As you grow into larger and more complex defense work, the government stops just checking your prices and starts grading your internal systems. Under the Defense Federal Acquisition Regulation Supplement (DFARS), certain contractors must maintain adequate business systems, and a system judged to have a significant deficiency can lead the government to withhold a percentage of your payments. For a growing firm, that is a direct hit to cash flow.
The six business systems
DoD focuses on six systems (DFARS 242.70 and related clauses):
- Accounting system (the ability to track and allocate costs correctly).
- Estimating system (how you build proposal pricing).
- Purchasing system (how you buy from and flow requirements down to subcontractors).
- Earned value management system (for large, complex programs).
- Material management and accounting system (how you plan and account for materials).
- Property management system (how you control government property in your possession).
Not every contractor is subject to every system, and the clauses attach based on contract type, value, and whether you handle certified cost or pricing data or government property. But as you take on cost-type work, large programs, or government-furnished property, these obligations start to apply.
Why a deficiency hurts: payment withholds
Here is the mechanism that gets attention. If the government determines one of your covered systems has a significant deficiency, the contracting officer can direct a payment withhold on affected contracts, commonly up to a set percentage per deficient system, with a cap when multiple systems are involved. You keep performing, but a slice of your money is held back until you correct the problem and the government accepts your fix. For a small business without deep reserves, that squeeze can be severe.
The integrity angle
Business systems are not just about efficiency. Your estimating and accounting systems are the machinery behind the certifications you make on pricing and billing. A weak estimating system can produce the defective pricing that leads to a Truth in Negotiations Act problem. A weak accounting system can let unallowable costs slip into billings. So system adequacy is quietly connected to your fraud exposure, not just your paperwork.
What to do now
- Know which systems apply to you. Check your contract clauses. As you move into cost-type or larger work, the business system clauses may attach.
- Document your processes. Written policies and consistent practice are what a reviewer looks for. Undocumented but functional is still a finding.
- Fix findings fast. If a deficiency is identified, a prompt, well-documented corrective action plan is your path to releasing any withhold.
- Invest ahead of growth. An adequate accounting and estimating system is what lets you safely pursue the bigger, cost-type awards.
The systems that pass a government review are the same systems that keep you out of a pricing or billing dispute. Build them before you need them. Brick by brick.
FAQ
Do the business system rules apply to small businesses?
They attach based on contract type, dollar thresholds, and whether you handle certified cost or pricing data or government property, not on your size alone. A growing small business taking on cost-type or large defense work can become subject to them.
What is a significant deficiency?
A shortcoming in a system that materially affects the government’s ability to rely on information the system produces. That is the trigger for potential payment withholds.
How much can be withheld?
Withholds are set as a percentage of payments on affected contracts per deficient system, with a cap when multiple systems are deficient. The exact figures are in the DFARS clauses and your contract.
How do I get a withhold released?
Submit a corrective action plan, implement it, and obtain the government’s determination that the deficiency is resolved. Speed and documentation matter.
