One such strategy is effective back-in-stock alert management. By enabling customers to sign up for restock alerts, businesses can retain interest and minimize the chance of losing a potential sale to competitors. In this blog, we delve into two powerful back-in-stock alert apps - Back in‑stock Restock Alert ZA and ZeroOut. Each of these apps has the potential to effectively manage out-of-stock scenarios and help businesses drive sales.

How Does Back in‑stock Restock Alert ZA Work?

Developed by Zooomy, Back in‑stock Restock Alert ZA acts as your sales soldier by notifying customers once their desired items are back in stock. Amid a plethora of features, the app allows for automatic emails, customizable text display, and much more. Now, consider for a moment that you run a mid-size apparel business and a popular product goes out of stock. With Back in‑stock Restock Alert ZA, your customers can simply subscribe for a restock alert and get an instant notification when the product is available, improving the customer shopping experience and boosting loyalty toward your brand.

How Does ZeroOut Work?

Created by Valence Labs, ZeroOut moves beyond just alerting customers when a product is available. The app hides out-of-stock products, collects back-in-stock emails strategically, and responds promptly when the product is back in the inventory. This means, if you're a small baking supplies business and run out of yeast, ZeroOut ensures your customers don't see what they can't buy, efficiently managing customer expectations.

How Much Does Back in‑stock Restock Alert ZA Cost?

Back in‑stock Restock Alert ZA offers four distinct pricing tiers to cater to diverse business sizes. - The Free tier, offering 10 subscribed items and 10 emails per month, is perfect for beginners. - The Pro tier, priced at $5.99/month, increases the capacity to 300 subscriptions and 100 emails per month and brings in automatic emails and removes branding. - The Premium Tier ($19.99/month) offers up to 1000 emails per month, collection page integration, location feature, and Klaviyo integration, ideal for growing businesses with consistent inventory movement. - The Advanced Tier ($39.99/month) ramps up the offerings to 3000 emails and subscriptions per month and comes with all the Premium features. A good match for large-scale e-commerce businesses.

ZeroOut employs a three-tier pricing approach. - The Basic plan at $9/month offers unlimited products and generates a daily activity report. - The Standard plan ($19/month) includes low stock alerts and up to 500 back-in-stock notifications. - The Professional tier ($29/month), apart from the Standard features, provides 2500 back-in-stock notifications. Although the integrations are "coming soon," seeing the tier's offerings, it seems well-suited for scaling e-commerce businesses.
