Adding a new vendor

How to add a new supplier or vendor to PO Flow.

Adding a new vendor

In PO Flow, suppliers and vendors are managed in the Suppliers section. Every purchase order must be associated with a supplier, so you will need to add your suppliers before creating POs.

How to add a supplier

  1. Click Suppliers in the left navigation.
  2. Click New Supplier.
  3. Enter the supplier's company name.
  4. Add their email address — this is used when sending PO emails and return emails.
  5. Optionally add phone number and address.
  6. Click Save.

After saving

Once the supplier is created you will be taken to their profile page. From here you can:

  • Add contacts (individual people at the supplier)
  • Add notes
  • Link to a Shopify vendor name (recommended)
  • View their purchase history and performance metrics

Linking to a Shopify vendor

Go to the Purchasing Settings tab on the supplier profile and click the Shopify Vendor Name field. A searchable dropdown shows all vendor names currently used on products in your Shopify store. Select the matching vendor to link the supplier. This enables accurate reporting and helps with order imports.
