A Form 9 is not just an admin document. It's the customer's purchase request and funding signal to contracting. Learn where to look first, what the fields mean, and how to spot problems before they become yours.
Before you can buy anything, someone has to ask for it. That request — and the money behind it — starts with the Form 9.
The AF Form 9, Request for Purchase, is how your customer tells contracting what they need and how they're paying for it. It's a funding document — the package that commits money to a requirement and kicks off the acquisition process. No Form 9 (or equivalent PR), no buy.
In the Air Force, DEAMS generates the Form 9. Other agencies use different formats — some use a PR&C (Purchase Request and Commitment) or other service-specific documents. The fields are roughly the same everywhere. As long as you've got certified funding, you're ready to press forward with your requirement. If you understand the Form 9, you can read any purchase request.
When a Form 9 lands on your desk, there are only a few areas where you need to be critical in your review. The rest can typically be changed later in your contract writing system. Two areas tell you 80% of what you need to know:
This is just my opinion (as of this training, March 2026) — but simpler is better on the Form 9. You can absolutely work with a Form 9 structured in other ways, and plenty of COs do. But here's why I prefer fewer CLINs up front:
When finance builds the Form 9 in DEAMS, they sometimes break the requirement into multiple line items. For a construction project, you might see separate lines for plumbing, electrical, concrete, demolition, and painting. That feels organized, but it creates a problem downstream.
The quantity and unit of issue determine how the contractor bills you and how deliverables get structured. That's why they matter. It's not just about counting — it's about shaping the payment schedule and delivery milestones for the entire contract.
The accounting classification line looks intimidating. You don't need to memorize the whole thing. You need three pieces:
Check the Form 9 Trainer tab to see these on a real form, and scroll down for side-by-side LOA examples.
Click the highlighted sections on the form to see notes. The sections with a red left border are the ones that matter most.
These are illustrative examples. Exact LOA structure varies by organization and finance system. For a CO, the key is the first three pieces: agency, appropriation type, and fiscal year.
There's not much written specifically about the Form 9 itself. But if you want to understand the money behind it — appropriations law, fiscal policy, and the rules that govern how the government spends — these are the places to go.
