Letter of Intent Template for Acquiring a Plumbing Business

Parties and Transaction Overview

Identifies the buyer entity, seller entity, and the legal structure of the proposed transaction. In plumbing acquisitions, buyers almost universally structure deals as asset purchases rather than stock purchases to avoid inheriting hidden liabilities such as open permits, prior code violations, undisclosed insurance claims, or unlicensed work performed under the seller's contractor license.

💡 Sellers in plumbing businesses are often sole proprietors or single-member LLCs and may initially push back on asset vs. stock structure due to tax implications. Buyer should be prepared to discuss a modest price allocation adjustment to compensate for the seller's higher capital gains exposure, but should not concede on asset purchase structure given the license, permit, and liability risks inherent in plumbing operations. Clarify early whether the trade name and phone number — often the most valuable customer-facing assets — are owned by the entity or personally by the owner.

Proposed Purchase Price and Consideration

States the total enterprise value being offered, the proposed payment structure, and how consideration will be allocated between cash at close, a seller note, and any earnout component. Plumbing deals in the $1M–$5M revenue range typically trade at 3x–5.5x EBITDA. The structure of consideration is heavily influenced by whether the buyer is using SBA financing, private equity capital, or a combination.

💡 In SBA-financed deals, the seller note is typically required to be on full standby for the first 24 months. Be transparent with the seller about this restriction early — surprises here kill deals. For PE platform acquisitions, consider structuring a 12–24 month earnout tied to EBITDA or revenue retention to bridge valuation gaps, particularly if a meaningful portion of revenue is attributable to the owner's personal relationships. Tie any earnout to metrics the seller can directly influence post-close, such as retained service contract revenue or gross margin on residential service calls.

Working Capital and Net Working Capital Peg

Defines the expected working capital to be delivered at closing and the mechanism for post-close adjustment. This section is particularly important in plumbing businesses, where seasonal billing cycles, large material deposits on commercial projects, and slow-paying commercial accounts receivable can cause significant working capital swings.

💡 Many plumbing business owners do not track working capital in a formal way and may not understand the NWC peg concept. Budget time during due diligence to educate the seller or their CPA on how this works. Watch for commercial customers with slow payment terms — net 45 or net 60 is common in commercial plumbing — that could artificially inflate receivables close to the measurement date. Also confirm whether the seller has pre-collected deposits on active jobs that will become the buyer's obligation to perform post-close.

Assets Included and Excluded

Explicitly lists what is and is not being purchased. This section prevents disputes about which vehicles, tools, equipment, and customer relationships are part of the deal. In plumbing acquisitions, the service van fleet, branded equipment, and transferable customer contracts are core assets. Personal vehicles, real estate, and owner retirement accounts are universally excluded.

💡 Fleet condition is one of the most common post-LOI deal disruptors in plumbing acquisitions. Request a complete fleet schedule with year, make, model, mileage, and maintenance history for every vehicle before signing the LOI if possible. If the seller has deferred vehicle maintenance or has vans approaching end of useful life, negotiate a fleet credit or price reduction rather than discovering this mid-due-diligence. Confirm that all vehicles are titled in the business name, not personally — retitling vehicles out of a personal name adds time and SBA compliance complexity.

Due Diligence Period and Access

Establishes the length of the due diligence period and the seller's obligations to provide access to financial records, operational data, employee information, license documentation, and customer data. In plumbing transactions, due diligence typically runs 45–75 days due to the complexity of license verification, fleet assessment, and financial restatement.

💡 Sellers are often nervous about employees learning the business is for sale — this is especially sensitive in plumbing where technician poaching is a real risk. Agree upfront that employee and customer-facing due diligence will be conducted confidentially, and that the buyer will not contact employees directly without seller consent until a definitive agreement is signed. For license verification, contact the relevant state plumbing licensing board directly — do not rely solely on copies provided by the seller. Verify that master plumber and contractor licenses are in the entity's name or are transferable, not solely tied to the owner personally.

Exclusivity and No-Shop Period

Grants the buyer an exclusive negotiating period during which the seller agrees not to solicit or entertain competing offers. This is one of the most critical sections in the LOI for the buyer, as it prevents the seller from using the LOI to create a competitive auction after the buyer has invested in due diligence.

💡 Some sellers represented by business brokers will push to limit the exclusivity period to 30 days. For a plumbing business requiring license verification, fleet inspection, financial restatement, and SBA lender review, 30 days is typically insufficient. Push for 60 days and agree to provide the seller with a weekly due diligence status update to demonstrate momentum. If the seller insists on 45 days, accept it but ensure you have your SBA lender and QoE provider engaged within the first week of signing.

Conditions to Closing

Lists the material conditions that must be satisfied before the buyer is obligated to close. In plumbing acquisitions, conditions specific to licenses, key employee retention, and insurance continuity are critical additions to the standard closing conditions found in generic LOI templates.

💡 The license transfer condition is non-negotiable and must be addressed in the LOI, not deferred to the definitive agreement. In many states, plumbing contractor licenses are issued to individuals (qualifying agents) rather than business entities. If the seller is the qualifying agent and is exiting the business, the buyer must either hold their own master plumber license, hire a qualifying agent before close, or structure a post-close period during which the seller remains as qualifying agent on a contracted basis. Clarify this with the relevant state licensing board before finalizing the LOI.

Seller Transition and Non-Compete

Outlines the seller's post-close involvement in the business and the scope of any non-competition and non-solicitation restrictions. In plumbing businesses where the owner is the primary customer relationship holder and often the master license holder, the transition period and non-compete are among the most value-protective terms in the deal.

💡 Non-compete enforceability varies significantly by state — confirm applicable state law before inserting specific mileage and duration terms. Courts in some states will not enforce non-competes beyond 2–3 years, so work with local counsel to set realistic parameters. For PE platform acquisitions with an earnout, the non-compete and earnout periods should be coterminous to avoid perverse incentives. Consider including a carve-out allowing the seller to perform plumbing work personally if they hold a master license, as long as it is outside the defined radius and does not involve soliciting current customers or employees.

Confidentiality

Obligates both parties to maintain the confidentiality of deal terms, financial information, and customer data exchanged during the transaction process. In plumbing, confidentiality is especially important to protect employee relations, customer relationships, and competitive positioning during the sale process.

💡 The seller's employees — particularly licensed plumbers — are a flight risk if word gets out that the business is for sale. Technician poaching by competing plumbing companies is a documented pattern in trades M&A. Keep the circle of knowledge tight. If the seller must involve their bookkeeper or office manager in compiling financial documents for due diligence, address this with the seller directly and consider offering key employee retention bonuses as part of the deal structure to reduce flight risk.
