Matthew Timion's Review Sourced from Google
I had the privilege of working with Atwix during a Magento 1 -> Magento 2 (Adobe Commerce) migration. Our e-commerce product was already highly customized and a bit "out of the box" in terms of implementation.Atwix was professional, detail oriented, and regularly met with us to ensure all of our needs were met, the product was fully scoped, and helped ensure success. They went above and beyond in terms of developer resources and expertise.Their deep knowledge of the Adobe Commerce platform helped reduce costs and made the whole process wonderful.

Having known Slava and a bunch of people from his team for the better part of a decade, I can attest to their remarkable dedication, intelligence, and leadership in the ecommerce development realm. It's no surprise to see Atwix being recognized for their work. This photo from Meet Magento New York where they receive a reward on behalf of their customer is just one of the many testaments to the outstanding service and commitment they provide to their clients. Congratulations, Slava and team! Keep setting the standard in the industry.P.S. Slava always knows which camera to look at.

From my initial consultation to the completion of the development process, the entire team at AppStem has been a pleasure to work with. With so many Mobile App Development companies to choose from, it's important to chose one who is willing to understand your needs and clearly outline a game plan before getting into development. If you're looking for more of a partner than just an agency, you're in good hands with AppStem.

Frequently Asked Questions About eCommerce Companies
What services do eCommerce agencies provide?
ECommerce companies offer development and design services that cover the entire digital commerce ecosystem. Primarily, they ideate, design, build, maintain, and optimize web sites for Shopify, Magento, WooCommerce, BigCommerce, and custom platforms.
Their core eCommerce portfolio is often complemented by digital marketing services such as search engine optimization (SEO), pay-per-click (PPC), content marketing, and conversion rate optimization (CRO), to name a few. Other key services include performance tracking, audience research, product listing optimizing, inventory management, sponsored ad management, and online marketplace management for Amazon, eBay, and Etsy.
How much do these services cost?
ECommerce web development costs from $5,000 to $20,000+, with the platform choice and development complexity accounting for the biggest fraction of the cost. Namely, the platform determines how much of the work is handled out of the box and how much of custom development eCommerce providers will need to do. Businesses can choose between DIY website builders, platform-based builds with customizations, and bespoke builds.
Of the three, platform-based builds with agency customizations are the preferred choice among businesses, wherein the cost is affected by the design of the storefront, the UX flows, the checkout and cart customization requirements, the product catalog structure, and the additional integrations pertaining to payment, shipping, and inventory. Here’s what to expect:
Web development: $3,000 to $20,000
Front-end development: $3,000 to $10,000+
Back-end development: $5,000 to $20,000
For bespoke and enterprise builds, the price can exceed $50,000 for the combined development effort.
How long does it take eCommerce companies to build a website?
On average, eCommerce agencies need between 4 and 7 months to build a fully-functioning, responsive eCommerce site. The work is divided into design, wireframing, web development, and marketing preparations. Here’s how long each phase entails:
CMS and web hosting: 1 to 2 weeks
Objectives defining and information architecture planning: 1 to 3 weeks
Low-fidelity wireframing: 1 to 2 weeks
High-fidelity wireframing: 2 to 3 weeks
Web development: 4 to 10 weeks
Marketing and brand preparation: 4 to 6 weeks
Launch and final quality assurance: A few days
Are there additional costs for eCommerce development services?
Yes, the majority of eCommerce development projects come with additional costs for hosting, domain fees, premium themes or plugins, payment gateway fees, and third-party app integrations. In addition to the base fee for the B2C/B2B eCommerce agency, businesses also need to budget for maintenance, security updates, content uploads, inventory setup, and performance optimization.
How long after working with eCommerce agencies businesses typically see ROI?
While benefits related to inventory visibility and automated order processing can be seen almost immediately, considerable return on investment (ROI) can be experienced within 6 to 9 months after working with eCommerce companies. The value comes in the form of reduced manual order processing, better stock accuracy, faster order fulfillment, lower administrative overhead, and better customer service.
