Everything your BigCommerce store needs, from one team

Most stores stall because design, integrations, and marketing are split across different vendors. We plan them together, so every change supports sales.

BigCommerce store development

Complete store builds planned around your catalog, checkout, shipping rules, and the systems you already run. You get a store that is ready to scale on day one, not one that needs rework after launch.

Migration to BigCommerce

Products, variants, customers, and order history moved from Magento, WooCommerce, Shopify, or a custom cart, with 301 redirects mapped so your search traffic follows you.

Theme customization

Custom menus, clearer product pages, quick add-to-cart, and mobile-first layouts built on Stencil and tested on staging before anything goes live.

B2B and wholesale

B2B Edition setup, log in for pricing, customer price lists, quick order, reorder, quotes, and purchase orders for distributors and manufacturers.

API integrations

ERP, CRM, Klaviyo, marketplaces, GA4, and Cloudflare connected through BigCommerce APIs and webhooks, so inventory, pricing, and orders stay in sync.

Headless storefronts

Fast Next.js storefronts built with BigCommerce Catalyst and the GraphQL Storefront API, for brands that need custom experiences or several storefronts.

AI search and personalization

Search that understands natural language and typos, better product discovery, and recommendations shaped by what each shopper actually does.

BigCommerce SEO

Technical SEO, clean URLs, structured data, and page speed work that helps your products rank on Google and show up in AI answers.

Conversion optimization

Checkout fixes, trust signals, upsells, and A/B tests that turn more of your current traffic into orders.

Is this the right fit?

We would rather be upfront so you do not waste a call.

We are a strong fit if you

  • Sell on BigCommerce and want more revenue from your current traffic
  • Plan to move to BigCommerce from Magento, WooCommerce, Shopify, or a custom cart
  • Sell B2B or wholesale and need pricing, quoting, or reorder features
  • Need your store connected to an ERP, CRM, or marketplaces
  • Are considering a headless storefront or AI-powered search

We are probably not the right fit if you

  • Only need a small one-off theme tweak
  • Have not chosen an ecommerce platform and do not want to consider BigCommerce
  • Want a template store launched without any planning

Questions before you reach out

Still deciding? These are the questions US store owners ask us most.

Get my free audit
How much does BigCommerce development cost?

It depends on scope. The main factors are a customized theme versus a headless build, catalog size, migration complexity, the number of integrations, and B2B requirements. Your free audit and discovery call give you a scoped estimate before you commit.

How long does a BigCommerce project take?

A store with a customized theme often takes several weeks. Migrations, B2B builds, and headless storefronts can take a few months. We share a timeline once scope is agreed.

Will moving to BigCommerce hurt my Google rankings?

Not when the migration is done carefully. We map 301 redirects for every URL that earns traffic, carry over titles, descriptions, and structured data, and monitor Google Search Console after launch.

Can you improve a store that is already live?

Yes. Many projects start with an existing store. We fix speed, search, product pages, and checkout, then keep improving conversions over time.

Do you build B2B and headless BigCommerce stores?

Yes. We set up B2B Edition features such as price lists, quotes, and purchase orders, and build headless storefronts with BigCommerce Catalyst and Next.js.

What happens after I submit the form?

A BigCommerce specialist reviews your request and emails you to confirm the details of your audit. You can also book a call straight away using our online calendar.
