Know exactly what to verify before buying a generator dealer — from OEM authorization transferability to the true quality of recurring maintenance contract revenue.
Find Generator Sales & Service Acquisition TargetsGenerator sales and service businesses offer attractive recurring revenue and recession resistance, but hidden risks around OEM dealer authorizations, technician dependency, and lumpy storm-driven revenue can destroy post-close value. This guide walks buyers through the three critical due diligence phases specific to this industry.
Validate the true composition of revenue across installation, service contracts, and parts — and separate recurring from event-driven income before accepting any stated EBITDA figure.
Break out installation, maintenance agreements, warranty work, parts, and emergency calls by year. Identify what percentage is recurring versus storm-driven. Target 30%+ from maintenance contracts.
Request contract-level data on active service agreements including annual value, renewal dates, and 3-year retention rates. High churn signals weak customer relationships or poor service quality.
Identify personal vehicle expenses, above-market owner salary, and one-time costs. Generator businesses often have significant owner perks embedded in operating expenses that require careful normalization.
Authorized dealer and warranty service status with Generac, Kohler, or Cummins is a core value driver. Confirm these agreements are transferable and not at risk of lapsing post-close.
Request all dealer and warranty service agreements with Generac, Kohler, Cummins, or Briggs & Stratton. Verify transfer clauses, volume minimums, and whether OEM approval is required at close.
Confirm supplier relationships supporting parts access during peak demand periods. Evaluate inventory levels, aging stock, and whether storm-season equipment allocation is tied to the current owner's relationships.
Confirm all active technician certifications required to maintain dealer and warranty service status. Lapses can trigger OEM authorization loss — a deal-breaking post-close risk.
Generator service businesses are frequently owner-dependent. Assess whether technicians, customer relationships, and dispatch operations can survive an ownership transition without revenue erosion.
Identify which commercial and residential accounts are personally managed by the seller. Plan for structured introductions and retention strategies before close if key accounts follow the owner.
Review technician employment history, compensation, non-compete agreements, and any informal retention arrangements. Losing even one senior tech can limit capacity and OEM authorization status.
Confirm customer asset data, service history, and contract details are documented in a service management platform. Paper-based records signal operational fragility and complicate post-close integration.
Not automatically. Most OEM agreements require written notice and manufacturer approval for ownership transfers. Some impose volume or certification thresholds. Engage the OEM directly during due diligence, not after close.
Apply a higher multiple to recurring maintenance contract revenue and a lower multiple to one-time installation income. A business with 40%+ recurring revenue typically commands 4.5–5.5x EBITDA versus 3.5x for installation-heavy operators.
You risk losing OEM authorization if certified technicians depart, reducing warranty work eligibility and customer confidence. Negotiate retention bonuses funded at close and require seller cooperation on technician introductions during transition.
Yes. Generator service businesses are SBA-eligible and well-suited for 7(a) financing given tangible assets and recurring revenue. Expect to inject 10–20% equity, with lenders scrutinizing contract retention and OEM authorization stability post-close.
