CS
China Sourcing OS
ERPNext foundation, custom sourcing operations layer
Open Internal OS
Same system, clearer front door

One operating system for sourcing, money, QC, warehouse, and shipping.

This site runs on ERPNext/Frappe, but daily staff work starts in the custom China Sourcing OS. The ERP screens remain available for accounting and document detail; the operations layer keeps the workflow simple and connected.

Orders
Customer request to shipment, connected through one flow.
Payments & FX
Customer funds, supplier payments, exchange, and profit review.
QC & Warehouse
Inspection evidence, holds, storage, and consolidation.
Customer-Safe Reports
External output hides supplier costs, margins, and internal notes.
Portals
Customer and supplier views are safe product surfaces, not raw ERP screens.
