What is EZ Preorder & Back In Stock?

All plansLast verified 11 November 2026View as Markdown

EZ Preorder & Back In Stock is a Shopify app that lets a store sell products before they are in stock (preorders) and lets shoppers sign up to be emailed when a sold-out product is back (restock alerts, also called back in stock alerts or Notify Me). It replaces your theme's add to cart button with a preorder button, can take a deposit now and charge the balance later, and sends restock alert emails automatically when inventory returns. It is built by Casual Ecommerce Apps, carries Shopify's Built for Shopify badge, and has a free plan; paid plans cost $10, $20, $30 or $50 a month.

Available on: All plans, including Free. Some features need a paid plan; each one is listed below.
Where to find it: EZ Preorder & Back In Stock on the Shopify App Store. After you install it, it appears in your Shopify admin under Apps as EZ PreOrder.

What EZ Preorder does

EZ Preorder & Back In Stock does two jobs for a Shopify store:

  1. Preorders. Shoppers buy a product that is out of stock, not yet released, or made to order. They pay at your normal Shopify checkout, in full or as a deposit. The order is tagged preorder so you can find it and fulfill it when stock arrives.
  2. Restock alerts. When a product is sold out, shoppers click a Notify Me button and leave their email address. When the product's inventory goes back above 0, EZ Preorder emails each of them a link back to the product.

You can use either one alone or both together. Each product is set up as a preorder or as a restock alert product, depending on whether you want to take orders now or collect a waitlist.

Who EZ Preorder is for

EZ Preorder suits Shopify stores that:

  • Launch new products and want to take orders before release. See Launch a new product with preorders.
  • Sell out regularly and want to keep selling while stock is on its way (backorders), instead of losing the sale.
  • Make products to order and want a deposit up front. See Sell made-to-order products with deposits.
  • Run limited drops and want to cap the number of preorders.
  • Want a waitlist for sold-out products, to measure demand and win back shoppers when stock returns.

How EZ Preorder works in your store

EZ Preorder & Back In Stock works through your Shopify theme and your normal Shopify checkout:

  1. The app embed called Pre order theme extension loads EZ Preorder on your storefront. You turn it on once in Online Store → Themes → Customize → App embeds. See How to install EZ Preorder and enable the app embed.
  2. Your Preorder List in the app holds the products and variants you sell as preorders, each with its rule. See How to manage your Preorder List.
  3. On the product page, EZ Preorder swaps the add to cart button for the preorder button whenever a variant's rule matches its stock. The item goes into the cart with the line item property type: preorder.
  4. At checkout, Shopify accepts the order because EZ Preorder turns on Continue selling when out of stock for variants with the Always and Sold out rules.
  5. After the order, EZ Preorder tags it preorder, can put it on hold and email the customer, and counts it toward your plan.

The full lifecycle is in How preorders work in EZ Preorder. Restock alerts work through a separate theme block, EZ PreOrder - Notify Me; see What are restock alerts and how do they work?.

Requirements and compatibility

  • Shopify Online Store. EZ Preorder shows its buttons on your Online Store theme. The Notify Me, Free Gifts and Preorder Featured Product blocks need an Online Store 2.0 theme, which supports app blocks.
  • Themes. EZ Preorder includes settings presets for 358 themes, including Shopify's free themes such as Dawn. Most themes work without changes. See What Shopify themes work with EZ Preorder.
  • Inventory tracking. Preorder rules and restock alerts read Shopify inventory, so turn on Track quantity for those products.
  • Deposits. Partial payments work with Shopify Payments and PayPal Express. See How to take deposits and partial payments on preorders.
  • Markets and languages. Preorders can be limited by country with Shopify Markets, and the button text and custom note can be translated into each published language.
  • Admin languages. The EZ Preorder admin is available in English, French, Spanish, German and Italian.

Limitations

  • EZ Preorder changes your Online Store only. It does not add preorder buttons to Shopify POS, draft orders or other sales channels, though an order from another channel is still tagged preorder if the variant matched its rule.
  • The Preorder List works best with up to about 600 products at once.
  • Partial payments are one store-wide setting, not set per product.
  • Turning a preorder off does not turn off Continue selling when out of stock. Check that setting so the product does not keep selling. See Why a product still sells after its preorder is turned off or ends.
