BigCommerce integration

Turn BigCommerce into a multi-vendor marketplace. Across every storefront.

Esetrix plugs into your existing BigCommerce store through native API v3, webhook, and Channels API integration. Add suppliers, automate fulfilment, and operate a curated marketplace in 6 to 8 weeks. Stencil, headless, Catalyst, and B2B Edition all supported.

Capabilities

Everything a marketplace on BigCommerce needs. Across Stencil, headless, Catalyst, and B2B.

Product sync, order routing, supplier settlement, Multi-Storefront governance, and headless-ready architecture. Delivered through BigCommerce's native APIs rather than stitched on top of them.

Bidirectional product sync
Catalogue, variants, modifiers, SKUs, pricing, and custom fields flow both ways between Esetrix and BigCommerce. Supplier catalogues publish directly to the right categories and brands.
Real-time inventory across locations
Supplier stock updates propagate in seconds through BigCommerce's inventory API. Multi-location inventory per supplier, allocation rules, and safety thresholds.
Order routing & split fulfilment
Multi-supplier orders split automatically into supplier-specific purchase orders. Line items route by SKU ownership; shipment events return to the original BigCommerce order.
Commission & settlement
Commission per supplier, category, storefront, or customer group. Automated reconciliation, supplier payout runs, and settlement statements generated from BigCommerce order data.
Multi-Storefront & Channels API native
Each storefront is a distinct channel. Pricing, availability, and supplier rules can differ per storefront, managed centrally in Esetrix and pushed through the Channels API.
Headless and Catalyst ready
Works identically behind Stencil, custom headless front ends, and Catalyst on Next.js. Storefront technology is independent of the marketplace layer.
Architecture

How data flows between BigCommerce and Esetrix.

Bidirectional synchronisation via BigCommerce API v3, webhook topics, and the Channels API. Event-driven, with an immutable audit log on the Esetrix side.

Event-driven by default. Esetrix subscribes to BigCommerce webhooks for orders, shipments, inventory, and refunds. No polling, no rate-limit risk, immediate propagation across every storefront channel.
Setup

Four steps from contract to live marketplace.

The Esetrix implementation team owns setup end to end. No systems integrator, no outsourced development.

01
Provision API account & webhooks
Create a scoped BigCommerce API account for Esetrix with only the required OAuth scopes. Register webhook topics for orders, shipments, inventory, and refunds. No store downtime.
02
Map catalogue, channels, and custom fields
Guided mapping of BigCommerce categories, brands, custom fields, and Channels API entries to Esetrix supplier and category structures. Price Lists and Customer Groups map to marketplace commercial rules.
03
Define commission & routing rules
Set commission by supplier, category, SKU, storefront, or customer group. Configure order-routing, fulfilment SLAs, and supplier payout cadence.
04
Onboard suppliers and go live
Esetrix onboards suppliers in parallel with technical setup. Typical path is 6 to 8 weeks from contract to live marketplace on your existing BigCommerce store.
Frequently asked

Questions BigCommerce teams usually ask.

No. Esetrix integrates at the BigCommerce API v3 and webhook layer. Your Stencil storefront, headless front end, or Catalyst build remains unchanged. Product data, inventory, and orders flow between Esetrix and BigCommerce in the background.
