Back-in-stock alerts + pre-orders for Shopify

Never lose a sale to a stockout.

Restocker turns sold-out products into recovered revenue. Shoppers join a waitlist and get emailed the moment you restock, or keep buying with pre-orders. Flat pricing, provable delivery, no surprises.

Free plan · No code · Theme app extension only

Everything you need, nothing you don’t

Built from the complaints merchants have about every other app.

Back-in-stock alerts

Shoppers tap “Email me when it’s back” on any sold-out product and get an automatic email the moment you restock.

Pre-orders that can’t oversell

Keep selling sold-out items with native Shopify selling plans, so Shop Pay and express checkouts can never oversell you.

Proof it was delivered

Every notification writes to a permanent log: what was sent, to whom, when, and whether it actually arrived.

Flat pricing, always

Free, $9, or $19 a month. No percentage of your sales, no per-email metering, no surprise cutoffs mid-restock.

No theme code, ever

A theme app extension, so nothing is injected into your theme and uninstalling leaves zero residue behind.

Your data is yours

Export your whole waitlist to CSV any time, free and unlimited. No lock-in, no paywall on your own data.

See it in action

From a sold-out product page to proof the email landed.

Step 1

Capture demand on the product page

A clean “notify me” box appears only when a variant is sold out, and stays hidden when it’s in stock.

Step 2

Keep selling while you restock

Turn the buy button into a pre-order with native selling plans, so a stockout never means a lost sale.
