BigCommerce Agency

Enterprise Commerce Without the Enterprise Overhead

Vonnda designs, builds, and optimises BigCommerce stores for brands that have outgrown a starter platform but do not want to run their own infrastructure. Open SaaS gives you the APIs and control of a custom build with the reliability and security of hosted software.

We work across the whole platform: storefront design, B2B, multi-storefront, integrations and migrations. We pair BigCommerce with Sanity when you want editorial freedom without giving up a stable commerce back end.

BigCommerce

BigCommerce Services

From storefront design to B2B configuration, integrations, and migrations, we help brands get the most out of what BigCommerce already does well.

  • Storefront Design & Development

    We build fast, on-brand storefronts on Stencil or as a headless front end, designed around how your customers actually buy. Every build is responsive, accessible, and tuned for Core Web Vitals.

    • Stencil themes
    • Page Builder
    • Design system handoff

  • B2B & Multi-Storefront

    Company accounts, customer groups, price lists, quotes, and separate storefronts for different brands or regions, configured and extended so wholesale and direct-to-consumer can run side by side.

    • B2B Edition
    • Price Lists
    • Customer Groups
    • Multi-Storefront

  • Migrations to BigCommerce

    Moving from Magento, WooCommerce, Shopify, or a custom build, we plan the catalogue, customer, and order migration carefully and protect your SEO, URLs, and historical data along the way.

    • From Shopify, Magento, WooCommerce
    • SEO and order history preserved

  • API & Third-Party Integrations

    We connect BigCommerce to the systems the business already runs on: email and SMS, fulfilment, ERP and custom services. The work goes against the platform's own APIs, so the integration survives upgrades instead of being rebuilt after them.

    • Klaviyo
    • ShipStation
    • BigCommerce API

Headless builds with Sanity

A storefront where the price is never wrong

BigCommerce's GraphQL Storefront API pairs well with a dedicated content system. We build headless storefronts backed by Sanity so marketing can shape pages freely while catalogue, pricing, and checkout stay on BigCommerce.

Snakestaff Systems moved off Squarespace onto BigCommerce for commerce and Sanity for content, and brought 62,749 orders and 47,600+ customers with them. BigCommerce owns every number a customer pays; Sanity owns every word a person writes. Nothing is stored twice, so nothing can drift.

Why Choose Vonnda?

We have built and supported commerce on every major platform, which means our BigCommerce recommendations come from comparison rather than habit.

  • Platform-Agnostic Advice

    We recommend a platform after we have looked at everything you need, and when the platform is already decided, we get the most out of it. That judgement comes from running stores on Shopify, Adobe Commerce, WooCommerce, and Commerce7 as well.

  • Built to Be Extended

    Clean integrations with your ERP, PIM, CRM, and fulfilment systems, built on the platform's APIs so upgrades do not undo the work.

  • In-House, Hands-On, Bay Area

    Strategy, design and engineering under one roof. The people who scope your build are the people who build it.
