Contractor Guidance for Your Bid
Invoice submission is your lifeline to payment. Get the format right the first time. Use a template provided by the contracting officer. Keep copies of every invoice with proof of submission. If you are late billing, you lose interest—there is no grace period. Government pays on Net 30-45.
