BigCommerce services for every stage of your store

A BigCommerce agency builds and runs the parts of your store the platform does not cover on its own: storefront design and theme code, catalog structure, connections to your ERP and CRM, SEO, and the improvements that follow launch. The platform covers infrastructure and security certification on its own, so agency work concentrates on everything sitting above that layer.

We quote only after reading your store, because averages are useless here. Catalog size sets part of the number and theme customization sets the rest, since a heavily modified Stencil theme costs more to carry through platform updates than a near-stock one. BigCommerce charges you for the license directly, and that sits outside what we invoice.

Yes, and many of our BigCommerce projects start that way. The first step is an audit that reads your theme version, the custom code sitting outside the update path, and the state of your connectors. You get a written verdict on which parts are worth keeping and which are getting more expensive to hold, and that document is yours either way.

A storefront build on a customized theme typically runs two to four months. Migrations depend far more on catalog size and integration count than on the platform itself, so a 500-product store with one connector moves quickly while a 50,000-SKU catalog with ERP and PIM connections takes considerably longer. We give you a dated plan after the audit, not before it.

Check three things before the pitch. Confirm the agency is listed in the official BigCommerce partner directory rather than self-describing as certified. Ask which of their published case studies ran on BigCommerce specifically. Then ask who owns your timeline by name, because the difference between agencies usually shows up in accountability rather than in capability lists.

We work across the standard plans, BigCommerce Enterprise, and B2B Edition. Most of our larger clients are on Enterprise for the API limits and the customer-group controls, and B2B Edition where they sell to trade buyers as well as consumers. If you are unsure which edition your catalog and order volume justify, that question belongs in the audit rather than the sales call.

Yes. BigCommerce exposes its catalog, cart, and checkout through APIs, so a headless front end is well supported. It earns its cost when you are serving several brands or markets from one catalog, or when your content team needs a CMS the platform does not provide. For a single storefront, a well-built Stencil theme usually performs as well for a good deal less money.

Your build team stays with the store. Ongoing work covers bug fixes, platform release testing, connector upkeep, and the incremental improvements that follow a launch, reported monthly against what actually changed. Most clients settle onto a monthly retainer sized to their roadmap rather than a fixed support package.
