Turn your osCMax catalog into feeds that know what sells.

osCMax (short for "open source Commerce Maximized") is a free, open-source e-commerce shopping cart platform built as an extension of osCommerce MS2. Rather than being a from-scratch rewrite, osCMax takes the osCommerce codebase and layers in bug fixes and commonly requested features that were missing from the standard osCommerce distribution, such as gift vouchers, downloadable/virtual products, additional payment gateways, and shipping carrier integrations.

Like osCommerce, osCMax is self-hosted: merchants download the PHP/MySQL application and run it on their own web server rather than using a hosted SaaS storefront. The project has released a few major branches over the years, including the 2.0.x series (closely resembling osCommerce 2.2) and a later 2.5 branch with more extensive internal changes.

• Connect once, no manual exports
• Catalog changes reach your feeds on every sync
• Product Score, 4T, Price War and Broken Size labels on every product
• One source, a tailored feed for each of 200+ channels

Because osCMax is a self-managed, code-level platform, merchants running it often manage product data directly in the database or admin panel with limited built-in tooling for multi-channel selling. Connecting osCMax to Feedance gives you a central place to manage product, inventory, and order data without needing to build custom scripts against the osCommerce/osCMax database schema.

This is especially useful if you sell across multiple channels or marketplaces and need your product feed, stock levels, and order information kept consistent without manual exports or one-off integrations.

Feedance reads three groups of osCMax data. Each one has a job in the feed.

Feedance connects directly to your osCMax store to read and write the data it needs for feed management. Once the connection is authorized, Feedance can retrieve your product catalog and stock information and reflect order updates back into your workflow, all without requiring you to manually export files or build a custom integration.

Because osCMax stores can vary in how they are hosted and customized, Feedance's connection is designed to work with a standard osCMax installation and its underlying store data.

1. 01
   Create or log in to your Feedance account.
2. 02
   Start a new platform connection and select osCMax as your store type.
3. 03
   Enter your osCMax store's connection details as prompted by Feedance.
4. 04
   Authorize the connection so Feedance can access your Products, Inventory, and Orders data.
5. 05
   Confirm the connection and review the initial data sync in your Feedance dashboard.

Once connected, Feedance keeps your osCMax product, inventory, and order data in sync on a regular basis so your feeds stay current. Sync frequency can depend on your plan and store size; if you need near-real-time updates for a fast-moving catalog, check your account settings or reach out to support to confirm the sync interval available to you.

Once osCMax is connected, every channel gets its own feed from the same source, with Feedance labels in custom label fields.

• Keep product titles and descriptions in osCMax clean and consistent, since these fields typically map directly into your feed.
• Maintain accurate stock quantities in osCMax so Feedance can reflect real-time availability and avoid overselling.
• Organize products into clear, well-structured categories to make feed mapping and channel-specific formatting easier.
• Use high-quality, properly sized product images, as image quality often affects how listings perform on downstream channels.
• Periodically audit your osCMax catalog for duplicate or discontinued products so your feed doesn't carry outdated listings.
