Frequently Asked Questions

How is EComposer different from PageFly?

EComposer features a live editing experience where changes appear in real time, while PageFly uses a more traditional save-and-preview workflow. EComposer also bundles conversion extensions like AJAX cart directly into the builder.

Does EComposer support Online Store 2.0?

Yes, EComposer fully supports Online Store 2.0 themes and allows you to build both full pages and individual sections that integrate seamlessly with your theme editor.

Can I migrate pages from another page builder to EComposer?

EComposer does not offer automatic migration from other page builders. However, their support team can help recreate pages, and the intuitive editor makes rebuilding pages fast.

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.
