What is the BigCommerce + Manhattan OMS integration

Orders coming in fast is a good problem, until ops has to stitch together inventory, allocation rules, backorders, and shipping updates across channels. In Bigcommerce stores, that usually shows up as oversells, slow “where’s my order” responses, and fulfillment teams working off exports and inboxes instead of a single queue. The Bigcommerce – Manhattan OMS integration connects your storefront to Manhattan as the system of record for order lifecycle and fulfillment decisions. It passes order and customer context into Manhattan and returns inventory availability and order status updates back to Bigcommerce, so what shoppers see and what warehouses execute stay aligned. This fits if Manhattan drives fulfillment in your business and Bigcommerce is your main transactional storefront.

How the BigCommerce Manhattan OMS integration works technically

• Bigcommerce orders are transmitted to Manhattan OMS via API as sales orders, with line items, pricing, taxes, discounts, addresses, shipping method, and payment authorization references mapped to OMS fields.

• SKU, variant, and UOM identifiers are aligned between Bigcommerce catalog entities and Manhattan item masters, with optional mapping for attributes used in sourcing and allocation.

• Inventory availability from Manhattan (by node or aggregated) is synchronized back to Bigcommerce to power storefront stock and backorder messaging, with throttling and retry handling.

• Order status milestones (allocated, released, shipped, canceled, returned) are mapped from Manhattan events to Bigcommerce order and fulfillment statuses, including tracking numbers and carrier codes.

• Customer and address data is mapped with normalization for country, state, and phone formats, and validation errors are logged with correlation IDs for traceability.

• Delta-based syncs send only changed orders, inventory, and shipment records, with idempotent processing to prevent duplicate creates on replays.
