SBIR/STTR and Commercial Revenue: How to Keep Federal and Customer-Funded Work Separate

Oct 22 2026 01:30

Lyka Dagulo

For many SBIR/STTR companies, commercial revenue represents an important milestone.

 

A technology developed with federal research funding begins attracting customers. A potential buyer agrees to a pilot project. A company signs its first commercial contract or starts generating revenue from a product that began as federally funded research.

 

These are encouraging developments.

 

But they also introduce financial responsibilities that can make an already complex accounting environment more challenging.

 

The company may now be managing federally funded research, customer-funded development, commercial product improvements, sales activities, and internal R&D at the same time.

 

Employees may work across several activities. Software and laboratory equipment may support both federal and commercial projects. Founders may move between research, customer meetings, fundraising, and general management throughout the same week.

 

Without a clear accounting structure, costs can become mixed.

 

The goal is not to separate federal research from commercialization as business strategies. It is to ensure that each activity receives the appropriate accounting treatment and that federal awards are charged only for costs they should bear.

 

At Peter Witts CPA PC, we help SBIR/STTR awardees and federally funded businesses establish accounting systems that support both federal compliance and commercial growth.

 

Why Federal and Commercial Cost Separation Matters

 

SBIR/STTR companies are often built around technologies with commercial potential.

 

Federal research funding helps businesses investigate technical feasibility, develop innova tive solutions, and advance technology toward broader applications.

 

As companies begin serving customers, however, the accounting system must support more than one type of activity.

 

It should be able to answer:

  • Which expenses belong to the federal award?

  • Which costs support customer-funded work?

  • Which activities are internal R&D?

  • Which expenses relate to commercialization?

  • Which costs support general operations?

  • How should shared employee time be allocated?

  • How should shared facilities and software be treated?

  • Are federal awards absorbing costs that belong elsewhere?

  • How does commercial activity affect indirect rates?

  • Can the company report federal and commercial financial performance separately?

These questions are important for both compliance and financial decision-making.

 

When costs are not properly separated, federal award reports may become unreliable.

 

At the same time, leadership may struggle to understand whether commercial products and customer contracts are profitable.

 

A strong accounting system should support both objectives.

 

Federal Funding and Commercial Revenue Are Different Financial Activities

 

Federal research awards and commercial customer contracts may support related technology, but they serve different purposes.

 

Federally Funded R&D

 

Federal R&D activity involves work performed under an approved grant, cooperative agreement, or government contract.

 

Costs should be accumulated and reported according to the applicable award requirements.

 

Depending on the award, this may include:

  • Research personnel

  • Technical development

  • Prototype activities

  • Testing and validation

  • Materials and supplies

  • Approved consultants

  • Research subawards

  • Project-specific travel

  • Applicable indirect costs

Customer-Funded Work

 

Customer-funded activity may involve performing work for a commercial client.

 

Examples include:

  • Paid pilot projects

  • Customer-specific development

  • Testing services

  • Product customization

  • Implementation work

  • Commercial engineering

  • Technical support

  • Consulting services

These costs should be identifiable separately from federal award costs.

 

Internal R&D

 

Internal research and development may support company-funded innovation outside an active federal award.

 

This can include research on future product capabilities, technical improvements, or work being developed for a future proposal.

 

General Business Activities

 

General operations may include executive management, accounting, human resources, business administration, fundraising, and sales activity.

 

The appropriate accounting treatment depends on the nature of each cost and applicable cost principles.

 

The same technology can generate several distinct financial activities. The accounting system needs to distinguish which activity benefited from each cost.

 

Step 1: Establish Separate Project Codes

 

One of the most effective ways to separate federal and commercial costs is through project-level accounting.

 

Depending on the software, project tracking may use:

  • Projects

  • Jobs

  • Classes

  • Cost centers

  • Contracts

  • Grants

  • Departments

  • Customer codes

Each significant activity should be separately identifiable.

 

For example:

 

Project Code Activity
NIH-P2-001 NIH SBIR Phase II research
DOD-RD-002 DoD-funded development
COMM-001 Customer-funded pilot
COMM-002 Commercial product implementation
IRD-001 Internal R&D
ADMIN-001 General business operations

 

llustrative coding structure only.

 

When expenses are recorded, the general ledger account identifies the expense type, while the project code identifies the activity that benefited.

 

For example, the company may use a general ledger account for direct engineering labor across several projects.

 

The project code distinguishes whether that labor supported an NIH award or a commercial customer engagement.

 

This approach reduces the need to create separate general ledger accounts for every award and customer combination.

 

Step 2: Maintain a Chart of Accounts That Supports Both Activities

 

A standard tax-focused chart of accounts may not provide enough detail for companies managing federal awards and commercial work.

 

The chart should support categories such as:

  • Direct federal labor

  • Direct commercial labor

  • Indirect labor

  • Fringe benefits

  • Technical materials

  • Testing services

  • Consultants

  • Subawards and subcontracts

  • Commercial delivery costs

  • Shared facilities

  • Administrative expenses

  • Internal R&D

  • Sales and marketing

  • Fundraising

  • Unallowable costs

Project codes and cost objectives should provide further detail.

 

The objective is not to create unnecessary complexity.

 

It is to make sure the company can prepare accurate reports for each type of activity without repeatedly reconstructing transactions.

 

Step 3: Separate Employee Time Across Federal and Commercial Projects

 

Labor is often one of the largest costs for SBIR/STTR companies.

 

Employees may move between federal research and commercial activities within the same pay period.

 

For example, a software engineer may spend time on:

  • Federally funded algorithm development

  • A customer-funded pilot

  • Internal product improvements

  • General technical support

The company should maintain timekeeping records that identify the work performed and applicable cost objectives.

 

Example: Allocating Employee Time

 

Assume an engineer earns $6,000 in gross wages during a monthly payroll period.

 

The employee's supported work records show the following allocation:

 

Activity Share of Compensated Activity Allocated Wages
NIH SBIR Research 50% $3,000
Commercial Customer Pilot 30% $1,800
Internal R&D 15% $900
General Administrative Work 5% $300
Total 100% $6,000

Illustrative example assuming a supported proportional allocation method. Actual allocations must comply with the company's compensation policies and applicable award requirements.

 

The entire $6,000 should not automatically be charged to the federal award.

 

The accounting system should assign labor to the activities that benefited from the work.

 

This helps establish accurate federal research costs and commercial project expenses.

 

Step 4: Connect Timekeeping to Payroll and Labor Distribution

 

Timekeeping identifies where employees worked.

 

Payroll records show how much employees were paid.

 

Labor distribution connects these records by assigning compensation to the appropriate projects and accounting classifications.

 

A reliable process should reconcile:

  • Employee time records

  • Payroll registers

  • Salary or wage rates

  • Direct federal labor

  • Direct commercial labor

  • Indirect labor

  • Internal R&D

  • General administrative activity

  • General ledger postings

For applicable government contracts, DCAA accounting system guidance emphasizes the ability to identify labor by cost objective and reconcile labor distribution to payroll and cost records.

 

For federal assistance awards, personnel expense documentation must support the applicable allocation of salary and wages.

 

This is especially important when the same employees support multiple grants, government contracts, or commercial customers.

 

Step 5: Separate Customer-Funded Pilots From Federal Research

 

Customer-funded pilots can be particularly difficult to distinguish from SBIR/STTR activities.

 

A pilot may involve testing technology originally developed under a federal award.

 

However, the source of the technology does not determine which project should bear the cost of the pilot.

 

The company should review:

  • Customer agreement

  • Statement of work

  • Pilot deliverables

  • Technical activities

  • Employee time

  • Materials and software

  • Customer payment terms

  • Federal award scope

  • Applicable intellectual property or use restrictions

Example: Federal Research and a Commercial Pilot

 

An SBIR-funded company develops an advanced sensor.

 

The federal award supports research into the sensor's technical capabilities.

 

A commercial customer later pays the company to integrate that sensor into a specific industrial system.

 

Although both projects involve the sensor, the customer integration work may be a separate commercial cost objective.

 

The company should not automatically charge customer-specific engineering, installation, or delivery costs to the federal research award.

 

Instead, those costs should be assigned based on actual project benefit and the applicable agreements.

 

This distinction helps protect federal cost accounting while providing more accurate customer profitability information.

 

Step 6: Track Commercial Product Development Separately

 

Commercial product development may continue while federal research is active.

 

Examples include:

  • Product interface improvements

  • Customer-requested features

  • Production engineering

  • User experience changes

  • Commercial packaging

  • Deployment tools

  • Product support systems

  • Customer onboarding capabilities

Some activities may overlap technically with federally funded R&D.

 

The appropriate accounting treatment should be determined by the approved federal scope, actual work performed, and applicable requirements.

 

If the commercial development work does not benefit the federal award, it should not be charged directly to that award.

 

Why This Matters for Commercialization Strategy

 

Separating commercial development costs helps leadership understand how much the company is investing beyond federal research.

 

That information can support:

  • Product pricing

  • Commercialization budgets

  • Customer profitability analysis

  • Hiring plans

  • Investment decisions

  • Future funding projections

For a growing SBIR/STTR company, these are important CFO-level considerations.

 

Step 7: Account for Internal R&D Properly

 

Internal R&D should be distinguishable from federally funded research and commercial customer work.

 

Examples may include:

  • Developing future technology capabilities

  • Research outside an approved award scope

  • Exploring new technical approaches

  • Building platform features for future products

  • Company-funded prototype development

  • Work supporting future opportunities

However, internal R&D has specific accounting implications.

 

For government contractors, independent research and development costs may be subject to particular FAR provisions, including FAR 31.205-18.

 

They should not automatically be treated as ordinary direct expenses or assumed to be unallowable.

 

The proper accounting treatment depends on the applicable rules and company cost structure.

 

A strong accounting system should identify internal R&D activity so it can be classified and allocated appropriately.

 

Step 8: Separate Sales, Marketing, and Fundraising

 

Commercial growth requires investment in activities beyond research and product development.

 

These may include:

  • Sales meetings

  • Customer acquisition

  • Advertising

  • Product demonstrations

  • Investor presentations

  • Capital raising

  • Business development

  • Marketing campaigns

  • Financing negotiations

These costs should be identified separately from direct federal research expenses.

 

Some may be allowable indirect expenses under particular circumstances.

 

Others may be unallowable for federal cost recovery.

 

For example, certain capital-raising activities are generally unallowable under applicable FAR cost principles.

 

The company should not assume all sales, marketing, or commercialization spending receives the same treatment.

 

Founder Time Creates Additional Risk

 

A founder may spend the morning reviewing SBIR research results and the afternoon meeting investors.

 

If all founder time is charged to the federal award, the accounting system may overstate direct labor costs.

 

Timekeeping and labor distribution should distinguish those activities.

 

This is particularly important for startups where founders perform both technical and executive responsibilities.

 

Step 9: Review Shared Software, Facilities, and Equipment

 

Not every expense can be assigned exclusively to one project.

 

Shared resources may include:

  • Cloud computing

  • Laboratory facilities

  • Engineering software

  • Testing equipment

  • Office space

  • Utilities

  • IT infrastructure

  • Shared technical personnel

  • Insurance

A company may use these resources for both federal and commercial work.

 

The accounting treatment depends on whether the cost can be directly identified with a project or should be allocated through an indirect cost method.

 

Example: Shared Cloud Computing

 

Suppose the company spends $5,000 per month on cloud infrastructure.

 

The infrastructure supports federally funded research, a commercial customer application, and internal development.

 

The company should evaluate whether usage can be measured reliably.

 

If project-specific usage is identifiable and direct charging is appropriate, the costs may be assigned accordingly.

 

If the expense is properly treated as indirect, it should be accumulated and allocated through the applicable cost pool and base.

 

The company should not charge the full expense directly to the federal award merely because the research project uses the infrastructure.

 

Consistency is essential.

 

Step 10: Understand How Commercial Work Affects Indirect Rates

 

This is one of the most important financial considerations when an SBIR/STTR company begins generating commercial revenue.

 

Indirect costs support more than one activity.

 

A company may have overhead and G&A expenses that benefit both federal and commercial projects.

 

As commercial operations expand, the company's cost allocation structure may need review.

 

For applicable government contracts, FAR 31.203 addresses the accumulation and allocation of indirect costs.

 

It emphasizes logical cost groupings and allocation bases that reflect the benefits received by cost objectives.

 

Commercial work should not be omitted from an applicable allocation base simply because it is not federally funded.

 

Example: Federal and Commercial Labor Base

 

Suppose a company uses an appropriate direct labor dollar base for its overhead rate.

 

Its annual figures are:

 

Category Amount
Federal direct labor $400,000
Commercial direct labor $200,000
Total applicable direct labor base $600,000
Overhead cost pool $300,000

 

The illustrative overhead rate is:

 

$300,000 ÷ $600,000 = 50%

 

If the company incorrectly excluded commercial direct labor from the applicable base, the calculated rate would rise to 75%.

 

That could improperly shift shared overhead costs toward federal work.

 

Illustrative example only. The appropriate pool, base, exclusions, and rate methodology depend on the company's cost accounting practices and applicable requirements.

 

This demonstrates why commercial growth can change indirect cost calculations.

 

The correct goal is not to maximize indirect rates.

 

It is to allocate costs consistently and according to the benefits received.

 

Step 11: Separate Commercial Revenue From Federal Funding

 

The accounting system should also identify different revenue streams.

 

Depending on the company's activities, these may include:

  • Federal grant funding

  • Government contract revenue

  • Commercial product sales

  • Customer-funded engineering services

  • Pilot project revenue

  • Licensing revenue

  • Subscription revenue

  • Other commercial services

Different award instruments and commercial arrangements may require different revenue recognition and financial reporting treatment.

 

For example, federal grant funding should not automatically be treated as equivalent to revenue from a product sale.

 

The accounting treatment should reflect the substance of the funding arrangement and the applicable financial reporting framework.

 

Why Revenue Separation Matters

 

Separate revenue reporting helps leadership understand:

  • Federal funding dependence

  • Commercial revenue growth

  • Customer concentration

  • Product profitability

  • Cash flow sources

  • Funding runway

  • Revenue diversification

  • Future operating needs

These insights can help the company move from grant-dependent operations toward a more sustainable commercial business.

 

Step 12: Build Separate Budget-to-Actual Reports

 

Federal award budgets and commercial operating budgets serve different purposes.

 

Federal budget-to-actual reporting helps determine whether expenditures remain within the authorized award structure.

 

Commercial project reporting helps leadership understand profitability and financial performance.

 

For example:

 

Financial Activity Primary Reporting Focus
NIH SBIR Phase II Approved budget, actual expenditures, remaining funds
Commercial Pilot Customer revenue, delivery costs, project margin
Internal R&D Development spending, resource allocation, investment
General Operations Administrative costs, overhead, cash requirements

 

These reports should connect to the same underlying accounting records while presenting information appropriate to each activity.

 

A company should not need to rebuild financial data manually every time management asks whether a commercial project is profitable.

 

Step 13: Monitor Profitability by Commercial Project

 

Commercial revenue is not the same as commercial profitability.

 

A company may sign a $150,000 pilot agreement but incur substantial costs to deliver it.

 

Those costs may include:

  • Engineering labor

  • Customer-specific testing

  • Materials

  • Cloud infrastructure

  • Travel

  • External consultants

  • Applicable indirect costs

Without project-level accounting, leadership may overestimate the financial contribution of commercial work.

 

Example: Commercial Pilot Profitability

 

Consider a hypothetical customer-funded pilot:

 

Category Amount
Customer revenue $150,000
Direct engineering labor ($55,000)
Materials and testing ($25,000)
External technical services ($15,000)
Contribution before allocated overhead $55,000

 

Illustrative example only. It does not represent final operating profit or account for all possible indirect expenses.

 

The company should also evaluate applicable overhead and operating expenses before concluding that the pilot is profitable.

 

For SBIR/STTR founders, commercial project accounting provides valuable information when negotiating future customer agreements.

 

Step 14: Reconcile Shared Costs Monthly

 

A monthly review should confirm that federal and commercial costs are properly separated.

 

The review may include:

  • Employee timekeeping

  • Payroll allocation

  • Project codes

  • Shared software expenses

  • Facility costs

  • Equipment usage

  • Consultant invoices

  • Customer-funded project expenses

  • Internal R&D

  • Sales and fundraising costs

  • Indirect cost pools and bases

  • General ledger reconciliation

  • Federal budget-to-actual reports

  • Commercial project reports

This is also the time to identify missing project codes, inconsistent classifications, or costs that may need correction.

 

Cost transfers should be documented and based on the project or activity that actually benefited—not used to shift spending toward an award with available funds.

 

Step 15: Establish Written Cost Allocation Procedures

 

As a company grows, consistent accounting becomes more difficult when decisions depend entirely on founder judgment.

 

Written procedures should explain:

  • How federal projects are identified

  • How commercial projects are established

  • How employee time is recorded

  • How payroll is distributed

  • How direct costs are assigned

  • How shared expenses are allocated

  • How internal R&D is classified

  • How indirect costs are accumulated

  • How unallowable costs are identified

  • How commercial revenue is recorded

  • How cost corrections are reviewed

  • How monthly reconciliations are completed

Policies should reflect the company's actual operations and applicable requirements.

 

The objective is to establish repeatable accounting processes that remain reliable as the number of awards, customers, and employees increases.

 

Common Mistakes When Federal and Commercial Work Overlap

 

Several common accounting problems arise when SBIR/STTR companies begin commercial operations.

 

Charging Commercial Development to an SBIR/STTR Award

 

Using technology developed under federal funding does not automatically make later customer-specific development an award cost.

 

Tracking All Engineering Work Under One R&D Code

 

This makes it difficult to distinguish federal research, internal development, and customer-funded activity.

 

Failing to Separate Founder Activities

 

Founder time spent on fundraising, general management, or commercial sales should not automatically be treated as direct federal labor.

 

Excluding Commercial Work From Indirect Cost Calculations

 

If commercial projects benefit from shared indirect costs, excluding them from an applicable allocation base can distort rates.

 

Charging Shared Software Entirely to One Award

 

Shared resources need appropriate direct assignment or indirect allocation.

 

Treating All Commercialization Spending the Same Way

 

Different activities may receive different treatment depending on scope, cost principles, and award terms.

 

Using Commercial Revenue to Infer Profitability

 

Without project-level cost tracking, commercial contracts may appear more profitable than they are.

 

Making Unsupported Cost Transfers

 

Moving expenses between federal and commercial projects without documentation can create financial reporting and compliance risk.

 

Relying on Separate Spreadsheets Instead of Reconciled Accounting Records

 

Spreadsheets may be useful, but the underlying information should reconcile to the company's accounting system.

 

Federal and Commercial Cost Separation Checklist

 

Use this checklist to assess whether your accounting system supports both federally funded research and commercial operations.

  • Each federal award has a separate project code.

  • Customer-funded projects are separately identifiable.

  • Commercial product development is tracked.

  • Internal R&D is distinguishable from funded research.

  • Sales, marketing, and fundraising activity can be identified.

  • Direct and indirect costs are classified consistently.

  • Unallowable costs are separately identifiable.

  • Employee timekeeping covers applicable work activities.

  • Payroll and labor distribution reconcile to project costs.

  • Founder compensation is supported by activity records.

  • Shared software and facilities are allocated appropriately.

  • Equipment and technical resources have suitable tracking.

  • Indirect cost pools reflect the company's current operations.

  • Allocation bases include applicable commercial activities.

  • Commercial project profitability can be evaluated.

  • Cost transfers are documented and approved.

  • Monthly reconciliations are completed.

  • Written cost allocation policies are maintained.

If several items remain incomplete, the company may need to review its accounting structure before commercial activity becomes more complex.

 

Frequently Asked Questions About SBIR/STTR and Commercial Revenue

 

Can an SBIR/STTR Company Earn Commercial Revenue While Performing a Federal Award?

 

Yes. SBIR/STTR companies can pursue commercial activities while performing federal research awards, subject to applicable program, award, and other legal requirements.

 

The important accounting consideration is properly identifying the costs and revenues associated with each activity.

 

Can the Same Employees Work on Federal and Commercial Projects?

 

Yes.

 

However, their compensation should be allocated using appropriate supporting records and consistent accounting methods.

 

Timekeeping and labor distribution are important when employees work across multiple cost objectives.

 

Can Software Developed Under an SBIR Award Be Used Commercially?

 

Commercial use may be possible, but the answer depends on the award's intellectual property, data rights, licensing, commercialization, and other applicable terms.

 

The accounting treatment of additional commercial development is a separate question from the right to commercialize the technology.

 

Are Commercialization Costs Allowable Under SBIR/STTR Awards?

 

Some commercialization-related activities may be expressly authorized under particular award terms or funding mechanisms.

 

Other activities may not be chargeable.

 

Companies should review the approved scope and agency requirements instead of treating all commercialization spending as allowable federal costs.

 

Should Commercial Work Be Included in Indirect Rate Calculations?

 

Commercial activities that benefit from shared indirect expenses generally need to receive an appropriate allocation under the applicable cost accounting method.

 

The exact treatment depends on the cost pools, allocation bases, and governing requirements.

 

Is Internal R&D the Same as Federal R&D?

 

No.

 

Internal R&D is distinguishable from work performed under an approved federal award.

 

Its accounting and cost recovery treatment depends on the company's cost structure and applicable rules.

 

Does Commercial Revenue Affect SBIR/STTR Eligibility?

 

Generating commercial revenue does not automatically make a company ineligible for SBIR/STTR funding.

 

However, eligibility depends on applicable SBA program requirements, including ownership, control, size, affiliation, and other relevant conditions.

 

Companies should review current eligibility requirements when applying for new funding.

 

Final Thoughts: Federal Compliance and Commercial Growth Need the Same Financial Foundation

 

Commercialization is an important objective for many SBIR/STTR companies.

 

But the transition from federally funded research to customer-funded work creates accounting challenges that should be addressed early.

 

A company needs to distinguish federal projects, commercial customers, internal development, and general business activities while maintaining consistent cost allocation, labor distribution, indirect rate calculations, and financial reporting.

 

The result is more than stronger compliance.

 

It is better visibility into where resources are being spent, which projects generate financial returns, and how the business can support its next stage of growth.
