Best BigCommerce Agencies and Developers (2026): 14 Compared by Buyer Type, Including Us

On 9 October 2026 we put one buyer question to five assistants (ChatGPT, Claude, Gemini, Perplexity and Google’s AI answers): what is the best agency for BigCommerce B2B Edition? We collected 14 answers. Across that question and three related ones, 15 answers linked to a list of BigCommerce agencies, and those lists came from 12 sites.

On 11 October we read all 12 pages. Ten are lists of BigCommerce agencies. The other two are about moving a store off BigCommerce. Eight of the ten are published by an agency, and seven of those eight put their own firm first. The other two sit on single-topic list sites from one publisher. Three of the 12 pages link to BigCommerce’s partner directory, the one place a tier can be verified.

So we started from the directory. We counted every tier, picked US agencies whose own sites name one of four kinds of buyer, and kept only what is written on each firm’s site and its directory profile. Each profile ends with the links we used.

Who wrote this. FactoryJet builds BigCommerce stores for a living, and we put ourselves on this page. No firm paid or asked to be listed. Our entry is written to the same template as the other 13. Keep the author in mind with any agency list, this one included.

Eight terms come up on every agency site, so here they are in plain words. BigCommerce is a platform for running an online store, sold as a subscription. A BigCommerce agency or developer designs and builds stores on it. B2B, or wholesale, is selling to other companies on agreed price lists and payment terms. B2B Edition is BigCommerce’s add-on set of tools for that kind of selling. Stencil is BigCommerce’s standard theme system. Headless means the part shoppers see is built separately and fetches products, prices and carts from BigCommerce, and Catalyst is the framework BigCommerce makes for it. An ERP is the back-office system where orders, stock and accounts are kept.

The 14 firms in one table

Start with the Suits column. The rows that share your kind of business are the profiles to read first.

How this list was made

1. Measure the demand. “BigCommerce developers” gets 320 US Google searches a month, and the related searches for agencies and partners bring the group to about 830 (DataForSEO, October 2026). We ran four of those searches on 11 October, and an AI answer appeared in Google’s results for all four.
2. Open the 12 lists that assistants link to. They showed us which firms get named again and again. Nothing on this page is taken from them.
3. Start from BigCommerce’s own directory. We filtered it by tier and by region, counted each group and opened the profile of every firm we considered.
4. Keep firms with a US head office. Each of the other 13 shows a US headquarters on its directory profile and a US address on its own site.
5. Use two sources per firm. What a firm builds, and for whom, comes from its own site. Its tier and badges come from its directory profile. Both were opened on 11 October 2026.
6. Mark a claim as a claim. When a firm states a project count, a client name or a result, the profile says the firm states it.
7. Group by buyer, with no scores. Each profile says who the firm suits and gives one question to put to it. There are no star ratings and no positions.
8. Take prices from BigCommerce. Plan prices come from its price page and build ranges from its cost guide. No agency’s price is estimated here.

BigCommerce partner tiers, counted

BigCommerce’s partner directory listed 755 agency partners on 11 October 2026. It sorts them into four tiers: Elite, Preferred, Partner and Enrolled. Enrolled is where everyone starts. BigCommerce’s partner page says you instantly become an enrolled partner when you sign up, that each new badge brings more perks, and that partners at higher tiers get a partner marketing manager.

The table below counts each tier twice, first with no filter and then with the directory’s North America region filter on.

Elite and Preferred together are 26 of the 755 listings, about 3 in every 100. The public pages we read do not say what an agency must do to reach each tier. That makes a tier a useful first filter and a poor final answer, because it cannot tell you whether the firm has done your kind of project.

The directory also shows badges. The one that matters for wholesale is B2B Specialized. On 11 October, 76 partners carried it, and 60 of those list North America as a region they serve.

Of the 13 other firms on this page, the directory listed 4 as Elite, 6 as Preferred, 2 at the Partner tier and 1 as Enrolled, and 11 carry the B2B Specialized badge. Read the badge on the directory profile itself. Tiers move, and the wording on an agency site or in its profile text can describe an earlier tier.

The 14 BigCommerce agencies and developers, by the buyer they suit

Four groups, then us: B2B and wholesale, mid-market consumer brands, headless builds and migrations. Within a group the order means nothing.

BigCommerce agencies for B2B and wholesale

Firms whose own pages put B2B first. Each comes at it from a different side: dealer self-service, wholesale on standard BigCommerce, the NetSuite connection, and parts and trade supply. All four carry the B2B Specialized badge in the BigCommerce directory.

IntuitSolutions says it has specialized in migrating, developing and customizing BigCommerce stores since 2009, and its directory profile says its team works on BigCommerce all day, every day. Its B2B page makes a point buyers rarely hear from an agency: B2B Edition is not always required, and most merchants can start selling B2B on standard BigCommerce with the right additions. It builds account-based pricing, payment terms, quick ordering and custom checkout, and sells its own checkout app. It says its migration team is fully in-house.

BigCommerce agencies for mid-market consumer brands

Firms that lead with design and marketing for consumer brands. DTC stands for direct-to-consumer, where the brand sells to the shopper with no retailer in between. All three sit at the Preferred tier in the directory, and all three sell marketing services alongside the build.

Groove Commerce

Base: Baltimore, Maryland. Type: Design, development and marketing for BigCommerce stores. BigCommerce directory tier: Preferred, with the B2B Specialized badge.

Groove Commerce designs, builds and markets ecommerce stores, and its directory profile gives 2007 as its founding year.

BigCommerce developers for headless and composable builds

Three firms whose pages name headless or composable builds on BigCommerce. In a headless build the storefront is written separately from the commerce engine. In a composable one you choose each part of the stack yourself. Catalyst is the headless storefront framework BigCommerce makes, built with Next.js.

BigCommerce agencies for migrations and replatforming

These three put replatforming first. They differ in the routes they name. 1Digital Agency lists six platforms it moves stores between, Forix lists three routes into BigCommerce, and Classy Llama works across four platforms.

1Digital Agency

Base: Miami, Florida, per its site footer and directory profile. It was founded in Philadelphia in 2012. Type: Platform migrations, BigCommerce builds and search marketing. BigCommerce directory tier: Enrolled.

Dan Kogan started 1Digital in Philadelphia in 2012. Its migrations page says it moves stores to and from BigCommerce, Shopify Plus, Adobe Commerce, WooCommerce, Volusion and Salesforce Commerce Cloud, and has completed 200+ migrations. It says it maps, moves and verifies the catalog, customers and order history, and redirects every old web address so shoppers and search engines land in the right place on launch day.

What is the best agency for BigCommerce B2B Edition?

That is the question a buyer asked, word for word. Before you choose a firm, check what B2B Edition is and whether you need it. This is how BigCommerce’s own pages describe it, in the wording we found on 11 October 2026:

• What it adds. BigCommerce’s developer documentation lists company accounts, sales quotes, invoice management for purchase orders paid on net terms, user roles for buyers and staff, and sales staff who can act for a client.
• The Buyer Portal. A private account area where a business customer requests quotes and pays invoices. The documentation says it works with Stencil themes, Catalyst and custom headless storefronts.
• How it is sold. The app listing describes B2B Edition as building on BigCommerce’s Enterprise plan, so ask BigCommerce or your agency which of today’s plans that means for you.
• What standard BigCommerce already has. The price page shows customer groups on the Growth plan and above, and price lists, which set custom prices per product for a customer group, on the Performance plan only.

IntuitSolutions makes the practical point on its own B2B page: B2B Edition is not always required, and most merchants can start selling B2B on standard BigCommerce. A seller with a few customer groups may not need it. A seller whose buyers need company accounts with several users, quotes and invoices on terms usually does. BigCommerce’s B2B page says B2B and B2C can run from the same place.

Groove Commerce, Codal and 1Digital Agency also describe B2B Edition or B2B portal work on their sites. FactoryJet sets up B2B Edition with company accounts, price lists, quotes and payment terms, and connects it to whichever system is the master for prices and stock. See BigCommerce B2B Edition development. For portals on any platform, read B2B ecommerce.

What BigCommerce and a build cost

Two prices get mixed up: what you pay BigCommerce for the plan, and what you pay an agency to build the store. Here is the first, copied from BigCommerce’s price page on 11 October 2026. BigCommerce can change these, so check the page before you rely on them.

Two notes on the table. BigCommerce measures sales for the caps as gross order value minus 10%. And the last column depends on a list BigCommerce keeps of embedded payment providers, which includes Stripe, PayPal, Adyen and Klarna. Orders paid through those carry no extra charge from BigCommerce. Orders paid through any other provider carry the percentage shown. Our post on BigCommerce and Shopify after the 2026 fee change works through what that means for a small store.

For the build, BigCommerce publishes ranges of its own in its 2026 ecommerce website cost guide, in a table it credits to Monocubed.

On the pages we read, none of the 13 other firms shows a fixed price for a BigCommerce build. DigitlHaus says it scopes the whole project upfront so the client knows the precise cost before work starts. FactoryJet gives two fixed prices in writing after a short scoping call, one for the build and one for ongoing support.

Which kind of BigCommerce agency you need

Each line below is something a buyer might say. Find yours, and it names the firms to call.

Choosing a BigCommerce developer in six steps

Each step opens to show the detail.

Questions to put to a BigCommerce agency before you sign

1. Which systems have you joined to BigCommerce, by name? Anchor Group names NetSuite on its site. Ask every firm about the system you run.
2. Do we need B2B Edition? IntuitSolutions says not always. A firm that says yes should be able to name the feature that decides it.
3. Stencil or Catalyst, and why? Americaneagle.com and MoJo Active both name the two. A good answer starts from your store and the team that will run it.
4. How are old web addresses mapped to new ones, and who tests them? 1Digital Agency says it redirects every old web address. Ask to see the sheet from a past project.
5. What is your tier in BigCommerce’s directory today? Check the answer against the profile.
6. Will you show working software on our data before a contract? Your own catalog and price rules expose problems a prepared demo hides. FactoryJet shows working software on the buyer’s own data before a contract.
7. When the project ends, who holds the code, the custom apps and the accounts? Get it into the contract that you do.

FactoryJet on BigCommerce: what we build

FactoryJet has built commerce systems since 2014 and has served 500+ businesses. Bhavesh Barot, the founder, takes the first call on every project himself. We work remotely with US clients and hold calls in US business hours.

• Stores. Custom themes, multi-storefront setups and headless storefronts on Next.js. See BigCommerce development.
• B2B Edition. Company accounts, price lists, quotes, payment terms and buyer portals. See BigCommerce B2B Edition.
• Integrations. NetSuite, Odoo, SAP Business One, ERPNext and custom ERPs, plus QuickBooks, Xero, HubSpot, EDI and punchout catalogs.
• Migrations. From Magento and WooCommerce, with products, customers, orders and content moved and a redirect for every old web address. See replatforming.
• AI agents. Agents that prepare quotes, purchase orders and sales orders in the store and the ERP, with a person approving before anything posts. See ERP AI agents.

A BigCommerce store on a custom theme usually takes 3 to 5 weeks. A B2B Edition build or a migration takes 5 to 8 weeks, and a headless build 8 to 14 weeks. You get two fixed prices in writing after a short scoping call, one for the build and one for ongoing support. Once the store is live, the integrations, the APIs, the AI and the routine maintenance stay our job, so they never land on your team. Everything we build belongs to you.

If the platform itself is still an open question, these pages cover the choices around it: Shopify Plus agencies for US brands, ecommerce development agencies in the USA, B2B ecommerce development agencies for portals and how to choose an ecommerce development agency.
