How We Built a Real-Time Shopify Inventory Alert & Restock Engine

Every day, thousands of Shopify merchants quietly lose 10% to 15% of their potential sales simply because products go out of stock without anyone noticing.

When a bestseller sells out unexpectedly, three costly things happen:

Shoppers bounce straight to your competitor.
Paid ads continue spending budget on dead-end product pages.
Your brand loses customer trust and repeat orders.

To eliminate this revenue leak, we launched Stockly — a complete Shopify inventory protection and back-in-stock automation platform.

How Stockly Protects Your Store's Revenue:

⚡ 1. Real-Time Multi-Channel Alerts

Never get blindsided by an empty shelf again. Stockly monitors your catalog continuously and sends instant alerts directly to:

Slack (instant notifications to your #inventory-alerts channel)
WhatsApp (immediate pings to purchasing managers)
Email (custom daily & weekly inventory summaries)

🔔 2. No-Code "Notify Me When Available" Waitlists

Don't let sold-out product pages be dead ends. Stockly automatically embeds a sleek restock signup form on out-of-stock items. The moment you restock, automated emails notify eager customers—recovering sales that would have otherwise walked away.

🤖 3. Built-In Klaviyo & Shopify Flow Automations

Connect inventory directly to your marketing. Automatically push restock events into Klaviyo win-back flows and use Shopify Flow triggers to pause ad spend on sold-out products.

📦 4. Multi-Currency Supplier Orders & Global Tracking

Order from international suppliers (USD, CNY, EUR, GBP) with live currency rates and track purchase order shipments across 2,400+ carriers (DHL, FedEx, YunExpress, 17TRACK).

📊 5. 7-Day Predictive Stockout Forecasting

See exactly which products are projected to run out of stock in the next 7 days based on your actual sales velocity.
