Automatically hold Preorder orders (Alternative to REZ Shippings)

Use this workflow when you want Shopify to automatically put an order on fulfillment hold whenever the order contains the tag PREORDER.

When to use this method?

Use this method when you:

• Want to use payment providers other than Shopify Payments

• Want to combine preorders with third-party apps (for example: subscriptions or bundles)

In these cases, you cannot use Shopify Selling Plans, which means REZ Discount, REZ Partial Payment, and REZ Shipping are not available.

Make sure you already installed Shopify flow (Native Shopify app and is free to install)

We will create a flow like this

We have full flow setup tutorial video available here

Step 6: Test the Workflow

To verify:
