BigCommerce agency partner for headless and B2B.

A BigCommerce agency partner designs, builds, and runs stores on the BigCommerce platform for its clients: custom design and development, BigCommerce integrations, data migration from other platforms, and ongoing support after launch. BigCommerce describes its Agency Partner Program as the program for agencies that build eCommerce solutions and deliver custom experiences for their clients.

Yes. Brainvire is a BigCommerce Certified Partner and a BigCommerce B2B Specialized Partner, the two partner credentials shown in the badges on this page. We work as a BigCommerce partner agency across store builds, migrations, integrations, and support.

BigCommerce's documentation describes three partnership programs. The Agency Partner Program is for agencies that build eCommerce solutions for clients, the Technology Partner Program is for companies that design themes, custom apps, and business software integrations, and the Affiliate Partner Program is for marketers who promote BigCommerce through referral links and banners. BigCommerce says the program includes resources, training, sales enablement, partner support, and a referral network.

According to BigCommerce's documentation, an agency applies through the Partner Portal with a company email address, selects the program type, and completes member registration; partner credentials arrive by email once the application is approved, which can take up to two days. BigCommerce states that partners must complete its Partner Portal training modules to become a BigCommerce Certified Partner.

BigCommerce's docs name the BigCommerce Channel Account Manager as the partner's contact when credentials do not arrive after approval, and point partners to their account manager to register for the BigDev Bootcamp: advanced sessions on the Catalog, Orders, Cart and Checkout, and Storefront APIs and Stencil.

Start by defining the project scope, then ask each agency for relevant case studies, its partner status, how it will connect your existing systems, and what post-launch support looks like. A low estimate without a clear scope often leads to unexpected costs later, so compare proposals against the same scope. The right partner starts with a discovery phase before any code is written.

An agency brings platform expertise and people across design, development, integration, and support, which can shorten time to market. Handing the technical work to a partner keeps your internal team focused on running the business, and experienced partners have often solved the same catalog, checkout, and ERP problems before.

Our BigCommerce services cover store implementation, headless builds on Catalyst, B2B Edition, multi-storefront, platform migration, ERP, OMS, and PIM integration, conversion optimization, and managed support. An engagement can start with one of these BigCommerce solutions or cover the full lifecycle, from design and development to run-and-optimize.

BigCommerce offers B2B Edition for business buyers: company accounts, buyer portals, sales quotes with negotiated pricing, shared lists, and invoice payments on net terms. Customer groups can also control what certain customers see in the store. As a B2B Specialized Partner, we configure these around account-based pricing and the price rules your ERP already holds.

Yes. BigCommerce describes Catalyst as its composable, fully customizable headless storefront framework, built with Next.js, React, and the GraphQL Storefront API, and says it supports product catalogs of any size, complexity, or update frequency. We choose it when a brand needs front-end freedom; for a simpler store, a Stencil theme can be faster to launch.

Yes. Our BigCommerce migration services move an eCommerce website off Magento, WooCommerce, Shopify, or a custom platform onto a new BigCommerce website: data migration for products, customers, and orders, URL redirects to protect search rankings, and a rehearsed cutover. We validate the migrated data before launch and plan the switch around your trading calendar.

It depends on scope. A store on a customized theme with standard integrations can go live in weeks, while headless builds, B2B Edition rollouts, and multi-storefront programs with ERP integration take longer. Most BigCommerce work starts with discovery, and we confirm the timeline once the catalog, integrations, and data are mapped.

ERP integration with Odoo, SAP, NetSuite, and Dynamics; OMS and PIM connections; payments, tax, shipping, search, and marketing tools from the technology providers you already use. We connect BigCommerce through its APIs and webhooks and design each sync around its API rate limits, since BigCommerce says all apps accessing a store share that store's quota.

Yes. When no app in the BigCommerce App Marketplace fits, we handle the custom development: private apps for a single store, built on BigCommerce's APIs and SDKs, that add advanced functionality without changing the core platform, which helps keep upgrades simple.

BigCommerce states that it is a PCI DSS compliant service provider and validates annually all requirements (1-12), and merchants can use its Attestation of Compliance for the part it covers. If your application handles credit card data, it needs to be PCI compliant too, so on any eCommerce store we build, card data stays inside BigCommerce checkout or the payment provider wherever possible.

Often, yes. As open SaaS, it gives mid-market and enterprise teams a hosted core plus APIs for headless builds and integrations, so the team spends less time on hosting and more on the store. We check the fit against your catalog, B2B needs, and existing systems before recommending it over other eCommerce platforms.

BigCommerce hosts the core platform as SaaS, so its infrastructure is not something your team runs. Before peak season we still load-test the storefront, checkout, and integrations for high traffic volumes, because slow ERP or search calls are often the first bottleneck on a BigCommerce site.

Multi-storefront runs several storefronts from one BigCommerce store and back office. BigCommerce's docs describe a setup where each country storefront has its own language, currency, payment method, and pricing through price lists, managed in the Channel Manager. We use it to launch new brands and regions from one catalog.

Managed support under SLA: releases, monitoring, app and theme updates, and a roadmap of improvements, so the store keeps getting better after go-live. We also tune conversion, search, and the customer experience.

We build AI into search, product recommendations, shopping assistants, and catalog enrichment instead of adding a chatbot at the end, so the store itself gets smarter. Behind the scenes, AI-assisted catalog and order sync cuts manual work across your systems.

Cost follows scope: the number of storefronts, integrations, and custom apps, and the volume of data to migrate. We price after a discovery phase, because a clear scope protects you from the unexpected costs that often follow a low estimate.
