Federal Billing, Built Right
Accounting and invoicing support built for federal contracts, grants, and audit-ready growth.
Keep Your Contracts Funded and Your Cash Flow Moving
Federal funding is only valuable when your business can bill accurately, collect on time, and support every dollar with the right records. For contractors and grant-funded organizations, invoicing is not just an administrative step — it is where accounting, compliance, cash flow, and contract performance come together.
Peter Witts CPA PC helps clients manage the financial details behind federal billing, from cost tracking and indirect rate application to invoice support, reconciliations, and documentation packages. Whether you are billing through WAWF, IPP, PMS, or another agency platform, we help ensure your invoices are connected to clean accounting records and supported by a clear financial trail.
Our goal is to help your business maintain funding continuity, reduce billing delays, and manage federal awards with greater confidence.
Why Federal Contract Accounting Requires More Than Standard Bookkeeping
Federal contract accounting is different from commercial bookkeeping because every cost, invoice, and billing decision may need to be supported under federal rules and agency expectations.
Your accounting system must be able to show how funds are spent, how costs are classified, how labor is charged, how indirect rates are applied, and how invoices connect back to the general ledger.
Depending on your contract or award structure, your records may need to support:
- FAR Part 31 cost allowability requirements
- CAS consistency and cost accumulation expectations
- DFARS business system and internal control requirements
- OMB Uniform Guidance for grant-funded work
- DCAA, DCMA, NIH, DOE, DoD, or other agency review
- Traceability from timesheets, expenses, and ledgers to invoices and reports
Peter Witts CPA PC helps translate these requirements into accounting and billing processes your team can use every month — not just when an audit or agency review is underway.
Accounting System Design & Configuration
A strong billing process starts with a strong accounting system. If costs are not properly classified, tracked, and reconciled from the beginning, invoicing becomes harder to support later.
Peter Witts CPA PC helps design and configure accounting systems that support federal billing, contract performance, and audit readiness.
This may include:
- Separating direct, indirect, and unallowable costs
- Structuring fringe, overhead, and G&A cost pools
- Tracking costs by contract, CLIN, task, project, grant, or funding increment
- Integrating labor distribution, purchasing, subcontractor costs, and billing workflows
- Creating reports that support leadership, invoice preparation, and agency review
- Maintaining audit trails between the general ledger, project ledgers, and invoice support
We work with platforms such as QuickBooks, Unanet, Deltek Costpoint, and other systems based on your contract mix, award complexity, and internal team capacity.
Contract Billing and Invoicing Management
Federal invoicing requires more than entering numbers into a billing portal. Each invoice must reflect the contract terms, approved funding, allowable costs, indirect rate structure, labor support, and required documentation.
Peter Witts CPA PC helps manage invoicing processes that are accurate, supported, and aligned with federal expectations.
Our support may include:
- Invoice preparation for WAWF, IPP, PMS, and other agency systems
- Cost-reimbursable, time-and-materials, fixed-price, and grant billing support
- Funding reconciliation against obligations, modifications, and remaining balances
- Labor, subcontractor, materials, travel, and other direct cost support
- Indirect rate application and review
- Documentation packages for agency or auditor review
- Invoice-to-ledger tie-outs and billing schedule reconciliation
The result is a billing process designed to protect cash flow, reduce rework, and give your team confidence that each invoice is backed by the right records.
Indirect Rate Tracking & Billing Accuracy
Indirect rates have a direct impact on billing accuracy, cash flow, and cost recovery. When rates are not monitored regularly, small differences can accumulate into larger underbillings, overbillings, reconciliation issues, or audit concerns.
Peter Witts CPA PC helps contractors and federally funded organizations track, apply, and reconcile indirect rates as part of the monthly accounting and billing process.
Our support may include:
- Provisional billing rate calculations
- Fringe, overhead, and G&A rate monitoring
- Monthly actual-to-provisional rate comparisons
- Underbilling and overbilling analysis
- Forward-looking rate impact review
- Support for ICE, NICRA, or indirect cost submissions when applicable
- Reconciliation between rate schedules, ledgers, invoices, and supporting reports
By integrating rate management into regular financial operations, we help clients avoid year-end surprises and make better decisions about pricing, billing, and growth.
Revenue Recognition & Cost Reconciliation
Federal contracts often require careful coordination between revenue recognition, billing, cost tracking, and financial reporting. Different contract types create different accounting considerations, and leadership needs reports that reflect both compliance and business performance.
Peter Witts CPA PC helps align revenue recognition and cost reconciliation practices with the realities of federal funding.
Our support may include:
- Revenue recognition for fixed-price, cost-reimbursable, and time-and-materials contracts
- Billing and cost reconciliation by contract, project, CLIN, or funding source
- Unbilled receivables and revenue-in-excess-of-billings review
- Progress payment, advance, and retainage tracking
- General ledger-to-invoice reconciliation
- Budget-to-actual and cost-to-complete reporting
- Review of billing accuracy against contract terms and financial records
- This gives leadership a clearer view of contract performance while helping ensure that reported revenue, billed costs, and supporting records remain aligned.
We empower our clients to grow with confidence by delivering high-quality, customized financial services that meet the exacting standards of the DCAA, NIH, DOE, and other federal agencies.
Frequently Asked Questions
What is “government contract accounting,” and how is it different from regular accounting?
Government contract accounting involves following specific federal rules, standards, and compliance requirements (e.g. cost allowability, audit readiness, indirect rates, DCAA standards). Unlike general accounting, your financial systems need to withstand audits, cost proposals, and strict oversight. We structure your accounting and reporting so you stay compliant and reduce risk.Do I need to worry about DCAA audit compliance?
If you hold or are bidding on U.S. federal contracts (especially cost-reimbursable, time & materials, or fixed price with cost elements), the Defense Contract Audit Agency (DCAA) may audit your accounting systems. We can help you build or review systems so you pass audits when they arrive.Can you help with indirect cost rates, cost proposals, and incurred cost submissions?
Yes — we support designing indirect cost rate structures, preparing cost proposals, and submitting incurred cost reports. These are critical tasks in government contracting, and we ensure your supporting records align with regulatory expectations.How much experience do you have in the federal contracting space?
Peter Witts CPA PC has over 36 years of experience in government contract accounting, including first-hand DCAA knowledge. We’ve worked with clients across DoD, NIH, DOE, and other agencies, helping them navigate the compliance landscape.What kind of businesses or projects do you work with?
We work primarily with companies engaged in federal contracts or grants (especially research, development, support services). If your business isn’t in that space, we’ll help you determine whether our services are the right fit or recommend alternatives.How do I get started with you?
You can schedule a free consultation via our website. During that call we’ll explore your current standing, challenges, and needs, and map out how we might support you. (Then we’ll formalize scope, pricing, and next steps.)What should I provide for an initial assessment?
Financial statements, accounting policies, prior audits (if any), contracts and grant agreements, cost accounting structure, payroll records, indirect cost allocations, and any compliance documents. We’ll review what you have, identify gaps, and propose next steps.How often will we interact / how do you deliver services?
That depends on the scope. For outsourced accounting, we could work on a monthly or quarterly basis. For compliance or audits, we may engage more intensively. We'll agree up front on communication frequency, deliverables, and review cycles.What are your fees or how is billing handled?
Our fees are fixed monthly fees and depend on the complexity and scope of your work — number of contracts, volume of accounting entries, compliance risk, etc. We’ll provide a proposal after our initial assessment. We only work on an hourly basis for audit support services for audits relating to government contracts or grants conducted by government agencies or outside CPA firms.What if my business is outside of your specialization—can you still help?
At Peter Witts CPA PC, we focus exclusively on our core strength: federal contract and grant compliance. We serve businesses operating within the government contracts and grants space, offering specialized outsourced accounting and tax services tailored to the unique requirements of this industry. This is our sole focus — we don’t try to be everything to everyone. Our expertise is deep, not broad, and it’s dedicated to helping government contractors navigate complex compliance and maximize their opportunities.What happens if there's a federal audit or examination?
We support audit responses, documentation requests, and work with your team to ensure you respond properly. Because we build systems with compliance in mind, we aim to minimize surprises and help you maintain defensible records.How do you keep up with changing federal regulations and compliance standards?
