Grant consulting for SBIR proposals ranges from $5,000 to $25,000 per application on a flat-fee basis, or 5-15% of the award on a success-fee basis. The spread is wide. The market includes freelance writers charging $5K for a template-driven proposal, all the way to specialized firms charging $20K+ for agency-specific strategy, research, and writing.
Here's how to evaluate what you're paying for and whether it's worth it.
What are the real cost ranges for grant consultants?
| Model | Cost Range | When You Pay | Total Cost on $305K NSF Win |
|---|---|---|---|
| Flat fee | $5,000-$25,000 per proposal | Upfront (sometimes milestone-based) | $5,000-$25,000 |
| Hourly | $150-$400/hour | Monthly invoices | $8,000-$30,000 (50-80 hours typical) |
| Retainer | $2,000-$8,000/month | Monthly | $6,000-$24,000 (3-6 month engagement) |
| Success fee | 5-15% of award | Only if you win | $15,250-$45,750 |
| Hybrid | Small upfront + reduced success fee | Split | Varies |
The cheapest option on paper (success fee at 0% upfront) is often the most expensive in total dollars if you win. A 10% success fee on a $305K NSF Phase I is $30,500. A flat fee for the same proposal might be $10,000-$15,000.
What's included at each price tier?
Not all $10K proposals are equal. Here's what separates a $5K engagement from a $20K one:
$5,000-$8,000 (budget tier):
- Writing assistance based on your technical input
- Basic formatting and compliance checking
- Template-driven approach (reusable across clients)
- Limited agency research
- You provide all technical content and strategy
$10,000-$15,000 (mid-tier):
- Strategy and agency matching guidance
- Technical writing and narrative framing
- Agency-specific review criteria optimization
- 1-2 rounds of revision based on internal review
- Budget development assistance
- Basic competitive landscape research
$18,000-$25,000 (full-service):
- Comprehensive competitive assessment and agency matching
- Full technical writing with original research integration
- Mock review simulation (scoring against agency criteria)
- Multiple revision cycles
- Budget development and justification
- Commercialization plan development
- Post-submission support and resubmission strategy
When does a grant consultant pay for itself?
The decision to hire a consultant is a probability calculation, not a cost calculation:
Expected Value = (Win Probability x Award Amount) - Consulting Cost
| Scenario | Win Probability | Award | Expected Value | Cost | Net Expected Value |
|---|---|---|---|---|---|
| DIY (no consultant) | 15% | $305,000 | $45,750 | $0 | $45,750 |
| Budget consultant | 20% | $305,000 | $61,000 | $7,000 | $54,000 |
| Mid-tier consultant | 25% | $305,000 | $76,250 | $12,000 | $64,250 |
| Full-service consultant | 30% | $305,000 | $91,500 | $20,000 | $71,500 |
A mid-tier consultant who increases your win probability from 15% to 25% generates ~$18,500 in expected value improvement for a $12,000 investment. That's a positive ROI even on a single application.
The math gets dramatically better with a multi-proposal strategy. If you're applying to 3 agencies, the consultant's research and positioning work transfers across proposals. That reduces the per-proposal cost while maintaining the probability improvement.
Can you charge consulting fees to the SBIR grant itself?
This comes up in every discussion about grant consultant pricing, and the answer is nuanced.
FAR 31.205-33(f) prohibits charging the government for costs related to "activities to influence the award of a contract." Some interpret this as prohibiting success-fee arrangements where the consultant's compensation is contingent on winning.
The practical reality:
- If you pay a consultant a flat fee from your own funds (not from the grant), this provision doesn't apply. You're paying for professional services from company revenue.
- If you include a consultant's flat fee as a line item in your SBIR budget (under "other direct costs" or "contractual"), this is generally allowable -- it's paying for proposal preparation services, not contingent on the award.
- If you pay a consultant a success fee from the SBIR award proceeds after winning, this is where the FAR provision creates risk. The fee is contingent on the award, which arguably falls under the prohibition.
- Many firms structure success fees to be paid from company funds (not directly from the grant account), which creates legal distance from the FAR provision.
Our recommendation: Understand the distinction between allowable consulting costs (budgeted in the proposal) and contingent fees (paid from award proceeds). If you're considering a success-fee arrangement, ask the firm how they structure payment to address FAR compliance. If they've never heard of FAR 31.205-33(f), that's a red flag.
What are the red flags when evaluating grant consultants?
"We guarantee you'll win." No one can guarantee a grant award. SBIR success rates run 15-25% even for strong proposals. Any firm making guarantees is either lying or doesn't understand the process.
No agency specialization. "We write grants for all agencies" usually means they write the same generic proposal with different headers. NSF, NIH, DoD, and DARPA have fundamentally different review criteria and evaluation cultures. Your consultant should know the specific agency you're targeting.
Won't share their win rate or references. A credible firm should be able to tell you their win rate (or at least a range), the agencies they've worked with, and put you in touch with past clients. Vague claims of "high success rates" with no specifics are meaningless.
No upfront assessment of your competitiveness. A good consultant tells you whether your technology is competitive for a specific program before taking your money. If they'll take any client for any agency without assessing fit, they're optimizing for their revenue, not yours. At Cada, we tell roughly 30% of companies that come to us that grants aren't the right path for them -- that honesty is how trust gets built.
They recommend programs that compete with their own services. Some state programs (like FAST/TBED) provide free SBIR writing assistance. If your consultant never mentions these options, ask why.
Should you DIY your grant proposal or hire a consultant?
| Factor | DIY | Consultant |
|---|---|---|
| Cost | $0 (your time) | $5,000-$25,000 |
| Time investment | 80-120 hours for first proposal | 20-40 hours (your time for technical input) |
| Agency knowledge | You learn from scratch | They already know the reviewer culture |
| Win probability | ~15% (first-time average) | ~25-35% (with experienced consultant) |
| Reusability | You build the skill internally | You depend on the consultant for future proposals |
| Best for | Founders with technical writing ability and time | Founders who are time-constrained or writing their first proposal |
The honest answer: If you're a strong technical writer, have 80+ hours available, and are applying to one agency, DIY is viable. If you're time-constrained, applying to multiple agencies, or writing your first government proposal, a consultant significantly improves your odds and cuts your time cost.
The worst option is hiring a cheap, generic consultant. You pay money and get a mediocre proposal that doesn't meaningfully improve your odds. If you're going to invest, invest in someone with agency-specific expertise and a track record you can verify.
What to expect from a strategy review vs. full proposal writing
These are different services with different price points:
Strategy review / grant roadmap ($0-$5,000):
- Assessment of your technology's grant competitiveness
- Identification of best-fit agencies and programs
- Competitive positioning analysis
- Recommended application sequence
- Some firms (including Cada) offer this for free as the first step in a client relationship
Full proposal writing ($5,000-$25,000 per application):
- Complete technical narrative writing
- Budget development and justification
- Agency-specific formatting and compliance
- Internal review and revision cycles
- Submission support
The smart approach: Start with a strategy review before committing to full proposal writing. A $2,000 roadmap that tells you to apply to NSF instead of NIH could save $20,000 in misguided consulting fees. It could also save months of wasted effort on a program where you're not competitive.
