Hi,

Managing inventory in Odoo for a small retail store with both online and offline sales can be tricky, especially when trying to avoid double-counting stock. To keep things in sync, it's best to use Odoo's Point of Sale (POS) for in-store sales and the Sales module for online orders, ensuring both are linked to the Inventory module for real-time stock updates. Barcode scanning helps with accuracy, and regular stocktaking (physical inventory counts) is essential to correct any discrepancies. Some businesses even create custom Odoo setups for more specific needs, but the key is to automate stock movements and reconcile regularly to prevent errors.

Hope it helps.

We handle this by splitting stock into two locations: one for POS (that's the original way odoo predicted to activr/offline/personal sales happen in odoo), one for Online (you can try running your site and connecting website to sales, or using sales by your employees or giving portal user to your customers, etc. ). Each channel reduces only its own location (inventory operations and route settings). Then a scheduled action (or connector if you use Shopify/WooCommerce) keeps both synced with the main warehouse. This way POS offline mode won’t double‑count, and you can track each channel cleanly. read and watch odoo's documentations and toturials for better examples.
