Government contracting is a world of exact rules and unforgiving deadlines. Between Federal Acquisition Regulation (FAR) clauses, Cost Accounting Standards (CAS) nuances and evolving audit expectations, even seasoned leaders can feel stretched.
It can be tougher for smaller teams because they must set rates, track time and price work while preparing for reviews that could halt billing. What are the best companies for government contract consulting services? Eight firms stand out for their practical capabilities, sharper visibility and risk controls that help contractors stay compliant and grow.
1. BOOST
BOOST focuses on the GovCon market and offers outsourced back-office solutions built for contractors. Services cover accounting and payroll, contracts administration, HR and recruiting, and compliance training. The model is designed to plug in cross-functionally, which helps founders and finance heads replace capacity gaps and move faster during growth spurts.
The provider emphasizes hands-on compliance in areas GovCons face daily, including indirect rate structure, cost-volume development and workforce scaling aligned to contract needs. What stands out is the emphasis on small to midsize contractors who want enterprise-grade processes without building a large permanent team.
2. BDO
BDO is a global firm with one of the largest government contracting practices. It’s backed by a Government Contracting Center of Excellence that publishes ongoing guidance and training.
The team supports the full contract life cycle, from market entry and systems selection to audit readiness and disputes, serving both emerging contractors and multinationals. BDO’s public materials highlight coverage across finance, tax, compliance and enterprise systems used in GovCon, which helps clients align operations with federal expectations.
3. FTI Consulting
FTI Consulting brings deep experience in risk mitigation and dispute resolution for government contractors. Practice descriptions outline advisory across FAR and CAS compliance, internal controls, fraud and investigations, cost accounting, damages analysis, and litigation support. This mix is useful when you face a high-stakes audit, accounting challenge, or claims scenario and need senior bench strength that understands legal and financial contours.
4. Cherry Bekaert
Cherry Bekaert’s GovCon practice sits inside a national accounting and advisory platform staffed by advisors with experience in defense contract environments. The firm offers support for business systems, allowability, audit preparation and ongoing compliance, which fits contractors looking for day-to-day controls and review readiness. Its positioning focuses on improving profitability while staying within regulatory bounds — practical for contractors that must defend indirect rates and manage evolving cost policies.
5. Forvis Mazars
Forvis Mazars provides accounting and consulting services across the public sector with a strong emphasis on cybersecurity. The enterprise states that it is an authorized C3PAO and publishes guidance on cybersecurity assessments and readiness, which is vital for defense contractors that must prove compliance under the 32 CFR Part 170 rule. If your priority is closing gaps to NIST 800-171 or preparing for Level 2, this focus can reduce uncertainty and work.
6. Federal Schedules
Federal Schedules is a niche firm dedicated to U.S. General Services Administration (GSA) and Veterans Affairs Schedule consulting. It provides end-to-end assistance, from determining eligibility and strategy to proposal development, award, and post-award management. Contractors who need help with contract maintenance find value in a team that lives in this niche daily.
Longevity also matters — FEDSched notes experience dating back to the 1980s, bringing pattern recognition to negotiations and modifications. It may be a good fit if your near-term goal is to secure a Multiple Award Schedule (MAS) award or expand special item number coverage.
7. Victura Consulting
Victura Consulting focuses on the financial side of government contracting. Its website highlights work on CAS disclosure statements, indirect rate design, and FAR and CAS-aligned contract accounting and billing processes.
This is an advantage for finance chiefs needing hands-on help reworking cost structures or strengthening billing accuracy. The company also offers data analysis and modeling for pricing and margin visibility.
8. Accenture
Accenture is a global technology and consulting provider with a major public sector footprint. The federal and public service materials highlight digital transformation across data, cloud, artificial intelligence, cybersecurity, and legacy modernization. If you are leading a large program with complex technology change or multi-agency dependencies, Accenture’s scale and delivery methods are designed for enterprise-level initiatives.
Our Methodology for Selecting the Top GovCon Consulting Firms
To anchor the selection in real demand, this list looked at signals that matter most to contractors. It evaluated providers based on the following four criteria:
Industry specialization: Preference for teams that dedicate meaningful attention to the government contracting market and understand its rhythms
Proven expertise: Demonstrated fluency in Defense Contract Audit Agency, FAR and CAS requirements, and experience preparing for or supporting audits
Comprehensive services: Providers that can cover accounting, HR, recruiting, contracts and pricing, so contractors do not have to manage many vendors
Scalability and client focus: Ability to support small and midsize firms that often need fractional guidance to mature their systems
The GSA reports that buyers continued to spend through MASs, clearing more than $51.5 billion in sales in 2024. This demand indicator reinforces the value of advisory and compliance support across the sector.
In parallel, the professional, scientific and technical services sector is projected to grow by 10.5% from 2023 to 2033. These numbers highlight the steady need for specialized consulting skills GovCon relies on.
Matching Scope to Strategy
The best consulting partner for government contracts is the one that fits your stage, risk profile and goals. If you need to stand up compliant back-office functions while building a pipeline, a GovCon-exclusive specialist can shorten the distance from award to execution. If you face audits, claims or a controls reset, a dispute-savvy advisor brings structure and focus. If your program hinges on cloud and data modernization, a global systems partner can help you scale.
Whatever an entity needs, these eight firms provide options to grow within the rules and compete with clarity. The next step is to map your gaps, set out the outcome you want and hire to that line.
