The Odoo 19 release brings new built-in functionality for integration with Google Merchant Center (GMC). It allows generating a basic product feed and sending it to GMC for advertising campaigns and product display in Google Shopping.
Manual
Activation
The standard eCommerce app must be installed in order to create a data feed. Go to the Website settings, then to the Tracking and SEO section, and activate the Google Merchant Center option.
Settings
After activation, the list of data feeds becomes available under Website - Configuration - eCommerce - Product Feeds menu.
The built-in Odoo 19 functionality for generating a Google Merchant Center feed, in addition to specifying the feed name, allows configuring the following parameters:
Website
Pricelist
Language
eCommerce Product Category
The native Google Shopping feed generation logic in Odoo 19.0 has a limitation on the number of products included in the data feed — up to 6000 products. When this limit is exceeded, system administrators receive a corresponding notification.

Feed Data Completeness
Product feeds for Google Shopping in Odoo 19.0 include only essential information, covering the basic product attributes.
Solutions from Garazd Creation allow you to provide more detailed product specifications to Google Merchant Center, including technical and marketing features, custom labels and numbers.
Product Filtering
The Odoo 19 solution allows filtering products only by eCommerce categories.
Modules from Garazd Creation provide the flexibility to apply any Odoo filters — from product attributes to stock levels. This makes it possible to generate separate feeds for different segments, markets, or campaigns.
Stock Locations
Unlike the built-in functionality of Odoo, solutions from Garazd Creation allow selecting specific warehouses or stock locations to be used when calculating product availability and stock status. Additionally, they provide the option to define a status for out-of-stock products.
Feed Limitations
Odoo 19 enforces a limit of 6000 products per feed. In contrast, solutions from Garazd Creation support the generation of significantly larger data feeds. This is achieved with a dedicated Product Data Feed Cache module, which generates feeds in parts in the background, thereby reducing the system load. The cached feed is delivered instantly when requested by Google Merchant Center.
Summary
The built-in functionality in Odoo 19.0 for generating a GMC feed provides a simple solution for basic product export to Google Merchant Center. However, if a business actively uses Google advertising tools and requires full control over feed data, the professional solutions from Garazd Creation, such as Odoo Google Merchant Center Feeds and Odoo Google Shopping Professional deliver maximum capabilities and flexibility.
