BigCommerce Theme Architecture
Templates That Don't Fight Your Merch Team
Most BigCommerce theme work fails one of two ways — a stock Cornerstone build that can't express the brand, or a custom fork that locks merchandising out of Page Builder. We build the third path: bespoke Stencil templates with Page Builder regions, Widget Builder components, and metafield-driven content blocks your team can compose without filing a ticket. Pair with senior BigCommerce design, BigCommerce development, and BigCommerce SEO from one Elite Partner team.
Four Ways We Ship Templates
Pick the Engagement That Fits the Brief
Custom Stencil Theme Build
Cornerstone-based or ground-up Stencil theme. Handlebars partials, SCSS tokens, Page Builder regions, metafield-driven content, and Widget Builder components — engineered for your catalog depth, merchandising flow, and brand system.
Cornerstone Customization
Keep the upgrade path. We customize Cornerstone via child-theme overrides, custom widgets, and Page Builder layouts — so you get a tailored storefront without forking off the BigCommerce-maintained base.
Curated Template Adoption
Pick a Stencil marketplace theme that genuinely fits your catalog, then tune it. Faster than a custom build, cleaner than a fork — typesetting, PDP / PLP density, faceted nav, and checkout polish dialed to your brand.
Catalyst Headless Storefront
BigCommerce's React framework — Next.js + Makeswift visual editing on top of the GraphQL Storefront API. The right call when Stencil's theme architecture caps your UX, Core Web Vitals targets, or multi-channel ambitions.
Custom vs. Curated vs. Catalyst
A Short Decision Tree
Match the signal on the left to the route on the right. If two rows describe you, the simpler route almost always wins.
You're on a stock Cornerstone theme and outgrowing it visually, but merchandising is happy.
›Cornerstone customization — keep upgrades, layer custom widgets and Page Builder regions.
Catalog depth, B2B price lists, or Multi-Storefront branding push beyond a marketplace theme.
›Custom Stencil theme build — own the templates, ship metafield-driven content systems.
Page Builder content velocity matters more than novel layouts; team wants to iterate without devs.
›Curated template + Page Builder layout library — fastest path to a polished, editable storefront.
Core Web Vitals targets, headless CMS, mobile-app parity, or composable commerce on the roadmap.
›Catalyst (Next.js + Makeswift) headless — only if Stencil genuinely caps the experience.
What You Get
Standard Template Deliverables
Every engagement ships a documented theme, an editor handoff, and a component library merchandising can use. We don't hand off a tarball and disappear.
- Stencil child theme on Cornerstone with documented overrides
- Page Builder layouts for home, PLP, PDP, cart, content pages
- Widget Builder custom widgets (hero, lookbook, USP bars, comparison, social proof)
- Metafield-driven content blocks (PDP, PLP, brand pages)
- Faceted navigation and PLP density tuning
- PDP variant, swatch, and option logic
- Cart drawer and accelerated payment surfacing
- Theme typography, color, spacing tokens documented
- Accessibility pass (WCAG 2.2 AA)
- Core Web Vitals budget (LCP, INP, CLS)
- Theme certification submission (where applicable)
- Editor handoff doc and component library
Catalyst Headless
When to Go Headless With Catalyst
Catalyst pairs Next.js, React, and Makeswift visual editing on top of BigCommerce's GraphQL Storefront API. It's the right call when traditional Stencil caps your UX, you need headless CMS integration (Contentful, Sanity, Storyblok), Core Web Vitals targets demand edge-rendered React, or you're running multi-channel (web + mobile app + kiosk) from one commerce backend. It's the wrong call when Stencil + Cornerstone + Page Builder would've solved the same problem in a third of the time. We've talked clients out of Catalyst when the ROI wasn't there.
BigCommerce Templates — Quick Answers
Custom Stencil theme or curated marketplace template — which is right for us?
Curated wins when your catalog and brand fit a Stencil marketplace theme cleanly and Page Builder gives merchandising enough control. Custom wins when you need bespoke templates, deep metafield-driven content, distinct PDP/PLP density, Multi-Storefront branding, or B2B Edition wholesale UX that a stock theme can't cover. We scope both honestly on the first call — fork-and-pray is the worst outcome.
What's the difference between Stencil + Cornerstone and Catalyst?
Stencil is BigCommerce's traditional theme framework — Handlebars templates, SCSS, JS, Page Builder regions, served from BigCommerce's hosted CDN. Cornerstone is the official open-source Stencil reference theme. Catalyst is the newer React-based headless framework — Next.js + Makeswift on top of the GraphQL Storefront API, deployed on Vercel or similar. Most merchants stay on Stencil. Catalyst is the right call when you need maximum UX flexibility, headless CMS, multi-channel reach, or Core Web Vitals that Stencil can't deliver.
Can we keep using Page Builder if you build a custom template?
Yes. Every custom Stencil theme we build is Page Builder-aware — region zones on home, PLP, PDP, and content templates, plus custom Widget Builder components your merch team can drop into any zone. The point of a custom theme isn't to lock out merchandising; it's to give them better building blocks.

BigCommerce Template FAQ
Do you build for BigCommerce Multi-Storefront?
Yes. We architect template systems for Multi-Storefront — shared component library, channel-aware content, regional checkout, and brand-distinct theming across storefronts. One codebase, controlled variance, centralized merch.
Will a custom theme break Page Builder for our merchandisers?
No — that's the failure mode of forking Cornerstone without discipline. Every custom build we ship preserves Page Builder regions and adds Widget Builder components on top, so merchandisers can compose home, PLP, PDP, and content pages without engineering.
How does the BigCommerce theme certification process work?
Themes intended for the BigCommerce marketplace go through a structured review — code quality, performance, accessibility, browser support, and design polish. For client-only themes we apply the same standards even though certification isn't required, because it produces themes that hold up under real catalog scale.
Can you migrate our theme when we upgrade BigCommerce or move to Catalyst?
Yes. We handle Stencil v2 → v3 era migrations, Cornerstone version upgrades, and Stencil → Catalyst replatforms with template parity, redirect mapping, schema preservation, and merchandising continuity. Replatforming is a tool, not a default — we scope it honestly.
What does a custom BigCommerce template engagement cost?
Engagements start at $185/hour with fixed-fee scopes for defined builds and milestone-based pricing for full custom themes. Cornerstone customizations are typically the lightest scope; Catalyst headless builds are the heaviest. You'll see a pricing band on the first strategy call.
Do you handle B2B Edition theming?
Yes. B2B Edition introduces buyer portals, company hierarchies, Price Lists, quote management, and gated catalogs — all of which need template treatment. We theme the buyer experience end-to-end, not just the public storefront.
