Acconto

Deposits for made-to-order products on Shopify. Customers pay a deposit at checkout, the order waits on hold until it’s made, and the balance is charged to their saved card before it ships.

Install Acconto from the Shopify App Store, then open it from your Shopify admin.

Deposits on any product. A percentage or fixed amount, with the balance due when the order ships, on a set date, or a number of days after the order.
Nothing ships unpaid. Orders stay on hold until the balance is paid, with automatic retries and a payment link if a card fails.
No fees on your sales. A flat monthly price, billed by Shopify.
