What It Is

Back in Stock is Amp’s back-in-stock alert and pre-order app for Shopify merchants. Its core use case is capturing buyer demand when products are sold out through a “Notify Me” button, forms, and pop-ups, then automatically notifying users via email, SMS, or Web Push after restocking. The copy indicates that it has Built for Shopify status, with 112,000+ installs and 790+ five-star reviews on the Shopify App Store, making it a relatively mature vertical tool.

Core Capabilities and E-commerce Value

The tool is not just about sending restock reminders; it turns lost demand during out-of-stock periods into actionable data. Merchants can customize buttons, forms, pop-ups, and email styles to match their Shopify theme, with support for multilingual notifications. After items are restocked, alerts can be sent within 60 seconds, while merchants can also control notification pacing and audience size to avoid sudden order spikes. The built-in pre-order feature helps collect intent before new products arrive and convert that interest into orders, with options for full payment, partial deposits, or discount incentives. Its analytics module tracks notification conversions, sales impact, and high-demand out-of-stock products, supporting decisions around replenishment, product selection, cross-selling, and upselling.

Pricing and Integrations

Pricing follows a free plan plus monthly subscription model. All plans include the full feature set, with the main difference being monthly notification volume. The free plan includes 10 notifications per month; paid plans range from Lite at $19/month to Enterprise 1m at $999/month, covering 50 to 1 million notifications, with a 14-day free trial available. If merchants exceed their quota, they can upgrade or purchase additional notifications as needed. Integrations include Shopify, Klaviyo, Mailchimp, Campaign Monitor, Constant Contact, Zapier, and PageFly, making it suitable for brands that already use email marketing and page-building tools.

Pros and Cons

The main advantages are easy installation, no-code setup, and a focused use case. It creates a closed loop from out-of-stock subscriptions and notification delivery to pre-order payments and demand analysis. All plans include all features, which is friendly to smaller merchants. The drawbacks are that the available copy only clearly confirms Shopify support, with no stated support for WooCommerce or other platforms. Specific pricing, regional coverage, and sending limits for SMS and Web Push are not explained. Information about enterprise-level service, SLAs, and support channels is also incomplete. For merchants with frequent notifications, costs can rise quickly as notification volume increases.

Who It’s For and Access from China

Back in Stock is suitable for Shopify independent stores, DTC brands, retailers with noticeable inventory fluctuations, and teams that want to use out-of-stock demand to guide replenishment and new-product pre-orders. Access from mainland China is not addressed in the copy. Payment methods are also only mentioned in the context of pre-order payment options, with no disclosure of which payment methods are supported for the app subscription itself. Chinese sellers should specifically verify Shopify admin availability, SMS regional coverage, billing payment options, and compatibility with Klaviyo/Mailchimp or alternative marketing tools.
