Custom online store development

Let’s go from idea to launch together

eCommerce website design process

01. Diving into your business and market research

To achieve your business goal, our team studies your niche deeply. Based on the data obtained, we figure out what solutions will work, bring profit, and improve your position on the market compared to competitors.

02. Writing specs and making a prototype

Requirements specification and prototype are the foundation without which the website may collapse. For each project, we write a spec with a description of all the online store’s functions and algorithms. At the same time, we build a prototype for the visual representation of your future website.

03. Designing UI

When creating a design, we take into account your wishes and marketing trends to make sure that the website interface is easy and clear for users (UX / UI) and that it presents a product or service in the most favorable color.

04. Coding and 3rd-party integration

The next stage is the development of the software itself. Our devs code frontend and backend parts. They also connect third-party delivery services, online payment systems, emailing, etc.

05. Quality Assurance. Testing

Testing the quality of the work is one of the most important parts of the development process. Our QA experts check whether the website is built in accordance with mockups, cross-browser, and adaptability standards. We go over all the functionality of your online store using test cases compiled specifically for your project.

06. Launch and tech support

When you approve the results, we move the web app to your server. Our experts will help you with server and domain settings, connect SSL certificates, and advise on other matters. The warranty on the developed product is valid for 6 months. During this time, we eliminate any problems or errors free of charge.

You need a custom website (instead of CMS), when you got:

Lots of items and need an easy search

If you have tens or even hundreds of thousands of products, you should pay attention to the ease of searching through them. Your customers should be able to intuitively use the online store and find the right product within no more than 3 clicks.

Various marketing tools

To take over competitors, you need to retain the customer by all means. The bigger your online store, the more complex and sophisticated the website's marketing functionality should be. Cumulative discount system, product gift, volume discount, free shipping, email reminders, related products, package offers—all these should work smoothly in one system, with a user-friendly interface and performance analytics.

Complicated order fulfillment process

In big organizations, numerous departments work and communicate with each to fulfill orders. With a custom online store, you can automate the coordination between marketing, sales, accounting, and logistics departments.

Many partners

Have many suppliers or wholesalers? Automate your work with them or give your partners additional features, and they will surely appreciate it. With user accounts in place, you'll make the job easier for both yourself and them.

Complex management

The bigger the store, the more people work for you: sales, support, content management, analysts, SEO specialists, marketers. Each of these roles should’ve its own function with clear separation and logging of actions.

Unique workflows

Creating a custom online store is not an easy task. You should give it to seasoned developers who have experience in this industry. It's also worth thinking about building MVP for your online store. This will allow you to test a mini-version of the product and understand how to develop it further.
