You can add more items to one expense. By default, the expense includes just one item but if you need more, just click ‘Add item’:
On the expenses list, each item will be displayed on a separate line:
If you mark an expense as billable and attach it to client/project, all its items will be automatically linked to this specific client/project.
In case you apply an % admin fee, it will be applied to all the items, but if you use a fixed admin fee it will only be applied to the first item. The same goes with Expense Attachment – if you include an expense to an invoice (bill expense), its receipt will be added to the invoice which has the first item of that expense.
