More than 200 companies trust us.
Worked with BigCommerce agencies, technology partners, and commerce teams on a number of projects.
Why it gets harder to manage BigCommerce development as projects get bigger
BigCommerce lets teams work in different ways, but that makes it harder to deliver. As stores change, adding custom features, integrations, SEO, and performance improvements can make things more risky, even for capable teams.
- Changes to the custom storefront are getting bigger without a clear plan.
- SEO and performance were not taken into account until too late in development
- Integrations that add hidden dependencies
- Different vendors or internal teams not being on the same page
- Launch dates keep changing while work keeps getting harder.
Bad development isn't the main reason most BigCommerce projects fail. They fail because delivery becomes less organized as things get more complicated.
WHAT WE DO
BigCommerce Development Services
We offer focused BigCommerce development services that are built to stay stable, easy to maintain, and flexible as your business grows.
BigCommerce Implementation
Full BigCommerce implementation, including setting up the store, configuring it, integrating it, and getting it ready to launch. We make sure the platform is set up right from the start, so teams can grow without having to redo work or deal with operational issues.
BigCommerce App Development
Custom BigCommerce app development to extend the platform and support workflows that off-the-shelf apps cannot cover. Apps are built with clean architecture, predictable behavior, and long-term maintenance in mind.
BigCommerce B2B Store Development
The focus of BigCommerce B2B store development was on complicated pricing, customer groups, catalogs, and approval workflows. We help teams make B2B experiences that stay reliable as accounts, products, and rules change.
Headless Commerce Development
Using BigCommerce as the backend and modern frontend frameworks to build headless commerce. We make sure that backend APIs, frontend builds, and CMS layers all work together so that execution stays on track and releases stay under control.
BigCommerce Storefront Development
Custom development of BigCommerce storefronts that are optimized for speed, ease of use, and sales. Storefronts are built to support SEO, growth, and new features without slowing down delivery.
Enterprise BigCommerce Development Support
Help with big BigCommerce projects that have more than one store, integrations, and teams. We help keep architectural consistency, integration stability, and release readiness across builds that are hard to put together.
Our Process
How it Works
- 01
We know what your BigCommerce goals are, what you need for your storefront, what integrations you need, and what limitations you have. We make sure everyone agrees on the project's scope, assumptions, and success criteria so that everyone is on the same page from the start.
- 02
We set the rules for theme or storefront work, app development, headless architecture, and integrations. We plan out milestones, dependencies, environments, and testing so that everything stays in order.
- 03
We set up the BigCommerce storefront, theme, apps, or headless frontend and link them to the services they need. Integrations are set up with a steady flow of data and clear ways to deal with errors.
- 04
We check how storefronts work on different devices and during different user journeys. We check that the performance, core flows, and integration are all reliable. We make a clear checklist for the release.
- 05
We help with launching, rolling out, monitoring, and fixing things after they launch. After launch, we help make the storefront easier to use, faster, and easier to maintain as new needs arise.
CLEAR BIGCOMMERCE DEVELOPMENT
Clear visibility across every stage of BigCommerce development
As BigCommerce stores grow, changes to the storefront, integrations, and customizations can make things more complicated without anyone knowing. Clear visibility helps teams see how far they've come, what effects they've had, and what they need to do next at every stage of the development lifecycle.
Storefront progress clarity
You can see which storefront features, themes, and customizations are done, in progress, or waiting without having to rely on vague updates.
Integration impact awareness
Before problems come up, know how changes to integrations and APIs will affect how the store works, how quickly it releases new features, and how it behaves.
Alignment between teams
As the project moves forward, make sure that internal teams and clients are on the same page about priorities, timelines, and next steps.
Planning for a release with confidence
Plan releases based on how ready the real storefront is, what dependencies there are, and what limitations there are, not on last-minute fixes.
How We Hire
Choose the engagement model that works best for your BigCommerce development needs. You can choose from dedicated resources, fixed-scope projects, or flexible hourly support.
Dedicated developer
A full-time BigCommerce developer will work on your project and report to you one-on-one. They work according to your client's needs, giving them consistent support and deep knowledge of the platform.
Fixed-price model
A one-time contract with a set price, scope, deadlines, and budget. Best for BigCommerce projects with clear goals, milestone-based payments, and costs that can be predicted.
Hourly engagement
You only pay for the work that is done each hour with this rolling contract. Great for ongoing BigCommerce support, maintenance, and flexible development, with billing every week or month.
WHAT WE DO FOR BUSINESS
BigCommerce experience across industries
We've made BigCommerce stores for businesses that sell to other businesses (B2B) and businesses that sell to consumers (B2C) in a variety of fields. Each store has its own catalog structure, pricing model, and integration needs.
Why teams trust Northstar for BigCommerce Development
When BigCommerce projects are really complicated, teams choose us. We try to make technical choices clear, changes easy to see, and progress easy to see as stores grow.
Delivery
BigCommerce work is planned with clear scope and ownership, so changes to the storefront, integrations, and releases can happen without having to do them over and over again or follow up.
Execution
Day-to-day BigCommerce development is closely monitored so that problems are found early and progress stays on track as things get more complicated.
Visibility
Teams always know what is in progress, what is at risk, and what comes next across BigCommerce builds - reducing surprises as release dates approach.
Experience with BigCommerce across different implementations
Experience gained from building storefronts, integrating them, adding features, and working on platforms for a long time.

BigCommerce add-ons
Add-ons made just for BigCommerce that fill in common gaps without needing a lot of custom development.
Ordering a lot of products
Let customers order a lot of items at once by using SKUs or structured order forms. Prices are automatically figured out based on the number of items, the type of customer, or the rules for pricing.
App for Scanning Barcodes (POS)
Use your device's camera to scan product barcodes to quickly search for, view, or add items to your cart. Made to help customers and store workers find products and place orders faster.
Editing Many Products at Once
You can change prices, inventory, categories, attributes, and custom fields all at once. Made for big catalogs where teams can't work as quickly when they have to manage each item separately.
Search by year, make, and model
Add structured filtering by year, make, and model to BigCommerce stores. Great for catalogs of cars, parts, and other things that need to be compatible and have accurate product matching.
