Marketplace development process

Here’s how we bring your product to life:

1. Discovery: Set the foundation

We start by deciding on the optimal tech approach to build a marketplace that matches your goals. From functionality breakdown to detailed product requirements, architectural design, and risk register, we consider every detail and confirm it with you. By the end, you’ll have a clear, actionable plan that shows exactly how we’ll bring your vision to life β€” without surprises.

2. Design: creating seamless user experiences

A great marketplace balances ease of use with a design that catches attention. We focus on user-friendly navigation, intuitive flows, and an attractive visual style that sets your marketplace apart. Before moving forward, we’ll share wireframes and an interactive prototype, giving you the opportunity to explore the design firsthand. Your feedback guides the final touches, ensuring everything looks and feels exactly as you envisioned. Whether it’s guiding users through complex workflows or adding elements that make your brand memorable, our goal is to deliver a design that works for your audience and business.

3. Development: Bring it to life

Our marketplace development services are based on transparency and expertise. Our developers bring 10 years of experience in building B2B, B2C, and C2C marketplaces to create your platform from the ground up. We set up a scalable infrastructure that can handle growing traffic, implement functionality and design in code, and integrate your marketplace with third-party tools, configuring APIs to work exactly as you need. By following PMI standards and agile practices, we keep your project on track and deliver everything on time and within budget, even if unexpected changes come up in the process.

4. Testing: Polish the platform

It’s time to make sure your marketplace matches your quality metrics across all areas: functionality, security, performance, and usability. We identify potential issues, check if features meet product requirements, and fix the found flaws before launch. For each project, we have a custom testing plan, so we do only what matters and brings value. It can be regular code checks for smaller projects or a full suite with automated tests, stress testing, and security audits for complex platforms. We approve the test plan with you at the start and follow it throughout the testing stage, ensuring no details are overlooked and no unnecessary steps are taken.

5. Deployment: Make your marketplace live

When your marketplace is ready, we focus on the product launch, which is a bit more than just hitting β€œgo.” From coordinating the timing to handling last-minute adjustments, we’re there with you at every step. After launch, our online marketplace development services don’t end. When you have feedback from early users, we’re quick to refine your platform, helping you align with the market demands and make sure the marketplace is ready for the long run.

6. Growth: Partner for the long run

Whenever you’re ready, we’ll be here to help you grow your business. Our team can take over refining features, adding new ones, enhancing user experience, or scaling the platform. If you’re ready to wrap up, we’ll ensure a smooth knowledge transition with all documentation in place. However, if long-term collaboration fits your plans, we’re here to grow alongside your product, providing the flexibility you need to meet your objectives.

Clearing up your concerns

Will the marketplace fit our business model and user needs?

Your needs and requirements are at the heart of our work. At the start, we analyze your goals, the preferences of end users, and any specific requirements you have for the platform. Based on this information, we define the functionality of your marketplace, how it will work, and what criteria it must meet. From authorization to integrations with payment systems, shipping providers, and other third-party tools, every element will support your business model and user needs.

Can we migrate from an existing platform to a custom one?

Yes, our online marketplace software development company can handle migration. During the discovery stage, we’ll analyze your current platform, data volumes and types, and necessary integrations. This preparation allows us to plan the migration process thoroughly, minimizing downtime and avoiding data loss. We’ll transfer your data, including user accounts, listings, and transactions, while ensuring that your business operations and user experience remain uninterrupted.

Can it handle more users as we grow?

Scalability is an essential requirement for every marketplace we develop. Cloud-based infrastructure, efficient database solutions, and architecture designed to handle increasing users and activity β€” all these ensure your marketplace can grow without slowing down. The system can easily adjust, scaling infrastructure resources to meet the demand.

Will it integrate with payment gateways/shipping services?

Whether you need payment gateways like Stripe and PayPal or shipping solutions like FedEx and UPS, we’ll have it covered. We assess your needs and the services you plan to use, diving into their APIs to ensure it’s possible to configure connections to your needs without problems. Our experience with dozens of tools means we can recommend reliable options if you’re unsure. By planning for integrations from the start, we make sure that your marketplace will work with integrations as you expect.

How do you keep user data secure?

We implement industry-standard security practices, such as data encryption, multi-factor authentication, and role-based access control, to safeguard sensitive information. For marketplaces, we also address specific risks like payment security, ensuring compliance with standards like PCI DSS, and managing access to personal data under regulations like GDPR. Security measures are planned, approved, and tested from the start, with ongoing assessments to keep your platform protected as it evolves.

Can it support multiple languages or currencies?

We can design marketplaces to support multiple languages and currencies from the start. This includes handling translations and ensuring proper formatting for dates, numbers, and addresses. For currencies, we can integrate payment gateways like Stripe that offer built-in multi-currency support, allowing users to pay in their preferred currency.

How will you optimize it for SEO?

We take care to make your marketplace easy for search engines to crawl and rank. For example, we optimize page load speed, make the platform mobile-friendly, and implement metadata.

Can you meet our quality standards?

We start aligning with your quality standards during the discovery phase, discussing all the criteria that matter to your business. Throughout development, we focus on continuous quality assurance with code reviews, regular feedback loops, and demos to ensure everything meets your requirements. Our agile approach allows us to adapt and refine the product in case your requirements change while maintaining high-quality delivery. Thanks to this structured process, we have a 99.89% acceptance rate of our work.

How do you keep us in control throughout the process?

You’ll have access to all project deliverables: documentation, design files, code repositories, kanban boards, and more. Our marketplace development services include frequent demos and sprint reviews, giving you the opportunity to review and approve work at every stage. On top of that, we establish clear communication channels and regular calls to discuss progress, timelines, and budget status. This ensures your feedback is always heard, decisions are made collaboratively, and any changes are discussed and approved upfront. Every step of the process is designed to keep you informed, involved, and in full control.

Do you help us retain expertise over the parts we outsource?

Our process includes maintaining detailed records of features, system requirements, a technical approach, and workflows, ensuring no knowledge is lost. Your team will have access to code repositories, detailed documentation, and all deliverables. Whether you want to maintain your marketplace in-house or switch to another marketplace development company, we’ll provide thorough knowledge transfer sessions so your team is fully equipped to take over the platform.

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

We have processes in place to ensure you get exactly what we agree upon. Every requirement, from features to designs, is documented and confirmed upfront. Throughout the project, we follow Agile practices, giving you access to the work in progress through demos, code repositories, and documentation. Regular updates ensure you see the marketplace development progress, allowing for adjustments early if needed. Our track record speaks for itself β€” 99.89% of our work meets client expectations.

Will the team be consistent so they understand our product?

Most of our engineers stay with us for years, with an average tenure of 3.8 years. This stability means the same experts who start your project are likely to see it through, building detailed knowledge of your goals and technical needs. If a key team member does leave, we have a thorough knowledge transfer process in place. All critical information is documented and shared with the team, ensuring no knowledge gaps. New team members are onboarded quickly and efficiently to maintain momentum and keep your project on track.

Can we take the outsourced code for internal maintenance?

We ensure complete transparency and control over the codebase. From day one, you’ll have access to the repository, detailed documentation, and all deliverables. Every pull request includes clear comments, and our code is written with readability in mind, following industry best practices. To further support internal maintenance, we document the architecture, workflows, and key integrations. If your team needs to take over, our marketplace development services include a structured knowledge transfer process with walkthroughs, Q&A sessions, and technical handovers. This ensures your in-house team fully understands the code and can manage the marketplace without problems.

Will language barriers affect communication?

98% of our clients are from the US and UK, and they consistently point out that our communication is clear and efficient. We focus on delivering messages in a way that’s easy to understand, whether it's about technical details or project updates. From the start, we establish a communication plan with clear roles, channels, and regular updates to keep everyone aligned. Whether it’s through text, calls, or demos, we ensure smooth communication throughout the entire project.

Will we retain full IP ownership of the product?

Yes, you will retain full IP ownership of your marketplace. From the outset, we ensure that all work we do on your project is exclusively yours. Our contracts clearly outline that you hold the rights to the code, design, and any other deliverables we create.

How do you endure stability, given the situation in Ukraine?

Our team is decentralized across multiple locations, both within and outside of Ukraine, allowing us to stay operational without any major disruptions. We have successfully scaled projects and signed long-term contracts, ensuring consistent headcount and delivery throughout the war period. Moreover, our energy independence minimizes any risk of downtime, enabling us to ensure our ability to deliver regardless of external circumstances. We’ve proven our ability to adapt quickly, keeping projects on track and maintaining business continuity even in uncertain times.

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

Our experience in marketplace development and project management approach helps us to establish predictable timelines and cost structures from the start. As we’ve built a similar functionality before, we can accurately estimate the time and resources needed for specific features. Throughout development, we closely track the Schedule Performance Index (SPI) and Cost Performance Index (CPI), which helps us measure how well the project is staying on schedule and within the planned budget. If any changes arise, we assess their impact on both timelines and budget, discuss them with you, and adjust as needed to stay on track. This approach helps us to achieve less than 10% CPI and SPI variance across our projects.
