Notify Me vs Square Online: pros and cons
Notify Me
Notify Me! turns sold-out pages into waitlists, pre-orders, and wishlists, then feeds demand signals into Klaviyo, Mailchimp, Omnisend, and PushOwl. Its 4.9/5 rating across 3,400-plus reviews shows real recovery power, but it's locked to Shopify and BigCommerce and SMS costs vary by country. Overall, it's a strong pick for stores losing sales to stockouts.
Pros
- Bundles four revenue-recovery tools — back-in-stock alerts, pre-orders, wishlists, and low-stock reminders — into one app, replacing what would otherwise require several single-purpose subscriptions
- Proven at scale — 35,000+ Shopify and BigCommerce stores, $502M+ in recovered merchant sales, and a 4.9/5 Shopify App Store rating across 3,400+ verified reviews with 97% five-star feedback
- Alerts sync natively into Klaviyo, Mailchimp, Omnisend, and PushOwl, and widgets work with page builders like PageFly, GemPages, and EComposer — no CSV exports or glue code required
Cons
- Built exclusively for Shopify and BigCommerce — merchants on WooCommerce, Magento, or custom platforms can't use it
- SMS and WhatsApp messages are billed separately at rates that vary by country, so total notification costs are hard to predict until you check the per-country rate tables
- Setup isn't fully self-serve — some reviewers needed support help integrating widgets with their themes or handling product variants
Square Online
Square Online makes it easy to launch a store that shares inventory, orders, and payments with your Square POS, and the free plan with included hosting removes upfront costs. Design flexibility is limited and you're tied to Square's ecosystem for payments. Overall, it's a low-risk pick for Square users, but less compelling for anyone else.
Pros
- Free plan with free web hosting lets you launch a store with no upfront infrastructure cost
- Inventory, orders, and payments sync natively between Square POS and the online store, eliminating manual reconciliation
- No coding or web design experience is required to publish a professional-looking site
Cons
- Design and customization are more limited than what dedicated website builders or self-hosted platforms like WooCommerce offer
- The tightest benefits only apply if you stay within the Square ecosystem, so merchants using other payment processors or POS systems get less value
- Advanced ecommerce features and lower processing rates generally require moving up to paid plans, and costs grow as you add capabilities
