Our BigCommerce development services
Choose one service or combine several into one build. Each starts from a task your buyers or team need done.
Theme and storefront development
Custom Stencil themes, menus and templates. We start with native settings and Page Builder, then code what is missing.
App selection and custom apps
We check marketplace apps for fit, cost and support, and develop a custom app when none of them fits.
API integrations
ERP, PIM, warehouse and CRM connections with clear rules on which system owns prices, stock and orders.
Catalog and product data
Supplier and product data cleaned, checked and imported in bulk, with problem records held back until they are fixed.
Headless and Catalyst storefronts
We check whether a headless Catalyst storefront is worth running, and prove cart, login and checkout before you commit.
Migration, launch and handover
We move products, customers, orders, content and URLs after a test run, set up redirects and hand over a working store.
BigCommerce development
use cases
BigCommerce suits growing brands and B2B sellers who want a SaaS platform but need a custom storefront and solid integrations.
Typical situations where our BigCommerce team delivers the most value:
-
Launching on BigCommerce
You are opening a new store or brand and need a fast, branded storefront with the right apps from the start.
-
Moving to BigCommerce
You are migrating from Magento, Shopify or another platform and need products, customers, orders and URLs moved safely.
-
A custom theme and storefront
A standard theme no longer fits your brand, catalog or checkout, and you need a custom design built for your buyers.
-
ERP, PIM and CRM integrations
Prices, stock, orders and customer data must flow automatically between BigCommerce and the systems that run your business.
-
B2B on BigCommerce
Trade buyers need customer groups, price lists, quotes and bulk ordering on top of your retail store.
-
Large catalog updates
Thousands of products need new categories, attributes or descriptions, faster than your team can update them by hand.

Accountable engineering

We analyze the business and technical context, identify the real bottleneck, challenge weak assumptions when needed, and take responsibility for the technical outcome.
-
03
Senior expertise for CTO-led execution
We support technical leaders with experienced engineers, architecture expertise, and practical roadmap execution.
This helps CTOs and Fractional CTOs stay strategic while having a reliable team to execute.
-
04
Curated teams, not generic outstaffing
Every dedicated team is built around the client’s actual requirements, workflow, culture, risks, and delivery context.
We assess technical skills, soft skills, project fit, culture fit, communication style, and risk factors before proposing engineers.
-
05
Practical AI, from the process
We start from the business process, compare platform features, ordinary automation and AI, and use AI only where it removes real work.
Every AI step gets quality checks and human oversight.
-
06
A partner that has your back
Good delivery depends on trust, honest communication, and people who care about the outcome.
We stay close to the problem, speak openly, involve the right experts, and do not leave clients alone with delivery risk.

Frequently asked questions
Theme and storefront development, app selection and custom apps, ERP, PIM and CRM integrations, catalog data work, headless assessment, and migration to BigCommerce with launch and handover.
Start with the simplest option that works. Native settings and Page Builder come first, then theme changes, then a proven app. Custom code covers only what those cannot do.
Only if you need an experience your theme cannot deliver. Catalyst is BigCommerce’s Next.js headless framework. A separate frontend means more upkeep, so we prove cart, login and checkout before you commit.
For each data flow, we agree which system owns prices, stock, customers and orders. Bulk syncs use queues and retries within your API limits, and we check the results in your store.
Yes. We move products, variants, customers, orders, content and URLs, run a test migration first and set up redirects to protect search traffic. Our BigCommerce migration services cover the full move.
It depends on customization, apps, integrations, catalog size and migration. We quote the build separately from licenses and app fees. Our published BigCommerce catalog project took three months.
