Paid plans start at $10/month (Lite) and go up to $69/month (Ultimate) for unlimited preorders and email/SMS alerts, each with a 14-day free trial.
How long does setup take — can I do it without a developer?
Setup is designed to be self-serve and takes only minutes. STOQ uses an app embed that auto-detects your theme, and you simply toggle it on in the Theme Editor — no code required. The support team is also available 24/7 and merchants report that even theme-integration hiccups are resolved within minutes or a few hours.
Does it work with my existing Shopify theme?
STOQ requires an Online Store 2.0 theme to use app embeds — older legacy themes are not supported and would need to be upgraded first. The app supports product pages, collection pages, home pages, quick buy buttons, and custom pages, and its team will help match the widget styling to your brand.
Does it integrate with Klaviyo, Omnisend, Mailchimp, or Shopify Flow?
Yes — STOQ natively integrates with Klaviyo (via OAuth), Mailchimp, Omnisend, Shopify Flow, and Shopify POS. Klaviyo integration lets you sync your mailing list and trigger back-in-stock emails directly through Klaviyo, and Shopify Flow triggers are available for preorder and restock events.
Do back-in-stock alerts and preorders work for specific product variants and multiple locations?
Yes, alerts are triggered at the variant level (e.g., a specific size or color), so customers are only notified when their exact variant is restocked. STOQ also supports multiple store locations and Shopify Markets, allowing multi-country preorder settings, localized experiences, and currency support.
What do other merchants say about the app and its support team?
STOQ holds a 4.9-star rating across 2,830+ reviews on the Shopify App Store, with 97% being 5-star. Merchants consistently praise the responsive 24/7 live chat support — describing the team as quick to resolve issues, often within minutes — and highlight the app's reliability for managing preorders and restock workflows across diverse store types.
Are there any transaction fees on preorders, and what happens if I exceed my plan's limits?
STOQ charges no transaction fees on any plan. If you exceed your monthly preorder limit, overages are billed at $0.25 per preorder on the Lite plan and $0.10 on the Pro plan; the Ultimate plan at $69/month includes unlimited preorders with no overage charges. SMS notifications carry an additional $0.025 per message on all paid plans.
