[ What you get ]

4 deliverables. Nothing implicit.

Storefront build: A Catalyst or Stencil storefront assembled against the catalog architecture.You own: The storefront source in your repository
Catalog architecture: Categories, rules, and complex product structures designed before build.You own: A documented catalog and pricing architecture
B2B features: Company accounts, price lists, and quote flows configured where the model needs them.You own: A working B2B setup with role documentation
Integrations: ERP, PIM, and marketing services connected with data flows documented.You own: Working integrations with their contracts documented
Done means: Done means test orders complete across retail and B2B price lists, the storefront deploys from your repository, and every integration's data flow is written down.
Not included: BigCommerce plan fees and third-party services are yours; merchandising operations stay with your team.

[ How it works ]

The bigcommerce development engagement, phase by phase.

Discover & scope: We map how bigcommerce development fits into your current stack, then agree a written scope with the acceptance criteria attached before work begins.
Plan & architect: The implementation plan records the structure, boundaries, and integration points, so build decisions are documented rather than improvised.
Build & integrate: Implementation covers storefront build and catalog architecture in reviewable increments against the agreed plan.
Verify & hand over: We verify the acceptance checks, close the engagement out with integrations, and hand over documentation your team can operate without us.

[ Field notes ]

How we think about bigcommerce development.

Why BigCommerce for flexible catalog control: BigCommerce pairs a hosted platform with deep catalog controls for brands selling at scale. The Stencil theme engine gives developers direct control over storefront output while merchant tools keep operations connected.
Who this work is for: This is for brands that need flexible catalog controls, B2B capability, and connected commerce operations. Teams managing variants, categories, and pricing at scale benefit from a deliberate catalog architecture.
Deliverables on every engagement: Deliverables cover a storefront build, catalog architecture, B2B features, and integrations. Each item maps to the Stencil or API surface so work is verifiable at launch.
Discovery: catalog architecture & B2B needs: Discovery maps products, variants, categories, and brands into a catalog architecture that fits the merchant's operating model. B2B needs are scoped early because they shape pricing and company structure.
Stencil themes & the Cornerstone reference: BigCommerce storefronts are built on the Stencil theme engine with Handlebars.js, YAML front matter, and Sass/SCSS through the Citadel framework. The Cornerstone reference theme and Page Builder give a working baseline for custom work. The Stencil CLI handles theme development and validation so changes stay consistent across the theme's file structure.
Storefront API & Checkout SDK: The GraphQL Storefront API and REST APIs expose catalog, cart, and checkout data for the storefront. BigCommerce Catalyst provides a current Next.js/React headless reference, while Open Checkout is treated as an open-source reference implementation rather than a promise of unlimited checkout control. Storefront token usage is checked against the current private-token requirements before server-to-server work is approved.
Catalog architecture & B2B capability: Catalog architecture structures products, variants, categories, and brands for flexible merchandising. B2B capability adds company-level catalog and pricing rules that operate independently of retail pricing.
Integrations & connected operations: Integrations connect BigCommerce to the merchant's broader commerce operations through REST and GraphQL APIs. Connected operations keep orders, inventory, and customer data flowing between systems.
Quality, performance & multi-storefront: Quality checks run through the Stencil CLI, which validates theme assets before deployment. Merchant tools and multi-storefront support let one platform serve multiple storefront experiences cleanly.
Launch & readiness: Launch checks the storefront build, catalog architecture, B2B features, and integrations together. Readiness is confirmed against the merchant's operating flow, not just the storefront.
Handoff & enablement: Handoff documents the Stencil theme structure, catalog architecture, and B2B configuration. The merchant team operates catalog and pricing through BigCommerce's merchant tools.
Ongoing care & related services: Ongoing care covers theme updates, catalog architecture changes, and new integrations. Related services include multi-storefront rollouts and deeper B2B capability builds.

[ Common questions ]

What is the Stencil theme engine?

Stencil builds BigCommerce storefronts with Handlebars.js, YAML front matter, and Sass/SCSS through the Citadel framework. The Stencil CLI validates and deploys theme assets.

How is B2B capability handled?

BigCommerce adds company-level catalog and pricing rules for B2B. This lets brands separate retail and B2B pricing within the same platform.

What role does the Checkout SDK play?

BigCommerce Catalyst, Stencil, and the Checkout SDK cover different storefront paths. Open Checkout is treated as an open-source reference implementation, and token type and server-to-server access are verified against the current account and platform rules.

How are catalog controls structured?

Catalog architecture organizes products, variants, categories, and brands. Flexible controls let the merchant adjust structure as the catalog scales.

How do integrations stay connected?

REST and GraphQL APIs connect BigCommerce to broader commerce operations. Connected operations keep orders, inventory, and customer data flowing between systems.
