What to Know About BigCommerce Development & Design Before You Choose a Partner
Summary
- BigCommerce is an open SaaS ecommerce platform built on the Stencil framework, supporting B2B and B2C stores of all sizes.
- Top BigCommerce development and design services include custom theme design, platform migrations, system integrations, B2B features, and performance work.
- Certified BigCommerce partners (Elite, BigDev, B2B Certified) have a proven track record of implementations and measurable ROI.
- Businesses using BigCommerce B2B Edition have reported up to 391% three-year ROI.
- Choosing the right agency depends on certifications, integration experience, and post-launch support capability.
BigCommerce Development & Design covers everything from building a custom storefront to connecting your store with ERPs, CRMs, and PIM systems — and picking the right team to do it makes a real difference in outcomes.
If you're looking for a quick comparison, here are the five main service categories to evaluate:
- Custom theme design - bespoke layouts built on BigCommerce's Cornerstone base, aligned to your brand
- Platform migrations - moving product data, customer records, and order history from platforms like Shopify, Magento, or WooCommerce
- System and API integrations - connecting ERP, CRM, PIM, and POS systems for accurate, automated operations
- B2B development - custom pricing rules, quote generation, and customer segmentation down to the SKU level
- Performance and SEO - site speed, Core Web Vitals, organic traffic, and conversion work
The platform itself is well-regarded. BigCommerce is the #1 ranked B2B platform in Paradigm's 2025 Mid-Market Report, and real-world implementations have shown results like 211% ROI in under eight months and over $700,000 in cost savings from retiring legacy systems. But those results come from good execution — not the platform alone.
That's where agency selection matters. Not every development shop has the same depth of experience with BigCommerce's API-first architecture, headless builds, or complex B2B configurations. Certifications like Elite Partner status and BigDev Certification are a useful filter — they require passing rigorous technical assessments and meeting client satisfaction benchmarks.
I'm Steve Pogson, founder of First Pier and a certified ecommerce specialist with over two decades of hands-on experience in BigCommerce Development & Design and ecommerce growth strategy. In this guide, I will explain the five service categories worth comparing so you can choose the right path for your business.
Understanding BigCommerce Development & Design
BigCommerce is an "Open SaaS" platform, which means it provides the security and hosting of a Software-as-a-Service model but offers the flexibility usually found in open-source systems. For a business here at First Pier in Portland, ME, this means you don't have to worry about server maintenance or security patches, yet you still have the freedom to build a completely custom storefront.
The platform uses the Stencil framework for its themes, which allows developers to create fast, responsive, and SEO-friendly sites. One of the standout features I often discuss with clients is the Multi-Storefront (MSF) capability. This allows you to manage multiple brands, regions, or customer segments from a single BigCommerce dashboard. It’s an efficient way to scale without the headache of logging into five different backends.
Because BigCommerce is Commerce built for momentum, it is designed for businesses that plan to grow. Its API-first architecture means that almost every part of the store—from the checkout to the product catalog—can be accessed and modified via code.
Core Features of BigCommerce Development & Design
When we look at the technical side of BigCommerce Development & Design, the Storefront API and GraphQL are the stars of the show. These tools allow us to pull data into custom frontends, which is essential for headless commerce. Headless setups separate the "head" (the part the customer sees) from the "body" (the backend engine), giving you total control over the user experience.
Other core features include:
- Checkout Customization: Unlike some platforms that lock down the checkout page, BigCommerce allows developers to use the Checkout SDK to create a branded, smooth payment experience.
- Mobile Responsiveness: Every site we build must work perfectly on phones. BigCommerce themes are built mobile-first to ensure high conversion rates across all devices.
- Advanced Search: Built-in filtering and search tools help customers find products faster, which directly impacts your bottom line.
Comparing the Top 5 BigCommerce Service Categories
Choosing a service provider isn't just about finding someone who can write code. It’s about finding a team that understands the business logic behind your store. Research shows that companies using the BigCommerce B2B Edition see a 391% three-year ROI. To get those kinds of numbers, you need to focus on specific service categories.
Good ecommerce UX design is the foundation of every successful project. Whether you are building custom components or setting up complex data pathways through Feedonomics, the goal is always to make the shopping journey as easy as possible.
1. Custom Theme Design and Brand Identity
Many businesses start with the "Cornerstone" theme, which is the BigCommerce standard. While it’s a solid base, a growing brand usually needs more. Custom theme design ensures your site doesn't look like a template.
We focus on branding identity to make sure the colors, typography, and layouts match your brand's voice. A bespoke layout isn't just about aesthetics; it's about shopper satisfaction. By creating unique UI components, we can highlight your best-selling products and guide users toward the "Add to Cart" button more effectively.
2. Platform Migrations and Data Transfer
One of the biggest fears for any business owner is losing data during a move. When we handle platform migrations, our priority is zero data loss. This includes:
- Catalog Transfer: Moving thousands of SKUs, including variants, images, and descriptions.
- Customer Records: Ensuring your loyal customers can still log in and see their history.
- Order History: Keeping your past sales data for accounting and customer service.
- SEO Preservation: This is critical. We use 301 redirects to make sure your old links don't lead to "404 Not Found" pages, which protects your search engine rankings.
3. Advanced System and API Integrations
A high-performance store shouldn't be an island. It needs to talk to your other business tools. We specialize in connecting BigCommerce to:
- ERP Systems: Automate your back-office by syncing orders and inventory with ERP services.
- CRM Sync: Keep your customer data updated in tools like Salesforce or HubSpot.
- PIM Management: Use a Product Information Management system to handle complex catalogs across multiple channels.
- POS Connectivity: Connect your physical retail location in Portland to your online store for a unified inventory view.
Using tools like Feedonomics, we create automated workflows that ensure your product data is accurate across Google Shopping, Amazon, and your own storefront.
4. B2B Development and Wholesale Features
BigCommerce is a leader in B2B ecommerce. It handles complex needs that would break other platforms. If you run a wholesale business, you likely need a wholesale strategy that includes:
- Custom Pricing: Show different prices to different customer groups.
- Quote Generation: Allow customers to request a quote directly from the cart.
- Customer Segmentation: Group buyers by industry, size, or region.
- SKU-Level Rules: Set minimum order quantities or bulk discounts for specific items.
According to the Paradigm Mid-Market Report, BigCommerce is the top choice for these features because it offers them natively, reducing the need for expensive custom builds.
5. Performance and BigCommerce Development & Design
Speed is a feature. If your site takes more than three seconds to load, you are losing money. We use the BigCommerce Developer Center resources to stay on top of the latest performance standards.
Our work in BigCommerce SEO focuses on Core Web Vitals—the metrics Google uses to measure user experience. By improving site speed and mobile performance, we help drive organic traffic and conversion growth. We also set up advanced analytics so you can see exactly where your customers are coming from and what they are buying.
The BigCommerce Development Process from Discovery to Launch
I believe that a project is only as good as its plan. Our process starts with a discovery phase. We do a technology audit of your current setup and hold stakeholder workshops to understand your goals.
Next, we move into wireframing and prototyping. This allows you to see the "skeleton" of the site before we write a single line of code. We also use ecommerce data analytics to inform our design decisions.
Before launch, we run rigorous QA testing and user acceptance testing. We don't just check if the buttons work; we make sure the entire system—from the ERP sync to the email notifications—is perfect. After launch, we provide ongoing support to keep the site running smoothly.
Technical Frameworks and Programming Languages
The BigCommerce stack is modern and flexible. While the backend handles the heavy lifting, we use CSS, HTML, and Javascript to craft the frontend. For more advanced projects, we use React and Next.js.
BigCommerce recently introduced "Catalyst," a developer-first framework that uses the GraphQL Storefront API and the BigDesign library. This allows us to build incredibly fast, headless storefronts. Even though we often use Shopify automation for other projects, we find that BigCommerce's open API offers a unique level of control for complex integrations.
Why Ongoing Support and Maintenance are Essential
Launching your store is just the beginning. The digital world moves fast, and your site needs to keep up. Ongoing support includes security updates, performance audits, and feature refinements.
We also help with shipping management to make sure your logistics are as efficient as your storefront. Whether it’s 24/7 monitoring to prevent downtime or regular training sessions for your team, we stay involved to ensure your technology never becomes a bottleneck.
Frequently Asked Questions about BigCommerce
How does BigCommerce compare to other platforms like Shopify?
BigCommerce often provides more built-in features right out of the box, such as advanced product filtering and multi-currency support. Importantly, BigCommerce does not charge per-transaction fees, which can save high-volume merchants a significant amount of money compared to Shopify. However, Shopify has a larger app ecosystem, so the choice often depends on whether you prefer built-in power or third-party flexibility.
Is BigCommerce a good choice for B2B businesses?
Yes, it is arguably the best SaaS choice for B2B. The BigCommerce B2B Edition offers specific tools for custom pricing, quotes, and corporate account management that outperform many standard e-commerce platforms. It allows you to manage B2B and B2C customers on the same platform without needing separate stores.
What should I look for in a BigCommerce development agency?
Look for certifications such as Elite Partner status or BigDev Certification. These aren't just badges; they indicate that the agency has passed rigorous technical bootcamps and has a track record of successful, high-GMV implementations. You should also ask for case studies that show a clear ROI, like the 211% ROI seen in some top-tier projects.
To Sum Up
BigCommerce provides a stable foundation for brands that need to scale without the limitations of traditional software. Success on the platform depends on clean code, thoughtful design, and deep system integrations. Here at First Pier, we help businesses navigate these technical requirements to build stores that perform. Whether you are moving from a legacy system or building a headless storefront, working with an experienced team ensures your technology supports your sales goals. More info about our services
