From SBA-backed acquisitions to seller notes tied to contract retention — understand the deal structures that close in this seasonal, recurring-revenue trades business.
Acquiring or selling an irrigation installation business requires deal structures that account for the industry's unique dynamics: pronounced seasonality, recurring maintenance contract value, technician key-man risk, and equipment-heavy balance sheets. Most transactions in the $1M–$5M revenue range are structured as asset purchases, allowing buyers to cherry-pick contracts, equipment, and customer relationships while leaving behind unknown liabilities. SBA 7(a) financing is the dominant capital source for qualified buyers, often covering 80–90% of the purchase price with the remainder filled by seller notes or equity rollover. Earnouts tied to seasonal revenue targets or maintenance contract retention are frequently used to bridge valuation gaps — especially when a significant portion of revenue flows from the owner's personal relationships with landscapers, HOA property managers, or home builders. Understanding which structure fits your scenario — whether you're a first-time buyer, a landscaping operator adding irrigation, or a seller retiring after 20 years — is critical to getting a deal done and keeping it together post-close.

The most common structure for irrigation business acquisitions in the lower middle market. An SBA 7(a) loan finances 80–90% of the purchase price, with the seller retaining 10–20% equity in the business for a defined transition period — typically 12–24 months. The equity rollover demonstrates seller confidence in the business to SBA lenders and aligns the seller's incentives with a successful ownership transition, particularly critical when customer relationships are tied to the outgoing owner.
Pros
Cons
Best for: First-time buyers or search fund operators acquiring an established irrigation business with $300K+ SDE, strong recurring maintenance revenue, and a seller willing to remain engaged during transition.
Asset Purchase with Seller Note Tied to Contract Retention
The buyer acquires specified business assets — customer contracts, equipment fleet, vehicles, trade name, and licenses — rather than the legal entity. A seller note of 10–20% of the purchase price is structured with repayment contingent on retention of recurring maintenance contracts over a 12–24 month post-close period. If key service accounts cancel within the retention window, the outstanding note balance is reduced proportionally, protecting the buyer from paying full price for revenue that doesn't transfer.
Pros
Cons
Best for: Buyers acquiring irrigation businesses where a meaningful share of revenue comes from commercial accounts, HOAs, or property management relationships that may be relationship-dependent rather than contractually locked.
Full Cash Acquisition with Performance-Based Earnout
A well-capitalized buyer — typically a PE-backed outdoor services roll-up or a landscaping operator using balance sheet cash — pays a negotiated base price at closing with an additional earnout payment tied to the irrigation business hitting seasonal revenue or EBITDA targets in year one or two post-close. This structure allows buyers to pay a competitive headline price while deferring a portion of consideration until the business proves it can perform under new ownership during at least one full seasonal cycle.
Pros
Cons
Best for: PE-backed platforms or landscaping operators executing roll-up strategies where integration speed matters, or acquisitions where the seller has strong growth trajectory evidence that justifies a premium purchase price.

Asset purchases allow buyers to acquire only specified contracts, equipment, licenses, and customer relationships without inheriting the seller's legal entity and its unknown liabilities — including unresolved warranty claims, permit violations, or undisclosed tax obligations. For irrigation businesses, this is especially important because regulatory compliance around backflow prevention, contractor licensing, and municipal permits varies significantly by jurisdiction, and liability exposure from prior installation work can surface years after a job is completed.
SBA 7(a) loans are the primary financing vehicle for irrigation business acquisitions under $5M in purchase price. Lenders will require 3 years of business tax returns, a clear SDE or EBITDA add-back schedule, evidence of transferable contractor licenses, and a demonstration that the business generates sufficient cash flow to service debt — typically a minimum 1.25x debt service coverage ratio. Lenders will scrutinize cash revenue, personal expense commingling, and revenue concentration. A business where 60%+ of revenue comes from one HOA or builder will face more underwriting friction than one with a diversified residential and commercial base.
A seller note is a loan from the seller to the buyer that finances a portion of the purchase price — typically 10–20% — and is repaid over 24–60 months with interest. Sellers agree to carry notes for several reasons: it demonstrates confidence in the business to SBA lenders (often required), it can generate higher effective sale proceeds through interest income, and it creates a financial incentive for the seller to actively support the transition. For buyers, seller notes tied to customer contract retention are a risk management tool — if key accounts don't transfer, the outstanding note balance is reduced proportionally.
Earnouts in irrigation acquisitions are typically tied to year-one or year-two seasonal revenue or EBITDA targets, paid in one or two tranches after the close. Common disputes arise around weather-related revenue shortfalls (a drought or early winter season can suppress installation and maintenance revenue through no fault of either party), post-close operational changes by the buyer that reduce revenue, and disagreements about which revenue counts toward earnout thresholds — particularly for new accounts added under new ownership. Well-drafted earnout agreements define revenue measurement periods aligned with seasonal cycles (April–October for most markets), exclude buyer-initiated changes from performance calculations, and include a dispute resolution mechanism.
Contractor license transferability varies significantly by state. In many jurisdictions, an irrigation contractor license is issued to an individual — not the business entity — meaning the buyer must either hold their own qualifying license or hire a licensed qualifier before operating post-close. Backflow prevention and cross-connection control certifications are similarly individual-held in most states. Buyers should conduct license due diligence during the LOI period and include license transfer or buyer licensure as a condition precedent to close. Failure to address this pre-close can result in the buyer being unable to legally operate the business from day one.
Most experienced buyers target a minimum of 30% recurring revenue from annual service contracts — covering winterization, spring startup, and ongoing maintenance — before seriously pursuing an acquisition. Businesses at 40–50%+ recurring revenue command premium multiples (4.5x–5.5x SDE) because they provide predictable cash flow that services acquisition debt even during slow installation seasons. Businesses with 70%+ of revenue tied to one-time new construction installs are harder to finance, command lower multiples (3x–3.5x SDE), and carry higher earnout or seller note provisions to protect buyers against project pipeline variability.
