M&A Legal Purchase Agreements

Business Purchase Agreement:
The Most Important Document in Your Deal

The LOI was the plan. Due diligence was the research. The purchase agreement is where deals are actually won or lost. Here's what every buyer and seller needs to know before signing.

By Alex Lubyansky, Esq. • 20 min read • Updated October 20, 2026

A business purchase agreement sets the binding terms for transferring specified business assets or ownership interests from seller to buyer. Signing and completing the transfer can occur at different times. It sets the purchase price, identifies the assets or stock being acquired, and spells out the representations, warranties, indemnities and closing terms that protect both sides. This guide covers the 12 sections every business purchase agreement should include, from purchase price structure through dispute resolution.

Key Takeaways

A business purchase agreement records what the parties have agreed to acquire, the price, their obligations and the conditions for closing. Read it alongside the LOI and related documents rather than assuming all earlier commitments disappear.

If seller transition support matters to the transaction, identify the work, duration, payment and responsibilities in the proposed documents. Compare the expectation with the actual obligations in the draft before relying on the seller’s help.

Ask counsel how the purchase agreement addresses prior statements, related documents and the parties' intended obligations. Integration, reliance and remedy provisions require review in the context of the actual transaction and governing law.

This guide covers every section that belongs in a business purchase agreement - whether you're buying a $2 million manufacturing company or selling a $30 million SaaS business. It's written for both sides of the table, because understanding the other side's priorities is how you negotiate better terms for yours.

What Is a Business Purchase Agreement?

A business purchase agreement sets the binding terms for transferring specified business assets or ownership interests from seller to buyer. Signing and completing the transfer can occur at different times. It's called different things depending on the deal structure - asset purchase agreement, stock purchase agreement, membership interest purchase agreement - but the function is the same: define exactly what's changing hands, for how much, under what conditions, and with what protections.

The letter of intent sets the preliminary terms, diligence tests the underlying business and the purchase agreement states the obligations the parties are prepared to sign. Compare all three before treating a business point as resolved. An issue identified during diligence may need further investigation, a disclosure, a negotiated protection or a decision about whether to proceed.

The First Decision: Asset Purchase vs. Stock Purchase

Before you draft a single word, you need to answer one structural question: are you buying the company's assets or the company itself?

The choice between an asset purchase and an ownership-interest purchase changes which assets and liabilities move, which consents may be needed and how tax consequences should be modeled. Compare the proposed structure against the actual entity and business records.

Factor Asset Purchase Stock Purchase
What transfers Specific assets you select Entire entity (everything)
Liability exposure Only assumed liabilities All liabilities (known + unknown)
Tax: Buyer Stepped-up basis (favorable) Carryover basis (less favorable)
Tax: Seller Potential double taxation Seller tax treatment depends on the structure and basis
Third-party consents May need re-assignment of contracts Contracts stay in place
Complexity Higher (itemize everything) Lower (buy the whole entity)
Employees Must rehire (new employment) Employment continues
Who prefers it Buyers seeking identified assets and negotiated liability allocation Sellers (cleaner exit)

For a deeper dive into asset purchase mechanics - including purchased assets schedules, excluded liabilities, and Section 1060 allocation - read our complete asset purchase agreement guide. For a full comparison of both structures with tax implications, LLC considerations, and Section 338(h)(10) elections, see our asset purchase vs. stock purchase guide.

An LLC interest purchase requires its own legal and tax analysis. Ask the tax adviser to evaluate the entity’s classification, any relevant elections and the allocation consequences rather than assuming an interest purchase receives asset-purchase tax treatment. Counsel should align the documents with the structure the advisers have actually evaluated.

The 12 Sections Every Business Purchase Agreement Must Include

The sections below identify common purchase-agreement decisions. Counsel should evaluate which provisions and supporting documents the actual structure requires, including material issues that a form leaves unresolved. If you want a starting point for drafting, see our business purchase agreement template, which walks through the same sections with sample language.

1

Purchase Price and Payment Structure

This is more than just a number. The purchase price section defines total consideration, how it's split between cash at closing, seller financing, earnouts, and escrow holdbacks. It should specify:

Watch out. Define when escrow funds can be released, how a claim affects release and who must give the relevant instructions. Check those terms against the escrow agreement.

2

Asset or Stock Identification

In an asset deal, this section specifies every asset being purchased and every asset being excluded - typically through detailed schedules. In a stock deal, it identifies the shares or membership interests being transferred.

Identify included and excluded assets precisely. Reconcile the schedules with equipment, intellectual-property and contract records so a broad phrase such as "substantially all assets" leaves fewer ownership questions for closing. See asset purchase agreement guide.

3

Representations and Warranties

Representations are factual statements each party makes about themselves and the business. Warranties are promises that those facts are true. Together, they create the legal basis for indemnification claims after closing.

Seller representations can address organization, authority, financial records, taxes, intellectual property, compliance and disputes. Buyers also make representations appropriate to their obligations. Identify which representations receive special treatment under the actual cap, survival and remedy provisions. See fundamental representations.

The negotiation here is about scope and qualifiers. Sellers want to narrow their reps with "to the best of our knowledge" and "in all material respects." Buyers want unqualified, sweeping representations. The compromise shapes your entire post-closing risk profile. We go deep on this in our representations and warranties guide.

4

Indemnification Provisions

Indemnification is one part of the negotiated remedy framework. Review its caps, baskets, survival periods and exclusions alongside any exclusive-remedy clause, other contractual rights and applicable law. Confirm which remedies remain available under this agreement and its governing law.

The three numbers that matter most:

Cap
Contractual liability cap. The negotiated cap, exclusions and any special limits determine the contractual position.
Basket
Minimum threshold before claims trigger. Specify the negotiated threshold and its exceptions. "Tipping" baskets (first-dollar recovery) favor buyers.
Survival Period
How long you can bring claims. Specify the agreed claim period, notice process, exceptions and governing-law limits.

Read the cap, basket, survival period and claim exceptions together. A deductible and a tipping basket allocate small claims differently, and longer survival can affect when a claim may be made. Model plausible losses against the complete remedy framework before accepting any limit.

5

Closing Conditions

Closing conditions are the gates that must open before the deal can close. They protect both sides from being forced to close when circumstances have changed. Standard conditions include:

6

Non-Compete and Non-Solicitation

A proposed seller covenant addresses competitive activity after closing. A non-solicitation clause addresses defined approaches to customers, employees or other relationships. Review each party bound, restricted conduct, duration, territory and applicable law before relying on either protection.

Review the restricted activity, geography, duration and persons bound under the applicable law. Sale-related restrictions and employment restrictions can require separate analysis, even when the seller continues working after closing.

The buyer needs to identify the goodwill and relationships being acquired. The seller needs to understand how the draft affects future work and retained business interests. Define those activities before asking counsel to assess enforceability and negotiate permitted exceptions.

7

Earnout Provisions

An earnout bridges the gap when buyer and seller disagree on what the business is worth. The seller receives additional payments after closing if the business hits agreed-upon targets - revenue, EBITDA, customer retention, or other metrics.

Earnouts are one of the most contentious post-closing issues in M&A. The critical questions:

Earnout terms deserve careful review because payment depends on the agreed metrics, operating obligations and dispute process. Read our full earnout agreements guide before agreeing to any performance-based payment structure.

8

Working Capital Adjustment

Working capital is the lifeblood that keeps the business operating day-to-day - current assets minus current liabilities. The purchase agreement should specify a "target" working capital amount, and the purchase price adjusts dollar-for-dollar based on the actual working capital delivered at closing.

Compare the expected operating assets and liabilities at closing with the price assumptions. Agree which accounts enter the working-capital calculation, the target, accounting principles and objection process. A price adjustment and an operating covenant serve different purposes; review both with counsel and the accountant. See the working capital adjustment guide for the calculation and true-up questions.

9

Escrow Arrangements

An escrow can hold an agreed amount with a third party to support specified post-closing obligations. Define the permitted claims, notice process, release instructions and disputed-amount treatment in documents that align with the purchase agreement.

Negotiate the escrow amount, release schedule (lump sum vs. staged), conditions for release, and what happens to remaining escrow after the survival period expires. Sellers want the smallest escrow possible with the fastest release. Buyers want a larger escrow held for the full survival period.

10

Transition Services

A transition services agreement (TSA) defines any operational support after closing, such as introductions, training, systems access and vendor handoffs. Identify the provider, services, duration, compensation and exit plan so the business can operate through the transition.

Define the proposed transition services, who provides them, their duration, any payment and the agreed response to nonperformance. Coordinate the purchase agreement with any separate transition-services document.

11

Confidentiality

Both parties have learned extensive confidential information about each other during due diligence. The confidentiality section survives closing and prevents either side from disclosing deal terms, proprietary business information, or trade secrets. If the deal falls apart before closing, confidentiality provisions protect the seller's sensitive information from being used by the buyer (who may be a competitor or investor in one).

12

Dispute Resolution

The dispute-resolution provisions specify how disagreements will be addressed, including any negotiation, mediation, arbitration or litigation steps. Check governing law, venue, notice requirements, interim relief and responsibility for costs.

Compare forum, confidentiality, discovery, appeal rights, urgency and cost under the actual dispute clause and applicable rules. Counsel should explain whether negotiation or mediation is required before another proceeding and what interim relief remains available. Resolve those choices before signing rather than assuming one process is always faster or more suitable. This same framework applies to business divorce buyouts where partner disputes are resolved through structured purchase agreements.

Purchase Price Allocation: The Tax Clause Nobody Reads

Purchase price allocation determines how the total purchase price is distributed across different asset categories for tax purposes. For qualifying asset acquisitions, the IRS instructions for Form 8594 explain the allocation and reporting requirements for buyer and seller. Inconsistent reporting requires tax-adviser review and can create tax exposure.

Purchase price allocation can produce different tax consequences for buyer and seller. Have the tax advisers model the actual assets, entity structure, tax basis and applicable law before agreeing to the allocation schedule.

Buyers Want

Identify which acquired assets have a depreciable or amortizable basis and ask the tax adviser to model the actual deduction rules, timing and limitations. Equipment, goodwill and other asset classes can receive different treatment.

Ask the tax adviser which depreciation rules and asset lives apply to the equipment actually acquired. Have the tax adviser model those assets rather than assuming one deduction schedule fits all equipment.

Sellers Want

Ask the tax adviser to determine the character and timing of gain for each transferred asset, including goodwill, and any recapture. Entity structure, tax basis and the transaction steps can affect the result; the asset’s label alone leaves those questions unresolved.

Ask the tax adviser how goodwill proceeds and any depreciation recapture are taxed for this seller and transaction structure. Model federal and state consequences with the tax adviser before agreeing to allocation.

The allocation should be negotiated before closing and memorialized in the purchase agreement. Leaving it to "mutual agreement after closing" is a recipe for post-closing disputes and inconsistent tax filings. For the full breakdown of all 7 IRS asset classes, buyer vs. seller incentives, and common mistakes, read our complete purchase price allocation guide.

Your attorney addresses the allocation provisions and your tax adviser models the tax consequences. Coordinate their assumptions before signing so the legal documents reflect the agreed economic treatment.

7 Purchase Agreement Issues to Resolve Before Signing

1. Rushing to Close Without Reviewing Reps and Warranties

Before signing, compare the representations with diligence findings and disclosure schedules. Identify qualifications, exceptions and any unresolved factual question. Counsel should explain the available contractual remedies and their limits so a desire to finish negotiations leaves material exposure visible.

2. Inadequate Indemnification Caps and Survival Periods

Read the proposed cap and survival period together with claim-notice requirements, exceptions and other remedy provisions. A general indemnity limit does not by itself answer how every potential claim will be treated.

3. Ignoring Working Capital Adjustments

Ask the accountant to identify the operating capital the buyer expects to receive and reconcile it with the draft’s included and excluded accounts. Counsel can review the target, calculation, notice process and any interim operating covenant. Missing language requires a transaction-specific response rather than an assumption that the seller will misuse the business.

4. No Earnout Protection Mechanisms

Changes to pricing, operations or customer assignments can affect the earnout calculation. Review the negotiated operating covenants, reporting rights and remedies with counsel before concluding how those changes affect payment. Buyers need measurable payment terms that also address planned operational changes.

5. Weak Non-Compete Language

Have counsel evaluate the proposed non-compete under the applicable law, qualifying sale and actual restricted activity. Document the sold business’s territory and goodwill, the people bound and any activities the seller retains. A template leaves those transaction-specific questions unresolved.

6. Leaving Purchase Price Allocation to Post-Closing

Resolve the allocation process, supporting assumptions and reporting responsibilities with the tax advisers before closing. If the final amounts remain subject to adjustment, specify how the parties determine and report them consistently. The IRS Form 8594 instructions explain reporting for qualifying asset acquisitions.

7. Choosing Counsel Without Checking the Proposed Scope

Ask the proposed attorney about purchase-agreement experience relevant to your deal, including indemnity mechanics, allocation, working capital and the diligence findings. Existing business counsel may be appropriate when their experience and specialist coverage fit the work.

From LOI to Purchase Agreement: What Happens in Between

You've signed the letter of intent. Now what?

The period between LOI and purchase agreement is where the real work happens - and where most deals either solidify or fall apart. Here's the typical timeline:

On some Main Street deals, the business broker, not either party's attorney, produces the first draft of the purchase agreement itself. See our guide on reviewing a broker-drafted purchase agreement for what a broker's template typically misses, particularly in stock deals where liabilities travel with the entity.

Diligence phase

Due Diligence

Buyer investigates financials, legal, operations, and compliance. Identify material open questions and decide how to address them. Depending on the issue, the parties may seek more information, negotiate protection or a price change, or reconsider proceeding. (See our due diligence guide)

Initial drafting

First Draft of Purchase Agreement

Buyer's attorney typically drafts the first version. This is the buyer's "wish list" - aggressive indemnification, broad reps, conservative working capital targets. Seller's attorney marks it up, pushes back, and the negotiation begins.

Negotiation

Negotiation Rounds

Plan time for negotiated markups and resolution of open issues. The biggest battles: indemnification caps/baskets, non-compete scope, working capital targets, and earnout mechanics. This is where experienced M&A counsel earns their fee - knowing which provisions to fight for and which to concede.

Supporting documents

Schedules, Exhibits, and Ancillary Documents

The purchase agreement is just the master document. It's supported by asset schedules, disclosure schedules, employment agreements, escrow agreements, and sometimes dozens of exhibits. These ancillary documents often take longer than the main agreement.

Signing and closing

Execution and Closing

Final agreement executed. Closing conditions satisfied. Funds wired. Documents recorded. Ownership transfers. Then the post-closing phase begins: working capital true-up under the agreed timetable, transition services, and earnout measurement periods. (See our post-LOI checklist)

Purchase Agreement Review Questions

What is a business purchase agreement?

A business purchase agreement sets the terms for acquiring specified assets, stock or membership interests. It addresses the price, payment terms, representations, obligations, closing conditions and agreed treatment of risk. Signing and completing the ownership transfer can occur at different times.

What is the difference between a letter of intent and a business purchase agreement?

An LOI records proposed terms before the definitive agreement. Do not assume every LOI provision is nonbinding: review its wording, any related agreements and the governing law. The purchase agreement then sets the detailed transaction terms and closing requirements.

What should you bring to a purchase-agreement review?

Bring the current draft, the signed LOI or offer, available schedules and the list of unresolved diligence questions. Identify your role, proposed signing and closing dates, financing status and any terms the parties still disagree about.

For examples under Delaware law, see Delaware Supreme Court, SIGA Technologies v. PharmAthene (December 23, 2015) on obligations arising from preliminary agreements and Delaware Supreme Court, Johnson & Johnson v. Fortis Advisors (January 12, 2026) on negotiated remedy provisions. Apply each decision in its jurisdictional and contractual context.

How to Evaluate Purchase Agreement Counsel

When choosing counsel, ask about experience with the transaction structure, the proposed scope of review, who will handle the work and how unresolved diligence issues will be addressed. Deal value alone does not determine the legal questions that need attention.

Identify who will prepare the first draft, what diligence remains open and which business terms require agreement. That allocation of responsibility helps each adviser focus the review on the buyer’s or seller’s actual exposure.

Ask About Relevant Work

  • • Which similar purchase agreements has the proposed team handled?
  • • Who reviews the indemnity, allocation and working-capital questions?
  • • How will legal review use the accountant’s diligence findings?
  • • Which specialist questions require a separate assignment?

Confirm the Proposed Scope

  • • Identify who drafts, negotiates and reviews final revisions.
  • • Define the documents and closing work included.
  • • Record assumptions, exclusions and additional-work approval.
  • • Confirm availability around the actual signing deadline.

Compare counsel proposals by scope and responsibilities. Ask how the proposed review addresses the provisions and open issues that matter to your transaction. See how to choose a business acquisition lawyer.
