SBIR/STTR funding can open the door to larger federal opportunities.
After Phase I or Phase II, a company may begin pursuing follow-on contracts, prototype agreements, DoD opportunities, agency-funded development work, or Phase III commercialization paths.
That transition is exciting.
It is also a major accounting shift.
A company that managed a grant or early SBIR/STTR award may now need to prepare for contract clauses, invoicing rules, indirect rate support, DCAA expectations, cost-reimbursable accounting, fixed-price risk, timekeeping, labor distribution, and stronger cash flow controls.
At Peter Witts CPA PC, we help SBIR/STTR companies prepare for federal contract growth by strengthening accounting system adequacy, indirect rates, timekeeping, invoicing support, cost controls, and cash flow planning before contract performance begins.
Why the First Federal Contract Changes the Accounting Conversation
SBIR/STTR companies often begin with research funding.
Federal contracting can bring a different level of financial responsibility.
The company may need to support:
- Contract pricing
- Cost proposals
- Labor categories
- Timekeeping
- Labor distribution
- Direct and indirect cost separation
- Indirect rate schedules
- Invoices or vouchers
- DCAA accounting system questions
- Allowable cost support
- Subcontractor costs
- Cost transfers
- Unallowable cost treatment
- Cash flow forecasting
- Closeout requirements
The accounting system that worked for basic bookkeeping may not be enough for federal contract performance.
Start With the Contract Type
The first financial question is contract type.
A federal contract may be:
- Firm-fixed-price
- Cost-reimbursable
- Cost-plus-fixed-fee
- Time-and-materials
- Labor-hour
- Milestone-based
- Indefinite delivery / indefinite quantity
- Task-order based
- Hybrid
Each contract type creates different accounting, invoicing, pricing, and cash flow responsibilities.
Before signing or bidding, ask:
- How will the company be paid?
- What costs must be tracked?
- What records support payment?
- Who carries cost overrun risk?
- Are indirect rates involved?
- Are invoices based on costs, milestones, hours, or deliverables?
- Is DCAA likely to review the accounting system?
- What closeout records will be required?
A contract should not be treated like a grant simply because the company has federal funding experience.
Understand Cost-Reimbursable Contracts
Cost-reimbursable contracts require strong actual cost tracking.
FAR explains that cost-reimbursement contracts provide for payment of allowable incurred costs to the extent prescribed in the contract.
That means the company must be ready to show:
- Costs were incurred
- Costs were allowable
- Costs were allocable to the contract
- Costs were reasonable
- Costs were recorded properly
- Costs were supported by documentation
- Costs were within contract terms
- Indirect rates were calculated correctly
- Invoices or vouchers were supported
For SBIR/STTR companies moving into DoD Phase II or follow-on contracting, this can be a major change.
SBIR.gov notes that cost-reimbursable contracts are frequently used by DoD with Phase II SBIR awards.
Prepare for the Allowable Cost and Payment Clause
Cost-reimbursable contracts often involve FAR 52.216-7, Allowable Cost and Payment.
That clause says the government makes payments as work progresses in amounts determined allowable by the contracting officer under FAR Subpart 31.2 and the contract terms.
In practical terms, the company should be ready to support payment requests with:
- General ledger detail
- Payroll records
- Timesheets
- Labor distribution reports
- Vendor invoices
- Consultant invoices
- Subcontractor invoices
- Indirect rate schedules
- Proof of payment, where required
- Unallowable cost exclusions
- Budget and funding limit tracking
The invoice is not just a request for payment. It is a claim supported by accounting records.
Understand Fixed-Price Contract Risk
Fixed-price contracts can feel simpler because the company is paid based on agreed pricing, milestones, deliverables, or contract terms rather than actual reimbursable costs.
But fixed-price contracts create a different risk.
FAR explains that contract types range from firm-fixed-price, where the contractor has full responsibility for performance costs and resulting profit or loss, to cost-plus-fixed-fee, where the contractor has minimal responsibility for performance costs and a fixed negotiated fee.
For SBIR/STTR companies, this means a fixed-price contract can become financially risky if costs are underestimated.
Before accepting or pricing fixed-price work, review:
- Labor assumptions
- Technical risk
- Materials and testing costs
- Subcontractor pricing
- Schedule risk
- Indirect costs
- Cash flow timing
- Payment milestones
- Acceptance criteria
- Warranty or rework risk
- Change order process
A fixed-price contract may not require the same cost reimbursement process, but the company still needs cost visibility to avoid losing money.
Do Not Assume Grant Accounting Is Enough
A grant accounting setup may track budget categories, drawdowns, and financial reports.
A federal contract may require more detailed job costing, invoicing support, contract clauses, indirect rate calculations, and DCAA readiness.
The company may need to strengthen:
- Contract project codes
- Cost objectives
- Direct labor tracking
- Timekeeping
- Labor distribution
- Indirect cost pools
- Allocation bases
- Unallowable cost accounts
- Billing support
- Funding ceiling tracking
- Contract modification tracking
- Subcontractor management
- Closeout procedures
The transition from awardee to contractor should trigger an accounting system review.
Review Accounting System Adequacy
DCAA’s pre-award accounting system adequacy checklist is used by auditors in a pre-award accounting system survey to understand how a company’s system is designed to meet accounting system criteria.
The checklist is especially relevant for contractors new to government contracting with cost-reimbursement contracts or contractors receiving progress payments based on cost.
A contract-ready accounting system should support:
- Segregation of direct costs by contract
- Indirect cost identification
- Unallowable cost identification and exclusion
- Timekeeping
- Labor distribution
- Payroll reconciliation
- Cost accumulation by contract line item or cost objective
- General ledger control
- Interim billing support
- Indirect rate calculations
- Contract funding limit tracking
- Reliable monthly reporting
Accounting software alone is not enough. The system design and procedures matter.
Set Up Contract Cost Objectives
Each contract should have its own cost objective.
A cost objective may be a contract, task order, contract line item, work breakdown structure, project, or other final cost destination.
Set up project codes for:
- The federal contract
- Each task order, if applicable
- Each contract line item, if needed
- Subcontractor work
- Internal R&D
- Commercial work
- General and administrative activity
- Unallowable costs
The company should be able to show which costs belong to the contract and which do not.
Prepare Timekeeping Before Work Begins
Timekeeping is one of the most important controls for federal contract work.
SBIR.gov states that a DCAA-compliant timekeeping system is critical when performing cost-reimbursement type contracts, including most SBIR Phase II contracts.
A contract-ready timekeeping process should show:
- Employee name
- Date worked
- Hours worked
- Contract or project code
- Task or labor category, if needed
- Direct contract labor
- Indirect labor
- Non-contract labor
- Employee certification
- Supervisor approval
- Corrections or adjustments
Employees should begin using the correct timekeeping codes before contract work begins, not after the first invoice is due.
Review Labor Distribution
Labor distribution connects timekeeping to payroll and contract costs.
A contract-ready labor distribution report should show:
- Pay period
- Employee
- Hours by contract or project
- Direct labor cost
- Indirect labor cost
- Non-contract labor
- Labor category, if needed
- Fringe allocation
- Payroll reconciliation
- General ledger posting
- Invoice support
If payroll cannot be traced from timesheets to contract cost records, invoicing and DCAA readiness may become difficult.
Review Labor Categories and Personnel Assumptions
Federal contracts may include specific labor categories, key personnel, or staffing assumptions.
Before performance begins, review:
- Approved labor categories
- Proposed personnel
- Key personnel requirements
- Hourly or salary rates
- Level of effort
- Technical roles
- Founder involvement
- Subcontractor labor
- Direct versus indirect labor
- Overtime treatment
- Timekeeping codes
- Billing rate support
The company should not wait until invoicing to determine whether labor was recorded correctly.
Build Indirect Rate Support
Indirect rates often become more important in federal contracting.
The company may need to support fringe, overhead, G&A, or other indirect rates through actual accounting records.
SBIR.gov explains that indirect rates should be developed from the company’s own accounting system, annual budget, projected cost categories, or company-specific cost information.
Before contract performance begins, review:
- Indirect cost pools
- Allocation bases
- Fringe treatment
- Overhead treatment
- G&A treatment
- Direct labor base
- Total cost input base
- Unallowable cost exclusions
- Provisional billing rates
- Actual rate forecast
- Rate ceiling or contract limitations
- Impact on invoices or vouchers
If indirect rates are not supported, the company may underbill, overbill, or struggle during review.
Understand Provisional Billing Rates
For cost-reimbursable work, the company may need provisional billing rates.
SBIR.gov notes that after passing the pre-award accounting survey and receiving an SBIR/STTR Phase II award, companies need to start thinking about submitting a Provisional Billing Rate Proposal to DCAA.
A provisional billing rate is used to bill indirect costs during performance before final actual rates are known.
To prepare, organize:
- Forecasted indirect cost pools
- Forecasted allocation bases
- Payroll projections
- Overhead assumptions
- G&A assumptions
- Direct labor forecast
- Subcontractor and material assumptions
- Unallowable cost exclusions
- Budget-to-actual review process
- Rate adjustment process
Provisional rates should be monitored during performance, not forgotten after submission.
Prepare Invoicing and Voucher Support
Contract invoicing requires discipline.
Depending on the contract type, invoices may be based on:
- Allowable costs incurred
- Labor hours
- Contract line items
- Milestones
- Deliverables
- Progress payments
- Fixed scheduled amounts
- Materials or subcontractor costs
Before invoicing begins, define:
- Who prepares invoices
- Who reviews invoices
- What records support each invoice
- Which system is used
- How often invoices are submitted
- How indirect costs are included
- How subcontractor costs are included
- How unallowable costs are excluded
- How prior payments are reconciled
- Where invoice support is stored
Each invoice should have a complete support file.
Watch Funding Ceilings and Limitation of Funds
Federal contracts may include funding ceilings or incremental funding limits.
The company should track:
- Total contract value
- Funded amount
- Unfunded amount
- Contract line-item funding
- Costs incurred
- Invoices submitted
- Payments received
- Remaining funded balance
- Burn rate
- Notification requirements
- Modification status
Cost-reimbursable contracts may not allow unlimited reimbursement simply because work continues.
The company should understand funding limits before costs exceed available funding.
Review Cash Flow Before Signing
Federal contract growth can strain cash flow.
Even when the contract is profitable on paper, the company may need to pay payroll, vendors, consultants, and subcontractors before receiving payment.
Review:
- Payroll timing
- Invoice timing
- Payment terms
- Indirect cost recovery
- Subcontractor payment terms
- Materials and equipment timing
- Billing frequency
- Retainage or holdbacks, if any
- Milestone acceptance risk
- Working capital needs
- Delays in contract modifications or approvals
Cash flow planning should happen before performance begins.
Prepare for DCAA Expectations
Not every federal contract will involve DCAA in the same way.
But companies pursuing DoD cost-reimbursable work or Phase II follow-on opportunities should be prepared.
SBIR.gov explains that DCAA involvement in Phase II may include pre-award surveys, pricing scrutiny, post-award accounting system audits, and incurred cost audits during performance.
DCAA-related questions may focus on:
- Accounting system adequacy
- Timekeeping
- Labor distribution
- Indirect rates
- Incurred cost submissions
- Billing support
- Direct and indirect cost classification
- Unallowable costs
- Policies and procedures
- General ledger control
Preparing early is easier than reconstructing records later.
Understand Incurred Cost Responsibilities
Cost-reimbursable contracts may require incurred cost submissions or related support.
SBIR.gov explains that DCAA may review the entire accounting system to confirm it is operating as represented during the pre-award phase.
To prepare, maintain:
- General ledger detail
- Trial balance
- Indirect rate schedules
- Payroll records
- Timekeeping
- Labor distribution
- Vendor invoices
- Subcontractor records
- Billing history
- Unallowable cost detail
- Cost transfer support
- Reconciliations
Incurred cost readiness is built during performance, not after the contract ends.
Separate Contract Work From Commercial Work
After SBIR/STTR funding, companies often pursue customers, pilots, investors, and commercial growth alongside federal contracts.
The accounting system should separate:
- Federal contract work
- SBIR/STTR award work
- Customer-funded work
- Internal R&D
- Commercial product development
- Sales and marketing
- Fundraising
- General operations
- Unallowable costs
The company should not use a federal contract to subsidize commercial work or use commercial activity to mask federal contract cost problems.
Manage Subcontractor Costs Carefully
Federal contracts may include subcontractors, consultants, vendors, or research partners.
Before work begins, review:
- Approved subcontractor budget
- Scope of work
- Flow-down clauses
- Invoice requirements
- Deliverables
- Payment terms
- Period of performance
- Indirect cost treatment
- Travel or material support
- Monitoring responsibilities
- Closeout requirements
Subcontractor invoices should be reviewed before payment and before inclusion in federal invoices or vouchers.
Review Unallowable Costs
Unallowable costs must be identified and excluded when required.
Examples requiring review may include:
- Fundraising
- Investor activity
- Certain lobbying
- Entertainment
- General sales activity
- Non-contract commercialization costs
- Unsupported costs
- Costs outside the period of performance
- Personal or non-business costs
Set up accounts or codes to make these costs visible.
Do not wait for invoice preparation to identify unallowable activity.
Build Policies and Procedures
Federal contract growth requires written procedures.
The company should document:
- Timekeeping procedures
- Labor distribution process
- Direct cost policy
- Indirect cost policy
- Unallowable cost policy
- Purchasing procedures
- Expense approvals
- Subcontractor invoice review
- Billing procedures
- Indirect rate calculation process
- Cost transfer policy
- Record retention
- Monthly close process
Procedures help the team apply the accounting system consistently.
Create a Federal Contract Readiness Checklist
Before accepting or performing the first federal contract after SBIR/STTR funding, review:
- Contract type
- Payment terms
- Contract clauses
- Cost-reimbursable requirements
- Fixed-price risk
- Accounting system adequacy
- Project codes and cost objectives
- Timekeeping
- Labor distribution
- Indirect rate support
- Provisional billing rates
- Invoice or voucher support
- Funding ceilings
- Cash flow forecast
- DCAA readiness
- Incurred cost requirements
- Subcontractor management
- Unallowable cost treatment
- Written procedures
- Record retention
This checklist helps the company move from award accounting to contract-ready operations.
Common Mistakes After SBIR/STTR Funding
Companies often run into trouble when they assume federal contracting is just the next version of grant management.
Common mistakes include:
- Accepting contract terms without reviewing accounting impact
- Treating cost-reimbursable work like a fixed grant budget
- Underestimating fixed-price performance risk
- Not setting up contract project codes
- Starting work before timekeeping is ready
- Not connecting payroll to labor distribution
- Using unsupported indirect rates
- Submitting invoices without support files
- Ignoring funding ceilings
- Not preparing for DCAA questions
- Mixing contract work with commercial work
- Not planning cash flow before performance
- Waiting until closeout to organize records
These issues are easier to prevent before the first contract begins.
Questions to Ask Before Your First Federal Contract
Before bidding, signing, or performing a federal contract after SBIR/STTR funding, ask:
- What contract type is being offered?
- How will payment work?
- What costs must be tracked?
- Is the contract cost-reimbursable, fixed-price, or hybrid?
- What records will support invoices or vouchers?
- Are indirect rates involved?
- Is the accounting system adequate?
- Is timekeeping ready?
- Can payroll be tied to labor distribution?
- Are unallowable costs separated?
- Are subcontractor costs properly supported?
- What DCAA involvement may occur?
- What cash flow risks exist?
- What happens if costs exceed the price or funded amount?
- What closeout records will be required?
These questions help the company understand whether it is ready for federal contract growth.
Final Thoughts: Federal Contract Growth Requires Stronger Accounting
SBIR/STTR funding can be the starting point for larger federal opportunities.
But the first federal contract after SBIR/STTR funding can introduce new financial requirements, especially around cost-reimbursable contracts, fixed-price risk, DCAA expectations, invoicing, indirect rates, timekeeping, accounting system adequacy, and cash flow.
At Peter Witts CPA PC, we help SBIR/STTR companies prepare for federal contract growth so accounting systems, billing support, indirect rates, labor records, and cash flow planning are ready before contract performance begins.
