BigCommerce Development Services

Codinative is a BigCommerce-only engineering team. We design and build custom storefronts, checkouts, apps, and integrations that are fast, secure, and easy to scale. Whether you’re on Stencil or going headless, we handle everything from UX and performance to complex B2B, Multi-Storefront, and API-driven automations.

Platform expertise that matters: Stencil/Handlebars & Stencil CLI, Open Checkout & Checkout SDK, GraphQL Storefront API, REST v3 APIs, webhooks, and the B2B Edition toolkit. (BigCommerceDevs, BigCommerce Support)

Custom Storefront Development (Stencil & Headless)

Stencil theming (front end)

We craft conversion-first themes with clean, accessible UI and performance baked in.

  • Custom templates, regions, partials, and helpers (Handlebars/SCSS/JS)
  • Local development with Stencil CLI (safe previews, BrowserSync)
  • Page Builder-friendly components and widgets
  • Lighthouse/Core Web Vitals optimization
Why this matters: Stencil is BigCommerce’s Handlebars-based theme engine, and Stencil CLI enables safe local development without touching the live store. (BigCommerceDevs)
Headless storefronts (Next.js/React)
  • GraphQL queries for fast product/category/cart rendering
  • ISR/SSG for speed at scale, REST v3 for admin automations
  • Secure auth flows, promos, and personalization
  • Seamless CMS (Contentful/WordPress) and search (Algolia) integrations
Why this matters: The GraphQL Storefront API powers modern headless builds and can also be used inside Stencil themes. (BigCommerceDevs)
Deliverables: UX/UI system, theme or headless repo, performance budget, accessibility checks, deployment plan.
Custom Checkout & Cart (Open Checkout + Checkout SDK)

We design and implement brand-matched, high-converting checkouts:

  • UI/UX re-skins and custom steps (guest/express/B2B flows)
  • Payment method logic (wallets, BNPL) and validation rules
  • Address verification, shipping estimates, tax display logic
  • Error handling, analytics events, and A/B test hooks
Why this matters: BigCommerce supports Open Source Checkout and a Checkout JS SDK for bespoke experiences, including custom loaders and local dev. (BigCommerceDevs)
Deliverables: Custom checkout bundle, SDK integration docs, QA scenarios, rollback plan.
B2B on BigCommerce

For distributors and manufacturers needing complex buying workflows:

  • Company accounts, roles/permissions, and quick order experiences
  • Shared/private catalogs, price lists, and quote workflows
  • Payment terms and re-order tools
  • Punchout and ERP connectivity (via apps/integrations)
Why this matters: B2B Edition provides company accounts, quotes, and buyer-side tools designed for enterprise B2B scenarios. (BigCommerce Support)
Deliverables: B2B Edition setup, UX flows, price/quote configs, integration runbooks.
Apps & Integrations (Private/Public)

We build embedded or standalone apps to extend your store:

  • ERP/CRM/PIM/OMS (NetSuite, MS Dynamics, Salesforce, Akeneo)
  • Search, recommendations, analytics, reviews, loyalty
  • Shipping, tax, payments, and fraud tools
  • Custom middleware, ETL, and webhooks for real-time syncs
Why this matters: BigCommerce exposes REST and GraphQL APIs plus webhooks for robust integrations; apps authenticate securely with OAuth. (BigCommerceDevs)
Deliverables: App code, OAuth setup, scopes, install guide, monitoring.
Data & Platform Migrations
  • Shopify/Magento/WooCommerce → BigCommerce
  • Clean product/customer/order migrations with redirects and metadata carryover
  • URL mapping, faceted navigation parity, and analytics continuity
Deliverables: Migration playbook, dry-runs, final cutover plan, post-launch QA.
Ongoing Engineering (SLA & Roadmaps)
  • Monthly retainers for feature sprints and maintenance
  • Monitoring (errors, uptime, webhooks, feeds)
  • Versioning, staging, and rollback procedures
  • Analytics experiments and CRO backlog
Deliverables: Prioritized roadmap, monthly KPIs, release notes.
