If the SKU (Stock Keeping Unit) does not match between WooCommerce and Square, the inventory sync will not work correctly. Here are some key points to consider:
1. Matching SKUs: The inventory sync relies on matching SKUs between WooCommerce and Square. If the SKUs do not match, the inventory levels will not sync correctly[2].
2. Manual Sync: If you have to sync existing WooCommerce products to existing Square items, you need to have more than just the SKUs perfectly aligned. This includes ensuring that categories, product types, and variation names match exactly[4].
3. Sync Issues: If the SKUs do not match, you may encounter issues with the sync, such as duplicate products or incorrect inventory levels. This can lead to inconsistencies across both platforms[1][4].
4. Troubleshooting: To troubleshoot SKU mismatch issues, ensure that you are using the latest versions of WooCommerce and Square. Check that the product SKUs in both platforms match, and disable any other Square integration plugins that might be causing conflicts[2].
5. System Status Report: If you are still experiencing issues, share your System Status Report and fatal error logs to help identify the problem[2].
By ensuring that SKUs match correctly between WooCommerce and Square, you can avoid common issues with inventory syncing and maintain a consistent product catalog across both platforms.
