How to Sell a Security Company in Michigan

Michigan's security services market is consolidating fast. The state's industrial base in southeast Michigan, coupled with growing commercial real estate activity in Grand Rapids and the Detroit metro region, has made security companies attractive acquisition targets for PE firms and search funds looking to build platforms in the Midwest. If you've spent the last 15-25 years building recurring revenue through alarm monitoring, mobile patrol, or integrated security systems, now is a genuine window to exit at valuations that reflect what you've built.

Who Is Buying Security Services Businesses in Michigan

Search funds are the most active buyer type in Michigan right now. These are typically experienced operators backed by investment capital who acquire single companies and run them independently. They value recurring revenue, established customer relationships, and clean operations, and they're hunting for businesses in the $1-4 million EBITDA range. Regional PE firms based in Chicago and Columbus are also acquiring Michigan security companies as add-ons to existing platforms or as standalone investments. Larger national security consolidators like Convergint, Prosegur, and Garda continue to scan Michigan markets for tuck-in acquisitions. Independent sponsors (high-net-worth individuals backed by debt financing) are becoming more active in the Midwest and often move faster than traditional PE groups, though they typically focus on larger targets above $2 million in EBITDA. All of these buyers are looking for businesses with 70% or higher gross margins, strong customer retention (85%+ annually), and management depth beyond the owner.

What Your Business Needs to Look Like Before You Go to Market

• Three years of audited or reviewed tax returns plus normalized P&L statements showing adjusted EBITDA. Remove one-time costs, owner perks, and non-recurring expenses. Buyers will verify these numbers, and discrepancies kill deals.
• A detailed customer list with contract terms, renewal dates, monthly recurring revenue per account, and customer acquisition cost. Buyer confidence in your revenue quality depends entirely on this data.
• Documentation of your key personnel and a realistic transition plan. If the business depends on you personally, you'll lose 20-30% of valuation. Identify which roles stay post-close and build out job descriptions.
• Clean customer contracts showing terms, pricing, and escalation clauses. Buyers will request these; missing or unclear agreements create post-close disputes and price reductions.
• Evidence of operational systems separate from you: dispatch software, compliance documentation, training protocols, and service delivery standards. This proves the business can run without you.
• A rundown of your top 10-15 customers by revenue, their retention history, and relationship strength. Concentration risk is the single biggest valuation reducer. If your top 3 customers represent more than 30% of revenue, you need a plan to demonstrate stability.

Valuation: What Multiple Should You Expect in Michigan

Security services companies with strong recurring revenue and low customer churn (under 15% annually) typically sell for 4.5-6.5x EBITDA in the Midwest market. Monitoring-focused businesses and integrated systems companies trend toward the higher end. Mobile patrol and event-based security sit lower, around 3.5-4.5x. Michigan-based deals have performed in line with or slightly below national averages over the past two years, primarily because buyer activity concentrates in larger metros like Detroit, Grand Rapids, and Ann Arbor. If your business has annual revenue under $1 million, expect the lower end of that range. Conversely, if you have gross margins above 75%, retention above 90%, and a management team that can operate without you, you're competitive for 5.5-6.5x. Michigan's state income tax (4.25%) and overall business cost structure don't materially affect deal multiples the way they do in California or New York, but they do influence buyer cost of capital and willingness to invest in organic growth post-acquisition. For context, a $1.5 million EBITDA security company would realistically fetch $6.75-9.75 million in today's Michigan market, depending on the factors above.

The Selling Process, Step by Step

• Month 1-2: Prepare financials and documentation. Have your accountant prepare three years of tax returns and normalized EBITDA calculations. Compile your customer list, contracts, and operational procedures. This stage often takes longer than sellers expect.
• Month 2-3: Engage an M&A advisor or broker. You'll want someone with demonstrable relationships to search funds, regional PE, and strategic buyers active in Michigan. They should prepare a confidential information memorandum (CIM) highlighting your revenue quality, margins, and growth trajectory. This is not a generic business plan; it's a sales document.
• Month 3-4: Market your business. Your advisor will conduct outreach to 20-40 qualified buyers. In Michigan's market, expect 15-25% response rates from genuine prospects. Poor responses often signal that your asking price is misaligned with market reality.
• Month 4-6: Diligence and negotiation. Serious buyers will request detailed financial records, customer contracts, compliance documentation, and management references. Parallel to this, legal counsel will negotiate a letter of intent (LOI). Michigan deals typically move slower than coasts, so assume 8-12 weeks for this phase.
• Month 6-9: Final due diligence and purchase agreement drafting. Buyers will conduct deeper financial, legal, and operational diligence. Environmental concerns (if you have a facility) and any compliance issues emerge here. This is where most deals either firm up or fail.
• Month 9-12: Closing. Closing typically takes 4-6 weeks in Michigan. Ensure your legal counsel reviews the purchase agreement thoroughly, especially earn-out structures and indemnification provisions. Most Michigan deals include seller representations and warranties insurance to protect against post-close claims.
• Post-close: Transition period (typically 30-90 days). You'll work with the buyer to ensure customer continuity, staff retention, and operational handoff. Some deals include earnout provisions tied to customer retention or revenue performance during this window.

Common Mistakes Sellers in Michigan Make

• Waiting too long to professionalize financials. If your books are held together with personal spreadsheets and loose invoicing, you'll lose 6-12 months of the selling timeline just getting audit-ready. Start cleaning up 12-18 months before you plan to market.
• Overestimating customer stickiness. Sellers often assume their customer relationships will survive a change in ownership. If you have no signed contracts or if your retention is driven by personal relationships rather than service quality, disclose it upfront. Buyers will discover this in diligence and reprice your deal downward.
• Pricing based on revenue, not EBITDA. A common trap: comparing your revenue to other sales and anchoring to that number. Michigan buyers care only about sustainable, normalized profit. A $5 million revenue business with 18% EBITDA margins is worth significantly less than a $3 million revenue business with 40% margins.
• Staying hidden during buyer outreach. Some sellers resist introducing themselves to potential acquirers, fearing information leaks or disruption. In reality, buyers want to meet strong operators. Your absence signals weakness. Be willing to participate in calls with serious prospects.
• Underinvesting in legal counsel. Security businesses operate under state licensing, customer contracts, and sometimes compliance obligations. Poor contract language or missing compliance documentation will create post-close clawbacks or failed earnouts. Spend 2-3% of deal value on experienced legal review.
