Testimonials

Heiko Roth
Heiko Rothusa

COO of Agilea Solutions, CEO at Workerbee

Clockwise Software has been helping us create a digital marketplace for web and mobile platforms from scratch. They have been able to plan a great project with a limited budget. They’ve adhered to that plan, making us trust their work in every sprint that we start with them. They are valued members of our team, and we don't see that changing.

Iman Fadaei
Iman Fadaeiuk

Founder & CEO

We needed help to make our marketplace into a product, available as a service to people. Clockwise built the technology from a single marketplace into a multi-level marketplace solution. They've done exactly what we asked, delivering with technical skill, professionalism, and timeliness. Their team is clear, organized, and always available, accommodating our needs.

Ecommerce app development process

Here’s how we bring your product to life:

Discovery: Scope it smart

We kick ecommerce app development services off by aligning your goals with the right tech and product strategy. Together, we define your product vision and explore the best approach for your model, whether it’s D2C, B2B, marketplace, or subscription-based. We map out core features, flag potential risks, and identify what’s worth building first, so you can move fast without wasting time on the wrong things. You’ll get a clear scope, budget estimate, architecture plan, and a roadmap both teams can confidently follow.

Learn more

Design: Clarity is the strategy

We design ecommerce interfaces that feel easy from the first tap to checkout. Clear navigation, smooth flows, no clutter, just a layout that helps users do what they came for. You’ll get wireframes and an interactive prototype early on, so you can click around, leave comments, and steer things in the right direction. From there, we tweak visuals, polish the details, and make sure it all looks like your brand, not just another template.

Learn more

Development: Code that doesn’t crumble

Now we get to work. Our team writes clean, reliable code that turns plans into something real: a web app, a mobile app, or both, depending on what makes sense for your product. What we build works under load, connects with your tools, and holds up when things get busy.

You’ll get regular demos, see what’s done, and call out anything that needs a tweak. We work in sprints, stay flexible, and keep custom ecommerce app development moving without drama. Priorities shifted? No problem. We adjust fast and keep the roadmap solid. Your ecommerce app is ready to launch, easy to update, and solid enough to grow with confidence.

Testing: Every click should behave

We test what needs testing, no more, no less. Together, we set quality goals early on during ecommerce app development, then build a testing plan around them. For simple ecommerce apps, that might mean regular code checks and basic flows. For complex platforms, it’s a full setup: automated tests, performance checks, security audits, and stress testing.

Whatever the scope, the goal’s the same: to catch issues before your users do. We follow the plan, keep you in the loop, and make sure the product runs smooth, safe, and ready to go live.

Learn more

Deployment: Fully backed launch

Going live isn’t just pushing a button. During ecommerce app development, we help plan the timing, handle last-minute tweaks, and keep an eye on every moving part. When the product’s out in the wild, we don’t vanish. You’ll get early feedback, and we’ll help make sense of it: fixing what needs fixing, improving what could be better, and making sure your app keeps up with your users.

Whether it’s a soft launch or a big release, we stay close so nothing slips through the cracks.

Growth: Keep improving

Some teams finish and move on. Others keep building. We’re good with both. If you’re done with our ecommerce application development services, we’ll hand over clean docs, transfer knowledge, and make sure your team can take it from here.

If you’re staying in the game, we’re ready to help, refining features, shipping new ones, improving UX, or scaling your platform. Whether it’s adjusting based on user feedback or prepping for a growth stage, we stay flexible and focused on what actually moves the needle.

No-surprise ecommerce app development

Deadlines that hold

Estimates that hold

Clarity by default

Risks flagged early

Timeline in check

Timelines only work when they’re real. We use the Schedule Performance Index (SPI) and clear milestones to keep ecommerce app development moving without guesswork. If something changes (a new feature, a shift in scope), we’ll talk it through and show what that means for delivery. You stay in control with updates you can trust and a timeline that doesn’t keep slipping.

Clearing up your concerns

Can you migrate us from an existing platform to a custom one?

If you're switching from an off-the-shelf ecommerce solution to a custom app, we’ve got you covered. During the discovery phase, we’ll dive into your current system, mapping out your data, integrations, and technical constraints. This helps us plan a smooth, low-risk migration. Our ecommerce application development company will handle the transfer of product listings, customer accounts, order history, and more.

Will the platform handle increased traffic and sales volume as our business grows?

In ecommerce app development, we use a modular architecture and cloud infrastructure that make it easy to scale when your traffic or sales spike. The app is built with microservices, so we can add new features or scale specific parts of the system without touching everything else. We also run stress tests during development to catch weak points early, so your platform stays fast and stable as you grow.

How do you ensure the security of sensitive user and payment data?

We take security seriously and build it into the product from the start of ecommerce application development. For payments, we integrate with trusted providers like Stripe or PayPal; they handle PCI compliance, encryption, and fraud prevention at scale.

On our side, we secure all communication with HTTPS and TLS, apply tokenization where it’s needed, and build clean, auditable payment flows that are easy to test and monitor. We also control access with role-based permissions and follow data protection standards like GDPR.

How will you optimize it for SEO?

We build ecommerce apps with SEO in mind from the beginning. That means fast-loading pages, well-structured content, and technical features like clean URLs and schema integration. Whether it’s a product catalog or a blog section, we make sure search engines (and users) can find you easily.

Can it support multiple languages or currencies?

If you need it, we’ll build it in from the start. We design ecommerce apps with multi-language support, including proper handling of translations, number and date formats, and region-specific address inputs.

For currencies, we integrate with payment providers like Stripe that offer built-in multi-currency support, so users can pay in what’s familiar to them. Everything is planned early, so there’s no retrofitting later.

Can you meet our quality standards?

We define quality expectations together during the discovery phase, so there’s no mismatch later. From there, we keep quality consistent with regular code reviews, structured QA, and sprint demos where you can check every aspect of ecommerce app development yourself.

We follow real delivery standards (including PMI when it fits) and work with engineers who write clean code, build solid architecture, and don’t cut corners. You’ll see it all: commits, test coverage, pull requests, and progress in plain view. That’s how we keep our acceptance rate at 99.89% and how we’ve earned trust from teams that expect high standards.

How do you ensure we’re always up to speed?

You stay in the loop the whole way. We agree on a communication plan for your ecommerce app development project upfront. Weekly calls, async updates, access to boards, whatever works best for your team. You’ll have full access to everything: docs, designs, code, scope tracking, and status reports.

Every sprint ends with a demo. You see what’s done, give feedback, and nothing moves forward without your approval. If something changes, we show the impact; not just in hours, but how it affects the timeline and budget. You’ll always know what’s next and what it means.

How do you help us avoid knowledge gaps after outsourcing?

We make sure your team has full access to everything: code, docs, workflows, tickets, and the reasoning behind key decisions. With our ecommerce app development services, nothing is buried or held back.

You’ll be able to follow progress in real time, and when the time comes, we’re ready to hand things over properly. We walk your team through the system, explain how it all fits together, and answer every question. Whether you want to take over completely or keep us around in a support role, your team won’t be left guessing.

How do we know we’ll get exactly what we signed off on?

We start ecommerce app development by locking in the scope. Every feature, screen, and edge case is documented and confirmed before development begins. You review specs, wireframes, and prototypes early, so we’re aligned before anyone writes code.

Throughout the build, you’ll see progress in regular demos and shared boards. If something needs to shift, we flag it fast and show what it changes. We don’t overpromise or change the goalposts, we build what we agree on and keep you in the loop.

Will we have a stable team or frequent changes?

Our average engineer tenure is 3.8 years, and in 2023, we kept churn at just 5.5%. That means the people who start your project are likely to stick with it, building real product knowledge and long-term context.

You’re not working with a rotating cast. You’re getting a stable team of ecommerce app developers that knows your codebase, your goals, and how everything fits together. And if someone does transition, we handle it right: with clear documentation, structured onboarding, and zero disruption to your workflow.

Will we be able to maintain the code internally after delivery?

You’ll have full access to the codebase, documentation, and project history from day one of ecommerce application development. We write clean, readable code with clear structure and naming, so your internal team can step in without untangling a mess.

We also document the architecture, key workflows, and integrations, and if you're planning to bring things in-house, we’ll guide your devs through it, with walkthroughs, handover calls, and time for questions. 

Will we run into any issues due to language barriers?

Not at all. 98% of our projects are with clients in the US and UK, and clear communication is part of how we work. Whether we’re discussing business goals or technical edge cases, you’ll get straight answers and updates that make sense, with no confusion.

We handle async chats, docs, and real-time calls smoothly, and if anything’s unclear, we ask, not guess. Communication should never slow ecommerce app development down, and with us, it won’t.

Will we retain full IP ownership of the product?

You’ll own everything we create for your ecommerce application development project. That includes the code, designs, architecture, and documentation. Our contract makes it clear that you hold full IP ownership, so you can use, modify, or transfer the product however you choose. You paid for the work, it’s yours to keep.

How do you maintain operational stability in Ukraine?

We’ve structured our operations to stay stable no matter what. Our team is distributed across secure regions both inside and outside Ukraine, and we’re fully energy-independent, so blackouts or infrastructure issues don’t disrupt delivery.

Since the war began, we’ve kept projects moving, scaled teams, and signed long-term contracts with clients who trust us to deliver. With ecommerce application development, you get a consistent team, strong communication, and real continuity, even when the world throws curveballs.

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

We don’t guess, we estimate based on real experience with ecommerce development services. That helps us set realistic timelines and budgets from day one. Throughout the project, we track CPI and SPI to catch scope creep or delays before they turn into problems.

You get weekly reports that show where things stand. And if something needs to change, we flag the impact upfront, so you can make informed calls without losing control of the budget.
