STOQ

STOQ helps Shopify merchants keep selling when stock runs out: pre-orders, back-in-stock alerts over email, SMS and push, and analytics on what customers are waiting for.

It started life as Restock Rocket, a back-in-stock alerts app. We added pre-orders in 2024, renamed it STOQ, and it now runs on 20,000+ stores.

In 2025 it was picked as one of the Best of Built for Shopify apps at Shopify Editions. It's rated 5.0 across 2,000+ reviews, most of them earned by our Merchant Success team.
