BigCommerce is a software-as-a-service commerce platform designed for growing brands, mid-market retailers and enterprise merchants. It offers built-in features such as multi-currency selling, product variants, B2B tools and strong API access, while also supporting headless commerce, where the storefront is built separately from the backend. Because the platform is flexible, results depend heavily on how well it is configured, customised and integrated with other systems.
This guide from Software Outsourcing Journal introduces five agencies and development firms that are known in the BigCommerce community. For a wider view of e-commerce and web technologies, browse our collection of Software Development Technologies.
Why Merchants Choose BigCommerce
One of the main attractions is the open SaaS model. Merchants receive hosting, security updates, uptime management and core commerce functionality as part of the subscription, which reduces the burden of maintaining servers and patching software. At the same time, APIs and webhooks allow developers to connect the store with enterprise resource planning systems, customer relationship management tools, marketing automation, warehouse software and custom applications.
BigCommerce also supports headless and composable architectures. A brand can use a modern front-end framework such as Next.js to deliver a fast, highly customised shopping experience while relying on BigCommerce for catalogue, cart, checkout and order management. This approach appeals to companies that want design freedom, content-rich experiences or multiple storefronts sharing a single backend.
B2B commerce is another growing focus. Features such as customer groups, price lists, quote management and company accounts help manufacturers and wholesalers move ordering online. A skilled agency can configure these capabilities and integrate them with existing pricing and inventory systems.
What a BigCommerce Agency Should Provide
Typical services include store setup and theme customisation, migration from another platform, custom app and integration development, headless storefront builds, performance optimisation, search engine optimisation, conversion rate improvement and ongoing support. For larger projects, you may also need discovery workshops, user experience research, data migration planning and training for your internal team.
Migration deserves particular care. Moving products, customers, orders, redirects and reviews from platforms such as Magento, WooCommerce or Shopify involves data mapping and testing. Poor redirect planning can harm search rankings, so experienced partners will manage URL structure and technical SEO as part of the project.

Top 5 BigCommerce Development Companies
1. Corra
Corra is a digital commerce agency recognised for work on enterprise and mid-market projects across platforms, including BigCommerce. It combines strategy, design, engineering and optimisation, and it has experience with both B2C and B2B scenarios. Its teams often handle complex integrations and replatforming programmes where several systems must work together. Merchants that need a senior, process-driven partner for a significant transformation should consider it.
2. Guidance
Guidance is a US-based digital agency with a long history in e-commerce, including implementations on BigCommerce. It offers services such as platform selection, design, development, data migration and ongoing support, with particular strength in B2B and manufacturing. The company often helps clients move from legacy systems or custom-built stores to a managed SaaS platform. Businesses that value consultative guidance in choosing and implementing technology will find its approach useful.
3. Rocket Agency
Rocket Agency is an e-commerce agency that has built a reputation for BigCommerce development, design and growth marketing. It serves growing brands that need a mix of technical build work and performance-focused strategy, including search engine optimisation and paid media support. The ability to combine creative, development and marketing under one roof can simplify communication. Smaller and mid-sized merchants looking for a hands-on partner often shortlist agencies of this type.
4. Lounge Lizard
Lounge Lizard is a New York-based digital agency offering web design, development, branding and e-commerce services, including BigCommerce projects. It emphasises custom design and brand storytelling, which can be useful for retailers that want a distinctive storefront rather than a template-based look. The agency also provides digital marketing and content support. For brands that place a high priority on visual identity and customer experience, it is worth evaluating.
5. Blue Acorn iCi
Blue Acorn iCi is a commerce-focused agency with extensive experience in enterprise platforms and digital experience design. It has supported large retailers and brands with complex requirements, from custom integrations to optimisation programmes. Its background across several commerce platforms can help it recommend sensible architecture rather than defaulting to one tool. Organisations with large catalogues, multiple regions or demanding performance targets may benefit from this depth.
Choosing the Right Partner
Clarify your business model first. A direct-to-consumer fashion brand, a wholesale distributor and a subscription business have very different requirements. Write down your catalogue size, order volume, integrations, markets, languages, payment methods and growth plans so that agencies can scope accurately.
Examine their work, not only their claims. Visit live stores, test them on mobile devices, check page speed and try the checkout process. Ask for metrics such as conversion rate improvement, load time reduction or revenue growth, and find out how much of the result was attributable to the agency’s work.
Ask about technical practices. Do they use version control, staging environments, automated testing and code review? How do they manage theme updates, app conflicts and third-party scripts? Do they follow accessibility guidelines? A disciplined engineering process prevents many of the problems that appear after launch.
Discuss ownership and support. You should own your store, your code and your data, and the agreement should clarify what happens if the relationship ends. Ask about response times for urgent issues, availability during peak seasons and the cost of retainer plans.
Budget and Timeline Expectations
A theme-based store with limited customisation can launch in a matter of weeks, while a complex migration or headless build may take several months. Costs scale with the number of integrations, custom features, design complexity and data migration volume. Beware of very low quotes that omit testing, redirects or integration work, because those gaps usually return as change requests later.
Frequently Asked Questions
Is BigCommerce better than Shopify?
Neither is universally better. Both are strong SaaS platforms, and the right choice depends on features, pricing structure, B2B needs, team skills and ecosystem. Compare them against your own requirements.
Can BigCommerce handle large catalogues?
Yes, the platform is designed to support large catalogues and high traffic, though performance also depends on theme quality, apps and integrations.
Performance and SEO on BigCommerce
Store speed and search visibility strongly influence revenue. Optimise images, limit heavy third-party scripts, use a content delivery network and test Core Web Vitals on real mobile devices. Choose apps carefully, because each addition can affect load time and checkout reliability. For search engine optimisation, ensure clean URL structures, descriptive titles, structured data for products, logical category hierarchies and fast mobile pages. During migrations, map old URLs to new ones with permanent redirects and monitor Search Console for errors. Content such as buying guides and comparison pages can attract qualified traffic, while email and retention programmes increase lifetime value. A strong BigCommerce agency will discuss these topics alongside design and development, since a beautiful store that is slow or hard to find rarely meets its commercial goals.
It is also wise to plan your post-launch roadmap before the first release. Reserve budget for conversion experiments, new integrations, seasonal campaigns and platform updates. Track key indicators such as conversion rate, average order value, cart abandonment and page speed, and review them monthly with your agency. Merchants who treat the store as an evolving product usually outperform those who consider a launch to be the finish line, because small, steady improvements compound over time.
Final Thoughts
BigCommerce gives merchants a solid foundation for growth, but the quality of the build determines the results. Corra, Guidance, Rocket Agency, Lounge Lizard and Blue Acorn iCi offer different combinations of strategy, design and engineering. Shortlist a few, compare proposals carefully and consider a paid discovery phase before committing to a large project.
