Frequently Asked Questions

Does PageFly work with all Shopify themes?

Yes, PageFly is compatible with all Shopify themes, including Online Store 2.0 themes. Pages are rendered independently of your theme so they work seamlessly regardless of which theme you use.

Will PageFly slow down my store?

PageFly generates clean, optimized code with lazy loading for images and assets. While very complex pages may load slightly slower, most stores see minimal impact on page speed scores.

Can I use PageFly for product pages?

Yes, PageFly supports product pages, collection pages, landing pages, blog posts, homepages, and even custom 404 pages. You can assign custom PageFly layouts to specific products or collections.

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?
