Pre-orders, deposits and back in stock for Shopify

Keep selling when you're sold out.

SMART Preorder & Back in stock turns sold-out and coming-soon products into pre-orders, takes a deposit now and charges the balance later, and builds Notify me waitlists that get an email when stock is back. Payment rules for checkout are included.

What it does

One app for selling before, during and after a stockout.

Deposits and partial payments

Deposit now, balance later.

Let shoppers reserve with a deposit, or pay nothing up front. The card is saved at checkout and the app charges the balance on a date, after a set number of days, or when you fulfill, with automatic retries and a payment link if a charge fails.

How it works
Pre-order now button with the line: Pay $22.25 now, $66.75 due when your order ships

Back in stock alerts

Turn sold out into a waitlist.

A Notify me form replaces the dead end on sold-out products. Shoppers leave their email, you see the waitlist, and a restock alert goes out when inventory is back.

How it works
Get notified when it's back popup with an email field, a Notify me button and the line One email when it's back

Payment rules

Control the payment step.

Hide, sort and rename payment methods at checkout with rules, for example cash on delivery only in some countries or below a cart total.

How it works
Checkout payment methods hidden, sorted and renamed by rules
