Buying a small business is complicated. You need attorneys, due diligence specialists, financial analysts, and deal advisors, often all at once, but finding and vetting them yourself takes weeks you probably don't have.
DueDilio is a curated online marketplace that solves exactly that problem.
The platform connects buyers, sellers, independent sponsors, and private equity firms with pre-vetted M&A professionals for transactions in the $1M to $25M range.
It's free for clients to use, delivers proposals within 36 hours, and handles the sourcing and vetting work so you don't have to.
Key Takeaways
- DueDilio is free for buyers to use, with revenue coming from service providers in its network.
- The platform specializes in lower middle market deals between $1M and $25M in enterprise value.
- Clients receive multiple curated proposals within 36 hours of submitting a project.
What Is DueDilio?
DueDilio is a marketplace and advisory service, not an M&A firm. The company does not provide due diligence or legal services itself.
Instead, it acts as a matching layer between people buying or selling small businesses and the professionals they need to get deals done.
Think of it like a staffing agency for M&A deal teams, but with a structured vetting process and a focus on speed.
The platform targets a specific corner of the market: the lower middle market. Deals under $1M are generally too small, and deals over $25M are typically served by bulge bracket banks and large consulting firms.
DueDilio fills the gap for the buyer who just signed an LOI on a $4M HVAC company and now needs a quality of earnings report and an M&A attorney in the next two weeks.
Who Uses DueDilio?
The client base is fairly specific. DueDilio works with:
- Search fund operators pursuing their first acquisition
- Independent sponsors putting together deals without committed capital
- Boutique private equity firms and family offices running lean deal teams
- Entrepreneurs buying a business through the SBA or conventional financing
This is not a platform for Fortune 500 companies or billion-dollar transactions.
The sweet spot is the individual buyer or small investment group that needs professional M&A support but doesn't have a full-time in-house team.
How the Platform Works
The process is three steps and straightforward.
Step 1: Submit your project.
You describe what you need, the type of transaction, the deal size, timeline, and budget.
DueDilio account managers work with you to finalize the project scope. The entire intake process takes a few minutes and is confidential.
Step 2: Review proposals.
Within 36 hours (often sooner), DueDilio delivers multiple curated proposals from service providers in their network.
Each proposal is matched to your project scope and budget. You can request free phone consultations with providers before committing to anyone.
Step 3: Hire a provider.
You choose the provider that fits and move forward. DueDilio stays available throughout the engagement.
There's no obligation to hire after receiving proposals, and no cost to the client at any stage.
The Service Provider Network
This is where DueDilio's value proposition lives or dies. The network currently includes 200+ vetted service providers.
According to DueDilio's own network stats:
| Metric | Figure |
|---|---|
| Vetted Service Providers | 200+ |
| With Big 3 or Big 4 Experience | 60% |
| With Advanced Degrees | 75% |
| Average Years of Experience | 12–20 years |
Providers go through a multi-step vetting process that includes an initial application screening, a phone interview, an online background check, and a review of past work.
DueDilio also monitors ongoing client feedback and can remove providers who don't maintain service standards.
The network pulls from several professional backgrounds:
- Big Four accounting firms (financial due diligence, forensic accounting)
- Boutique law firms (M&A attorneys, contract drafting)
- Management consultancies (strategy, value creation)
- Investment banks (deal structuring, financial modeling)
- Independent consultants and acquisition entrepreneurs
That breadth matters because most small business deals don't need a single type of help.
A buyer might need a QoE analyst, a transaction attorney, and a fractional CFO for post-acquisition integration, sometimes all in the same 60-day window.
Services Available on DueDilio
DueDilio organizes its service categories into four main stages of a transaction:
Pre-LOI Services
- M&A coaching
- Deal sourcing support
- Business valuation
- Deal modeling
- SBA financing guidance
Legal Services
- LOI and Asset Purchase Agreement drafting
- Legal due diligence
- Document review and negotiation support
- PPM drafting
Post-LOI Due Diligence
- Quality of Earnings (QoE) reports (both lite and full scope)
- Financial due diligence
- Technology due diligence
- Commercial due diligence
- Background checks on sellers and key personnel
Post-Acquisition Services
- Accounting and bookkeeping setup
- Fractional CFO, CTO, and CMO services
- Marketing and technology support
- Business integration
The ability to cover all four phases under one platform is genuinely useful.
A buyer who found their CPA through DueDilio can come back for legal support post-LOI, and then again for a fractional CFO six months after closing.
Pricing: What Does DueDilio Actually Cost?
DueDilio is free for clients. You pay nothing to submit a project, receive proposals, or consult with providers.
The company earns revenue from the service providers in its network through commissions on facilitated transactions.
The professionals in the network set their own rates, and because you receive multiple competing proposals, there's built-in price comparison.
Several client reviews mention saving significantly compared to hiring providers directly. One reviewer noted the platform saved them $5,000 to $10,000 on their deal.
Another described getting professional financial analysis at "a fraction of the price" of going the traditional route.
Pricing from service providers will vary based on scope, deal complexity, and the provider's background. A lite QoE report for a $3M deal will cost considerably less than a full-scope QoE on a $20M transaction.
DueDilio's account managers can help you set realistic budget expectations before proposals go out.
Knowledge Center
Beyond the marketplace function, DueDilio maintains a free Knowledge Center with articles, checklists, templates, and case studies aimed at small business buyers.
Recent topics include post-LOI due diligence timelines, how to compare quality of earnings providers, and why the majority of small business listings never close.
The resources are practical and written for someone actively in a deal, not an academic audience.
DueDilio also offers a free 30-page M&A guide updated for 2026 and a free 30-minute consultation with their team via Calendly for buyers who aren't sure where to start.
What Clients Say
DueDilio maintains a Trustpilot profile with consistently positive reviews. The recurring themes across client feedback are speed, cost savings, and the quality of providers matched to their projects.
A few representative data points from verified reviews:
- A search fund operator described receiving multiple well-matched proposals despite providing minimal project detail upfront.
- A family office client noted that service was both faster and less expensive than sourcing providers independently.
- An investor said the platform connected them with a financial analyst whose work helped reduce the business asking price by nearly 20%.
- A boutique PE firm used DueDilio for a financial and tax due diligence project and rated the team as responsive with short turnaround times.
The negative feedback that exists is minor and mostly related to regional limitations or cases where the client ultimately chose a local provider over the matched candidates, which says more about deal-specific logistics than platform quality.

Is DueDilio Right for You?
If you're pursuing a small business acquisition in the $1M to $25M range and you don't have an established network of M&A professionals, DueDilio is worth using. The fact that it's free to try makes the risk essentially zero.
The platform is most valuable for first-time buyers, search fund operators, and lean deal teams that would otherwise spend days cold-calling advisors, comparing rates manually, and hoping for the best.
Experienced acquirers with existing professional relationships may find less incremental value, but even repeat buyers use it to fill capability gaps quickly.
Conclusion
DueDilio addresses a real and underserved problem in the lower middle market: assembling a competent M&A deal team quickly and affordably.
For buyers working in the $1M to $25M transaction range, it's a practical first stop before, during, and after a deal.
