Reimbursable Expenses

Reimbursable Expenses

We being freight forwards pay multiple expenses on behalf of customers and charge them on actual. like Port charges, THC, Inspection and some time even Custom duties.
How to record these reimbursable expenses, if the same was billed to us through a vendor bill.
Another problem is Reimbursable expenses are not actual expenses nor they are income for company.
We can not add them from items as they restrict items with only income and COS.
Any help
