Let me guide you about track landed costs with different shipping and supplier vendors, dpic44. I'm always here to support you in any way I can.
I suggest creating an expense account for the inventory and landed cost. Here's how:
1. On the left panel, select + New button and create a Bill.
2. Under Vendor dropdown section, choose the account and from the Category details, choose the account created for inventory and landed cost.
3.. Enter an amount for the inventory and zero for the landed cost since you are not yet sure of the exact amount.
4. Select, Save and close.
5. Then, you can update once the amount for landed cost is already shipped.
As an alternative, you have the option to create a journal entry using the same account. However, I highly suggest seeking help from your accountant for more precise guidance.
