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.

Hi @TheVeganist ,

We had success implementing some of our clients using Order Fulfillment Guru. It’s a Shopify app that automates order routing to your suppliers. It handles order-splitting really seamlessly and you can see the split orders directly in your Shopify Admin (instead of going into another app). Many of our clients like to use Shopify as the hub of orders. Your supplier handles the shipping. The app uses your existing Shopify email & SMS notifications to notify customers of order updates (so it can be customized any way you want, including adding invoice PDFs). Since all the data is in Shopify, it can integrate into any accounting software that Shopify already integrates with (some of our clients use QuickBooks Online and Xero).

Good luck and let me know if you have any questions.
