BigCommerce gives merchants plenty of room to customize a storefront, but that flexibility also means projects can become fairly technical once design, checkout, integrations, catalogs, and performance enter the picture. The companies below cover different parts of that work, from custom UX and theme design to replatforming, B2B commerce, headless builds, and ongoing optimization.
Gilzor handles BigCommerce web design within a broader ecommerce product development process. Its work covers interface design, web development, testing, and post-launch support, with UX decisions tied to how shoppers actually move through the store rather than treating the storefront as a collection of static pages.
The company also works on custom ecommerce products, marketplace development, platform switching, integrations, and mobile commerce. That wider engineering scope is useful when a BigCommerce project involves more than a new visual theme and needs custom business logic or connections with other systems.
Codal combines ecommerce strategy, experience design, engineering, and BigCommerce implementation. Its design capabilities include UX, service design, visual systems, and brand work, while the commerce side extends into B2B and B2C storefronts, integrations, and custom platform development.
The company has a Chicago office and works on projects where the storefront has to fit into a larger ecommerce operation. That can include custom integrations, complex customer journeys, and ongoing conversion or performance work rather than a one-time visual redesign.
A-Listware performs ecommerce engineering with a broader software development and team extension model. Its ecommerce work includes custom software, interface design, backend development, integrations, testing, and technical support, giving clients access to specialists beyond the storefront itself.
The company can be useful for ecommerce projects where design work is tied to custom functionality or existing business systems. Its web design process covers user research, UX/UI work, development, and QA, while its ecommerce practice includes both B2B and B2C platforms and supporting software.
DigitlHaus focuses closely on Shopify and BigCommerce, with BigCommerce projects spanning store design, UX/UI, responsive layouts, theme design, custom development, migrations, integrations, and ongoing optimization.
Its BigCommerce work covers both D2C and B2B brands. Design is treated as part of a wider commerce system, so projects can move from wireframes and design systems into custom themes, app integrations, APIs, and post-launch work. The company is particularly relevant when an existing store has accumulated technical or UX problems and needs a deeper redesign rather than cosmetic changes.
Americaneagle.com has a dedicated BigCommerce practice covering design, development, migration, integration, and post-launch support. Its work spans B2B and B2C stores, including projects involving large catalogs and connections between BigCommerce and ERP, CRM, POS, shipping, payment, and PIM systems.
The company develops both conventional BigCommerce storefronts and more flexible experiences using technologies such as Stencil, Catalyst, and Makeswift. Multi-Storefront implementation is another part of its offering, which is useful for organizations managing several brands, markets, or customer groups from one commerce environment.
Itexus develops web applications, digital marketplaces, and ecommerce-related products where commerce functionality forms part of a larger software system. Its project work covers product design, frontend and backend engineering, cloud infrastructure, integrations, testing, and continued development after launch.
The company has evaluated BigCommerce Multi-Vendor Marketplace alongside other ecommerce technologies during marketplace architecture work. Its broader strength is custom software rather than template-based storefront production, making the company more relevant when commerce features have to connect with proprietary workflows, external services, or a larger digital platform.
Anchor Group builds BigCommerce websites for B2B and B2C companies, with a particularly strong focus on connecting storefronts to other business systems. Its work covers implementation, theme development, customization, integrations, and ongoing technical support.
NetSuite integration is a substantial part of its ecommerce practice. That combination can suit merchants that need BigCommerce to exchange product, customer, inventory, and order information with an ERP rather than operating as a largely independent store.
IntuitSolutions concentrates heavily on ecommerce and provides custom solutions for BigCommerce and Shopify. Its BigCommerce work extends from storefront design and development to more technical customization, B2B functionality, application development, and ongoing optimization.
Because the team is US-based, projects can be handled without splitting communication between a domestic client-facing operation and an offshore development group. Its range covers entry-level stores as well as more involved ecommerce requirements, making it suitable for businesses that expect their storefront to change over time.
21Century.Tech takes a software engineering approach to web projects, using senior developers alongside AI-assisted development workflows. Its work includes full-stack features, landing pages, third-party integrations, legacy refactoring, automated testing, deployment, and technical documentation.
For ecommerce teams, this model is more relevant when the project involves custom functionality around the storefront rather than conventional theme design alone. Third-party integrations, frontend components, supporting applications, and custom business logic can sit within the same engineering engagement.
Human Element develops ecommerce sites for retailers and B2B companies and maintains a dedicated BigCommerce practice. Projects range from new storefronts and site refreshes to platform migrations, custom templates, ERP connections, and technical work supporting existing ecommerce teams.
Its experience covers both consumer and business purchasing models. That matters for BigCommerce implementations where account structures, pricing, catalogs, or internal integrations make the customer journey more complicated than a conventional retail checkout.
EYStudios focuses on ecommerce design, development, maintenance, and digital marketing, with BigCommerce forming a significant part of its project portfolio. Rather than relying on standard themes, the agency creates custom storefront designs around individual brands and their catalog structures.
Its BigCommerce projects include complete store transformations as well as work on existing sites. The company can therefore cover both the visible customer experience and the technical changes required to put that design into production.
Coalition Technologies combines BigCommerce web design and development with SEO and paid marketing services. This creates a different type of engagement from a development-only company because storefront structure, landing pages, technical changes, and traffic acquisition can be considered together.
Its BigCommerce services include custom design and development along with work intended to improve the performance of an existing ecommerce site. The company is a practical option for merchants that want website changes handled alongside ongoing search or advertising work.
Dinarys works across several major ecommerce platforms, including BigCommerce, and handles both B2C and B2B implementations. Its services cover initial store development as well as migration, custom functionality, integrations, performance improvements, and continued technical support.
The company is particularly relevant when a merchant is replatforming rather than starting with an empty store. Catalog information, existing functionality, third-party tools, and integrations all have to survive that transition, so design work is handled alongside the technical migration process.
DotcomWeavers focuses largely on B2B ecommerce and builds BigCommerce storefronts around more complicated purchasing and operational workflows. Its projects can include custom UI/UX, headless development, B2B Edition implementations, ERP integration, migration, and automation.
This makes the company particularly relevant to manufacturers and distributors where website design cannot be separated from pricing rules, inventory, quotes, account management, and order processing. DotcomWeavers is based in New Jersey and continues working with stores after launch through integration and optimization services.
Binary Anvil works with BigCommerce alongside Adobe Commerce and Shopware. Its commerce projects bring together discovery, UX and interface design, frontend engineering, architectural work, integrations, data migration, and managed support.
BigCommerce projects include migration from other ecommerce platforms and customization of marketplace themes to fit existing brands. The company's engineering background makes it more relevant where store design has to sit alongside ERP, PIM, CRM, or other integrations rather than functioning as an isolated frontend project.
A BigCommerce project can be fairly simple, or it can turn into a much bigger technical job once integrations, custom checkout logic, B2B features, or platform migration enter the picture. That is why the right fit depends less on the size of the agency and more on what the store actually needs. Some teams are better suited to design-heavy storefront work, while others make more sense for complex development, ERP connections, or ongoing ecommerce support. Before choosing, it is worth comparing relevant BigCommerce experience, the depth of the development team, and how much support will be needed after launch. A clear scope at the start usually makes that comparison much easier.
