Configure incoming eBay orders to flow into Odoo Sales Orders with automatic stock pull and updates IMPORTANT DETAILS: - Odoo version: 19.0 (live server, already deployed) - I have thousands of existing eBay listings — bulk SKU mapping experience is essential - Both eBay seller accounts must be connected to one Odoo instance - Stock must sync automatically in both directions REQUIREMENTS: - Proven experience with Odoo eBay connector modules (please name which one you've used) - Experience handling large product catalogs (1,000+ SKUs) - Familiarity with Odoo Sales Orders, Inventory, and multichannel setup - Ability to provide a fixed or hourly quote with a clear completion date - Please share examples of similar past projects IN YOUR PROPOSAL, PLEASE ANSWER: 1.
