Will Customers Stay After the Deal Closes?
Customer Due Diligence
Buy With Confidence. Or Walk Away Smarter.
Customer Due Diligence is a structured, confidential interview process that helps business buyers evaluate customer loyalty, retention risk, competitive position, owner dependency, pricing and value perception, and future growth opportunity before an acquisition.
We do not just capture customer feedback. We identify meaningful patterns, interpret what they mean for the business, and provide practical insights that help buyers evaluate risk, strengthen deal confidence, support valuation discussions, and prepare for post-close priorities.

The Questions That Matter Most Before Closing
-
Will Customers Stay After the Deal Closes?
Revenue only matters if customers continue to buy after the transition. Understanding customer loyalty and retention risk helps buyers assess future revenue stability.
-
What Happens When the Seller Steps Away?
Many businesses rely on long-standing personal relationships. We help determine whether customers are loyal to the company or primarily to the owner, and what that could mean after the transition.
-
Why Do Customers Choose This Company?
Customers often reveal competitive advantages and strengths that are not visible in financial statements or management presentations.
-
Are Competitors Creating Customer Retention Risk?
Customers provide valuable insight into competitor activity, pricing pressure, service expectations, and market dynamics.
-
Where Are the Growth Opportunities?
Customers often identify unmet needs, expansion opportunities, cross-selling potential, and ways to strengthen future growth.
The Cost of Missing Customer Risk
A Customer Risk Issue Can Change the Entire Deal
Customer findings may reinforce the investment thesis, reveal a need for stronger transition planning, support valuation or negotiation discussions, identify post-close priorities, or give the buyer a reason to pause. The goal is not to create alarm. It is to replace assumptions with informed judgment.
How We Help You Find the Answers
Built for Confidentiality. Designed for Buyers.
This is not a mass customer survey, a hidden audit, or an uncontrolled outreach process. It is a limited, discreet, structured interview process designed to surface patterns and context.
Watch: How Customer Due Diligence Works
1
We Create a Customized Approach to Your Goals
We review the transaction, customer selection, revenue concentration, and buyer priorities, so the interviews are tailored to your goals and the questions you need answered. What we typically explore:
Why customers stay or leave
How the business compares to competitors
Whether customers believe they're getting good value
Where future growth could come from
2
We Manage Outreach Professionally and Carefully
No customer is contacted without approval. Outreach is handled discreetly and professionally to protect the relationship and keep the process moving.
How we protect the seller relationship: Sellers approve the outreach plan, customers are not told the business is for sale, and interviews are positioned as a limited customer feedback conversation. The goal is to gather useful insight without creating unnecessary concern or disruption.
3
We Interview for Patterns, Not Soundbites
We separate one-off comments from recurring patterns and connect the findings to deal risk, revenue stability, valuation discussions, and post-close planning.
4
We Give Practical Interpretation, Not Just Feedback
We assess satisfaction, retention risk, switching signals, competitive alternatives, owner dependency, pricing/value perception, and growth opportunities.
Most customer due diligence engagements run 3 to 5 weeks, depending on interview volume and scheduling. When timing is compressed, we call out where findings are directional and where additional coverage would increase confidence.
How Customer Due Diligence Helps Buyers Make Better Decisions
Validate recurring revenue and customer loyalty
Strengthen valuation and negotiation discussions
Confirm or challenge management assumptions
Prioritize post-close initiatives
Reduce the risk of unexpected customer loss
What Buyers Receive
Every engagement is customized, but buyers typically receive:
Executive summary of key findings
Customer interview themes and supporting insights
Retention and switching risk indicators
Customer relationship and owner dependency analysis
Competitive positioning insights
Pricing and value perception feedback
Growth opportunity observations
Practical recommendations for diligence and post-close planning
The result is greater clarity, stronger decision-making, and confidence to move forward with the acquisition, renegotiate the deal, or walk away altogether.

What Buyers Learned Before They Closed
“This is amazing and extremely detailed. I can’t believe you got the customers to elaborate on so many key areas. This is incredibly helpful for our goals moving forward.”
— Investor“When you're looking at making an acquisition and then managing post-close, Mayfield is critical. They help us understand market reputation, customer feedback, and opportunities to improve. It's a multifaceted value.”
— Investor“I engaged Mayfield Consulting to understand how critical a vertical software solution was to its clients. The insights they uncovered went far deeper than what I got from the seller or my own interviews. They were an invaluable partner.”
— Searcher“We were told the company had sticky recurring revenue. Mayfield uncovered that 60% came from just two customers with verbal agreements. Huge catch.”
— Search Fund PrincipalFAQs
-
We go beyond Net Promoter Score. Our interviews reveal how sticky your customers really are, what makes them stay, and what would make them leave. Many of our clients say the interviews alone were worth the cost of the entire review.
-
No. Customer outreach is carefully managed and no customer contact occurs without approval.
-
The number depends on customer concentration, deal size, and diligence objectives.
-
Yes. Buyers engage us before, during, and after due diligence depending on their objectives.
-
Yes. We’ve helped clients avoid multi-million-dollar mistakes — and also confirmed when a deal’s upside was real.
-
Timing depends on scope, transaction stage, and the questions being answered.
-
Many clients continue working with Mayfield after closing to help prioritize opportunities, address risks, and build a plan for growth.
Using the insights gathered during diligence, we help leadership teams strengthen customer relationships, improve operations, refine messaging, enhance revenue systems, and focus on the initiatives that can create the greatest impact and long-term value.
-
We typically support private equity firms, search funds, family offices, independent sponsors, and strategic buyers who are evaluating a business and want a clearer view of customer risk, market position, operational readiness, and post-close growth potential.
-
Customer outreach is handled carefully. Sellers approve the outreach plan, customers are not told the business is for sale, and interviews are positioned as a limited customer feedback conversation. The goal is to gather useful insight without creating unnecessary concern or disruption.
-
Surveys and standard customer calls often produce surface-level feedback. Our interviews are scheduled in advance at the customer's convenience, giving them dedicated time to provide thoughtful input. The conversation allows us to explore important topics in greater depth, and uncover insights that are often missed through surveys or routine customer conversations.
-
We can begin by reviewing available customer, sales, and market information to identify potential risks and opportunities. If helpful, we can also provide the seller with an overview of the interview process, how confidentiality is protected, and how the findings may benefit them if the buyer chooses to share the results after closing. If customer interviews become appropriate later, they can be added as part of a phased approach.
We Help Buyers Make Better Decisions
Sometimes the findings increase confidence to move forward. Sometimes they strengthen negotiations. Sometimes they identify priorities for Day One ownership. And sometimes they help buyers avoid a costly acquisition altogether.
Our goal isn't to convince you to buy. It's to help you make the right decision.
