BigCommerce ERP integration

BigCommerce is a SaaS storefront popular with mid-sized and B2B sellers. Connecting it to your ERP keeps stock accurate, sends orders straight to fulfilment and posts sales correctly in accounting.

02Use cases

Common use cases

01

B2B storefronts

Customer groups and price lists driven from the ERP.

02

Multi-channel stock

One stock figure for BigCommerce, marketplaces and wholesale.

03

Automated fulfilment

Orders flow to picking without re-keying.

03 — Architecture

API architecture

Webhooks notify the integration of new and updated orders; payloads are verified, queued and processed asynchronously. Outbound updates use the REST API in batches within rate limits, and a scheduled reconciliation catches missed events.

04Reliability

Authentication, errors and retries

01

Authentication

A store API account with scoped OAuth access tokens, stored in a secrets manager.

02

Error handling

Each order is processed with its BigCommerce ID as an idempotency key; failures go to an exception queue with the reason.

03

Retry strategy

Exponential backoff for transient errors, then a dead-letter queue and alert.
