Preorder App for Shopify

How it works

Up and running in minutes

Enable preorder on your products

From the DemandLoop dashboard, select any out-of-stock product and enable preorder. Set an expected ship date, optional quantity limit, and preorder price. Takes under a minute.

Customers purchase immediately

Shoppers see a 'Preorder Now' button instead of 'Out of Stock'. They add to cart and check out normally through Shopify — payment collected immediately.

Fulfill orders when inventory arrives

Preorders appear in your Shopify Orders tagged 'preorder'. When stock arrives, fulfill normally. DemandLoop automatically sends customers a shipping notification.

Why DemandLoop

Everything you need, nothing you don't

Guaranteed revenue — not just emails

Unlike back-in-stock subscriptions (20% avg. return rate), preorders convert at 100%. Customers commit with payment — no 'maybe later'.

Expected ship date on product page

Display a transparent ship date directly on the product page. Customers know exactly when to expect delivery — fewer support tickets.

Quantity limits to prevent overselling

Cap preorders at a safe number (e.g., 80% of expected stock). DemandLoop stops accepting preorders automatically when the limit is reached.

Preorder pricing — discounts or full price

Offer an early-bird discount to incentivize preorders, or charge full price for high-demand items. Configurable per product.

Works as backorder, presale, or coming soon

Different stores use different terms — pre-order, presale, backorder, coming soon. DemandLoop handles all these scenarios with one flow: show a reserve button, collect payment, fulfill when ready. No separate tools needed.

FAQ

Common questions

How does the Preorder Now button appear on my Shopify store?

DemandLoop uses Shopify's Theme Extension framework to replace the disabled 'Add to Cart' button with a 'Preorder Now' button on out-of-stock products. No Liquid code edits needed.

When is the customer charged for a preorder?

Immediately at checkout — same as a regular Shopify order. The customer pays the full (or discounted) preorder price when they place the order.

What if my inventory is delayed after a customer preorders?

Update the expected ship date in DemandLoop — subscribers receive an automatic delay notification email. Transparent communication reduces cancellations.

Can I run preorders and back-in-stock notifications on the same product?

No. When preorder is enabled for a product, DemandLoop shows 'Preorder Now' instead of 'Notify Me'. You choose the strategy per product.

Is preorder available on the free plan?

Preorder is a Growth plan feature. You can start a free trial to test it on your store before committing.

Is preorder the same as a backorder or presale?

Effectively yes — all three mean taking orders before stock is available. 'Preorder' is common for upcoming or new products, 'presale' for limited-edition launches, and 'backorder' for restocking items. DemandLoop handles all three scenarios with the same Preorder Now button and fulfillment flow.
