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.
Why choose Seguno over Klaviyo?
Seguno is ideal if you want a simpler, Shopify-native experience that lives inside your admin. Klaviyo is better for stores that need advanced segmentation, predictive analytics, and SMS marketing at scale.
