Date stamp the front page of all contractor's construction invoices immediately upon receipt.
If the invoice was faxed directly to BLM, make sure the received date appears on the faxed invoice. If for any reason this payment process is delayed, the CO must be notified immediately. The time between contractor notification and contractor compliance is added to the 14-day payment period. The 14-day payment period does not start over when the extension is made. Other actions may include returning the invoice within seven days of its receipt for correction, or a CO retention taken on the contract payment.
