8 Things to Include in a Business Purchase Agreement
When you’re selling a business, the purchase agreement is where the deal stops being a “handshake understanding” and becomes a legally enforceable roadmap. It’s also where many owners unknowingly give away leverage—by leaving key terms vague, relying on boilerplate, or assuming “we’ll work it out later.” In the middle market, “later” usually shows up as a price chip at closing, a post-close dispute, or an earn-out that never pays.
A strong purchase agreement doesn’t need to be overly complex. It needs to be clear, commercially reasonable, and aligned with how buyers actually underwrite risk. That’s why we encourage sellers to treat the purchase agreement as the final translation of your negotiating leverage—not a formality after the LOI.
What a Business Purchase Agreement Really Does
A business purchase agreement (asset purchase agreement or stock purchase agreement) is the contract that transfers ownership and defines the rights, obligations, and protections for both parties. It memorializes what is being sold, what is assumed, what is excluded, and what happens if something turns out to be different than expected.
For most sellers, the purchase agreement is also where the economic “headline number” gets converted into real proceeds—after working capital adjustments, escrow/holdback terms, indemnities, and any seller financing or earn-out mechanics are applied. If you want the deal you thought you negotiated, this document is where you protect it.
1) The Core Deal Terms (Don’t Assume These Are “Standard”)
Yes, every agreement identifies the parties, the business, and the purchase price. But sophisticated buyers focus on the details under those headings:
- What’s being sold: assets vs. stock, included/excluded assets, assumed liabilities
- Purchase price structure: cash at close, seller note, earn-out, rollover equity
- Working capital target: how it’s calculated and when it’s measured
- Closing conditions: required consents, third-party approvals, financing contingencies
Real-world example: a seller agrees to a “$12M purchase price,” only to learn late in diligence that the buyer expects a working capital peg that effectively reduces proceeds by $600K. The number didn’t change—the definitions did.
Owners who want a clean path through the process often benefit from understanding the steps to selling a business so the purchase agreement doesn’t become the first time they see how buyers convert risk into terms.
2) Representations & Warranties (And the Survival Period)
Representations and warranties are the seller’s statements about the business: financials are accurate, taxes are filed, contracts are valid, there are no undisclosed liabilities, and so on. The key is not just what you represent—but how long you’re on the hook and what remedies the buyer has if something is wrong.
Two practical points sellers often miss:
- Materiality qualifiers: “no material adverse changes” is very different than “no changes.”
- Survival periods: some reps survive 12–18 months; taxes and certain “fundamental reps” can survive longer.
Example: a buyer later claims a customer contract was not properly assigned. If contract assignability was represented broadly and survives 18 months, the buyer may pursue a claim against escrow—even if the underlying issue is minor.
3) Indemnification, Escrow/Holdback, and Claim Mechanics
Indemnification is the “what happens if…” section. It’s where sellers either cap their exposure or accidentally leave the door open for ongoing liability.
Key items to negotiate and define clearly:
- Cap: the maximum amount the seller can owe (often a % of purchase price)
- Basket/deductible: the threshold before claims are payable
- Escrow/holdback: amount and duration (and what claims can be made against it)
- Process: notice requirements, dispute timelines, who decides if a claim is valid
Example: we’ve seen sellers agree to an escrow that releases in 18 months, but the claim process allows the buyer to “freeze” escrow amounts indefinitely with minimal documentation. The seller wins the argument eventually—but the money is stuck when they need it most.
4) Purchase Price Adjustments (Especially Working Capital)
Working capital adjustments are one of the most common sources of post-close conflict because they feel technical—but they’re fundamentally economic. If the agreement doesn’t define the accounting methodology, you can end up debating GAAP interpretations with a buyer who has far more resources.
What to include:
- Definition of working capital: what accounts are included/excluded
- Accounting basis: consistent with historical financial statements, not “buyer’s GAAP”
- Timeline: when the closing statement is delivered and when disputes must be raised
This is also why sellers who prepare early and validate earnings quality tend to negotiate from a stronger position. A well-supported financial story—often reinforced by a Quality of Earnings (QoE) report—reduces the buyer’s perceived risk and limits their ability to “re-trade” through adjustments and reserves.
5) Transition Services and the Seller’s Post-Close Role
Many deals require the seller to stay involved after closing—sometimes formally, sometimes informally. If the agreement doesn’t specify the scope, sellers can find themselves effectively “on call” while trying to move on.
Consider including:
- Transition period: length and expected time commitment
- Role definition: advisor vs. employee vs. contractor
- Compensation: included in purchase price or separate consulting/employment agreement
- Decision rights: who controls hiring, pricing, vendor changes during transition
Example: a founder agrees to “help for 90 days,” but the buyer’s integration takes longer. Without clarity, the seller becomes the de facto operations manager—while the buyer ties earn-out performance to changes the seller can’t control.
Owners who have already reduced key-person risk generally have more flexibility here; building a management team and distributing customer ownership can materially improve leverage in these negotiations. That dynamic shows up repeatedly when reducing owner dependency increases business valuation and deal certainty.
6) Non-Compete, Non-Solicit, and Confidentiality
Most buyers will require restrictive covenants. Sellers should expect this—but also ensure the terms are reasonable and aligned with what they actually plan to do next.
Key points to define:
- Geography: a radius, a state list, or “where the company does business” (very different outcomes)
- Duration: often 3–5 years, depending on industry and jurisdiction
- Scope: what activities are prohibited (and what is explicitly permitted)
Example: a seller wants to retire but also invest in a friend’s startup. A broadly written non-compete can unintentionally restrict passive investing or advisory roles unless carved out.
7) Treatment of Employees, Benefits, and Key Contracts
Even in an asset sale, employees and contracts often need to be transitioned thoughtfully. The purchase agreement should clarify:
- Which employees are offered employment: and when offers must be made
- Accrued PTO/benefits: who pays what at closing
- Key customer/vendor contracts: required consents and who is responsible for obtaining them
- Benefit plans: whether the seller remains covered during a defined period (if negotiated)
Scenario: a seller assumes a key customer contract will transfer automatically, but it requires written consent. If consent isn’t obtained by closing and the agreement doesn’t allocate the risk, the buyer may demand a holdback or special indemnity.
8) Payment Structure: Seller Notes, Earn-Outs, and Security
Getting paid is not just about the headline price—it’s about when, how, and how certain. If any portion is deferred, the agreement should be explicit.
For seller notes, include:
- Interest rate, amortization, and maturity
- Prepayment rights/penalties
- Security: collateral, guarantees, or subordination terms
For earn-outs, include:
- Metric definition: revenue vs. EBITDA, and the accounting rules behind it
- Operating covenants: limits on buyer actions that could depress earn-out results
- Reporting and audit rights: access to books and dispute resolution
Example: an earn-out tied to EBITDA can be undermined if the buyer allocates corporate overhead to your former business unit. Without guardrails, the seller may never see the earn-out despite strong sales.
Putting It All Together: The Agreement Should Match the Deal You Think You’re Making
Most sellers don’t lose value because they missed an exotic legal clause. They lose value because the agreement quietly reallocates risk—through vague definitions, one-sided remedies, or post-close economics that weren’t modeled clearly. The best purchase agreements are practical: they anticipate the predictable friction points and resolve them while everyone is still aligned and motivated to close.
If you’re preparing for a sale, the strongest outcomes typically come from running a disciplined process, setting expectations early, and negotiating from a position of proof—not hope. That’s the difference between “signing the buyer’s paper” and driving a transaction that protects the business you’ve built. Many owners start that planning on our seller advisory side, where the goal is to create leverage before the purchase agreement ever hits your inbox.
Northeastern Advisors has guided buyers and sellers through purchase agreement negotiations for over two decades, helping business owners translate headline offers into clear, enforceable terms that protect proceeds, limit post-close exposure, and reduce the odds of last-minute re-trades. If you’re considering a sale and want to pressure-test the key provisions—working capital, indemnities, earn-outs, and transition obligations—experienced deal guidance can make the difference between a smooth closing with predictable outcomes and a contract that creates surprises long after you hand over the keys.
Frequently Asked Questions
What are the most important terms to spell out in the purchase price section (beyond the headline number)?
Break the price into components—cash at close, seller note, rollover equity, contingent/earn-out payments—and define exactly how and when each is paid. Specify any working capital or net debt adjustments, the target calculation method, and who prepares the closing statement. If you don’t define the mechanics and timelines, buyers can use post-close true-ups to effectively reduce price.
How should a business purchase agreement define what’s actually being sold (assets vs. stock, and included/excluded items)?
The agreement should clearly state whether it’s an asset sale or equity sale and include detailed schedules of included assets, excluded assets, and assumed/excluded liabilities. For asset deals, be explicit about contracts, IP, permits, customer lists, inventory, and prepaid expenses—buyers often assume exclusions unless listed. For equity deals, address known liabilities, tax exposures, and any subsidiaries or dormant entities that come with the company.
What working capital language prevents “gotcha” adjustments at closing?
Define “Working Capital” using a consistent accounting basis (GAAP or a specified modified basis) and tie it to a sample calculation exhibit. Set a target based on a representative historical average and specify treatment of unusual items (owner perks, one-time expenses, deferred revenue, aged inventory, AR reserves). Also include a clear dispute process and timeline so the adjustment can’t drag on indefinitely.
What representations and warranties matter most to business owners, and how do you keep them from being overly broad?
Focus on the reps that buyers rely on to underwrite risk—financial statements, taxes, title to assets, IP ownership, key contracts, employment matters, and compliance. Limit scope with materiality qualifiers, knowledge qualifiers, and defined disclosure schedules that match reality (not “to the best of Seller’s knowledge” everywhere). Pair reps with survival periods and caps so a minor issue doesn’t become an open-ended liability.
How do indemnification terms and escrow/holdback provisions typically work, and what should sellers negotiate?
Indemnification sets the rules for post-close claims: caps, baskets/deductibles, survival periods, and exclusions (like fraud) that override limits. Escrow/holdback is the funding mechanism—negotiate the amount, release schedule, and who controls claim decisions. Sellers should push for reasonable caps, shorter survival for general reps, and clear claim notice requirements to avoid “phantom” claims tying up funds.
What earn-out terms belong in the agreement to prevent non-payment or manipulation?
Define the exact metric (revenue, EBITDA, gross profit), the accounting rules, and the reporting cadence, and include examples of calculations. Add operating covenants that prevent the buyer from shifting expenses, changing pricing, or reallocating customers in ways that depress the earn-out. Include audit rights and a fast dispute resolution process—if enforcement is slow or vague, earn-outs routinely underperform.
