The Open-Source Playbook to Eliminate Overselling

Selling across multiple channels like your website, social media, and marketplaces? You're likely bleeding revenue and trust. When a sale on one channel doesn't instantly update inventory everywhere, you oversell products. This leads to a cascade of disasters: cancelled orders, furious customers, negative reviews, and wasted support hours, crippling your brand's reputation and growth.

The Open-Source Powerhouse stack gives you complete control over your e-commerce operations. By leveraging a suite of powerful, free-to-use platforms, you can build a custom Inventory Management System that eradicates overselling. Odoo serves as your single source of truth for all inventory and business data. It seamlessly integrates with your WooCommerce storefront for real-time stock updates and Mautic for intelligent marketing automation, all while eliminating expensive recurring software fees.

  • Achieve 100% real-time inventory accuracy across all sales channels.
  • Completely eliminate overselling and the resulting cancelled orders.
  • Dramatically reduce customer support tickets related to stock issues.
  • Enhance customer satisfaction and protect your brand's reputation.
  • Gain a unified view of your customers and operations for smarter decision-making.

Integration Logic

  • Odoo-Commerce API Gateway

    This integration acts as a central hub for data exchange between Odoo, WooCommerce, and Mautic. 1. **WooCommerce to Odoo**: When a new order is placed in WooCommerce, a webhook triggers the gateway to create a corresponding Sales Order and Customer record in Odoo. Inventory levels are reserved in Odoo. 2. **Odoo to WooCommerce**: When product information (e.g., stock quantity, price) is updated in Odoo, a scheduled task in the gateway pushes these changes to the corresponding products in WooCommerce. Similarly, when an order is marked as fulfilled or shipped in Odoo, the gateway updates the order status in WooCommerce. 3. **WooCommerce to Mautic**: New customers and completed orders in WooCommerce trigger the gateway to create or update contacts in Mautic. Contacts can be added to specific segments (e.g., 'New Buyers') and enrolled in marketing campaigns (e.g., 'Welcome Series'). 4. **Odoo to Mautic**: Customer data from Odoo, such as lifetime value or specific order history, can be synced to custom fields in Mautic via the gateway. This enables highly targeted marketing segmentation and personalization based on ERP data.
