Odoo shipping

I am looking for a system that can meet our shipping needs.

We are working in ODOO 18 Enterprise SH

System Requirements

1. Carrier Support – Must support UPS and FedEx; DHL and USPS are a bonus.
2. Own Account Shipping – Ability to ship using the company’s UPS account.
3. Third-Party/Customer Accounts – Ability to ship using customer or third-party accounts.
4. Custom Box Dimensions – Must allow entry of custom box sizes.
5. Multi-Box Orders – Must support shipping multiple boxes for a single order.

System Enhancements

1. Import Data from Sales Orders – Automatically pull information from Odoo sales orders, including:
   • Shipping address
   • Shipping type
   • Box dimensions
   • Weight from scale
   • PO number
   • SO number
   • Customer shipper account
2. Update Odoo with Shipment Info – Automatically update Odoo with shipment details, such as tracking numbers.

S/O > Shipment process:

|1|Create Quote / Sales Order & Add Shipping Method|Customer info, items, quantities, PO number, select carrier (UPS/FedEx/DHL/USPS), choose company/customer/3rd-party account|

|2|Pick Items|Confirm correct items and quantities|

|3|Pack in Custom Boxes|Record box dimensions & weight from scale, multiple boxes per order supported|

|4|Select Carrier, Get Rate & Record in Odoo|Enter box dims, weight, and address; obtain shipping rate; add rate as a line item on SO|

Nothing I have found can do these things. This feels like a very standard process however our integration team is at a loss.

I can't believe I am saying this but Quickbooks has a better shipping integration than Odoo... and I HATE QB, I can't wait to be out of QB into Odoo....but I cant transition without getting shipping figured out.
