How to Sell Your Security Alarm Business

Monthly recurring revenue (MRR) is contracted monitoring income that repeats each month, and buyers value it because it makes cash flow predictable and reduces reliance on new installs. Higher MRR and lower churn typically increase the EBITDA multiple and support a higher offer price and better deal terms. For security alarm companies, buyers often pay a premium when 70%+ of revenue is recurring and net subscriber attrition is under 10% annually. Improve this by moving customers to longer-term monitoring agreements and tightening service to reduce cancellations before going to market.

Pye-Barker security side added Priority One SC and Sonitrol / Secure Pacific in 2025 ¹², Securitas Technology, and Convergint price the RMR book per account with attrition as the discount factor ³. Pye-Barker ranks #4 on the SDM 100 — the definitive ranking of the nation's largest security integrators ⁴. R2 data quantifies recurring revenue above 50% at +1.0×–2.5× EBITDA lift — and security RMR is the cleanest case in the manifest (purely subscription with low marginal cost to serve) ⁶.

Customer attrition rate measures how often monitoring customers cancel, and buyers focus on it because recurring revenue is only as valuable as its retention. Higher churn reduces predictable cash flow and contract value, lowering multiples or prompting holdbacks and earnouts. In a security alarm business, monthly churn under ~1% (annual under ~12%) is typically viewed as strong, while 2%+ monthly raises red flags. Reduce attrition by tightening service response times, improving communication, and extending contract terms before a sale.

R3 §4 cites <8%/yr as the buyer-preferred premium threshold; above 10% triggers earnouts; above 12% can deal-kill or force RMR-based earnouts at 5–10% per R3 buyer structure ³. IBBA Market Pulse Q3 2025 confirms the same attrition dynamic in subscription-service valuations — attrition above the category median compresses multiples by 0.5×–1.5× ⁷. Every percentage point of attrition matters in the per-account underwriting math.

Contract length and terms define how long customers are committed and what pricing, renewal, and cancellation rights apply, which buyers value for predictable cash flow. Longer, enforceable terms with favorable escalators typically support a higher multiple and reduce holdbacks tied to churn risk. In a security alarm business, multi-year monitoring agreements (e.g., 36–60 months) with 3–5% annual increases and clear auto-renewal language are viewed more positively than month-to-month plans. Standardize contracts, tighten cancellation clauses, and document renewal rates before going to market.

R2 §LIFT #15 quantifies long-term contracts at +0.5×–1.5× EBITDA lift ⁶. Buyers will audit every contract in diligence — standardizing on a single enforceable template before close removes a common pricing discount.

Monitoring infrastructure includes your central station arrangement, redundancy, and automation, and buyers care because it drives uptime, compliance, and recurring revenue retention. Strong, scalable infrastructure reduces risk and supports higher RMR multiples and better offer terms. For a security alarm company, buyers often expect UL-listed monitoring with dual-path communications, documented disaster recovery, and less than 1% monthly attrition. Improve this by upgrading redundancy, tightening SLAs, and documenting testing and incident response.

UL-listed central station (operated in-house or via a UL-listed wholesale partner) is the floor for institutional buyers such as Securitas Technology and Convergint ³. Insurance carriers and commercial property managers require UL listing for monitored alarm credit — it is a non-negotiable prerequisite for the enterprise commercial buyer pool.

Owner dependency measures how much daily operations, sales, and customer relationships rely on you, and buyers care because it increases transition risk. Higher dependency typically reduces the multiple or leads to holdbacks and longer earn-outs. For a security alarm business, if you personally handle most service dispatching and 30%+ of renewals or upsells, buyers will discount the price. Reduce this by documenting processes, delegating to a GM/service manager, and locking customers into contracts handled by a team.

The same R2 §DRAG #1 mechanic as fire protection applies: owner running sales, holding installer license, or being the primary account contact triggers a 1.0×–2.0× EBITDA discount ⁶. Hire or promote a GM and service manager 12–18 months before close, route customer relationships through them, and document succession.

Recurring revenue and customer concentration show buyers your security alarm business will produce predictable cash flow with low churn risk. Higher recurring monthly revenue and longer contract duration typically increase EBITDA multiples and reduce holdbacks. For example, buyers often pay more when 70%+ of revenue comes from monitored services and annual attrition is under 10%. Improve this by moving customers to multi-year monitoring agreements and tightening cancellation and collections processes before sale.

R3 §4 explicitly cites enterprise account mix as a premium driver ³. Customer concentration above 20% in any single account compresses multiples by 0.5×–1.0× in security integrator underwriting ⁸. Multi-location commercial accounts (REITs, hospitals, retailers, light industrial) churn slower than residential, drive higher RMR per account, and unlock the Securitas Technology / Convergint buyer pool. Residential-heavy books with high churn cap out at the lower-mid multiple band.
