Complex E-commerce Development Tips

Modern & Intuitive Design

A leading‑edge ecommerce solution starts with a catchy, customer‑oriented design. That is why, when working on a complex product, we pay special attention to interfaces, making them easy to navigate and appealing.

MVP Approach

To avoid unsuccessful and pricey development iterations, we recommend e‑commerce startups to begin with a cost-effective MVP approach. A minimum viable product is the simplest version of a digital solution with basic product features sufficient for launching and offering it to early users. With an MVP, not only do you quickly test the viability of your idea but also save huge resources.

Result-Driven Attitude

Complex ecommerce development is an exciting, yet challenging process that requires a lot of time and effort. Before plunging into it, you should evaluate your abilities and get ready for possible pitfalls. Remember that a slight change of plans is an inevitable part of the development process and keep pursuing your goals, no matter what.

Complex E-commerce Development Process We Build

  1. High-Level Consultation
    An industry-leading ecommerce product starts with a breakthrough idea. Still, since sometimes even unique projects may seem unappealing to users, we always conduct market analysis before proceeding to the implementation stage. Our business analysts scrutinize the competitors, evaluate their products, and define your target audience and possible monetization strategies. After getting a clear vision of a future product, we do all the calculations.

  2. Project Requirements Analysis
    At this step, your idea of an ecommerce solution turns into a detailed plan. The developers define whether it is possible to implement all the desired features, functions, integrations, and payment gateways. Also, they select third-party service providers and optimal subscription models, as well as estimate the product's capabilities in the long run.

  3. Design & Architecture
    After that, our teams pool their efforts around design and architecture elaboration in compliance with the predefined requirements. While the UI/UX specialists pick design concepts and wireframes that will make your ecommerce website stand out among the competitors and ensure a stellar, eye-catching user experience, our engineers decide on the architecture pattern.

  4. Ecommerce Solution Development
    As soon as all the concepts are ready, our development team rolls up the sleeves and gets down to the e-commerce product creation. To streamline the process and save your resources, we stick to the MVP approach and automate all the processes that allow for automation.

  5. Software Testing
    The testing stage is a crucial one, as early users or beta testers finally get to see the preliminary product version, while testing engineers analyze its quality and security. After testing the functionality and performance of the solution, our specialists document all the results in a detailed report.

  6. Product Deployment
    Once the bugs are fixed and security mechanisms are boosted, the developers roll out the software to a wide group of users. A bit later, they collect and analyze customer feedback to define further development strategies.

  7. After-Launch Maintenance
    To stay afloat and not fall victim to hackers, it's essential to keep the product compatible with the latest technology updates. That is why, after the software launch, our teams keep a close eye on the product components and ensure timely support.

This is an estimated project roadmap. The exact workflow may vary depending on your goals and requirements.
