Warning: Manually entered time billing invoices are not included in many reports

You can also enter activities on a time billing invoice manually, but no activity slip records will exist for the activities you include. Many time billing reports are based upon activity slip records, so we recommend you enter activities automatically using the procedure outlined above.
