Enterprise use case · Shopify + Amazon Seller + Odoo + Xero
Unified commerce operations
Two channels, an ERP and an accounting system each hold part of the picture, and nobody owns the gaps. Storefront and marketplace activity flows into Odoo and Xero through one governed process.

Shopify actions cover these areas without full create, update and delete for every object. Other Shopify operations use the Shopify API or Rules + Code. Amazon Seller pre-built actions cover FBA and FBM fulfilment operations. Marketplace data outside those actions is read through the Amazon Selling Partner API and normalized in Rules + Code. No Amazon trigger is used: a schedule, HTTP poll or webhook starts the run.
Architecture
One governed run
How it starts: A webhook from the storefront, or a schedule for marketplace activity, starts the run.
