One of the hardest lessons I learned while scaling Totality Services was that a business that relies on the founder to solve every technical crisis isn't a business—it's a high-paying job. During MSP due diligence, investigators look for the "hero culture."
They want to see that your Service Level Agreements (SLAs) are met because of your processes, not because your lead engineer worked until 2 AM to fix a preventable issue.
If it isn't documented, it doesn't exist. This is a mantra every MSP owner should live by. During an audit, you’ll be asked to show your Standard Operating Procedures (SOPs). This includes everything from client onboarding to offboarding, password management, and emergency response.
Proper documentation ensures that if a key engineer walks out the door tomorrow, the business continues to function. This lowers the risk for a buyer and increases the trust a client has in your longevity.
A Professional Services Automation (PSA) tool is the heartbeat of an MSP. Sophisticated due diligence doesn't just check if you have a PSA; it checks if you're actually using it. They look at:
Average time to respond vs. time to resolve.
Ticket backlog trends.
Accuracy of time tracking (which affects your understanding of client profitability).
Consistency in RMM (Remote Monitoring and Management) alerting.
If your PSA is a mess, it suggests your service delivery is reactive rather than proactive.
This is where the rubber meets the road. In the modern landscape, an MSP is a prime target for supply chain attacks. Consequently, MSP due diligence now leans heavily into the security posture of the MSP itself, not just what they provide to clients.
Luis Navarro, the founder of MSP Agenda, often emphasises that security is not just a technical checkbox; it’s a commercial necessity. If you can’t prove your own environment is secure, why should a client trust you with theirs?
Expect a deep dive into your internal tools. Are you using Multi-Factor Authentication (MFA) on every single portal? Is your RMM locked down with IP filtering? How do you manage administrative privileges? If the MSP’s internal security is lax, the entire client base is at risk. This is often a deal-breaker in M&A scenarios.
A "snowflake" MSP—where every client has a different firewall, a different backup solution, and a different antivirus—is an operational nightmare. Due diligence teams look for standardisation. A standardised stack means:
Lower training costs for engineers.
Faster troubleshooting.
Better margins through vendor volume discounts.
Easier scalability.
The more unique each client environment is, the more "technical debt" a buyer is inheriting.
You can claim you have backups, but due diligence will demand proof of successful restores. They will look for the frequency of backup testing and the physical/logical separation of backup data. In the era of ransomware, an MSP that cannot prove the integrity of its clients' data is a liability.
Contracts are the foundation of your enterprise value. During MSP due diligence, legal teams will review every Master Service Agreement (MSA) and Statement of Work (SOW). They aren't just looking for signatures; they are looking for specific clauses that protect the business and ensure revenue continuity.
- Auto-Renewal Clauses: These provide revenue predictability and are highly valued by buyers.
- Limitation of Liability: Does your contract protect you if a client suffers a breach? Or is the MSP on the hook for unlimited damages?
- Assignability: If you sell the business, do you need the client's permission to transfer the contract? If so, the deal becomes much harder to close.
- Termination for Convenience: Contracts that allow a client to leave with 30 days' notice for no reason are significantly less valuable than those with fixed terms.
When Luis Navarro co-founded Totality Services, he spent years sitting between technical teams and business leaders. He learned that the commercial strength of a contract is just as important as the technical service it describes. A strong MSA is a sign of a commercially mature MSP.
An MSP is a people business. During MSP due diligence, the focus shifts to the staff. Who are the key players? What is the turnover rate? If the top three engineers are the only ones who know how to manage the core infrastructure, the business has a "knowledge silo" problem.
Buyers will look at payroll data to ensure engineers are being paid market rates. If you’ve artificially inflated your profit by underpaying your team, a buyer knows they’ll have to increase expenses post-acquisition to keep the talent. They will also look at non-compete agreements and employment contracts to ensure the intellectual property and client relationships are protected.
Whether you are preparing for a sale or just want to run a better business, conducting "self-due diligence" is a powerful exercise. It allows you to identify and fix issues before they are exposed by an outside party.
- Financials: Three years of tax returns, P&Ls, and a clean balance sheet.
- Client Data: A list of all clients, their MRR, contract end dates, and service history.
- Technology Stack: A full inventory of internal and client-facing tools.
- Security: Documentation of internal security policies and recent audit results.
- Operations: Access to the PSA for ticket metrics and SOP libraries.
If you're finding that your security reviews are inconsistent or hard to track, tools like MSP Agenda can help standardise the process. By creating clear, commercially-minded security reports, you not only protect the client but also build the documentation trail that due diligence teams love to see.
Even successful MSPs often stumble during the audit phase. One common mistake is "revenue masking," where hardware sales or one-time projects are lumped into recurring revenue figures. This is easily spotted and immediately erodes trust.
Another pitfall is the "messy" cap table or unclear ownership of IP. If a former partner still owns a piece of the company or if your custom automation scripts aren't clearly owned by the business, it can stall a deal for months.
Due diligence is a full-time job on top of your existing full-time job. Many MSP owners become distracted, leading to a dip in service quality or sales during the process. This dip can then be used by a buyer to renegotiate the price. Staying focused on the day-to-day while managing the audit is crucial.
In MSP due diligence, not all revenue is treated equally. Strategic value comes from having a niche (e.g., specialising in legal or healthcare) or having a proprietary way of delivering service that others can't easily replicate.
A buyer might pay a premium for an MSP that has a perfect SOC2 compliance record because it allows them to enter a new market. Conversely, a high-profit MSP with poor technical standards might be seen only as a "fixer-upper" and valued accordingly.
As Luis Navarro experienced with the eight-figure acquisition of Totality Services, the goal is to make yourself redundant. If the due diligence team sees that the business can grow without the founder’s constant involvement in sales or technical escalations, the valuation goes up. The best MSPs are those where the founder focuses on strategy, not ticket resolution.
It’s not just about M&A. Large enterprise clients or those in regulated industries (like finance or defence) will perform their own MSP due diligence before signing a contract. They will ask for your Cyber Essentials plus, your SOC2 reports, and your business continuity plans.
If you aren't prepared for these questions, you won't win the bigger, more profitable contracts. Security reviews should be a standard part of your relationship, not just something you scramble to provide when asked.
When you present a security recommendation, the client needs to see the commercial impact. Using a structured approach to these reviews ensures that you are tracking decisions and creating accountability. This level of professionalism is exactly what due diligence teams look for when vetting a service provider.
The landscape of MSP due diligence is changing. Five years ago, the focus was almost entirely on the P&L. Today, "Cyber Due Diligence" is just as important. Insurance companies are now part of the conversation, as they won't insure an acquisition if the target MSP has significant security gaps.
Expect deep scans of your external footprint and potentially even "gray box" testing of your internal systems. A single unpatched vulnerability in your RMM could be the difference between a successful exit and a failed deal.
The best way to pass a cyber audit is through radical standardisation. When every client is on the same version of the same software, managed by the same scripts, the attack surface is predictable and manageable. Fragmentation is the enemy of security and the enemy of a high valuation.
