Preorder, Back In Stock ‑ STOQ vs Today's Project Urgency Stockfor Shopify (2026)

Preorder, Back In Stock ‑ STOQ (STOQ) and Today's Project Urgency Stock (TPUS) both aim to improve sales for Shopify merchants, but they approach this goal through very different strategies. STOQ focuses on pre-orders, backorders, and back-in-stock notifications to recapture lost sales due to out-of-stock items. It offers a comprehensive solution for managing waitlists, partial payments, and automated communication with customers regarding product availability, along with Klaviyo integration and multi-location support, targeting merchants with frequent stockouts or those selling products on pre-order basis. TPUS, conversely, leverages urgency and social proof to encourage immediate purchases. It displays stock levels, product views, and recent purchase information to create a sense of scarcity and demand, appealing more to merchants looking to boost conversion rates on existing, in-stock products. The core difference lies in their use cases. STOQ addresses the problem of lost revenue from unavailable items by enabling merchants to still capture sales through pre-orders and backorders, plus re-engage customers who showed interest. TPUS tries to convert website visitors who are currently browsing products into paying customers by highlighting popularity and limited availability. While both can potentially increase sales, they target different stages of the customer journey and address different reasons for cart abandonment or lack of conversion. STOQ provides a full suite of features aimed at inventory management and customer re-engagement related to out-of-stock items, while TPUS functions as an on-page optimization tool promoting urgency and social proof.
