A biotech startup wins a $150,000 DoD SBIR Phase I award. The founder tracks expenses in a spreadsheet, bills the contract as firm-fixed-price, delivers the feasibility report, and collects payment. No audit. No rate negotiation. No DCAA involvement.
Twelve months later, the same firm wins a $1.2 million Phase II. The contracting officer requests an SF 1408 pre-award accounting system survey. DCAA schedules the review. The agency asks for provisional indirect rates, a compliant timekeeping system, and segregated cost pools.
The founder has none of it.
The Phase II award sits in limbo while the firm scrambles to build an accounting infrastructure from scratch. Six weeks of setup work delays the project start, burns through cash reserves, and signals to the agency a contractor unprepared for cost-type work.
This is the standard SBIR story. SBIR accounting requirements shift dramatically between Phase I and Phase II, and the gap surprises over 2,000 first-time awardees every year.
Phase I is a research deliverable with minimal financial oversight. Phase II is a federal cost-type contract with the same accounting standards as a $50 million defense prime. The system requirements, audit exposure, and compliance obligations are different in every measurable way.
SBIR Accounting Requirements: Phase I vs Phase II
The difference in SBIR accounting requirements between Phase I and Phase II is not incremental. The gap is structural. Phase I operates under firm-fixed-price rules where the government pays an agreed amount for a deliverable. Phase II operates under cost-reimbursement rules where the government pays actual documented costs plus a fixed fee.
Cost-reimbursement changes everything about how your books must work. Every dollar billed must be traceable to a specific cost category, allocated to the correct project, classified as allowable under FAR Part 31, and supported by source documentation.
| Factor | Phase I | Phase II |
|---|---|---|
| Award size | Up to $314,363 | Up to $2,095,748 |
| Duration | 6-12 months | 2-3 years |
| Contract type | Firm-fixed-price (FFP) | Cost-plus-fixed-fee (CPFF) |
| Accounting system | Basic bookkeeping | DCAA-compliant (SF 1408) |
| Timekeeping | Basic time tracking | Daily, employee-signed, DCAA-compliant |
| Indirect rates | Minimal scrutiny | Documented, auditable, provisional rates required |
| Audit risk | Minimal | Pre-award survey + post-award incurred cost audit |
| Record retention | Standard business practice | 3 years after final payment [FAR 4.703] |
| Cost segregation | Not required for FFP | Direct, indirect, and unallowable must be separated |
| Professional support | Local bookkeeper sufficient | GovCon-experienced CPA recommended |
The award size caps reflect SBA’s October 2024 thresholds. Agencies sometimes exceed these caps with SBA approval for specific programs.
Phase I SBIR Accounting: What Your Books Actually Need
Phase I awards are firm-fixed-price. The government pays an agreed amount for a research report or feasibility study. Your accounting obligation is straightforward: track the money, deliver the work, report the results.
Minimum requirements for Phase I:
- Separate bank account. Never commingle SBIR funds with personal or other business accounts. Open a dedicated business checking account for the award. This is not a regulatory mandate for FFP, but it prevents the single most common first-timer mistake.
- Basic job costing. Track expenses against the Phase I award as a distinct project in your accounting software. Even though FFP does not require cost reporting, you need this data for your Phase II proposal budget.
- Time tracking. Record hours worked on the project. Phase I does not require DCAA-compliant timekeeping, but NSF and several agencies recommend it. More importantly, your Phase II proposal will require labor hour estimates. Actual Phase I hours are the best basis for those estimates.
- Expense documentation. Keep receipts, invoices, and travel records organized by project. Phase I audit risk is minimal, but Phase II proposal reviewers will ask how you developed your cost estimates.
What you do NOT need for Phase I: Provisional indirect rates, an SF 1408-compliant system, CAS compliance, incurred cost submissions, or DCAA-formatted timesheets. Save the overhead of building these systems until Phase II is awarded or imminent.
The Phase I trap: Do not wait until Phase II is awarded to start system setup. If your Phase I work is progressing toward a Phase II proposal, begin building the accounting infrastructure during Phase I, months 8 through 12. The pre-award survey happens before the Phase II contract is signed. Firms building their system after the award delays the project start and erodes agency confidence.
Phase II: The Full Compliance Build
Phase II transforms your SBIR accounting requirements entirely. A cost-reimbursement contract means the government pays your actual costs. For DoD and NASA contracts, DCAA has authority to audit every dollar. For NIH and NSF grants, the agency Inspector General or Single Audit process provides oversight. Your accounting system must pass the SF 1408 pre-award survey before the Phase II contract is signed.
The 5 systems you need for Phase II:
1. DCAA-Compliant Accounting System
Your system must meet all criteria on the SF 1408 checklist. The core requirements: segregate direct costs by contract, accumulate indirect costs in logical pools, exclude unallowable costs from billing, and produce reports tying costs to specific awards.
QuickBooks Desktop or Online handles this for firms under $10 million in revenue. The DCAA-compliant QuickBooks setup requires a structured chart of accounts with separate classes or jobs for each SBIR award, indirect cost pools (fringe, overhead, G&A), and an unallowable cost center.
2. DCAA-Compliant Timekeeping
DCAA timekeeping for Phase II requires daily time recording by each employee, with hours allocated to specific projects or indirect categories. Timesheets must be signed by the employee and approved by a supervisor. Corrections must show the original entry, the corrected entry, and the reason for the change.
Salaried employees working more than 40 hours per week create an uncompensated overtime situation affecting labor rates. Total compensation divided by total hours (including uncompensated hours) produces the effective hourly rate for billing. Missing this calculation is one of the top SBIR audit findings [FAR 37.115; FAR 31.205-6].
3. Indirect Rate Structure
Phase II requires documented indirect rates for fringe benefits, overhead, and G&A expenses. The contracting officer negotiates provisional billing rates before the contract starts.
DCAA audits actual rates against provisional rates at contract completion through the incurred cost submission process.
For a small SBIR firm, a two-pool structure (overhead + G&A, with fringe loaded into overhead) is common and defensible. As the firm grows and adds contracts, a three-pool structure (fringe, overhead, G&A) becomes necessary.
Agency-specific rate limitations:
- NIH: Caps indirect (F&A) rates at 40% of total direct costs for Phase I. Phase II rates above 40% are permissible if negotiated with DFAS.
- NSF: Caps the combination of indirect costs plus fringe benefits at 150% of direct labor. This forces SBIR firms to manage total loaded labor costs carefully.
- DoD: No agency-specific cap. Rates must be reasonable and allocable under FAR Part 31.
4. Cost Segregation by Award
Every cost charged to the Phase II award must be classified as direct or indirect. Direct costs (labor, materials, travel, subcontracts) must be identifiable to the specific SBIR project. Indirect costs must flow through properly structured pools with documented allocation bases.
If you hold multiple SBIR awards simultaneously (common for firms with Phase I and Phase II running in parallel), each award needs its own job code or class in the accounting system. Cross-charging between awards is a finding waiting to happen.
5. Written Policies and Procedures
DCAA expects written accounting policies covering timekeeping, travel reimbursement, purchasing, compensation, and cost allocation. These do not need to be elaborate. A 2-3 page document for each policy area is sufficient for a small SBIR firm. The policies must match your actual practices. DCAA tests for consistency between written policy and observed behavior.
Contracts vs. Grants: Different Rules, Same Money
SBIR awards come in two forms depending on the issuing agency, and the SBIR accounting requirements differ significantly between them.
| Factor | Contracts (DoD, NASA) | Grants (NIH, NSF, DOE) |
|---|---|---|
| Governing standard | FAR Part 31 | 2 CFR Part 200 (Uniform Guidance) + FAR Part 31 for NSF |
| Audit authority | DCAA | Agency Inspector General or Single Audit (2 CFR 200.501) |
| Pre-award survey | SF 1408 (DCAA) | NSF: Capability Assessment Process (CAP). NIH: Financial management review |
| Payment method | Voucher-based billing | Drawdown requests (NSF uses ACM$ system) |
| Deliverable expectation | Specified deliverables at checkpoints | Progress reports, less prescriptive on deliverables |
| Indirect rate treatment | Negotiated provisional rates | Agency-specific caps (NIH 40%, NSF 150% of labor) |
| IR&D allowability | Generally allowable | NSF and NIH: unallowable |
The NSF exception: NSF issues grants but requires awardees to follow FAR Part 31 cost principles, not the standard 2 CFR 200 cost principles most grant recipients use. This means NSF SBIR recipients face grant administration rules with contract-level cost scrutiny. Build your system to FAR Part 31 standards regardless of whether your award is a contract or grant.
The Phase II Setup Timeline
Start building your Phase II accounting system during the last quarter of your Phase I performance period. Waiting until after the Phase II award delays the contract start and burns cash.
| When | Action |
|---|---|
| Phase I Month 8 | Engage a GovCon-experienced CPA or bookkeeping firm. Begin chart of accounts restructuring for DCAA compliance. |
| Phase I Month 9 | Implement DCAA-compliant timekeeping. Start recording daily hours by project and indirect category. |
| Phase I Month 10 | Establish indirect rate pools (fringe, overhead, G&A). Calculate provisional rates from 3-6 months of actual data. |
| Phase I Month 11 | Draft written accounting policies (timekeeping, travel, compensation, cost allocation, purchasing). |
| Phase I Month 12 | Run a mock SF 1408 self-assessment. Fix gaps before submitting the Phase II proposal. |
| Phase II Pre-Award | Complete the SF 1408 pre-award survey with DCAA or agency reviewer. Negotiate provisional billing rates. |
| Phase II Month 1 | Begin billing actual costs against provisional rates. Start the incurred cost tracking process. |
Firms starting this process at Phase I month 8 arrive at Phase II pre-award with 4-5 months of compliant financial data. Firms starting after Phase II is awarded arrive with zero months of data and a contracting officer wondering if the system works.
6 SBIR Accounting Mistakes First-Time Awardees Make
These SBIR accounting mistakes appear in nearly every advisory firm’s case files. Each one is preventable with the right setup during Phase I.
- Commingling SBIR and personal funds. Using a personal checking account for SBIR expenses makes cost segregation impossible to demonstrate. Open a dedicated business account before depositing the first dollar of award funds.
- Proposing unrealistic indirect rates. Underestimating indirect costs on the Phase II proposal creates a cash flow crisis when actuals exceed projections. Overestimating risks an overbilling finding. Base your proposed rates on actual data from Phase I, not guesses.
- No timekeeping system until Phase II starts. DCAA evaluates whether your timekeeping system produces reliable data. A system with 30 days of history is not credible. Start daily time tracking during Phase I to build a track record.
- Treating the Phase II budget as an allowance. Phase II is cost-reimbursable. You bill actual costs, not budget line items. Spending $50,000 on equipment when your budget shows $30,000 is allowable if the cost is reasonable and necessary. Billing $50,000 for travel when actuals were $30,000 is fraud. Track actuals against budget categories and report variances.
- Ignoring uncompensated overtime. A salaried engineer working 50 hours per week on SBIR has an effective hourly rate lower than their nominal rate. Billing at the nominal rate overbills the government. Calculate effective rates using total hours worked, not standard 40-hour weeks [FAR 37.115].
- No written policies. DCAA checks for written timekeeping, travel, and compensation policies during the pre-award survey. “We do it this way” is not a policy. A 2-page written procedure for each area satisfies the requirement. Draft them during Phase I setup.
Program Status: SBIR Reauthorized Through 2031
SBIR/STTR program authority expired on September 30, 2025, creating a six-month gap in new solicitations. Congress passed the Small Business Innovation and Economic Security Act in March 2026, reauthorizing both programs through September 30, 2031.
The reauthorization means agencies are issuing new solicitations again. Existing awards continued throughout the gap period under their original terms. The new law incorporates provisions from Senator Ernst’s INNOVATE Act and updates program parameters.
For current awardees: Your Phase I or Phase II funding is unaffected. The gap period created no disruption to existing awards. Agencies administered all obligations on schedule throughout.
For prospective applicants: Agencies are releasing solicitations from the backlog created during the authorization gap. Firms with compliant SBIR accounting systems will respond faster than firms starting from scratch. Build the accounting infrastructure now, before submitting your first proposal.
Frequently Asked Questions
Do I need a DCAA-compliant accounting system for SBIR Phase I?
No. Phase I awards are firm-fixed-price, requiring only basic bookkeeping. However, setting up job costing and time tracking during Phase I prepares you for Phase II and produces the cost data needed for your Phase II proposal budget. NSF specifically recommends DCAA-compliant systems even for Phase I.
What triggers an SF 1408 pre-award survey for SBIR?
A Phase II cost-reimbursement award from DoD, NASA, or other contracting agencies triggers the survey. DCAA evaluates your accounting system against 14 criteria (SF 1408, Section II) covering cost segregation, timekeeping, indirect rates, and unallowable cost treatment. NIH and NSF use their own assessment processes instead of SF 1408, but evaluate comparable criteria.
How are SBIR grants different from SBIR contracts for accounting?
Contracts (DoD, NASA) follow FAR Part 31 cost principles with DCAA audit authority. Grants (NIH, NSF, DOE) follow 2 CFR Part 200 (Uniform Guidance), with NSF additionally requiring FAR Part 31 cost principles. The practical difference: contracts face DCAA pre-award surveys and incurred cost audits. Grants face agency-specific financial reviews with different indirect rate caps.
What indirect rate caps apply to SBIR awards?
NIH caps indirect (F&A) rates at 40% of total direct costs. NSF caps the combination of indirect costs plus fringe at 150% of direct labor. DoD and NASA impose no agency-specific caps, but rates must be reasonable under FAR Part 31. Proposed rates significantly above industry norms trigger additional scrutiny during rate negotiations.
When should I start building my Phase II accounting system?
During Phase I, month 8 of 12. This gives you 4-5 months to implement DCAA-compliant timekeeping, establish indirect rate pools, draft written policies, and run a mock SF 1408 self-assessment before the Phase II pre-award survey. Starting after Phase II is awarded delays the project start and signals unpreparedness to the contracting officer.
Is the SBIR program still active in 2026?
Yes. Program authority expired September 30, 2025, but Congress passed the Small Business Innovation and Economic Security Act in March 2026, reauthorizing SBIR/STTR through September 30, 2031. Existing awards continued uninterrupted during the gap. Agencies are now issuing new solicitations from the backlog created during the six-month authorization lapse.
Key Takeaways
- SBIR Phase I (firm-fixed-price, up to $314,363) requires basic bookkeeping. Phase II (cost-reimbursable, up to $2,095,748) requires a DCAA-compliant accounting system passing the SF 1408 pre-award survey. The gap between phases is structural, not incremental.
- Start building your Phase II SBIR accounting infrastructure during Phase I month 8. Implement timekeeping, establish indirect rate pools, and draft written policies before the Phase II proposal goes in.
- DoD and NASA SBIR awards are contracts governed by FAR Part 31 with DCAA audit authority. NIH and NSF awards are grants governed by 2 CFR Part 200, with NSF additionally requiring FAR Part 31 cost principles. Build to FAR Part 31 standards regardless of award type.
- The top first-timer mistakes: commingling funds, unrealistic indirect rates, no timekeeping history, and missing written policies. All four are preventable with 8-12 weeks of Phase I setup work.
- SBIR/STTR was reauthorized in March 2026 through September 30, 2031. Agencies are releasing a backlog of solicitations. Build compliance infrastructure now before submitting proposals into the new solicitation cycle.
