Letter of Intent Template for Acquiring an Engineering & Surveying Firm

A field-ready LOI guide built for the unique complexities of licensed professional services acquisitions — covering license transfer contingencies, backlog earnouts, E&O tail coverage, and key-man retention clauses.

Acquiring an engineering or surveying firm is fundamentally different from buying a standard service business. State licensing boards regulate who can own and operate a firm with a licensed PE or PLS principal, contracts are frequently non-assignable without client consent, and a significant portion of enterprise value sits in backlog that may never convert to revenue. A well-drafted Letter of Intent must address these realities before either party invests in full due diligence. This guide walks buyers and sellers through each section of a professionally structured LOI, with example language tailored to civil engineering and land surveying transactions in the $1M–$5M revenue range. Whether you are an SBA-financed first-time buyer, a regional roll-up platform, or a retiring PE or PLS principal, the terms outlined here will protect your position and accelerate a clean path to closing.

LOI Sections for Engineering & Surveying Firm Acquisitions

Parties and Transaction Structure

Identifies the buyer entity, seller entity, and the legal structure of the proposed transaction — asset purchase or stock purchase. For engineering and surveying firms, asset purchases are more common because they allow buyers to exclude unknown liabilities such as unresolved E&O claims, but stock purchases may be preferred when client contracts and government authorizations are difficult to assign.

Example Language

This Letter of Intent is entered into between [Buyer Entity Name], a [State] [LLC/Corporation] ('Buyer'), and [Seller Entity Name], a [State] [Professional Corporation/LLC] ('Seller'), and [Founding Principal Name], PE/PLS ('Principal'). Buyer proposes to acquire substantially all of the assets of Seller used in connection with the civil engineering and land surveying business operated under the name [Firm Name], including all equipment, survey instruments, software licenses, client contracts, project backlog, GIS and CAD data archives, and goodwill. The transaction is contemplated as an asset purchase. Stock purchase structure may be considered by mutual agreement if required for the assignment of specific municipal on-call contracts or government authorizations.

💡 Sellers should push for stock purchase if the firm holds government contracts or state DOT pre-qualification certifications that are not assignable under an asset deal without agency consent. Buyers should resist stock purchase unless they have thoroughly reviewed E&O history, open project claims, and all outstanding liabilities. In either case, identify early whether any key municipal or retainer contracts contain change-of-control provisions requiring client notification or consent.

Purchase Price and Valuation Basis

States the proposed total consideration, the EBITDA multiple or methodology used to derive it, and how owner compensation adjustments, discretionary add-backs, and backlog were factored into the valuation. Engineering and surveying firms in the lower middle market typically trade at 3.5x–6x adjusted EBITDA, with premium multiples reserved for firms with diversified client bases, multiple licensed staff, and strong contracted backlog.

Example Language

Buyer proposes a total enterprise value of $[X,XXX,000], representing approximately [4.5x] Seller's trailing twelve-month adjusted EBITDA of $[XXX,000], as calculated by Buyer based on Seller's 2021–2023 financial statements and owner compensation normalization. This valuation assumes a backlog of contracted, billable work of no less than $[X,XXX,000] as of the anticipated closing date, verified by executed client agreements and purchase orders. The purchase price is subject to final adjustment following completion of financial and operational due diligence, including independent verification of backlog, work-in-progress billing, and accounts receivable aging.

💡 Sellers should provide a detailed backlog schedule broken down by client, contract type (fixed-fee vs. time-and-materials), and projected billing timeline before LOI execution to anchor valuation. Buyers should build a backlog haircut into the model — typically 10–20% — to account for scope changes, cancellations, and delayed project starts that are common in land development and infrastructure work. Avoid agreeing to a firm purchase price in the LOI without a clear mechanism for post-close true-up based on verified backlog at closing.

Deal Structure and Payment Terms

Outlines how the total consideration is allocated across cash at close, seller financing, SBA debt, and any earnout components. Most engineering and surveying firm acquisitions in the lower middle market use a combination of SBA 7(a) financing, a seller note, and a performance-based earnout tied to revenue retention or backlog conversion to manage key-man and client attrition risk.

Example Language

The proposed consideration of $[X,XXX,000] shall be structured as follows: (i) $[X,XXX,000] in cash at closing, funded through SBA 7(a) financing (approximately [80%]) and Buyer equity contribution (approximately [10–15%]); (ii) a Seller Note in the amount of $[XXX,000] bearing interest at [6%] per annum, payable over [36] months, subordinated to SBA lender requirements; and (iii) an earnout of up to $[XXX,000] payable over [24] months post-closing, contingent upon (a) retention of at least [75%] of trailing twelve-month revenue from clients identified in Exhibit A, and (b) conversion of no less than [60%] of the closing-date backlog schedule into billed revenue within [18] months of closing.

💡 Sellers should negotiate earnout metrics that are within their direct control during the transition period — specifically revenue retention tied to their own client introductions rather than new business development by the buyer. Buyers using SBA financing should confirm with their lender that the seller note structure is compliant with SBA standby requirements, as SBA 7(a) rules typically require seller notes to be on full standby for the first 24 months. Earnout calculations should be agreed upon with clearly defined accounting methodology to avoid post-close disputes.

Professional Licensing Contingency

Addresses the critical condition that the transaction is contingent upon the buyer's ability to satisfy state professional licensing board requirements for firm ownership, including identification of a licensed PE or PLS who will serve as the responsible principal post-closing. This is among the most deal-specific contingencies in engineering and surveying acquisitions and must be addressed in the LOI, not deferred to the purchase agreement.

Example Language

The obligations of Buyer under this Letter of Intent and any subsequent definitive agreement are expressly contingent upon: (i) Buyer's confirmation, within [30] days of the execution of this LOI, that the proposed post-closing firm structure satisfies all applicable requirements of the [State] Board of Professional Engineers and Land Surveyors for licensed engineering and surveying firm ownership; (ii) identification of a licensed Professional Engineer (PE) and/or Professional Land Surveyor (PLS) who will serve as the responsible principal-in-charge of licensed services following closing, acceptable to the relevant state licensing board; and (iii) receipt of any required board approvals, firm re-registration filings, or certificate of authorization amendments prior to or contemporaneously with closing. Seller agrees to cooperate fully with Buyer in any required board filings or notifications during the due diligence period.

💡 This contingency protects buyers from closing into a firm they legally cannot operate. Sellers should validate their own state's rules before listing — some states require that a majority owner hold a professional license, while others permit non-licensed ownership with a designated licensed principal. In states with strict ownership requirements, buyers who are not licensed engineers or surveyors may need to structure a phased equity acquisition or retain the founding principal as a licensed officer during a multi-year transition. Engage a licensed attorney familiar with the applicable state engineering board rules before finalizing LOI language.

Transition and Seller Retention Period

Defines the post-closing role of the founding principal or key licensed staff, including the duration, compensation, and scope of the transition consulting or employment arrangement. In engineering and surveying firm acquisitions, a 2–3 year seller transition period is strongly preferred by buyers and lenders to protect client relationships and maintain licensed signatory capacity during the integration period.

Example Language

As a material condition of the proposed transaction, Seller and Principal agree to remain actively engaged with the business following closing for a period of no less than [24] months under a mutually agreed Employment or Consulting Agreement, at an annual compensation rate of $[XXX,000], to be negotiated in good faith prior to closing. During the transition period, Principal shall: (i) maintain their active PE/PLS license in good standing and continue serving as the responsible principal-in-charge where required by state board rules; (ii) introduce Buyer's designated successor principal to all active municipal, DOT, and retainer clients; (iii) support the conversion of backlog projects currently in progress; and (iv) provide no fewer than [40] hours per month of active client-facing and project supervision support. The transition arrangement shall be documented in a separate Employment or Consulting Agreement executed simultaneously with the definitive Purchase Agreement.

💡 Sellers should negotiate transition compensation separately from the purchase price to avoid confusion about what is being paid for business value versus ongoing services. Buyers should include performance expectations in the transition agreement — not just availability — to ensure meaningful client handoff occurs. SBA lenders may require the seller's transition period to align with the earnout window, so coordinate with the lender early when structuring these parallel agreements.

Exclusivity and No-Shop Period

Establishes a defined period during which the seller agrees not to solicit, entertain, or negotiate with other prospective buyers while the buyer conducts due diligence and works toward a definitive agreement. Standard exclusivity periods in lower middle market professional services transactions run 45–90 days.

Example Language

In consideration of Buyer's commitment to proceed with due diligence and incur related costs, Seller and Principal agree that for a period of [60] days following the execution of this Letter of Intent (the 'Exclusivity Period'), neither Seller, Principal, nor any agent, broker, or representative acting on their behalf shall directly or indirectly solicit, encourage, initiate, or participate in discussions or negotiations with any third party regarding the potential sale, merger, recapitalization, or other disposition of the business or its assets. Seller shall promptly notify Buyer if Seller receives any unsolicited inquiry from a third party during the Exclusivity Period. The Exclusivity Period may be extended by mutual written agreement of the parties for up to an additional [30] days if due diligence is substantially complete and the parties are actively negotiating a definitive agreement.

💡 Sellers should resist exclusivity periods longer than 60 days without a clear milestone schedule tied to buyer deliverables, such as completion of QoE review, financing commitment, and draft purchase agreement delivery. Buyers using SBA financing should be realistic about their timeline — SBA lender approval alone can take 30–45 days — and request a 90-day exclusivity period with automatic extension provisions. If the seller is working with a sell-side advisor, the advisor may push to limit exclusivity until after a management meeting or QoE kickoff is confirmed.

Due Diligence Scope and Access

Outlines the categories of information the buyer requires access to during the due diligence period and the seller's obligations to provide timely, accurate documentation. For engineering and surveying firms, due diligence must specifically address E&O insurance history, professional license status, backlog verification, contract assignability, and key employee compensation.

Example Language

Following execution of this LOI and a mutually executed Non-Disclosure Agreement, Seller agrees to provide Buyer and its advisors with reasonable access to the following categories of information within [10] business days: (i) three years of compiled, reviewed, or audited financial statements and federal tax returns (2021–2023), including work-in-progress schedules and accounts receivable aging; (ii) all active client contracts, master service agreements, government on-call contracts, and retainer arrangements, with identification of any change-of-control or assignment restrictions; (iii) backlog schedule as of the LOI execution date, itemized by project, client, contract type, and estimated billing timeline; (iv) Errors & Omissions and general liability insurance certificates, five-year claims history, and information regarding tail coverage availability and cost; (v) current PE, PLS, and firm licensure certificates for all states in which Seller performs licensed services; (vi) organization chart, employee roster, compensation schedules, and existing employment or non-compete agreements; and (vii) a schedule of all material equipment, vehicles, survey instruments, software licenses, and proprietary data assets including GIS databases and historical survey archives.

💡 Sellers should organize due diligence materials into a virtual data room before the LOI is signed to reduce friction and demonstrate transaction readiness. Particular attention should be paid to E&O insurance documentation — buyers and their lenders will scrutinize claims history closely, and any open claims or circumstances reported to the insurer must be disclosed proactively. Buyers should engage a Quality of Earnings (QoE) provider with professional services experience to independently verify EBITDA adjustments and backlog recoverability before committing to a firm purchase price.

Confidentiality and Non-Solicitation

Confirms that both parties are bound by confidentiality obligations and restricts the buyer from directly soliciting the seller's employees or clients during and after the due diligence period, regardless of whether the transaction closes.

Example Language

Each party acknowledges that information shared pursuant to this LOI and the due diligence process is proprietary, confidential, and commercially sensitive. Buyer agrees that it shall not, for a period of [24] months following the termination of this LOI or any subsequent definitive agreement, directly solicit for employment any licensed engineer, surveyor, project manager, or other key employee of Seller identified during the due diligence process, nor directly solicit any client of Seller whose identity was disclosed through the due diligence process, unless such contact arises through a general public advertisement not specifically directed at Seller's employees or clients. These obligations supplement and do not replace the parties' obligations under any separately executed Non-Disclosure Agreement.

💡 Sellers with highly specialized licensed staff — particularly PE or PLS signatories — should negotiate aggressive non-solicitation terms to protect against a failed deal that leaves their best employees vulnerable to recruitment by a buyer who walked away. Buyers should ensure that non-solicitation language carves out employees who independently approach the buyer after the deal falls through, to avoid overreach.

Binding vs. Non-Binding Provisions

Clearly distinguishes which provisions of the LOI create legally enforceable obligations and which are non-binding expressions of intent, subject to negotiation and execution of a definitive purchase agreement.

Example Language

The parties acknowledge and agree that this Letter of Intent is intended to summarize the parties' current understanding of the proposed transaction and does not constitute a legally binding agreement to consummate the acquisition, except with respect to the following provisions, which shall be legally binding upon execution: (i) the Exclusivity and No-Shop obligations set forth in Section [6]; (ii) the Confidentiality and Non-Solicitation obligations set forth in Section [8]; and (iii) each party's obligation to bear its own costs and expenses incurred in connection with this LOI and the due diligence process, unless otherwise agreed in a definitive agreement. All other provisions of this LOI, including the proposed purchase price, deal structure, earnout terms, and transition arrangements, are non-binding expressions of intent subject to completion of due diligence, negotiation of a definitive purchase agreement, and satisfaction of all conditions to closing.

💡 Both parties should have independent legal counsel review the binding provisions before signing. Buyers should ensure that the break-fee or cost-bearing provisions are clearly non-binding unless they intend to commit to a specific remedy if they terminate the deal without cause after due diligence has begun. Sellers who have invested significantly in deal preparation — including QoE readiness and broker fees — may negotiate for a reverse break fee if the buyer terminates without a legitimate due diligence finding.

Key Terms to Negotiate

Backlog Verification Methodology

How contracted backlog is measured, verified, and used to adjust purchase price at closing is one of the most consequential negotiation points in an engineering firm acquisition. Buyers and sellers must agree in advance on whether backlog includes only executed contracts, also counts awarded but unsigned projects, or extends to pipeline opportunities. A clear definition prevents post-close disputes and ensures earnout metrics are grounded in verifiable data rather than optimistic projections.

Earnout Revenue Retention Baseline

The baseline revenue figure used to calculate post-close earnout payments must be carefully defined. If the founding principal's direct client relationships generate 60% of revenue, the earnout baseline should reflect only revenue the seller can realistically influence during the transition period — not total firm revenue that includes new business developed by the buyer. Misaligned earnout baselines are a leading cause of post-close litigation in professional services acquisitions.

E&O Tail Coverage Responsibility

Errors and Omissions tail coverage protects against claims arising from pre-closing work that are reported after the policy period ends. In engineering and surveying transactions, the cost of tail coverage — which can range from 150% to 300% of the annual premium — must be clearly allocated between buyer and seller in the LOI and Purchase Agreement. Buyers typically require the seller to purchase tail coverage at their expense as a condition of closing, but this point is negotiable and should be addressed early.

Non-Compete Scope and Geography

Non-compete agreements with the founding principal are standard in engineering firm acquisitions but must be carefully scoped. A non-compete that is too broad — prohibiting the seller from any engineering-related work in a five-state region for five years — may be unenforceable in certain states and can create resentment that undermines the transition relationship. Agreements scoped to the firm's actual service territory and limited to direct competitive solicitation of existing clients are more defensible and more likely to be honored.

Client Contract Assignment Consent Process

Many government on-call contracts, master service agreements, and municipal retainer arrangements contain anti-assignment provisions or require client consent for ownership changes. The LOI should establish who is responsible for obtaining assignment consents — typically the seller, with buyer cooperation — and what happens to the purchase price if key contracts representing more than a threshold percentage of revenue cannot be assigned or consented to before closing. This is particularly critical for state DOT pre-qualification certifications and federal agency authorizations.

Key Employee Retention Incentives

The value of an engineering or surveying firm depends heavily on its licensed technical staff. The LOI should contemplate retention packages or stay bonuses for licensed engineers, surveyors, and project managers that the buyer considers essential to continued operations. These arrangements are typically funded by the buyer but may reduce the seller's net proceeds if structured as a purchase price credit. Identifying and protecting key employees in the LOI signals to the seller that the buyer understands the human capital dimension of the transaction.

Licensing Transition Timeline and Contingency Cure Period

If the buyer cannot satisfy state licensing board requirements for firm ownership within the agreed contingency period, both parties need a defined process for either extending the deadline or unwinding the transaction without penalty. The LOI should specify the cure period, who bears costs if the contingency fails, and whether the parties will negotiate alternative structures — such as a management services arrangement — to bridge the gap while licensing issues are resolved.

Common LOI Mistakes

  • Failing to address professional licensing board requirements in the LOI — treating ownership transfer as a straightforward business transaction when it is a regulated professional services transition can derail a deal weeks before closing when the state board rejects the proposed firm structure.
  • Using total backlog as the enterprise value anchor without independently verifying contract status — sellers routinely include awarded-but-unsigned projects, verbal commitments, and renewal assumptions in backlog schedules that experienced buyers will discount by 20–40% during QoE review, creating a wide valuation gap that should be resolved at LOI stage, not during due diligence.
  • Neglecting to define the founding principal's transition role and compensation in the LOI — waiting until the purchase agreement to negotiate post-close transition terms creates leverage imbalance and frequently blows up deals when the seller realizes their expected consulting income was not factored into the purchase price.
  • Structuring an earnout tied to total firm revenue rather than retained client revenue — in a business where the founding engineer personally owns key client relationships, tying earnout payments to revenue the seller cannot directly influence incentivizes conflict and creates perverse outcomes when the buyer's new business development offsets client losses.
  • Overlooking E&O tail coverage cost and assignment in the LOI — discovering at closing that tail coverage will cost $150,000 and neither party budgeted for it is a common deal-killer in engineering and surveying transactions; this obligation must be explicitly allocated in the LOI to avoid last-minute renegotiation or deal collapse.

Frequently Asked Questions

Do I need a licensed engineer or surveyor to buy an engineering and surveying firm?

It depends on your state. Many states require that a professional engineering or surveying firm be majority-owned by a licensed PE or PLS, or that the firm maintain a licensed responsible-in-charge principal who holds an active state license. Some states permit non-licensed ownership as long as a licensed principal is designated for all technical deliverables. Before signing an LOI, buyers should engage a licensed attorney familiar with their target state's professional licensing board rules to confirm the permissible ownership structure. This analysis should be completed before exclusivity is granted to avoid wasting time and money on a deal that cannot close as structured.

How is backlog treated in an engineering firm acquisition and LOI?

Backlog — the value of contracted but unbilled work — is a critical component of engineering firm valuation and is typically addressed directly in the LOI. Buyers want backlog above a minimum threshold as a condition of closing, and earnout provisions are often tied to backlog conversion rates over 18–24 months post-close. The LOI should specify how backlog is defined (executed contracts only vs. awarded projects vs. pipeline), how it will be independently verified during due diligence, and what purchase price adjustment applies if backlog falls below the agreed threshold at closing. A backlog schedule itemized by client, contract type, and projected billing timeline should be provided by the seller before or simultaneously with LOI execution.

What earnout structures are most common in engineering and surveying firm acquisitions?

The most common earnout structures in engineering and surveying acquisitions tie payments to two metrics: revenue retention and backlog conversion. Revenue retention earnouts pay the seller a percentage of consideration if the firm retains a defined percentage — typically 75–85% — of trailing twelve-month revenue from existing clients during the 12–24 months post-closing. Backlog conversion earnouts pay out as contracted projects are billed and collected over 18–36 months. SBA-financed deals often use a seller note in lieu of a traditional earnout to satisfy lender standby requirements, so buyers should confirm earnout compliance with their SBA lender before proposing this structure in the LOI.

What happens to municipal on-call contracts and government pre-qualifications when an engineering firm is sold?

Government on-call contracts and DOT pre-qualifications are frequently non-assignable without agency consent and may require the prime firm to maintain specific licensure, bonding, or ownership characteristics. In an asset purchase, these contracts may need to be re-awarded or reassigned through a formal government process that can take months and is not guaranteed. In a stock purchase, the contracts may transfer with the entity, but a change-of-control provision can still trigger agency notification and consent requirements. The LOI should identify all government contracts that may be affected, assign responsibility for obtaining consents, and define the minimum dollar value of contracts that must be successfully assigned before the buyer is obligated to close.

How long does it typically take to close an engineering or surveying firm acquisition?

Most lower middle market engineering and surveying firm acquisitions take 4–8 months from signed LOI to closing, with SBA-financed deals typically at the longer end of that range due to lender underwriting timelines. The due diligence period alone — including QoE review, E&O history verification, license transfer analysis, and client contract review — typically takes 45–75 days. Licensing board filings, government contract assignment consents, and SBA credit approval add additional time. Buyers should build a realistic timeline into the LOI exclusivity period and request a 90-day exclusivity window with extension provisions for SBA-financed transactions rather than committing to a 60-day close that is nearly impossible to achieve.

Should the LOI be an asset purchase or stock purchase for an engineering firm?

Both structures are used in engineering firm acquisitions, and the right choice depends on the specific contract and licensing situation. Asset purchases allow buyers to select which assets and liabilities to assume, which is valuable when the seller has E&O exposure or unknown legacy liabilities. However, asset purchases complicate the transfer of government contracts, state DOT pre-qualifications, and certain professional liability insurance policies that are specific to the legal entity. Stock purchases preserve the entity and its authorizations but expose the buyer to all historical liabilities. In practice, many deals are structured as asset purchases with targeted carve-outs for specific contracts that require entity continuity, and the LOI should acknowledge that the final structure may be refined based on what due diligence reveals about contract assignability.
