Frequently Asked Questions
Does GemPages include A/B testing?
Yes, GemPages includes built-in A/B testing on the Build plan and above. You can test different page versions and track conversion rates directly within the platform without needing a separate tool.
What is the post-purchase upsell feature?
The post-purchase upsell feature lets you create one-click upsell offers that appear after checkout but before the thank-you page. Customers can accept offers without re-entering payment details, increasing average order value.
Can GemPages replace my Shopify theme?
GemPages works alongside your existing theme rather than replacing it. You can use GemPages for specific pages like landing pages and product pages while keeping your theme for the rest of your store.
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.
