Top 20 BigCommerce Development Companies in USA (2026): Specialists, Shopify Shops and the June Fee Change

1 June 2026. BigCommerce renamed its plans and started charging a fee on orders that do not pass through its approved payment providers: 2 percent on Core, 1 percent on Growth, 0.6 percent on Scale (BigCommerce).

A Scale store selling $300,000 a year through a gateway outside the list now pays $1,800 a year for that alone. The fee is charged per order, so it grows with the store.

So the gateway belongs on every Top 20 BigCommerce Development Companies in USA shortlist.

So does a second question. Of the 762 US firms in Clutch’s BigCommerce directory, 659 also list Shopify, and 68 name BigCommerce as their single leading platform (Clutch).

Specialists exist. Most of the directory is not them.

The guide covers the fee, what the work costs, how to tell the specialists from the generalists, and what to settle before launch: whose name is on the store account, the payment contract and every app subscription.

Key takeaways

• 1 June 2026 is when BigCommerce’s new plans and its Open Payment Provider Fee took effect: 2.0% of eligible order value on Core, 1.0% on Growth and 0.6% on Scale (BigCommerce).
• $30,000 and $100,000 are the new trailing-year sales caps for Core and Growth, down from $50,000 and $180,000 (Shopifreaks).
• 68 of 762 US firms in Clutch’s BigCommerce directory name BigCommerce as their single leading platform; 659 also list Shopify (Clutch).
• 21 of 168 first-page reviews across the top 20 mention BigCommerce, fewer than mention Shopify (28) or Magento (25) (Clutch profiles).
• $8.8 billion in merchant sales ran through Commerce.com, BigCommerce’s parent, in Q2 2026, up 14%, while its annual recurring revenue grew 2% (Commerce).
• 70.22% of online shopping carts are abandoned, and 17% of abandoners cite a long or complicated checkout (Baymard Institute).
• 70% of the 5,114 US digital accessibility lawsuits filed in 2025 targeted e-commerce sites (UsableNet).
• $82,619 to $135,980 is the spread between Glassdoor’s BigCommerce developer average and the BLS median for software developers (Glassdoor; BLS).

BigCommerce in 2026: a smaller platform with a new price structure

BigCommerce is a mid-market platform, not a mass-market one. W3Techs finds it on 0.2 percent of the websites whose content management system it can identify, and on 0.6 percent of the e-commerce systems it tracks (W3Techs). Shopify runs 5.4 percent of all websites (W3Techs). Crawl data counts sites rather than sales, so it understates a platform aimed at larger stores.

The stores are growing faster than the platform’s revenue. In the second quarter of 2026, merchants processed $8.8 billion through Commerce.com, the company behind BigCommerce, up 14 percent on a year earlier. Its annual recurring revenue was $360.5 million, up 2 percent, and net revenue retention was 95.8 percent (Commerce). The June pricing change arrived against that background.

The plans changed on 1 June 2026. Standard became Core, Plus became Growth, Pro became Scale and Enterprise became Performance. Base prices stayed the same, but the sales caps dropped: Core now covers up to $30,000 in trailing-year sales and Growth up to $100,000, down from $50,000 and $180,000 (Shopifreaks). Scale caps at $33,333 a month in sales, with 0.9 percent charged above it, and plans upgrade automatically when a store passes its cap (BigCommerce).

The payment fee is the change a developer has to act on. Orders processed through an Open Payment Provider, meaning any gateway outside BigCommerce’s embedded list, now carry a monthly fee of 2.0 percent of that order value on Core, 1.0 percent on Growth and 0.6 percent on Scale. Performance plans, which start at $1,499 a month billed annually, run on contracted terms instead (BigCommerce). A store using a legacy gateway, a regional processor or a B2B payment method now has a line item to price against the cost of switching.

Headless is now a first-party option. Catalyst, BigCommerce’s own Next.js storefront, ships with a UI kit that BigCommerce says draws on more than 4,000 headless implementations on the platform (Catalyst). It sits beside Stencil, BigCommerce’s theme framework. The choice matters for cost, because a headless storefront adds its own hosting, build pipeline and front-end team.

API limits depend on the plan. BigCommerce’s developer documentation lists 20,000 API requests an hour for Standard and Plus stores (150 every 30 seconds) and 60,000 for Pro (450 every 30 seconds), with Enterprise limits set by plan (BigCommerce Developer Center). An ERP or inventory sync that assumes more will fail at the busiest hour of the year.

The market underneath all of this keeps growing. US retail e-commerce reached $340.2 billion in the second quarter of 2026, 17.1 percent of all retail sales and up 12.2 percent on a year earlier (US Census Bureau).

So a BigCommerce brief needs three answers before any firm is compared: which plan the store will sit on at next year’s sales, which payment providers it uses and whether they are embedded, and whether the storefront stays on Stencil or moves to Catalyst.

What BigCommerce development costs in the US

Pay figures for comparable roles spread by $53,361 across four sources.

Glassdoor reports an average of $82,619 for a BigCommerce developer (Glassdoor). The Bureau of Labor Statistics puts the median web developer at $92,650 and the median software developer at $135,980, both in May 2025 (BLS web developers; BLS software developers). ZipRecruiter reports $109,905 for a BigCommerce developer, but it returns exactly the same figure for a Shopify developer, so read it as a general e-commerce developer number (ZipRecruiter).

Glassdoor’s figure is a small, self-reported sample for a narrow title. BLS covers every web or software developer. None of them prices what a BigCommerce build needs most, which is integration work with ERP, inventory and payment systems.

Agency pricing on this list sits high. Fourteen of the twenty firms publish $100 an hour or more, nine of them $150 to $199, and two publish $25 to $49. The median published minimum project is $10,000, from $1,000 to $100,000 (Clutch profiles, read 29 September 2026).

Eight factors decide where a BigCommerce quote lands.

The starting point comes first: a new store, a theme rebuild or a migration from another platform. Then the storefront, Stencil or Catalyst; the catalogue size and product options; ERP, inventory and accounting integrations; B2B features such as price lists and quotes; payment providers, now a cost question as well as a technical one; the apps the store depends on; and the support terms. Ask every vendor to quote integrations one by one, and to list the paid apps its design assumes.

The Top 20 BigCommerce Development Companies in USA, compared

We used Clutch’s directory of BigCommerce developers in the United States, sorted by Clutch Rank and read on 29 September 2026. It lists 762 firms and carried no paid rows on any page when we read it. Firms 2 to 21 below are its top 20, in Clutch Rank order.

Brain Station 23 is placed first because we publish this article. We are US-headquartered and verified on Clutch, but we are not in this directory, and BigCommerce is not a named platform in our published split, so we are not claiming a ranking in it.

The BigCommerce Focus column shows BigCommerce’s share of each firm’s published e-commerce platform work, with the platform that leads it. The # column is this list’s position. Certifications are self-published and unverified wherever they appear.

Team sizes, platform splits, stacks, industries and locations are from each firm’s published Clutch profile, read 29 September 2026. “Best For” is our reading of that data. Founding years come from the same profiles; certifications are not published consistently, so they appear only in the profiles, marked where a firm states them.

1. Brain Station 23

We publish this article and placed ourselves first, so read this as the publisher’s entry. We are not in Clutch’s BigCommerce directory, and our published platform split is 60 percent other systems, mainly nopCommerce, with Shopify and WooCommerce at 20 each. Two of our eleven first-page reviews are BigCommerce work: an e-commerce site and mobile app for a food company in 2025, and an ongoing build since 2022 that spans BigCommerce, Magento, Angular and .NET. Sixty percent of our work is engineers embedded in client teams, at $25 to $49 an hour. Our .NET and Angular engineers suit the integration side of a store, and ISO 27001 and SOC 2 Type II matter when they hold ERP and payment access. Reviewers score Quality 5.0; one asked for tighter internal coordination. If you want a BigCommerce-only boutique, we are the wrong call.

For BigCommerce-first stores

7. DigitlHaus Agency

DigitlHaus puts BigCommerce at 40 percent of its platform work, level with Shopify, and it has the strongest BigCommerce evidence here: five of its ten first-page reviews mention the platform. They describe store rebuilds and migrations for apparel, fabric, medical supply and fireworks retailers. It publishes $150 to $199 an hour with a $10,000 minimum, and 60 percent of its clients are mid-market. One client learned late that some pages would not be migrated without an extra fee, and Cost is its lowest sub-score at 4.7.

19. Always Open Commerce

Always Open Commerce, in Orlando, splits its services evenly across conversion optimisation, strategy, e-commerce, SEO and UX. Four of its ten first-page reviews mention BigCommerce and five describe migrations. It publishes $50 to $99 an hour with a $1,000 minimum, and 85 percent of its clients are small businesses. It scores 5.0 on Cost. One client missed that offshore work was part of the statement of work, and another found communication slow because the team works off US hours.

13. Optimum7

Optimum7 lists BigCommerce and Shopify at 30 percent each, and four of its ten first-page reviews mention BigCommerce, including a theme migration and a startup build. Its $1,000 minimum is among the lowest here, at $100 to $149 an hour. Its 4.6 rating across 29 reviews is the lowest on this list, and Cost scores 4.5. One client described a bad experience about 16 months after a migration was completed, and another found time-zone communication difficult.

17. Xumulus

Xumulus, in Chicago, puts BigCommerce at 50 percent of its platform work and Magento at 30, and its reviews lean on integration: Oracle and point-of-sale connections, a bundling extension, a digital asset system. Three first-page reviews mention BigCommerce. It scores 5.0 on Quality across 11 reviews, at $100 to $149 an hour. It has fewer than ten staff; one client said the project was understaffed early and took time to settle into a management routine.

16. IntuitSolutions

IntuitSolutions, in Philadelphia, puts BigCommerce at 60 percent of its platform work, the second-highest share here, with Shopify making up the rest. Both of its Clutch reviews mention BigCommerce: a medical e-commerce store and a redesign with SEO for a religious goods retailer. It publishes $150 to $199 an hour with a $10,000 minimum. Two reviews is too thin to judge delivery on, and Clutch shows no sub-scores, so the references matter more here than anywhere else on the list.

12. Flylight Media

Flylight Media is the only firm here that lists BigCommerce as 100 percent of its platform work. Its five reviews, however, describe websites and SEO for a seafood importer, a hotel brand and a research firm rather than stores. It publishes $150 to $199 an hour with a $25,000 minimum, and 75 percent of its clients are small businesses. It scores 5.0 on Quality, Cost and Willing to Refer. It has fewer than ten staff, and one client said it would benefit from more.

For B2B, ERP and integration-heavy builds

3. Trellis

Trellis ranks second on Clutch and is the ERP firm here: 15 percent of its services are ERP integration, across NetSuite, Infor and Microsoft Dynamics. BigCommerce and Shopify are 40 percent of its platform work each, and manufacturing is its largest industry. Reviews include an ERP-integrated site for a B2B wholesale distributor. It publishes $150 to $199 an hour with a $10,000 minimum. One client wanted a deeper understanding of order processing, and another better high-level status reporting.

2. Codup

Codup holds first place in Clutch’s BigCommerce ranking, with 75 reviews at 4.9, though BigCommerce is 20 percent of its platform work, behind Shopify and WooCommerce at 30 each. Its reviews describe custom e-commerce for businesses from a commercial tent maker to a fire truck company, and its most common project is under $10,000. It publishes $50 to $99 an hour. Clients asked for clearer cost packages, and one said a three-item scope addition nearly doubled the project budget.

5. Silk Software

Silk Software, in Irvine, splits its platform work between Magento at 60 percent and BigCommerce at 40, and ERP integration is 15 percent of its services, across Dynamics, SAP, NetSuite, Oracle and Infor. It publishes $100 to $149 an hour. It is Clutch-ranked 4th on a single review, a Magento store for a jewelry maker, which mentions SEO trouble along the way. One review is not enough to judge a 250-person firm, so treat references as essential.

8. DataArt

DataArt is the largest firm here, with 1,000 to 9,999 staff and a $100,000 minimum, the highest on the list. E-commerce is 10 percent of its services, with BigCommerce and Shopify at 45 percent of that each. Its first-page reviews describe B2B marketplace e-commerce, middleware and staff augmentation, but none names BigCommerce. It publishes $50 to $99 an hour. One client called it a bit expensive, and Cost is its lowest sub-score at 4.5.

For Magento-led agencies

4. Absolute Web

Absolute Web, founded in 1999, has 83 reviews at 4.9, the second-largest record here. Magento is half its platform work and BigCommerce 10 percent, and none of its first-page reviews names BigCommerce. Its reviews describe e-commerce builds and UX work for beauty, coffee and supplement brands. It publishes $100 to $149 an hour with a $10,000 minimum. One client found its marketing team less engaged than its developers.

9. Above The Fray

Above The Fray, in Portland, puts 80 percent of its platform work on Magento and 10 on BigCommerce. Its reviews describe stores for equipment manufacturers, a cable distributor and a cookware maker, often with SEO. It publishes $100 to $149 an hour with a $25,000 minimum. Quality is its lowest sub-score at 4.7. One client said the first site launched without pieces it needed to work, and another wanted more functional testing earlier.

10. Kadro Solutions

Kadro Solutions, in Raleigh, is 80 percent e-commerce, with Magento at 70 percent of its platform work and BigCommerce at 10. Five of its nine first-page reviews mention Magento; none mentions BigCommerce. Its $50,000 minimum is the second highest here, at $150 to $199 an hour. Schedule is its weak sub-score at 4.4. One client said account managers left without warning, and another that developers sometimes built from scratch where existing tools would have done.

14. Tekglide

Tekglide lists six e-commerce platforms, led by Magento at 30 percent and Shopify at 25, with BigCommerce at 10. It publishes $25 to $49 an hour, one of the two lowest bands here, with a $10,000 minimum, and scores 4.9 on Cost. Its reviews cover Magento and Shopify builds, SEO and staff augmentation. One client said prepaid hour buckets ran low without warning and working days were unclear; another wanted clearer instructions on data formats.

For Shopify, WooCommerce and marketing-led agencies

15. Canesta

Canesta scores 5.0 on Quality, Schedule and Willing to Refer across 19 reviews, and it is marketing-led: paid search and SEO are 30 percent of its services, and six of its ten first-page reviews involve SEO. Shopify is half its platform work and BigCommerce 20 percent. It publishes $50 to $99 an hour with a $5,000 minimum. It has fewer than ten staff, and one client asked for more written communication.

21. DYODE

DYODE, in Fullerton, is an e-commerce and paid media agency: advertising is 40 percent of its services. Shopify is 60 percent of its platform work, and four of its five reviews describe Shopify or Shopify Plus, including Shopify migrations. BigCommerce is 20 percent. It publishes $150 to $199 an hour and Cost is its lowest sub-score at 4.5. One client noted that agencies juggle many clients and struggle to stay up to speed on each.

18. Oyova

Oyova has 125 Clutch reviews, the most on this list, but it is a web agency first: custom software and web development are 45 percent of its services, and WooCommerce leads its platforms at 45 percent with BigCommerce at 10. None of its first-page reviews names BigCommerce. It publishes $150 to $199 an hour with a $5,000 minimum. Clients noted delays and the need for tighter alignment across overlapping projects.

20. Plan Left

Plan Left, in Nashville, is a web and SEO agency where e-commerce is 10 percent of its services, with WooCommerce leading its platforms at 40 percent and BigCommerce at 25. Its six reviews describe websites, branding and a mobile app, none on BigCommerce. It publishes $150 to $199 an hour with a $1,000 minimum. Its review summary notes it is adding support during clients’ peak hours.

For app and product teams

6. Mutual Mobile

Mutual Mobile, now part of Grid Dynamics, is a mobile firm: mobile apps are 35 percent of its services and e-commerce 10. It lists BigCommerce and Shopify at 50 percent each, but all ten first-page reviews describe apps and software, none a store. It publishes $150 to $199 an hour with a $25,000 minimum. Clients said it can over-promise on timelines and asked for more transparent quotes.

11. Trango Tech

Trango Tech lists twelve e-commerce platforms, with BigCommerce at 10 percent, but mobile apps are 40 percent of its services and all ten first-page reviews describe apps. It publishes $25 to $49 an hour. Its 4.7 rating is the second lowest here, with Schedule and Cost both at 4.5. One client said an app was months late and that they had to send legal letters before getting a reply.

What the twenty profiles show

BigCommerce specialists are the minority of the directory. Across all 762 firms, 68 name BigCommerce as their single leading platform, 205 lead with Shopify, 113 with Magento and 76 with WooCommerce. Another 248 list BigCommerce level with another platform. Of the 762, 659 also list Shopify and 307 put Shopify ahead of BigCommerce (Brain Station 23 analysis of Clutch, read 29 September 2026).

Focus is spread thin. The median firm puts 20 percent of its platform work on BigCommerce. Ninety firms put half or more on it, but 67 of those 90 have no client reviews and only 15 have three or more. In the top 20, the median share is 27.5 percent, six firms sit at 10 percent, and three lead with BigCommerce alone: Flylight Media, IntuitSolutions and Xumulus.

The reviews mention other platforms more often. We read the first page of reviews on each of the twenty profiles, 168 in all. Twenty-one mention BigCommerce, 28 Shopify and 25 Magento. Thirty describe a migration or replatforming and 34 involve SEO. The BigCommerce mentions come from seven firms; the other thirteen have none on their first page.

The firms are small, and Florida is overrepresented. Ten of the twenty have fewer than 50 staff, seven have 50 to 249 and three are larger. Five are headquartered in Florida. Six have fewer than ten reviews, while Oyova, Absolute Web and Codup have 75 or more each.

Cost is the weak sub-score. Of the 18 firms that show sub-scores, 13 score lowest, or joint lowest, on Cost. DataArt, Optimum7, Trango Tech and DYODE are lowest at 4.5. Magento is the largest platform for five of the twenty, which makes this Top 20 BigCommerce Development Companies in USA list partly a list of Magento agencies that also build on BigCommerce.

How to shortlist a BigCommerce development company

Order the filters so the first one removes the most firms.

Step 1: Name the job. A new store, a migration onto BigCommerce, an ERP integration and a headless rebuild need different firms. Start with the group above that matches.

Step 2: Check for BigCommerce evidence. Thirteen of the twenty have no BigCommerce mention in their first page of reviews. Ask each shortlisted firm for three live BigCommerce stores it built.

Step 3: Match your budget to the minimum. Minimums run from $1,000 to $100,000, and nine firms charge $150 to $199 an hour.

Step 4: Ask about the payment fee. A good vendor should know whether your gateways are embedded and what the Open Payment Provider Fee would cost you at next year’s sales.

Step 5: Ask about the integrations. Name your ERP, inventory and accounting systems, and ask how the sync handles API limits during peak trading.

Step 6: Ask who owns the accounts. The store, the payment contract, the apps and any hosting should be in your name from day one.

Step 7: Buy a paid discovery. A short fixed-fee phase that maps the catalogue, integrations and data migration shows the real size of the job before you fund it.

How to buy BigCommerce development: four engagement models

The engagement model decides who pays when the data migration turns out messier than the estimate assumed.

Fixed price moves overrun risk to the vendor, who prices it in. It suits a theme build or a small store with a settled catalogue. It fails on migrations and integrations, where old data surprises everyone.

Time and materials keeps the risk with you. It suits migrations, ERP work and headless builds. Cap each phase and review burn every week.

Support retainer covers app and theme updates, platform changes, small features, and monitoring of integrations. Watch prepaid hour buckets; one reviewer here ran out without warning.

Staff augmentation adds developers to your team. Codup, Tekglide, DataArt and Brain Station 23 publish staff augmentation work. It fails when nobody in-house owns the store’s roadmap.

The technical question: migrating onto BigCommerce, and Stencil or Catalyst

Thirty of the 168 first-page reviews describe a migration. The order of the work decides whether a replatform keeps its search traffic and its order history.

Step 1: Choose the plan and payment providers first. The plan sets your API limits and your payment fee, and both affect the build. Moving from an Open Payment Provider to an embedded one is cheapest before launch.

Step 2: Map the data. Products, variants, customers, order history, reviews and redirects. Decide what migrates and what is archived, in writing.

Step 3: Choose the storefront. Stencil themes are the conventional route and keep hosting inside BigCommerce. Catalyst is a Next.js storefront that suits stores wanting more front-end control, and it brings a separate hosting account, build pipeline and front-end skills (Catalyst).

Step 4: Build and test the integrations. ERP, inventory, tax, shipping and payments, each tested at peak volume against the plan’s API limits (BigCommerce Developer Center).

Step 5: Preserve search. Map every old URL to a new one with a 301 redirect before launch, and check the checkout end to end. A long or complicated checkout is cited by 17 percent of shoppers who abandon a cart (Baymard Institute).

The order matters because the plan and payment decisions change the integration design, and the integrations change what the storefront has to show.

Red flags: eight answers to walk away from

“We’ll set the store up under our account.” The store owner account should be yours, with the agency added as staff you can remove.

“The payment fee doesn’t matter.” It is 0.6 to 2.0 percent of eligible order value on self-service plans (BigCommerce). Ask for the number.

“We use our app licences.” Paid apps billed to the agency stop when the relationship does.

“We’ll migrate what we can.” Get the list of pages, data and redirects in writing. One reviewer here learned about excluded pages at the end.

“You’ll be fine on Growth.” The Growth cap is $100,000 in trailing-year sales, and plans upgrade automatically above it.

“We mostly do Shopify, but BigCommerce is similar.” Ask for three live BigCommerce stores.

“Scripts on checkout are fine.” PCI DSS now requires payment-page scripts to be authorized and monitored (PCI SSC).

“Our reviews speak for themselves.” Six firms here have fewer than ten, and thirteen have no BigCommerce review on their first page.

After launch: what the build quote leaves out

This part covers what owners wish they had settled before the final invoice, and what recurs for as long as the store trades.

What you must own before the final invoice

The BigCommerce store owner account, with billing in your name and the agency added as a staff user with only the permissions it needs.

The payment provider contracts, in your company’s name, so a change of agency does not interrupt payments.

Every app subscription, billed to you. Agency-wide licences stop the day the relationship does, and some apps hold data you need.

The theme or storefront code: the Stencil theme files, or for Catalyst the full repository with its commit history, plus the hosting account in your name.

The domain and DNS, and every API account and key, created by your store owner account so you can revoke them.

A runbook: how to deploy theme changes, restart an integration sync, restore data and roll back a release.

The bill that arrives after launch

A build quote covers the build. What recurs afterwards is usually larger over three years.

The plan fee rises with sales, because plans upgrade automatically at their caps, and Scale charges 0.9 percent on sales above $33,333 a month (BigCommerce). Add the Open Payment Provider Fee if your gateways are not embedded, app subscriptions, hosting for a headless storefront, integration maintenance, and change requests, which are usually the largest line by year two. Get the recurring number before you sign the build, and compare vendors over three years.

Security is a recurring cost

A store is a payment target, and the risk moves with every script you add.

Exploited software vulnerabilities started 31 percent of the breaches in Verizon’s 2026 report (Verizon DBIR 2026). On a hosted platform, the risk that stays with you is mostly what you add: apps, tags and scripts. Since 31 March 2025, PCI DSS requirements 6.4.3 and 11.6.1 have required scripts on payment pages to be authorized, checked for integrity and monitored for tampering (PCI SSC). Some merchants that meet the updated SAQ A criteria are no longer assessed on those two requirements (PCI SSC), so ask your provider which applies to you. Either way, write into the contract who inventories the scripts, who reviews new apps and how fast a critical fix is applied.

Accessibility is legal exposure

E-commerce is where accessibility lawsuits land. Of the 5,114 US digital accessibility lawsuits filed in 2025, 70 percent targeted e-commerce sites, and 45 percent of federal filings were against companies sued before (UsableNet). In 2026, 95.9 percent of the top million home pages had detectable WCAG failures (WebAIM). Name WCAG 2.2 AA in the contract rather than the word “accessible”, test the checkout with a keyboard and a screen reader, and treat overlay widgets with scepticism.

Contract clauses that surface in month nine

IP assignment on payment, not on final acceptance, covering the theme, any Catalyst code and custom apps.

Transition assistance: a set number of hours at an agreed rate to hand over to another agency.

Rate escalation caps for the support term, and notice before any change.

Subcontracting and offshore work, named in the statement of work. One reviewer here missed that offshore work was included.

Hour-bucket reporting, if you prepay support, with a warning when a bucket is nearly used.

Liability cap and insurance that reflect what a payment incident would cost.

Non-solicitation both ways, so neither side can hire the other’s key people during the contract.

This is not legal advice; have counsel review the contract.

How to leave without losing the store

Confirm you hold the store owner account, payment contracts, apps, code and domain. Trigger the transition hours while relations are still cordial. Export the theme and a full data backup. Record walkthroughs of the integrations. On the last day, remove the agency’s staff accounts and revoke every API account it created.

Hire in-house or hire a BigCommerce development company

The Bureau of Labor Statistics median for web developers was $92,650 in May 2025, and for software developers $135,980 (BLS). Glassdoor puts a BigCommerce developer at $82,619, before benefits (Glassdoor).

Hire in-house when the store changes every week and you run several integrations. One developer who knows your catalogue and ERP is worth more than an agency relearning them.

Hire an agency for a migration, a redesign or a headless build with an end date, where you need design, development and SEO for a few months.

Use staff augmentation when you have an e-commerce lead but not enough developers.

FAQ

Conclusion

The data behind this Top 20 BigCommerce Development Companies in USA list says three things. The platform’s pricing changed on 1 June 2026, so the payment providers and next year’s sales now belong in the brief. Most firms in the directory are multi-platform agencies, and thirteen of the top twenty have no BigCommerce review on their first page, so ask for live BigCommerce stores. And the specialists who lead with BigCommerce are small, which puts more weight on references.

Any of the twenty can build a store. What decides the next three years is whether the plan and payment fees were priced before launch, whether the integrations hold at peak, and whether the store account, payment contracts, apps and code are in your name on the day the agency leaves.
