Who Uses Due Diligence

Due diligence serves both sides of the transaction

Whether you’re evaluating an acquisition or preparing a business for sale, the right diligence helps surface issues early, reduce surprises, and strengthen your position.

For Buyers

Buy-Side Due Diligence

Understand what you’re buying before you commit. Validate earnings, uncover legal and operational risks, and identify issues that could affect price, financing, or deal terms.

Verify earnings quality and cash flow before you commit
Identify legal, regulatory, and operational risks early
Build negotiating leverage with third-party findings
Satisfy lender requirements for SBA or conventional financing
or
For Sellers

Sell-Side Due Diligence

Find and address issues before buyers do. Prepare cleaner financials, uncover potential diligence concerns, reduce surprises, and strengthen your negotiating position before going to market.

Surface and fix issues before they become deal-killers
Present clean, verified financials to prospective buyers
Reduce re-trading risk by controlling the diligence narrative
Accelerate time-to-close with fewer surprises
How It Looks in Practice

Example: Financial due diligence for a first-time SBA acquisition

A real scenario showing how DueDilio connects buyers with vetted independent DD firms — from project submission to engagement.

The Scenario

Quality of Earnings for a regional home services company

Deal Size
$4.2M (SBA-backed)
Service
Quality of Earnings (QofE)
Industry
Home Services (HVAC)
Timeline
LOI signed, 45-day close window

A first-time buyer under LOI needed a QofE report to satisfy both their own diligence and SBA lender requirements. They had 45 days to close and needed a firm that could start immediately and deliver within 3 weeks.

What Clients Say

From buyers who used DueDilio for due diligence

4.9 on Trustpilot

“DueDilio listened to the type of work I needed to complete as well as the parameters I needed to work within. Within a few days I had ~15 applications and set up calls with my top 3 choices. The individual I ended up hiring did phenomenally.

Tom
Quality of Earnings

“They were very responsive and paired me up with a consultant quickly. He definitely knew his stuff — provided valuable perspective on the quality of the financials and was a very clear communicator. He came in under budget and ultimately gave me the extra level of comfort I was looking for.

Jesse S.
Financial Due Diligence

“Working with DueDilio has been a fantastic experience. Traditionally, finding the right firm takes a lot of trial and error — DueDilio took a several-weeks process and distilled it down to a few days. The providers were all very qualified. The hardest part was selecting only one.

Common Questions

What clients ask about due diligence

Answers to the questions we hear most — from first-time buyers under LOI to experienced acquirers evaluating scope.

Every provider in DueDilio’s network goes through a multi-step vetting process before they can receive projects — evaluating M&A transaction experience, professional credentials, deal-size fit, and client references. The majority of applicants are declined. Providers compete for your project on the strength of their qualifications, not their firm name, and those who consistently underperform are removed from the network.

Yes — compressed timelines are one of the most common situations buyers bring to DueDilio. After you submit a project, proposals typically start arriving within the first hour. Providers in DueDilio’s network are accustomed to M&A deadlines and will confirm their availability and earliest start date as part of their proposal. If your timeline is critical, note it in your submission so providers can respond accordingly.

No. The project intake form is designed to work even if you’re not sure what you need. Describe your deal — the business type, deal size, and where you are in the process — and providers will recommend appropriate scope in their proposals. Most buyers refine their DD plan based on the proposals they receive, not before. If you want guidance before submitting, the Founder Advisory Session is designed for exactly that.

Cost varies by scope, deal size, complexity, and provider. A focused QofE on a lower middle market business typically ranges from $5,000 to $20,000+, depending on the number of years under review and turnaround time. Legal and other DD disciplines are often scoped separately. Submitting a project is the fastest way to get accurate pricing — proposals include detailed scope and fees, and you can compare them side by side before committing to anything.

Once you submit, DueDilio matches your project to vetted providers whose experience fits your deal profile. Those providers review your project and submit structured proposals — including scope, timeline, and pricing. You receive proposals directly in your dashboard, can review anonymous provider profiles, message providers directly, and schedule calls. There’s no obligation to hire from any proposal you receive. If no proposals are the right fit, you’re under no pressure to move forward.
