Next.js development services are here to help your product evolve and stay reliable after launch.

How quickly can your team respond to urgent support needs or fixes?

During working hours, we’re quick to jump in; most issues are picked up the same day. If you expect critical support outside of those hours, we agree on expectations upfront, so you’re not left guessing. Your app matters to us, and we make sure support is steady, transparent, and works for you.

How do you estimate costs for Next.js development services?

We start with a work breakdown structure: defining features and breaking them into tasks. Then, the tech lead and QA estimate the effort based on their experience with similar apps. We also assess risks early, factoring in what could impact timing or complexity so you get a realistic estimate.

What are typical timeframes for developing a Next js application?

A solid MVP usually takes 4 to 6 months, but the timeline depends on your app’s scope, tech complexity, and how much is defined upfront. If there’s existing code, third-party tools, or integration-heavy logic, we’ll account for that in the timeline. After MVP, we can continue with improvements, new features, or scaling.

How flexible are you in scaling the Next.js team up or down?

We’re ready to scale with you. Need to speed up? We can ramp up quickly with developers already experienced with Next.js. Need to scale down? We plan the shift so there’s no knowledge loss. We stay in sync with your priorities to adjust the team based on your current phase and goals.

What roles will be included in my Next.js project team?

It depends on what we’re handling. If we provide Next.js frontend development services, your team will typically include a Next.js developer (or a few), a development team lead, QA, a UI/UX designer (if a design is in scope), and a project manager.

For full-stack apps, we add backend developers, a business analyst to shape the logic, and DevOps to set up stable infrastructure.
