E-commerce Stock Notifications

Bring customers back when products restock

Stock Notification Feature

Maximize your revenue by capturing interest even when inventory runs out. Allow customers to subscribe to back-in-stock notifications directly from the product page and automatically notify them when stock is replenished.

🌐 Unified Stock Configuration

ONE global setting for consistent stock logic

Global Stock Calculation Method

This module uses ONE unified setting that applies to ALL stock features:
✅ Stock notification triggers (when to send "back in stock" emails)
✅ Add to cart disabling (when to block purchases)
✅ Stock status displays (out of stock badges)

Actual Quantity Setting

📦 Actual Quantity (Default)

Active in all triggers: Uses physical On Hand stock only. This is the standard setting that ensures notifications and cart disabling happen only when goods have physically entered your warehouse.

Forecasted Quantity Setting

📈 Forecasted Quantity

Active in all triggers: Uses Forecasted stock (On Hand + Incoming - Outgoing). Perfect for notifying customers and enabling purchases as soon as a Purchase Order is confirmed, even before goods arrive.

Available Quantity Setting

✅ Available Quantity (Strict)

Active in all triggers: Checks Free to Use stock (On Hand - Reserved). Ensures you never notify customers or allow purchases for stock that is technically on hand but already reserved for other pending orders. Safest for e-commerce.

Data Management Setting

Notification Data Management

Preserve Sent Notifications: Check this to keep a history of every notification sent. If unchecked (default), processed notifications are automatically deleted to maintain a lean, high-performance database.

Backend Configuration Menu

Easily access all notification settings and records from the Sales > Configuration > Stock Notifications menu in the backend.

Seamless User Experience

Clear communication with your customers

Out of Stock Badge

Clear Status Indicators: When "Disable add to cart" is active, products automatically display a clear "Out of Stock" badge in the catalog, managing customer expectations before they even click.

Product Page Disabled Cart

Smart Product Pages: The "Add to Cart" button is automatically disabled and quantity selection is locked. A prominent "NOTIFY WHEN AVAILABLE" button appears, inviting the customer to subscribe.

Subscription Confirmation

Instant Feedback: Upon subscribing, customers receive immediate confirmation that they will be notified, providing assurance and improving the user experience.

Notification with Ordering Allowed

Hybrid Mode: If "Disable add to cart" is off, you can still offer stock notifications while allowing purchases (e.g., for backorders). The "NOTIFY WHEN AVAILABLE" button appears alongside the active "Add to Cart" button.

Guest & Incognito Support

Guest User Subscription

Capture Every Lead: Users don't need to be logged in to subscribe. Incognito or guest visitors are presented with an email input field, ensuring you capture every potential sale.

🧠 Smart Stock Logic

We handle the complexity so you don't have to

How It Works Technical Deep-Dive:

Odoo's default behavior is to hide out-of-stock products completely or remove the ability to interact with them. This loses you valuable leads!

Our Smart Fix:

  • We force "Allow Out of Stock Orders" in the background.
  • Our Javascript intercepts the "Add to Cart" event.
  • If stock is 0, we block the purchase and show the "Notify Me" button.
  • This guarantees your customers can ALWAYS subscribe to alerts.
Zero Configuration

Just install and it works.

Customer Portal Control

Self-service management for your users

My Account Menu

Integrated Navigation: A dedicated "My Stock Alerts" link is automatically added to the customer's portal account menu for easy access.

My Stock Alerts List

Comprehensive Dashboard: Customers can view their active subscriptions, see product details and "Requested On" dates, and easily manage or cancel alerts from a clean, mobile-responsive interface.

Powerful Backend Management

Full visibility into demand

Notifications List

Request Tracking: Monitor all stock requests in real-time. The list view provides a quick overview of products, customers, and current status (e.g., Pending, Sent).

Notification Detail View

Detailed Control: Drill down into individual requests. Administrators can view full details including user email and requested date. You can even manually trigger notifications using the "Send notification Now" button for immediate engagement.

🛡️ Anti-Spam Security Features

Enterprise-grade rate limiting and fairness algorithms

Production-Safe Notification System

Advanced anti-spam protection prevents email server overload when hundreds of users are waiting for the same product. Intelligent rate limiting with FIFO fairness ensures no user is left behind.

Product-Level Rate Limiting

Prevents email server overload:

  • Max Notifications per Product: 100 per cron cycle (default)
  • FIFO Fairness Algorithm: First-come, first-served processing
  • Attempt Tracking: Records all notification attempts for analysis

✅ Prevents burst sending when 500+ users wait for same product
✅ Ensures fair distribution across cron cycles

Notification Attempt Counter

Enhanced monitoring and analytics:

  • Field: notification_attempt_count on stock notification model
  • Tracks: How many times system tried to send each notification
  • Use Cases: Identify popular products, analyze demand patterns

✅ Business intelligence for inventory planning
✅ Identify products causing rate limit hits
✅ Optimize stock replenishment strategy

Configuration Parameters

Customize rate limiting via Settings > Technical > Parameters > System Parameters:

Parameter Key Default Value Description
ecommerce_stock_notification.max_notifications_per_product 100 Maximum emails sent per product per cron execution

Tip: Lower this value if you have limited email server capacity. Increase for high-demand scenarios with fast restocking cycles.

FIFO Fairness Algorithm Implementation

How it works:

  1. Grouping: Notifications are grouped by product_template_id
  2. Sorting: Within each group, sorted by create_date (earliest first)
  3. Limiting: Only first N notifications per product are processed
  4. Tracking: All attempts are counted, even rate-limited ones
  5. Retry: Unprocessed notifications remain in queue for next cron cycle

Result: Even with 1000 waiting users, system sends only 100 emails per cycle (configurable), ensuring fair distribution and preventing email server overload.

Real-World Spam Prevention Scenarios

Scenario 1: Viral Product Launch

Problem: 500 users subscribed to notifications for limited-edition product.
Without Protection: 500 emails sent instantly → email server throttled/blacklisted.
With Rate Limiting: 100 emails per cycle, 5 cycles needed, all users notified fairly.

Scenario 2: Stock Fluctuation

Problem: Product stock updates multiple times per day (manual adjustments, warehouse sync).
Without Protection: Same users get multiple notifications per day.
With Rate Limiting: Processed notifications are archived/deleted, preventing duplicates.

Enhanced Logging

Monitor anti-spam protection in real-time:

  • _logger.info("Rate limiting active for product X: found Y notifications, will process Z")
  • _logger.info("Successfully sent email to X, attempt count: Y")
  • _logger.info("Total notifications sent in this cycle: X")

Check Odoo logs to verify rate limiting is working correctly and adjust parameters as needed.

⚠️ IMPORTANT CONFIGURATION REQUIREMENT

PLEASE READ CAREFULLY: MANUAL CONFIGURATION REQUIRED

This module relies on the website_sale_stock core functionality. If you have been using Odoo with the "Continue Selling" option DISABLED (which is the default behavior), YOU MUST MANUALLY UPDATE YOUR PRODUCTS.

If a product is set to "Show as Out of Stock" (default Odoo behavior when stock is 0), Odoo's core logic will completely hide the "Add to Cart" button and prevent this module from verifying stock or showing the "Notify Me" button. This is NOT a defect of this module but a core Odoo stock prevention mechanism.

1. Global Setting (Inventory Defaults):

Inventory Defaults Setting

2. Product Level Setting (Sales Tab):

Product Stock Configuration

ACTION REQUIRED:

You must enable "Continue selling when out-of-stock" for your products. You can do this:

  • Via GUI: Go to Product > Sales Tab > Out-of-Stock > Select "Continue selling when out-of-stock".
  • Via Database/Import: Update the allow_out_of_stock_order field to True for all product templates.

Note: We have removed the automatic overwrite of this field to prevent data loss or unwanted configuration changes. You are responsible for ensuring this configuration is correct.
