Estimated Landed Cost - raising the vendor bill

Hi NS Community,

From SuiteAnswers the process of using the estimated landed cost from creating the estimated landed cost templates to applying into item records and using in PO/IR/VB transactions are clearly documented. However, I would like to know the standard best practice when now clearing the accrued landed cost amount thru the vendor bill to the freight company.

Is it enough to just enter the vendor bill with details as below:

- Freight Vendor

- Landed cost account - entered via expenses subtab in VB

- amount

- other details, e.g. tax, classifications, memo etc.

Or,

Do we really have to use items subtab - noninventory / other charge for resale item and choose a landed cost category in the vendor bill? What is the advantage of doing this over just straight entering the account in the vendor bill?
