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 and headless builds 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.

  • Headless Builds with Sanity

    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.

  • 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.

  • 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.

Top Features of BigCommerce

Open SaaS

Hosting, security, and PCI compliance are handled for you, while open APIs and webhooks keep the platform extensible rather than closed.

No platform transaction fees

BigCommerce does not add its own transaction fee on top of your payment provider, and supports a wide range of gateways.

B2B Edition

Company accounts, buyer roles, custom price lists, quoting and invoice payment, native rather than bolted on with apps.

Multi-storefront

Run several storefronts for brands, regions, or B2B and DTC from one control panel, sharing catalogue and inventory where it makes sense.

API-first and headless-ready

A GraphQL Storefront API and Catalyst, BigCommerce's Next.js storefront framework, make a headless build a supported path rather than a workaround.

Headless BigCommerce

A storefront where the price is never wrong

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.

  • Vonnda knocked it out of the park. They delivered high-quality work.

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 will tell you when BigCommerce is the right fit and when it is not. 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

    Strategy, design and engineering under one roof in the Bay Area. No outsourcing, and the people who build your store are the people you talk to.
