Earnouts, Seller Notes, and Rollover Equity: How MSP Deals Actually Get Paid

Last updated: October 7, 2026

A buyer offers $6 million for your MSP. You tell your spouse. Maybe your accountant. Then the letter of intent shows up, and the $6 million turns out to be $4.2 million at closing, $600,000 held in escrow for 18 months, a $700,000 earnout tied to revenue retention, and a $500,000 note paid over four years.

Same price. Very different deal.

Nothing in that structure is exotic. Each piece exists for a reason, and each one moves risk from the buyer onto you. Sellers who understand the mechanics negotiate the pieces. The rest negotiate only the headline and find out on closing day what they actually agreed to.

How Does an MSP Acquisition Actually Get Paid?

An MSP acquisition’s deal structure is the mix of payments that make up the purchase price. It’s typically cash at closing, a portion held back in escrow, an adjustment for working capital, and deferred payments through an earnout, a seller note, or rollover equity in the buyer, each with different timing, conditions, and risk.

Read the table from top to bottom and the certainty drops at every row. Cash is cash. Rollover equity is a bet on someone else’s exit.

What Reaches Your Account at Closing?

Less than the cash-at-closing line in the LOI. Out of that number come any business debt, your transaction fees, the escrow, and an estimate of the working capital adjustment. Taxes come later. They’re yours.

Whether you sell stock or assets changes the math too. In an asset sale the buyer picks what it takes, and the way the price gets allocated across equipment, contracts, and goodwill can raise your tax bill in ways a stock sale wouldn’t. In a stock sale the whole company moves, liabilities included. Buyers of small companies tend to prefer assets. Bigger deals look different. In the ABA’s 2025 private target deal points study, only about a fifth of the sampled deals, 21%, were asset purchases, and every deal in that sample was priced at $25 million or more.

Ask your CPA for a closing waterfall before you sign the LOI. One page. Headline price at the top, every deduction on its own line, estimated after-tax cash at the bottom. It’s the one page every seller should ask for. Few do.

How Do Escrow and the Working Capital Peg Work?

Escrow is part of the price parked with a third party to cover claims if your representations turn out wrong. The working capital peg is a target level of short-term assets, and the price moves up or down depending on where the business actually lands at closing compared with that target.

Both are standard. In SRS Acquiom’s 2026 deal terms study, the median indemnity escrow held back roughly a tenth of deal value, and purchase price adjustments showed up in well over 90% of transactions.

Sellers lose money quietly on the peg. SRS Acquiom’s separate working capital study of more than 1,570 deals found that 51% of final adjustments landed in the buyer’s favor and 38% in the seller’s. Not a coin flip.

MSPs have it worse. Clients prepay annual agreements, block hours, and project deposits. That cash sits in your bank account, but the work hasn’t been done, so a buyer will treat it as deferred revenue, a liability the buyer inherits along with the obligation to deliver. If the peg ignores it, you’ll pay for it twice, once in the work the buyer has to perform and again in the adjustment. Define deferred revenue, receivables aging, and unbilled project work in the LOI, and set the peg from a trailing 12-month average rather than a single month that happens to suit the buyer.

Do MSP Earnouts Actually Get Paid?

Sometimes, and rarely in full. SRS Acquiom found that just over half of private-target deals with earnouts pay out anything at all, and that counting the zeros, earnouts pay about 21 cents on the dollar.

Even the successful ones stop short. SRS Acquiom’s 2025 earnout update put the payout at roughly 50 cents on the dollar when an earnout pays something, and it noted that deals with an upfront value of $50 million or less generally see lower achievement. That’s where nearly every MSP deal sits.

They’re not rare, either. Earnouts appeared in 24% of 2025 deals in the SRS 2026 study, up from 22% the year before, and the median earnout was worth 34% of the closing payment. The ABA’s larger-deal sample showed earnouts falling from 26% to 18%. So a third of your price sitting in an earnout is ordinary. Collecting it is not.

How MSP earnouts get measured

In MSP deals, earnouts tend to track revenue retention, typically recurring revenue from the clients you had at closing, measured at the end of year one and year two. Some track EBITDA instead. Avoid that if you can, because after closing the buyer controls pricing, staffing, tools, and overhead allocation, and every one of those decisions lands in your EBITDA.

Retention has traps too. What happens if the buyer moves your clients onto its PSA and changes their invoices? Or folds them into a sister brand? Or raises prices 20% and three clients leave? Without clear language, each of those can count against you.

MSPAlliance’s Charles Weaver once advised sellers to never take an earnout or performance payment that runs beyond 12 months. Firm rule. I’d treat it as a strong starting position rather than a law, since a 24-month earnout with tight definitions can beat a 12-month one with loose ones.

What to put in the earnout language

• A client list frozen at closing, with each client’s recurring revenue attached
• Gross retention of those clients as the metric. Not EBITDA.
• Buyer-caused losses excluded, including price increases, tool migrations, and service changes the buyer imposed
• Credit for clients moved to another brand the buyer owns
• Monthly reporting to you, in writing
• Acceleration if the buyer sells the business or lets you go without cause
• An independent accountant to settle disputes, named in advance

What Happens With a Seller Note?

You become the buyer’s lender. A seller note is part of the price paid later in installments with interest, and it’s only as good as the buyer’s ability and willingness to keep paying.

Notes are safer than earnouts in one way that matters. The money is owed whether or not the business hits a target. But a note is usually subordinated to the bank, which means if the buyer runs into trouble, the bank gets paid first and you wait.

SBA buyers add rules. Under the SBA’s lending procedures, a seller note can count toward the buyer’s required 10% equity injection only if it sits on full standby, with no payments, for the life of the loan, and then only for up to half of that injection. The SBA revised those procedures again on October 1, 2026, so confirm the current terms with the buyer’s lender. Picture $200,000 of your price earning nothing until the bank loan is paid off. That’s the deal.

Protect it like a lender. Get a personal guarantee from the buyer’s principals where you can, and take a security interest in the business assets so you’re not standing in line behind every other creditor if the business fails. Add cross-default language, so a missed bank payment counts as a missed payment to you, plus acceleration if the buyer sells. And get the right to see the financials every quarter, because by the time a payment is missed it’s late in the game to start asking questions.

What Is Rollover Equity?

Rollover equity is the part of your price you take as ownership in the buyer instead of cash. You sell your MSP, then reinvest a slice of the proceeds into the buyer’s company, betting that the combined business will sell later for more.

Private equity buyers love it. It keeps you invested in the outcome, and it reduces the cash they need at closing. And PE money is everywhere in this market right now. Per Omdia’s count, 80% of MSP and MSSP deals in Q1 2026 involved outside investors, compared with 68% a year before. I haven’t found a reliable public number for how frequently rollover shows up in those deals, so treat any figure you hear in a sales pitch with suspicion.

That second bite can be real. It can also be small. Or late. Or it never comes, if the platform can’t find its own buyer.

Before you roll, find out what you’re actually holding. Common or preferred units? Who sits ahead of you in the payout order when the platform sells? How was your rollover valued, and at what multiple compared with your sale? Is there a management fee coming off the top every year? Can you be dragged into a sale you don’t like, or forced to sell your units back if you leave? Our overview of how PE-backed MSP acquisitions work covers what those buyers are after, which tells you a lot about how your stake will be treated.

One SBA wrinkle catches sellers off guard. If the buyer uses an SBA loan and you keep any stake at all, even 1%, the SBA rules in effect since June 2025 require you to personally guarantee the loan for at least two years.

How Is Each Piece Taxed?

Differently, and the structure decides. Earnouts can be taxed as capital gains or ordinary income, seller notes are generally reported as installment sales, and rollover can sometimes defer tax on the rolled portion. Get a CPA involved before the LOI, not after.

Earnouts are the slippery one. Venable’s tax team explains that earnout payments are taxed as either ordinary income or capital gains depending on how the deal is structured. Tie the earnout to you staying employed, with an employment term that matches the earnout period, and it starts to look like pay. Keep your post-closing salary close to market and make the earnout payable even if you’re let go, and it looks more like purchase price.

For a seller note, IRS Publication 537 treats a sale where at least one payment arrives after the tax year of the sale as an installment sale, reported on Form 6252. Watch two details. Depreciation recapture is taxed in the year of sale even if you haven’t been paid yet. And the note needs adequate stated interest, measured against the applicable federal rate, or the IRS will recharacterize part of your principal as interest.

This isn’t tax advice. It’s the reason the tax advisor should be in the room before the structure is set.

What a Seller Should Negotiate

Run every offer through an expected value test before you compare headlines. Take two offers for the same MSP, before taxes and fees. Assume the escrow and the note are paid in full, and apply the SRS average earnout payout of about 21 cents on the dollar.

Offer B wins. And it puts $800,000 more in your account on day one, with no four-year wait on a note. Your own earnout odds might be better than the average, of course. They might also be worse.

Once you’ve picked the offer worth pursuing, push on these points.

• More cash at closing. Even a few points matter more than the same amount added to the earnout.
• Escrow size and length. Ask for a step-down halfway through the claims period.
• A working capital peg set from a trailing 12-month average, with deferred revenue defined in writing
• Earnout definitions frozen at closing, as listed above
• Security and guarantees behind any seller note
• For rollover, the payout order, the valuation, and what happens to your units if you leave

How much of this you win depends on your position at the table. That’s where early preparation pays, and where the exit strategy mistakes that cost MSP sellers money start. Clean books and three interested buyers? You can insist on cash, and a buyer who wants the business badly enough will usually find a way to give it to you. One buyer and a deadline? You can’t. If you’re still choosing who should run your sale, our comparison of brokers and sell-side advisors for MSPs is a useful place to start.

One honest caveat. If a well-funded buyer is offering 90% cash at closing with a modest escrow, you may not need much help with structure at all. Take the deal. The harder conversations come with earnouts, notes, and rollover, which is exactly where sellers sign things they don’t fully understand.
