A Legacy of Protection
Our Legacy of Government Contract Accounting Expertise
At Peter Witts CPA PC, our story began not in theory, but in the real-world challenges of government auditing. After years working inside the Defense Contract Audit Agency (DCAA), Peter Witts saw a clear and urgent need: companies were losing contracts, mismanaging funds, and falling short of compliance—not because they lacked potential, but because they lacked proper financial guidance.
So in 2000, he made the decision to move to the other side of the table. From that point forward, our firm has been singularly focused on helping businesses navigate the complex world of government contract accounting with clarity, compliance, and confidence.
What began as a solo practice has grown into a respected and specialized CPA firm serving government contractors and federally funded businesses nationwide. We’ve helped organizations—from first-time SBIR grantees to multi-award defense contractors—build sustainable, audit-ready financial systems that withstand scrutiny and support growth.
Our Promise to Every Client:
- We serve with integrity. Compliance and transparency come first—every time.
- We deliver specialized insight. Our team knows the unique demands of federal grant and contract funding.
- We tailor our support. No two contractors are the same; your accounting solution shouldn't be either.
- We grow with you.
As your business scales, our strategies evolve to support more complex requirements.
