Barcode Implementation in Odoo 13

I want to implement barcode module. I have Odoo 13 Enterprise. I already have the barcode module installed. But there are some issues:

1. POS doesn't scan all products (sometimes shows read error, wrong SKU, doesn't read weight properly)
2. When creating a sales order, it needs to scan and apply the weight and SKU properly (but it will take the price from the pricelist in Odoo)
3. Implement barcodes in Inventory, transfers, purchase orders, Inventory adjustments, etc.
4. It needs to work properly in all core modules.

Thanks
