There are two ways to raise an invoice for a billable expense. You can do this directly from the expense or create an invoice and include the unbilled expense.

**To create an invoice from the expense:**

*   Go to the **Purchases** module on the left sidebar and click **Expenses.**
    
*   Select the expense you have marked as billable and click the **Convert To Invoice** button.

*   A new Invoice will be created with the expense details.
    
*   Enter other required details and click **Save and Send** to send the billed expense as an invoice to your customer.
    

**To add an unbilled expense to an invoice:**

*   Go to the **Sales** module on the left sidebar and click **Invoices.**
    
*   Click **\+ New** in the top right corner to create a new invoice.
    
*   Select the customer for whom you recorded the billable expense.
    
*   The unbilled expense associated with the customer you have selected will be displayed below the item table.
    
*   Click the **unbilled expense** to add it to the invoice.
