Why Hire

Why Hire a BigCommerce Developer for Custom Work?

Platform specifics matter. A BigCommerce developer builds on Stencil + Cornerstone correctly, avoids theme bloat, integrates apps and ERPs cleanly via the V3 REST API and GraphQL Storefront API, and ships features that respect SEO. We design catalogs, navigation, and templates for scale, implement robust permissions and Multi-Storefront architecture, and wire the ERP / OMS / CRM / PIM integrations your operations rely on — without bloating the stack. We build on both traditional Stencil and fully-headless Catalyst (Next.js + Makeswift). Outcome: consistent Core Web Vitals, fewer regressions, and cleaner paths to checkout.

What We Build

What Does a BigCommerce Developer Handle Day to Day?

Information architecture, theme development on Stencil + Cornerstone (Handlebars, SCSS, JS), Catalyst headless storefronts (React + Next.js + Makeswift), BigCommerce-only features (Widget Builder, Checkout SDK / Open Checkout, Multi-Storefront, B2B Edition, Page Builder), custom private and public apps, deep API integrations (V3 REST Admin API, GraphQL Storefront API, webhooks), feed connections, subscription flows, internationalization, and workflow automation — paired with Core Web Vitals (LCP, INP, CLS) performance hardening, accessibility (WCAG 2.2 AA), and technical hygiene (routing, canonicals, schema, redirects, llms.txt) so growth doesn't break UX or rankings.

BigCommerce Developer — Quick Answers

What is 1Digital® as a BigCommerce developer?
1Digital® Agency is a BigCommerce Elite Partner and BigDev Certified agency founded in 2012, with 50+ specialists including Stencil developers, Catalyst (Next.js + React) engineers, BigCommerce app developers, and SEO / PPC / lifecycle marketers. Trusted by 400+ brands with a 4.9/5 rating across 941+ verified reviews. We build across traditional Stencil + Cornerstone (Handlebars), Catalyst headless (Next.js + Makeswift), Widget Builder, Checkout SDK / Open Checkout, GraphQL Storefront API, V3 REST API, B2B Edition, Multi-Storefront, and international expansion.
Where do we start?
Audit theme, apps, Core Web Vitals, and integrations (ERP, OMS, CRM, PIM, WMS); map UX, product data (metafields, custom fields, channel-aware catalogs), and URL architecture; scope Multi-Storefront or B2B Edition requirements; define sprints with redirect mapping and migration QA where relevant.
Common BigCommerce deliverables?
Custom Stencil + Cornerstone themes or Catalyst (Next.js + Makeswift) headless storefronts, Widget Builder custom widgets, Checkout SDK customizations, server-side API logic via the V3 REST API, Page Builder content systems, app integrations (Klaviyo, Recharge, Yotpo, Smile.io, Searchspring, Klevu, Algolia, Rebuy, Nosto), ERP / OMS / CRM / PIM connectors, Storefront / Admin GraphQL API work, schema graphs, llms.txt, and 301 redirect maps.
How do we improve performance?
Audit and prune app footprint, lazy-load media, compress and serve next-gen images (WebP, AVIF), defer non-critical JS, optimize Handlebars partials and faceted-search queries, leverage BigCommerce's CDN (or Vercel / Netlify edge hosting for Catalyst headless) — targeting LCP under 2.5s, INP under 200ms, CLS under 0.1.
Stencil + Cornerstone or Catalyst headless — which is right?
Stencil + Cornerstone (Handlebars) is right for most BigCommerce merchants — faster to build, easier for merchandising teams to iterate via Page Builder, and well-supported by BigCommerce's ecosystem of apps. Catalyst (Next.js + React + Makeswift) makes sense when you need maximum UX flexibility, multi-channel reach, headless CMS integration (Contentful, Sanity, Storyblok), Core Web Vitals performance traditional theme architecture can't deliver, or MACH composable commerce patterns. We scope the trade-offs honestly — headless isn't right for every brand, and Stencil isn't automatically wrong just because you've outgrown a stock theme.

BigCommerce Web Developers FAQ

Why choose 1Digital® Agency for BigCommerce development?
Partnering with 1Digital® Agency means working with a BigCommerce Elite Partner and BigDev Certified agency with 15 years of eCommerce specialization. Our 50+ in-house specialists include Stencil developers, Catalyst (Next.js + React) engineers, and BigCommerce app developers — delivering bespoke solutions from Stencil + Cornerstone themes to fully-headless Catalyst, Multi-Storefront architecture, B2B Edition rollouts, and complex enterprise integrations.
What makes 1Digital® stand out as a top BigCommerce development agency?
Our reputation as a leading BigCommerce Elite Partner comes from 15 years of specialization, purpose-built solutions across the full BigCommerce ecosystem (Stencil, Catalyst, Widget Builder, Checkout SDK, Multi-Storefront, B2B Edition, Page Builder), and a client-focused approach that supports high-performance BigCommerce stores at every tier of complexity.
How do our BigCommerce development services enhance your site's functionality?
Our developers use BigCommerce-native architecture patterns, advanced theme customization (Stencil sections, Cornerstone overrides, Page Builder widgets, metafields, custom fields), Checkout SDK extensions, Widget Builder components, and Catalyst headless where warranted — elevating speed, usability, and enterprise functionality without sacrificing maintainability.
What unique benefits do our BigCommerce SEO services offer?
Our BigCommerce SEO services optimize site structure, content, internal linking across Multi-Storefront setups, schema graphs (Product, Review, AggregateRating, Organization, FAQPage), llms.txt, and entity clarity — strengthening visibility across Google, ChatGPT Shopping, Perplexity Shop, Google AI Overviews, Gemini, and Amazon Rufus.
How does 1Digital® ensure sustained success for your BigCommerce site post-launch?
Ongoing support, performance tuning (Core Web Vitals — LCP, INP, CLS), app maintenance, BigCommerce platform updates, automation iteration, and strategic enhancements — so your store continues to grow and adapt to changing market demands and BigCommerce ecosystem evolution.
When does it make sense to upgrade to BigCommerce Enterprise?
Enterprise becomes compelling once you approach $1M+ GMV, need Multi-Storefront / multi-region architecture, want priority support, require native B2B Edition wholesale, or need dedicated launch engineer and merchant success support. We scope honestly — Enterprise isn't automatically the right tier for every merchant, and we've talked brands out of upgrading when the ROI wasn't there yet.
Do you build on BigCommerce Catalyst (headless)?
Yes. Catalyst is BigCommerce's React-based storefront framework built on Next.js, paired with Makeswift visual editing. We build fully-headless Catalyst storefronts when traditional Stencil theme architecture can't deliver the UX flexibility, multi-channel reach, or Core Web Vitals performance required. Catalyst is our default headless recommendation on BigCommerce, but we scope trade-offs honestly — Stencil + Cornerstone is often the smarter call.
How can I hire BigCommerce developers or engage a BigCommerce development agency?
Start by defining project requirements (migration to BigCommerce, redesign, Multi-Storefront expansion, B2B Edition launch, Catalyst headless, custom app), then evaluate agencies based on BigCommerce Elite Partner status, BigDev certification, case studies, team size, and communication. With 1Digital® Agency, you gain a BigCommerce Elite Partner development team experienced in delivering scalable, high-performing stores across every tier of complexity.
Can we migrate your existing eCommerce platform to BigCommerce?
Yes. Our migration experts ensure smooth transitions from any platform to BigCommerce — Shopify, Magento (Adobe Commerce), WooCommerce, Volusion, Salesforce Commerce Cloud, NetSuite SuiteCommerce, custom platforms — with SEO-safe URL mapping, 301 redirect deployment, schema graph preservation, data integrity QA, and minimal operational disruption. We also handle BigCommerce v2 → v3 migrations.
How do we ensure new features perform optimally during a BigCommerce redesign?
Structured redesign process — UX mapping, staging builds, schema graph preservation, 301 redirect mapping, regression testing across devices, accessibility QA (WCAG 2.2 AA), and Core Web Vitals validation — ensuring every feature functions correctly and that changes don't disrupt rankings, conversion flows, or core site behavior.
What distinguishes 1Digital® Agency from other BigCommerce development services?
As a BigCommerce Elite Partner with 15 years of development experience, we bring reliable support, scalable solutions across Stencil and Catalyst, and refined processes. The team that develops can also handle design, SEO, PPC, and lifecycle — so you're not coordinating multiple vendors across your BigCommerce program.
How do our BigCommerce designs boost your marketing efforts?
Our BigCommerce development and design incorporate SEO-friendly layouts, schema graphs, llms.txt, structured content, and conversion-focused elements — strengthening engagement, paid ROAS, AI-engine citation share, and customer retention across lifecycle channels.
Do you handle BigCommerce B2B Edition and native wholesale?
Yes. We build on native BigCommerce B2B Edition — customer accounts, company-based pricing, Price Lists, Customer Groups, net payment terms, buyer-specific catalogs, quote management, and wholesale portal customizations. No third-party wholesale app required. We can also support B2B-specific SEO including wholesale catalog indexation, customer-group-aware content, and buyer-intent keyword targeting.
Can you build Multi-Storefront / channel architectures?
Yes. BigCommerce Multi-Storefront supports multiple branded storefronts from a single back office. We architect Multi-Storefront setups for regional markets, sub-brands, B2B / DTC separation, or dedicated wholesale channels — with shared catalogs, channel-aware product visibility, separate branded checkout, centralized reporting, and a unified back-office workflow.
Do you handle BigCommerce v2 → v3 migrations?
Yes. Our BigCommerce developers manage v2 → v3 API migrations with product option updates, modifier conversions, API endpoint adjustments, and storefront changes. We deliver clean cut-overs with redirect mapping, schema preservation, and full regression testing across PDP, PLP, cart, and checkout flows.
