You may have noticed the Non-billable checkbox when creating a time entry, expense, or invoice.

This Non-billable feature is useful for entries that you would like to track but not bill your client for. For example, the first document you prepared only took an hour, but you still want that reflected on the invoice so the client knows you did the work and are not charging them. Or, in flat fee case situations, you may want to track your time and expenses but not charge the client for them.

To mark a time/expense entry as non-billable, simply check the non-billable box in the invoice line item.

To add a Non-Billable entry to an existing invoice, select the Edit Invoice button and check the non-billable box in the invoice line item.

The screenshot below shows how these entries will appear on an invoice sent to a client.
