How to sell a marketing agency

General information, not legal, tax or financing advice. Contract, employment, copyright and tax rules differ by state and by deal, so confirm how they apply to your sale with your attorney, your CPA and the buyer's lender.

1. Decide when to sell and what you want from it

FE International recommends 12 to 24 months of preparation, because buyers price trailing-twelve-month performance and a change made today takes about a year to show. TobinLeff, an M&A advisor to marketing agencies and PR firms, calls three to five years realistic, since most agency valuations weight three to five years of adjusted EBITDA.

Then decide what you want from the sale. Marketing agency buyers differ on four points:

• Cash at closing. In 21 agency deals reported by TobinLeff, 15 included earnouts (averaging about 28% of the total purchase price) and 12 included rollover equity (about 21% of the average purchase price). Step 7 covers these terms.
• How long you stay. Agency consultant Karl Sakas says most agency exits keep the owner involved for six months to several years, and that this is negotiable.
• Your team. Sakas says financially motivated buyers usually will not commit to keeping the whole team, though they may keep certain executives for 6 to 12 months. TobinLeff says strategic acquirers, such as larger agencies and holding companies, typically want to keep key employees and often write retention provisions into the deal.
• Who carries it on. The Agency Management Institute, an advisor to small agencies, says many owners' ideal exit is an internal sale to a successor they have been grooming (step 6).

Then put a number on it: start with the published ranges on what a marketing agency is worth, or estimate a range from your own numbers.

2. Get the books ready: accrual, AGI and add-backs

Advisors generally value a marketing agency on a multiple of trailing-12-month adjusted EBITDA, Axial reports, drawing on two agency advisors. FE International says SDE (seller's discretionary earnings) pricing fits founder-run agencies, typically under $2 million of revenue or $500,000 of EBITDA. Either way, TobinLeff says a third-party Quality of Earnings (QoE) review of your tax returns, bank statements and general ledger, not the headline EBITDA, decides what the buyer pays and how certain the close is.

• Move to accrual accounting. FE advises accrual books and monthly P&Ls that reconcile. It names cash-basis books that will not reconcile, and revenue recognized before the work is delivered, as predictable red flags in agency diligence. A TobinLeff CPA partner advises booking client payments received in advance as deferred revenue, a liability, not as income on receipt.
• Separate pass-through costs from fee revenue, so buyers see the true earnings base (FE). Agency finance consultancy Parakeeto says pass-through left in revenue can inflate an agency's sense of its revenue and throw off its profit measures, especially with heavy media buying, print or outsourced production. Its measure is agency gross income (AGI): gross revenue minus pass-through expenses. If your P&L books media gross, show AGI beside it.
• Document every add-back. TobinLeff says undocumented add-backs are discounted or rejected, and advises reviewing three years of monthly margin data, because unexplained spikes or dips surface in diligence. FE suggests recasting the financials into an adjusted EBITDA bridge.
• Gather the documents early. FE's standard agency diligence list: three years of P&Ls and balance sheets, tax returns, client contracts and amendments, revenue by client by month, employment and contractor agreements, IP assignments, insurance policies and your SOP library. TobinLeff warns that diligence after the letter of intent can be like a new half-time job for you and your key staff.

If the buyer uses an SBA 7(a) loan, the lender (under SBA SOP 50 10 8.1, effective October 1, 2026) analyzes your three most recent year-ends and checks the figures the business valuation relied on against your IRS transcripts. Make sure every add-back reconciles to your filed returns.

3. Check how each client contract transfers

How your client contracts move depends on the deal structure. Vancouver law firm Clark Wilson, writing on general contract principles, describes two cases:

• Asset sale. Your contracts move to the buyer by assignment, which triggers any assignment clause and the need to get the client's consent.
• Stock sale. The company keeps its contracts, so no assignment is needed, and consent is required only if a contract specifically prohibits a change of control.

In the U.S. the answer turns on each contract's wording and governing law, so have your attorney read every material client agreement. The structure changes your tax too: selling corporate stock usually produces capital gain or loss, per the IRS (step 9). Settle it with your attorney and CPA before the letter of intent.

FE names contracts that terminate on a change of control as a predictable red flag, and advises renewing client contracts and confirming they are assignable before a sale. Asking for consent tells the client about the sale, which Clark Wilson says raises confidentiality issues. FE calls a leak to clients or staff mid-process the most common self-inflicted wound in agency sales, in its experience, and advises telling clients at or just after closing through a plan agreed with the buyer. Clients whose contracts need consent will hear sooner, so plan those conversations with the buyer too.

Then read what each contract commits the client to. Omnicom says substantially all of its client contracts let either side cancel on short notice, typically 90 days. Small-agency retainers vary, and a buyer will read yours for notice periods. TobinLeff calls client concentration a frequent diligence red flag and advises keeping any one client under 20% of revenue (other advisors draw the line elsewhere). The guide to client concentration and retainers covers what to fix first.

If you hold clients' customer data, check the data terms. Under California's CCPA, a service provider's written contract must bar it from using that data outside the client relationship. Data you hold in your own right, such as your own leads and subscribers, can transfer in an acquisition without counting as a sale if the buyer uses it consistently with the CCPA. Confirm with your attorney how this applies to your client agreements.

4. Make the agency less dependent on you, and keep the team

FE International estimates that agencies where the founder is the main rainmaker or client contact face a 15% to 30% valuation discount, an advisor estimate with no cited data. Karl Sakas, writing in December 2025 about agencies with $2 million or more in revenue, says acquirers told him an agency that cannot run two weeks without the owner is not ready to sell. They look for delegated client relationships, a contractually bound second-in-command, SOPs, and an owner who is not the only one who knows the passwords.

TobinLeff advises putting retention incentives in place before the sale, even if the bonuses come out of your own pocket. It designs such plans, and bonuses paid at closing can have tax effects, so ask your CPA. Advisors differ on when to tell staff. FE suggests one or two key leaders early under an NDA and the wider team at signing or closing. TobinLeff favors telling your leadership team as early as your relationships allow, and once you have a promising letter of intent at the latest.

Non-competes and non-solicits

The FTC's nationwide non-compete rule is not in effect: a federal court stopped it in August 2024, and a final rule published on February 12, 2026 removed it. State law decides, and these states treat the non-compete you sign as a selling owner differently from your employees' non-competes.

California's exception covers an owner who sells all of their ownership interest, or whose company sells all or substantially all of its operating assets with goodwill. If you keep a stake, ask counsel whether your covenant fits.

Non-solicits are treated separately. Minnesota's ban does not cover non-solicitation agreements or limits on using client lists. From June 30, 2027, Washington allows an employee's client non-solicit only for clients they established or substantially developed a direct relationship with, and for up to 18 months after they leave; a clause barring them from accepting a client's business is a void non-compete. FE advises having employment agreements with non-solicits in place before a sale. Confirm with your attorney which of yours will hold up in your state.

5. Make sure the agency owns its work and its accounts

Under the Copyright Act, work is “made for hire” (owned by the hiring party) only if an employee created it within the scope of their job, or if it was commissioned for one of nine listed uses under a signed agreement expressly calling it a work made for hire. If a freelancer's logo, site code or ad creative does not fit those rules, check that you hold a signed assignment: under 17 U.S.C. 204(a), a transfer of copyright ownership is valid only in a signed writing.

FE lists freelancer IP without signed assignment clauses as a predictable red flag, and advises contractor agreements that assign IP to the company. Collect missing assignments while you still work with those freelancers, and confirm with your attorney who owns what you have delivered to clients.

Ad accounts and partner badges

Map which client ad accounts sit under your manager accounts, and who created each, before a buyer asks.

• Google Ads. A manager account can own a client account, but the client still owns its data and can unlink. A manager that creates an account owns it; one that links an existing account does not by default. Google's third-party policy requires a separate account for each end-advertiser an agency manages. A client on monthly invoicing through your manager account that unlinks stops serving ads unless billing moves first.
• Meta. A business relates to an ad account as its owner or as its agency. Claiming an account is a one-time step, after which only that Business Manager can manage it, and Meta says most marketing companies request access to client accounts instead.
• Google Partner badge. It needs $10,000 of ad spend across managed accounts over 90 days and at least 50% of account strategists certified in Google Ads. Certifications belong to individuals and expire after a year; a company that stops qualifying has a 60-day grace period. Show the buyer both. The guide to selling a digital or performance agency covers Meta and HubSpot tiers.

6. Choose the kind of buyer

Individual buyers. By our count from SBA's public loan data, 331 “Change of Ownership” 7(a) loans were approved for agency-type borrowers (advertising, PR, media buying, marketing consulting, graphic design and related codes) from fiscal 2021 to June 30, 2026; 66% were under $1 million. Some acquisition loans may be coded differently. Across all industries, 78% of buyers in BizBuySell's Q2 2026 Insight Report expected to use SBA financing. Quiet Light, an online-business broker, says first-time buyers and corporate escapees, often marketing and sales professionals, look for smaller firms with clear systems, recurring retainers and documented processes.

Other agencies. Some buy client books with little cash up front. One web agency owner wrote that he bought a New Hampshire web design firm with fewer than 40 clients for $4,000 down plus an 18-month earnout. CyberOptik describes paying sellers 80% to 90% of the monthly net recurring revenue from the acquired clients, typically over 24 months, with nothing up front, so client churn comes straight out of the seller's payment.

Successor or employees. Under SBA SOP 50 10 8.1, a sole owner can sell 100% to someone who has worked at the business for at least 24 months as an Existing Owner Buyout. The lender may then reduce or waive the 10% equity injection if the business has enough liquidity and working capital, and no Quality of Earnings report is required. An employee stock ownership plan (ESOP) costs $200,000 to $500,000 to set up in most deals, per the National Center for Employee Ownership, and the named agency ESOPs (Mower, Ologie) are mid-size firms.

Private equity. Quiet Light says private equity groups and independent sponsors target scalable agencies with $1 million or more of annual profit. In Capstone Partners' Marketing Services count for 2026 through February 24, add-ons made up 85.2% of PE buyouts and new platforms fell 50% year over year, on small deal counts.

Strategic buyers. They made up 68.6% of Marketing Services deals in the same count, led by private strategic acquirers consolidating competitors. COMvergence counted 55 marcom agency acquisitions worldwide in 2025 by the acquirers it tracks, and 67% of the firms bought had fewer than 100 employees. Holding companies differ on earnouts: Stagwell's recent ones depend on continued employment and earnings targets, while Omnicom says some of its earnouts do not depend on employment.

7. Agree the deal structure

Cash at closing and earnouts

UK law firm Lewis Silkin says earnouts are popular in advertising and marketing deals because so much agency value sits with the founders and their client relationships that buyers want them to stay for a set period. In 2022 it put UK earnouts at about three years.

Earnouts can pay less than the headline. In SRS Acquiom's data, mostly larger private deals across all industries, sellers received about one in five potential earnout dollars, and lower middle-market deals (upfront payments of $50 million or less) that paid anything paid a median of 43 cents on the dollar. Molzi's founder left part of his three-year earnout on the table when he left midway through year two. He recommends tying an earnout to something the seller controls, such as sales, rather than EBITDA.

Lewis Silkin lists protections sellers negotiate: the buyer may not remove the sellers as directors or end their employment other than for cause, force costs on the business that depress its profit, or move key client accounts elsewhere in its group. The guide to earnouts and cash at close covers payout terms.

Seller notes and rollover equity

A Yale School of Management note on search-fund deals says seller notes typically run 3 to 7 years at 5% to 10% interest, usually unsecured and subordinated to senior debt, and that the equity a seller rolls over is usually 5% to 30%, sometimes with a board seat. Some holding companies buy a majority stake instead: Havas acquired majority stakes in 11 agencies in 2025.

Expect buyers to ask for a note. Across all industries, 90% of buyers in BizBuySell's Q2 2026 survey expected seller financing, while only 29% of owners planned to offer it.

Working capital

TobinLeff says most agency deals are valued cash-free, debt-free, with a working-capital “peg” set from a historical measure such as a trailing 12-month average. The gap between the peg and what you deliver at closing adjusts the price dollar for dollar, and if “sufficient working capital” is not defined before the letter of intent, the power in the deal shifts to the buyer.

Some buyers treat year-end bonus accruals, client retainers received for future work and advances on media purchases as debt, so you deliver equivalent cash. FE calls the working capital target a frequent late-stage friction point. Agree how retainers and media advances are treated before you sign.

The letter of intent

FE says the letter of intent (LOI) sets cash at close, earnout terms, exclusivity and your commitment after closing, and that 60 to 90 days of exclusivity is standard, with shorter periods favoring the seller. Price and payment terms in an LOI are usually non-binding, so they can be renegotiated after due diligence, M&A attorney Andrew Sherman writes.

That leaves room for a re-trade. Likeable Media's owners had a 100% cash offer at 6.5 times EBITDA that the acquirer changed to 60% up front after the LOI was signed, and they walked away. BizBuySell suggests limiting exclusivity, setting due diligence deadlines and defining what material change justifies renegotiation. Also ask any advisor how it is paid on earnout dollars: one M&A advisor, writing on Divestopedia in 2017, said advisors often required the full success fee at closing, even on earnout dollars paid later or never.

8. If the buyer uses an SBA 7(a) loan

SBA SOP 50 10 8.1 took effect on October 1, 2026 for 7(a) applications issued an SBA loan number on or after that date; SBA told lenders to keep using SOP 50 10 8.0 for applications submitted through September 30, 2026. A 7(a) loan can fund an asset or a stock purchase in the circumstances SBA describes, including one made up of intangibles such as goodwill and client lists, if SBA's change-of-ownership due diligence is met. Most rules below are for an Initial Acquisition, SBA's default category: a sale to a new majority or largest owner who was not already an owner, or has worked at the business for fewer than 24 months.

What these rules mean for you as the seller:

• The lender's valuation caps the debt. An accredited appraiser prepares it for the lender, which cannot use one prepared for you or the buyer; at a price of $350,000 or less the lender may value the business itself, unless buyer and seller are closely related. A price above the valuation must be made up by equity, such as the buyer's cash or a seller note on full standby.
• The QoE tests what agency buyers worry about. In an Initial Acquisition or Business Expansion priced at $3 million or more, the lender's QoE must assess customer concentration, contract continuity and whether revenue and margins will hold, and document every add-back, including owner pay. It must not be prepared by or for the seller, so a sell-side QoE does not replace it.
• Your handover has to fit 24 months. After an Initial Acquisition you generally cannot stay as an officer, director, stockholder or employee, but the business may hire you as a consultant for up to 24 months in total (12 under SOP 50 10 8.0). If you are the main client contact, plan the introductions inside that window.
• A buyer in your industry group may need less equity. If a business with at least two full fiscal years under its current ownership buys 100% of your agency in the same four-digit NAICS Industry Group, the lender may reduce or waive the 10% equity. Group 5418 covers advertising, PR, media buying and related services; marketing consulting (541613) and graphic design (541430) sit outside it, and the lender decides which code fits.
• Keeping a slice has a cost. In an SBA-financed partial sale, if you keep less than 20%, you must give a full guaranty of the whole loan for at least two years after final disbursement.

9. Tax questions to take to your CPA

General information, not tax advice. Ask these before you sign a letter of intent.

• How will the price be allocated? In an asset sale where goodwill attaches, you and the buyer generally both report it on IRS Form 8594. The price fills classes I to VI up to fair market value and the rest goes to Class VII, goodwill; Class VI includes workforce in place, customer-based intangibles and non-competes. A written allocation you agree binds you both unless the IRS finds it inappropriate. Sellers typically push for goodwill (capital gain for individual and pass-through sellers holding long term), buyers for assets they can write off faster. Receivables for work already done are not capital assets.
• How much goes to my non-compete? Price allocated to a seller's non-compete is taxed at ordinary income rates, an ABA Tax Lawyer article notes in discussing a court case. The buyer amortizes goodwill and a deal non-compete over the same 15 years under section 197, so ask why a buyer wants a large non-compete allocation. Form 8594 also asks about any non-compete, employment or similar agreement with you and the most it will pay.
• Is my earnout purchase price or pay? Law firm Gesmer Updegrove says the IRS may treat an earnout payable only if you stay employed as compensation, and that a separate employment or services agreement with a guaranteed salary can help reduce that risk. The IRS calls a sale priced partly on future profits a contingent payment sale, and a later payment that changes the allocation needs a supplemental Form 8594.
• Can I report a seller note on the installment method? If at least one payment comes after the year of sale, you may be able to report gain as payments arrive, or you can report it all in the year of sale. Depreciation recapture, including section 197 amortization and section 179 deductions, is reported in full in the year of sale even on installments. Ask when that tax falls due if your note is on SBA full standby.
• Is my agency a C corporation? The IRS says a corporation's profit is taxed when earned and again when paid out as dividends, and that a corporation generally recognizes gain or loss on a liquidating sale of its assets. S corporations avoid that double tax on corporate income but can owe entity-level tax on certain built-in gains.
• Do I have personal goodwill? In Martin Ice Cream (1998), the U.S. Tax Court held that a shareholder's personal customer relationships were his own assets, not the corporation's, because he never signed a non-compete or employment agreement with it. In Howard (Ninth Circuit, 2011), described in an archived 2015 AICPA Tax Adviser article, a dentist who had signed both with his own practice could not treat sale proceeds as personal goodwill; the IRS's treatment of the payment as a dividend was upheld. If your client relationships are personal to you, ask whether either case bears on your sale.

How long does it take to sell a marketing agency?

Without preparation, FE says due diligence alone can take six to nine months. TobinLeff's two published timelines span about six to fourteen months from preparation to close. In the IBBA survey, deals of $2 million to $5 million rose from 9 to 11.5 months. FE's handover estimate is shorter than Sakas's six months to several years (step 1), and an SBA-financed Initial Acquisition caps your consulting at 24 months (step 8).
