Have you had a look at Unleashed, Cin7 and Dear?
These are the most common in my region and could all handle your requirements.
Topic summary
A merchant seeks an app to automate order fulfillment with custom suppliers (primarily startups manufacturing their own products) while synchronizing inventory across systems. Key requirements include automatic order routing to suppliers, real-time inventory updates at both shop and supplier locations, and ideally customer email notifications, invoice generation, and accounting software integration.
Multiple solutions have been proposed:
Specialized Apps:
- Order Automator: Automates fulfillment and vendor notifications based on custom rules
- Order Fulfillment Guru: Routes orders to suppliers with split-order handling directly in Shopify Admin
- Duoplane: Comprehensive solution offering automatic order splitting, supplier routing, inventory syncing (via CSV/Google Sheets/EDI), and QuickBooks/Xero integration
- Simple Purchase Orders: Generates purchase orders from customer orders and emails suppliers
Inventory Management Platforms:
- Unleashed, Cin7, Dear: Full-featured systems commonly used for these workflows
- Fabrikator: Supply planning with purchase order automation (enterprise plan)
- Prediko: Custom solution for 3 of 5 requirements
Custom Development:
- BundleSync and JoesIdeas offer tailored integrations depending on supplier systems and specific API capabilities
Note: One commenter warned against Order Fulfillment Guru due to alleged unethical practices by its developers. The discussion remains open with no final decision indicated.
