Custom ecommerce development becomes relevant when an off-the-shelf store can no longer handle the way a business actually sells. The companies below work on projects ranging from custom storefronts and marketplaces to ERP integrations, headless commerce, mobile shopping apps, and large-scale platform migrations. The list focuses on European providers with verifiable ecommerce or custom web development capabilities.
Gilzor works on custom ecommerce products for startups and small to medium-sized businesses, including online stores, marketplaces, and platforms where commerce is part of a broader web or mobile product. Its ecommerce offering covers custom builds rather than limiting projects to a particular ready-made storefront system.
The team can handle the surrounding product work as well, including business analysis, UI/UX design, frontend and backend development, QA, and support after release. This setup is relevant when a project includes unusual workflows, marketplace logic, integrations, or functionality that does not fit neatly into a standard ecommerce template. Gilzor has offices in Warsaw and Limassol.
Elogic Commerce concentrates specifically on ecommerce rather than treating it as one service among many. Its work covers B2B, B2C, and B2B2C platforms, with projects involving enterprise replatforming, marketplaces, international rollouts, and connections between ecommerce systems and ERP, CRM, and PIM software.
The technology range includes Adobe Commerce, Shopify Plus, BigCommerce, Salesforce Commerce Cloud, and commercetools. This makes Elogic particularly relevant to established retailers, manufacturers, wholesalers, and distributors dealing with complex catalogs, pricing rules, back-office systems, or several storefronts. The company is headquartered in Tallinn and maintains several other European locations.
A-listware combines web development with dedicated engineering teams and broader software development services. Its web portfolio explicitly includes ecommerce, from relatively straightforward stores for newer businesses to custom solutions intended for larger operations. The company also works on web portals and applications connected to existing corporate systems.
Its ecommerce experience extends into integrations. Published project information covers Shopify, WooCommerce, Etsy, eBay, Amazon, and shipping providers, while its development stack includes technologies such as React, Node.js, PHP, .NET, Java, Python, and Go. This breadth can be useful when the storefront is only one part of a larger operational platform.
Scandiweb has a strong ecommerce focus, particularly around Magento and Adobe Commerce, but its technical coverage is considerably wider. Services listed by the company include ecommerce integrations, B2B ecommerce, headless development, BigCommerce, Salesforce Commerce Cloud, SAP Commerce Cloud, PWA development, and ecommerce design.
For companies running established stores, the agency also handles areas that become increasingly important as traffic and technical complexity grow, such as hosting, performance work, Magento migration, checkout optimization, and ongoing support. Its headquarters and a substantial part of its ecommerce operation are based in Riga.
OSKI Solutions develops ecommerce systems across Shopify, Magento, and WooCommerce while also taking on custom and headless storefronts. Its service scope covers the storefront itself as well as catalogs, checkout, payments, customer accounts, fulfillment connections, and the integration layer behind them.
There is a strong engineering angle to its ecommerce work. OSKI describes projects involving catalog synchronization, custom plugins, payment and shipping connections, ERP and PIM integrations, Next.js storefronts, cloud infrastructure, and performance engineering. It is therefore more relevant to technically involved ecommerce projects than businesses simply looking for a preconfigured theme.
Chilliapple works on ecommerce websites for businesses that need more customization than an off-the-shelf store normally provides. Its ecommerce work includes store design and development, platform migration, payment gateway connections, API integrations, custom themes, updates, and ongoing technical work.
The company works with widely used ecommerce systems including Magento, Shopify, and WooCommerce. This makes it a practical option for businesses that want to stay within an established platform ecosystem while customizing the customer experience, integrations, and underlying store configuration.
Itexus is primarily known for custom software and fintech development, but its portfolio also contains ecommerce systems and ecommerce application work. One published project involved an online B2C ecosystem connecting tire suppliers, installers, customers, and lenders, with purchasing, recommendations, warranties, installation, and financing brought into the same platform.
For ecommerce projects, its broader software background is most relevant when payment, financing, personalization, backend processing, or mobile functionality sits alongside the storefront. Itexus also works on ecommerce applications with backend systems, secure transactions, inventory-related functionality, and integrations.
Lengreo approaches ecommerce from both the development and digital growth sides. Its dedicated custom ecommerce development service covers storefronts built around individual business requirements rather than relying entirely on standard themes and plugin combinations.
Development services include custom storefronts, unique ecommerce features, checkout modifications, platform migration, mobile-first design, and integrations with external systems. Because Lengreo also provides marketing services, it may make more sense for businesses that want development and customer acquisition work handled within a closely connected setup rather than by separate agencies.
ScienceSoft works on ecommerce as part of a broader custom software portfolio. Its ecommerce delivery process includes discovery, customer experience analysis, architecture, functional planning, development, testing, deployment, and continued evolution after the first release.
The company is better suited to projects where the commerce platform needs to interact with existing business software than to small standalone stores. Its ecommerce work covers areas such as webstores, platform migration, back-office automation, multichannel commerce, integrations, QA, and ongoing maintenance.

SoftPro is a Warsaw-based custom software and web application development company working with frontend, backend, CMS, cloud, and Microsoft technologies. Its main services are broader than ecommerce alone, but the company has developed a social commerce platform that combines product promotion, social interaction, influencer marketing, and ecommerce functions.
Its technology coverage includes .NET, Azure, ASP.NET, React, Vue.js, Node.js, WordPress, and Umbraco. SoftPro is therefore more relevant when ecommerce needs to be developed as a custom web application or integrated business platform rather than configured as a conventional Shopify or Magento store.

Mobian develops ecommerce software as well as mobile applications and marketplace products. Its published ecommerce material describes custom online stores, backend systems, shopping flows, payment gateway integrations, and mobile applications that allow customers to browse offers, place orders, access accounts, and interact with businesses.
Marketplace development is another relevant part of its work. Mobian develops applications connecting buyers and sellers and can handle supporting functions such as transaction records, personalization, and integration with the broader ecommerce environment. This makes the company particularly relevant when commerce extends beyond a standard desktop storefront.
Edvantis handles ecommerce development within a wider software engineering practice. Its ecommerce work includes custom websites, mobile applications, headless commerce, integrations, platform modernization, analytics, and security testing.
A useful part of this offering is the emphasis on existing platforms as well as new development. Businesses can use the company for legacy modernization, migration, localization, third-party integrations, or additional engineering capacity rather than replacing an entire ecommerce system at once. Engagement models include dedicated teams and staff augmentation alongside managed project delivery.
Instinctools works on custom ecommerce websites and platforms for different business models, including consumer stores, B2B commerce, and marketplace-style products. Its engineering services cover frontend and backend development, integrations, modernization, and audits of existing systems.
The company works with both general web technologies and ecommerce or CMS platforms, including Shopify, OpenCart, and WordPress. React, Vue, and Angular can be used on the frontend, while external payment processors and CRM systems can be connected to the commerce environment. This gives businesses room to combine established platforms with custom components.
Rishabh Software develops custom ecommerce websites and applications while also working with established open-source store platforms. Its ecommerce engineering covers shopping carts, mobile applications, payment gateways, CRM connections, marketing tools, platform upgrades, and ongoing maintenance.
This combination is useful for companies that want to retain an existing ecommerce foundation but need custom functionality around it. The company also works on omnichannel and multichannel retail systems, so projects can extend beyond a single web storefront into connected customer and operational channels.
iFlair works with businesses that want to build ecommerce systems on established platforms while adding custom functionality around catalog management, checkout, payments, and vendor operations. Its ecommerce capabilities include Shopify, WooCommerce, Magento, and PrestaShop development as well as custom ecommerce solutions.
The company also develops multivendor platforms and ecommerce applications, which broadens its use beyond conventional single-retailer stores. Payment gateway integration and ongoing maintenance are available as part of the same development scope, making it suitable for businesses that want one technical team to build and maintain the commerce environment.
Net-devs takes a broader enterprise engineering approach rather than positioning itself as a dedicated ecommerce agency. Its services cover enterprise development, modern frontend engineering, cloud platforms, AI integration, prototyping, QA, and ongoing software evolution. The company works across .NET, JVM, Node, Python, and Go, with React, Angular, and Vue used for frontend development.
For commerce teams, that broader engineering background is most relevant when the requirement goes beyond configuring an ecommerce platform and involves a substantial custom application, cloud infrastructure, API layer, or frontend. Its public service pages currently focus on enterprise software rather than ecommerce as a standalone practice, so businesses looking specifically for Shopify, Magento, or WooCommerce expertise may find a specialist agency elsewhere on this list more suitable.
The right custom ecommerce development company depends less on the size of the agency and more on what the store actually needs to do. A straightforward Shopify or WooCommerce project calls for a different skill set than a B2B platform with custom pricing, a multivendor marketplace, or a headless store connected to ERP, CRM, and PIM systems. Before choosing a team, it makes sense to look closely at relevant project experience, platform expertise, integration capabilities, and the level of support available after launch.
The companies on this list cover a fairly wide range of ecommerce needs, from platform-based stores and mobile commerce to custom marketplaces and enterprise systems. For businesses comparing custom ecommerce web development companies in Europe, the most useful next step is to narrow the list according to technical requirements and then discuss the actual project scope with a few suitable teams. A company that understands the business logic behind the store, not just the storefront itself, is usually a better fit for a custom build.
