Advance Payments (FAR 32.403)(FAR 52.232-12 Clauses) are a type of contract financing the Government provides to contractors to accomplish or to maintain progress on an essential program or contract objectives. It’s rarely used but is sometimes offered to contractors who are unable to start or maintain satisfactory progress on contracts without advance financing from the Government.

Advance Payments MAYBE useful and appropriate for the following: 
- Contracts for experimental, research, or development work with nonprofit educational or research institutions.
