A field-ready letter of intent framework built for marketing agency acquisitions — covering retainer revenue protections, earnout structures, key person retention, and client concentration risk in the $1M–$5M revenue range.
An LOI for a marketing agency acquisition is more nuanced than a standard business purchase offer. Unlike asset-heavy businesses, a marketing agency's value lives in client relationships, recurring retainer contracts, and the people who manage them. A well-crafted LOI must address the quality and durability of that revenue — not just the headline purchase price. For buyers, the LOI is your opportunity to lock in deal exclusivity while signaling serious intent, establish the framework for earnout mechanics tied to client retention, and surface key due diligence rights before committing to a full purchase agreement. For sellers, the LOI sets expectations on valuation approach, transition timeline, your role post-close, and how earnout milestones will be calculated and paid. In the lower middle market — where marketing agency deals typically range from $1M to $5M in revenue and 3x to 6x EBITDA — the LOI is the most consequential document in the process. Getting it right protects both sides and dramatically reduces the risk of a deal collapsing during due diligence or after close when client attrition erodes assumed value.
Find Marketing Agency Businesses to AcquireParties and Transaction Overview
Identifies the buyer entity, seller entity, and the specific assets or equity interests being acquired. For marketing agencies, this section should clarify whether the transaction is structured as an asset purchase or stock purchase, as this has material implications for client contract assignments and employee agreements.
Example Language
This Letter of Intent is entered into between [Buyer Name or Entity] ('Buyer') and [Seller Name or Entity] ('Seller'), the owner of [Agency Name], a [state] [LLC/S-Corp/C-Corp] ('the Company'). Buyer proposes to acquire substantially all of the assets of the Company — including client contracts, retainer agreements, intellectual property, proprietary processes, brand assets, and goodwill — on the terms set forth herein. The transaction is intended to be structured as an asset purchase for tax purposes, subject to final negotiation of the definitive agreement.
💡 Sellers of marketing agencies often prefer a stock sale to preserve capital gains treatment and avoid triggering assignment clauses in client contracts. Buyers typically prefer asset purchases to limit liability and cherry-pick contracts. Discuss this tension early — many agency LOIs default to asset purchase language but include a carve-out allowing the parties to revisit structure if tax counsel identifies mutual benefit in a stock transaction. Ensure the LOI specifies exactly which client contracts, retainer agreements, and IP are included in the acquired assets.
Purchase Price and Valuation Basis
States the proposed total enterprise value, the calculation methodology (typically a multiple of trailing twelve-month or normalized EBITDA), and how the price is allocated between upfront cash, seller note, and earnout. For marketing agencies, the EBITDA should be clearly defined — including adjustments for owner compensation, personal expenses, and non-recurring items — to avoid disputes during due diligence.
Example Language
Buyer proposes a total purchase price of $[X], representing approximately [X]x the Company's trailing twelve-month adjusted EBITDA of $[X], as preliminarily calculated based on Seller's representations. The purchase price shall be payable as follows: (i) $[X] in cash at closing, funded in part through an SBA 7(a) loan; (ii) a seller note of $[X] payable over [5–7] years at [6–7]% interest; and (iii) an earnout of up to $[X] payable over [12–24] months contingent on post-close revenue and client retention metrics as further described herein. The adjusted EBITDA calculation shall add back Seller's above-market compensation in excess of $[X], personal vehicle expenses, and any non-recurring costs identified during due diligence.
💡 Marketing agency valuations hinge on revenue quality. Buyers should insist the LOI defines EBITDA with specificity — particularly around how subcontractor costs, media pass-throughs, and freelancer spend are treated. A gross margin analysis by client and service line should be completed before price is finalized. Sellers should push back on any EBITDA adjustments that reduce the base without clear justification. Both parties benefit from agreeing on the EBITDA definition in the LOI to prevent disputes from derailing due diligence later.
Earnout Structure and Client Retention Mechanics
Defines the earnout payment schedule, the performance metrics that trigger payment, and how client attrition will be measured and applied. This is often the most contested section in a marketing agency LOI because it directly addresses the risk that key clients leave after ownership changes hands.
Example Language
Up to $[X] of the purchase price shall be payable as an earnout over [12–24] months following the closing date, subject to the following conditions: (i) if recurring monthly retainer revenue from clients existing at close ('Baseline Retainer Revenue') equals or exceeds [90%] of the pre-close baseline of $[X] per month during the earnout period, Buyer shall pay Seller the full earnout amount; (ii) for each percentage point by which Baseline Retainer Revenue falls below [90%], the earnout shall be reduced pro rata; (iii) any new retainer revenue generated post-close from new clients shall not be credited toward Baseline Retainer Revenue for earnout calculation purposes. Earnout payments shall be made quarterly with supporting revenue reports delivered to Seller within 15 days of each quarter-end.
💡 Earnout disputes are the single most common source of post-close litigation in marketing agency acquisitions. Sellers should insist on: (1) a clear definition of what constitutes 'retainer revenue' versus project revenue; (2) audit rights to verify earnout calculations; (3) protections preventing the buyer from artificially suppressing earnout payments by restructuring client billing. Buyers should resist crediting new client revenue against lost client attrition — earnouts should measure what the seller actually delivered, not what the buyer built post-close. Consider a neutral accountant provision for disputed earnout calculations.
Due Diligence Period and Access Rights
Establishes the length of the due diligence period, the scope of information to be provided by the seller, and the confidentiality obligations governing all shared materials. For marketing agencies, due diligence must cover client contracts, retainer renewal rates, employee agreements, and key person dependencies.
Example Language
Buyer shall have [45–60] calendar days from the execution of this LOI to complete its due diligence review ('Due Diligence Period'). During this period, Seller agrees to provide Buyer with reasonable access to: (i) three years of financial statements and monthly revenue reports segmented by client and service line; (ii) all client contracts, retainer agreements, and statements of work, including renewal terms and cancellation clauses; (iii) employee compensation schedules, non-solicitation agreements, and organizational charts identifying key account managers; (iv) documentation of all proprietary processes, SOPs, and technology systems; and (v) any material correspondence relating to client satisfaction, disputes, or threatened cancellations. All information shared shall be governed by the Mutual Non-Disclosure Agreement previously executed by the parties.
💡 Buyers should request a client-by-client revenue summary in the LOI — broken down by retainer vs. project revenue, contract expiration dates, and renewal history. This is the single most important due diligence deliverable for a marketing agency. Sellers should be cautious about sharing client identities and pricing before exclusivity is confirmed and a robust NDA is in place. If the seller has not yet converted project clients to retainers, due diligence is a good opportunity to demonstrate that pipeline before close.
Exclusivity and No-Shop Provision
Grants the buyer an exclusive negotiating period during which the seller agrees not to solicit, entertain, or accept competing offers. This protects the buyer's investment of time and capital during due diligence.
Example Language
In consideration of the time and expense to be incurred by Buyer in conducting due diligence, Seller agrees that for a period of [45–60] days following execution of this LOI ('Exclusivity Period'), Seller shall not, directly or indirectly, solicit, encourage, or enter into discussions with any third party regarding the sale, merger, recapitalization, or other disposition of the Company or its assets. Seller shall promptly notify Buyer if any unsolicited inquiry is received during the Exclusivity Period. The Exclusivity Period may be extended by mutual written agreement if due diligence is ongoing and the parties are making material progress toward a definitive agreement.
💡 Sellers should resist exclusivity periods longer than 45–60 days unless the buyer has demonstrated clear financing capability and deal momentum. Buyers should not sign an LOI without exclusivity — sharing financials, client rosters, and employee information without exclusivity creates significant competitive exposure. Consider including a provision that exclusivity automatically terminates if the buyer fails to provide a due diligence request list within 10 business days of LOI execution, ensuring the buyer stays on pace.
Key Person and Seller Transition Obligations
Defines the seller's required involvement post-close, including a transition consulting period, non-compete and non-solicitation obligations, and any conditions tied to the seller's continued presence for client relationship stability.
Example Language
Seller agrees to remain available as a transition consultant for a period of [12–24] months following the closing date at a mutually agreed monthly consulting fee of $[X], with duties including client introductions, account transition support, and staff mentorship. As a condition of closing, Seller shall execute a non-competition agreement prohibiting Seller from directly or indirectly engaging in the marketing agency business within [geographic area or niche vertical] for a period of [3–5] years following the closing date. Seller shall also execute a non-solicitation agreement prohibiting Seller from soliciting the Company's clients, employees, or contractors for a period of [3–5] years post-close. The consulting arrangement may be terminated by either party with [30] days' notice after the initial [6]-month period.
💡 For marketing agencies, the seller's transition role is critical to client retention — especially when the founder has deep personal relationships with top accounts. Buyers should structure the consulting arrangement to incentivize proactive introductions, not passive availability. Sellers should negotiate the consulting fee as a separate line item from the purchase price — it is compensation for services, not part of the deal economics. Non-compete scope should be limited to the agency's actual service lines and verticals, not a blanket prohibition on all marketing work.
Closing Conditions and Financing Contingency
Identifies the conditions that must be satisfied before the transaction can close, including financing approval, consent of key clients, and completion of satisfactory due diligence. For SBA-financed acquisitions, the financing contingency is a critical protective clause for the buyer.
Example Language
The closing of this transaction shall be conditioned upon: (i) Buyer's receipt of SBA 7(a) loan approval in an amount sufficient to fund the cash portion of the purchase price; (ii) completion of due diligence to Buyer's reasonable satisfaction, with no material adverse findings relating to client churn, undisclosed liabilities, or employee departures; (iii) execution of assignment consents from clients representing no less than [80%] of trailing twelve-month retainer revenue, where such consent is required by the applicable client agreement; (iv) execution of employment or retention agreements with key account management personnel identified by Buyer; and (v) delivery of audited or reviewed financial statements for the three most recent fiscal years. Either party may terminate this LOI if closing conditions are not satisfied or waived within [90] days of execution.
💡 The client consent condition is particularly sensitive for marketing agencies — some retainer agreements contain change-of-control or anti-assignment clauses that require client approval before the contract can transfer to a new owner. Buyers should identify which clients have such clauses early in due diligence. Sellers should negotiate a materiality threshold — requiring consent only from clients representing 80–85% of retainer revenue protects against a single small client derailing a deal. SBA financing contingencies are standard and sellers should expect them in any buyer using leverage.
Confidentiality and Non-Binding Nature
Clarifies which sections of the LOI are legally binding and which are expressions of intent only. Standard LOIs are largely non-binding except for exclusivity, confidentiality, and expense provisions.
Example Language
This Letter of Intent is intended to summarize the principal terms of a proposed transaction and is not intended to create a legally binding obligation on either party to consummate the transaction, except as follows: the provisions of this Section [X] (Confidentiality), Section [X] (Exclusivity), and Section [X] (Expenses) shall be legally binding and enforceable. All other terms herein are subject to the negotiation and execution of a definitive Purchase Agreement and related transaction documents. Neither party shall be obligated to proceed with the transaction unless and until a definitive agreement is fully executed by both parties.
💡 Both buyers and sellers sometimes assume the LOI commits them to the deal — it generally does not, except for the binding provisions. Sellers should understand that a buyer can walk away after due diligence without liability unless specific binding commitments were made. Buyers should ensure the confidentiality provision explicitly covers client identities, pricing, and employee compensation data shared during due diligence — this information is highly sensitive in the agency business and must be protected even if the deal does not close.
Earnout Revenue Definition: Retainer vs. Project Revenue
The most consequential negotiating point in any marketing agency LOI is precisely how earnout revenue is defined and measured. Buyers want to tie earnout payments to recurring retainer revenue only — excluding one-off project work that may not repeat. Sellers want credit for total agency revenue, arguing that project clients often convert to retainers over time. The parties should agree in the LOI on a specific definition: does 'retainer revenue' include month-to-month agreements without long-term contracts? How are media pass-through billings treated? What happens if a client reduces its retainer spend by 30% but does not cancel? Ambiguity here is the root cause of most earnout disputes. Define it precisely — with dollar thresholds, measurement periods, and escalation mechanics — before moving to a definitive agreement.
Client Concentration Risk and Price Adjustment Triggers
If a single client represents more than 20–25% of the agency's revenue, that concentration is a material deal risk that should be reflected in both price and structure. Buyers should negotiate a purchase price adjustment mechanism tied to the departure of any client representing more than a defined threshold of revenue — for example, if the top client representing 30% of revenue departs within 12 months of close, the purchase price is reduced by a formula tied to lost EBITDA. Sellers should push back on overly aggressive reduction formulas and argue for a floor below which further adjustments do not apply. Both parties benefit from agreeing on concentration thresholds in the LOI rather than discovering the issue during due diligence.
Key Employee Retention Requirements as a Closing Condition
Marketing agencies often have one or two account managers, creative directors, or digital strategists whose departure would materially harm client relationships and post-close revenue. Buyers should make the execution of retention agreements with identified key employees a closing condition — not just a best-efforts obligation. Sellers should ensure they can deliver on this commitment by having candid conversations with key staff before exclusivity is signed. The LOI should identify which roles — not necessarily names — are considered material, so that if a specific individual departs pre-close, the parties can assess whether a suitable replacement satisfies the condition.
Seller Note Terms and Subordination to SBA Financing
In SBA 7(a) financed acquisitions, the SBA lender will require any seller note to be subordinated to the bank's senior debt position for the duration of the loan. This means the seller cannot receive principal payments on the note during the standstill period — typically the first 24 months post-close. Sellers should understand this restriction before agreeing to seller note terms in the LOI. Buyers should accurately represent SBA standstill requirements to sellers upfront rather than disclosing them late in the process. The LOI should reference SBA compliance as a structural constraint so that both parties enter due diligence with aligned expectations on seller note liquidity.
Non-Compete Scope, Geography, and Duration
Non-compete agreements for marketing agency founders must be carefully scoped to be enforceable and fair. A blanket prohibition on all marketing work for five years is likely unenforceable and will create friction. Instead, the non-compete should be limited to: (1) the agency's specific service lines and verticals — for example, healthcare SEO or e-commerce PPC management; (2) a defined geographic market or client base; and (3) a reasonable duration of three to five years from close. Sellers who plan to remain active in the marketing industry in a different capacity — such as consulting, teaching, or working in a non-competing vertical — should negotiate carve-outs explicitly in the LOI rather than trying to add them to the definitive agreement after the non-compete framework is set.

Most sections of a marketing agency LOI are intentionally non-binding — the purchase price, structure, earnout terms, and closing conditions are all expressions of intent subject to a final definitive agreement. However, three sections are typically made legally binding: the exclusivity or no-shop provision, the confidentiality obligations covering client data and financial information shared during due diligence, and the expense allocation clause. Because marketing agencies involve highly sensitive information — client rosters, pricing, employee compensation — buyers and sellers should ensure the confidentiality provision is robust and enforceable before sharing any data room materials.
Earnouts in marketing agency acquisitions are most effective when tied to recurring retainer revenue retention rather than total revenue, since project work is inherently unpredictable. A well-structured LOI earnout clause should define: (1) the baseline retainer revenue figure against which post-close performance is measured; (2) the retention threshold that triggers full earnout payment — typically 85–90% of baseline; (3) the pro-rata reduction formula for revenue below that threshold; (4) the measurement period — usually 12–24 months post-close with quarterly payment intervals; and (5) audit rights for the seller to verify the buyer's revenue calculations. Avoid earnout structures that give the buyer broad discretion over how revenue is categorized or billed post-close.
Marketing agencies in the $1M–$5M revenue range typically trade at 3x to 6x adjusted EBITDA. Where a specific agency falls within that range depends heavily on revenue quality. An agency with 70%+ recurring retainer revenue, a diversified client base with no single client exceeding 20% of revenue, documented SOPs, and a tenured account management team commands the higher end of the range. An agency with predominantly project-based revenue, high owner dependency, or a client concentration risk will trade closer to 3x. SBA lenders are active in this market and comfortable underwriting deals in the $1M–$3M enterprise value range, which keeps the buyer pool competitive and supports valuations.
The five most critical due diligence areas for a marketing agency are: (1) client contract review — specifically retainer terms, cancellation clauses, change-of-control provisions, and renewal history; (2) revenue quality analysis — the split between recurring retainer and one-off project revenue, client tenure, and historical churn rates; (3) key person dependency — mapping which client relationships are held by the founder versus account managers, and whether key staff have non-solicitation agreements; (4) gross margin by client and service line — including how subcontractor, freelancer, and media pass-through costs are allocated; and (5) employee agreements — confirming that non-solicitation and confidentiality provisions are in place for all staff with client-facing roles. These five areas should be explicitly referenced in the due diligence access provisions of the LOI.
Most marketing agency acquisitions require a 12–24 month seller transition period, longer than many other business types, because client relationships in agencies are often deeply personal and tied to the founder's credibility and trust. A 90-day hard cutoff is rarely sufficient when retainer clients have worked with the founder for years. The LOI should specify a formal consulting arrangement — typically 12 months at a defined monthly fee — with an option to extend. During this period, the seller should be actively introducing the buyer or new account leads to key clients, not simply making themselves available on request. Buyers should structure the consulting fee separately from the purchase price and earnout, and avoid making it contingent on earnout performance to prevent conflicts of interest.
Yes, marketing agencies are generally eligible for SBA 7(a) financing when the business meets SBA size standards and the buyer meets creditworthiness requirements. SBA lenders are active in this space, particularly for acquisitions in the $500K–$3M enterprise value range. A typical SBA-financed marketing agency deal involves 10–20% buyer equity injection, an SBA 7(a) loan covering 60–70% of the purchase price, and a seller note covering the gap — though SBA rules require the seller note to be on full standby for at least 24 months post-close. Lenders will scrutinize the quality of recurring retainer revenue, client concentration, and cash flow consistency. Agencies with documented retainer contracts and three years of clean financials are most lender-friendly.
