Frequently Asked Questions

How does STOQ handle preorder payments?

STOQ supports both full payment and partial payment preorders. With partial payments, customers pay a deposit at checkout and the remaining balance when the product ships, reducing friction for high-value items.

Does STOQ automatically detect out-of-stock products?

Yes, STOQ syncs with your Shopify inventory in real time. When a product sells out, the buy button automatically switches to a preorder or notify-me button without any manual intervention.

Can I use STOQ for product launches?

Yes, STOQ includes a coming soon page feature that lets you build anticipation for upcoming products. Customers can sign up for launch notifications and optionally place preorders before the official release date.
