From LOI to Purchase Agreement: What Sellers Should Expect to Negotiate Twice

Many Phoenix business sellers believe that signing a Letter of Intent (LOI) commits the buyer to the deal terms. In reality, the LOI opens negotiations on a second front: the final Purchase Agreement often re-trades critical deal points that sellers thought were settled.
From LOI to Purchase Agreement: What Sellers Should Expect to Negotiate Twice
Many Phoenix business sellers believe that signing a Letter of Intent (LOI) commits the buyer to the deal terms. In reality, the LOI opens negotiations on a second front: the final Purchase Agreement often re-trades critical deal points that sellers thought were settled.
Understanding what gets re-traded—and which concessions to guard against—is essential for protecting your exit price and limiting liability after close.
The LOI Is Not the Deal
An LOI is a preliminary expression of intent. It signals that buyer and seller have aligned on price, the general business being sold, and the proposed closing timeline. But it is **not binding** on the economic or liability terms that matter most to a seller.
The LOI typically runs 3 to 7 pages. The final Purchase Agreement (or Definitive Purchase Agreement, "DPA") runs 30 to 80 pages. That difference reflects legal precision: the LOI is a conceptual framework; the DPA is the binding contract that specifies what happens if something goes wrong, what the buyer gets credit for, and what financial responsibility falls to the seller.
The gap between these two documents creates a second negotiation window—one that many sellers find unexpected or frustrating.
Why Buyers Re-Trade in the DPA
Buyers typically come back to the table during the DPA drafting phase because their lender, insurance broker, or legal counsel flags new concerns. More often, the buyer's attorney simply tightens terms in ways the buyer's broker never disclosed.
Common re-trades include:
**Working Capital Adjustments.** The LOI may state that the buyer assumes "the business as is" or agrees to a ballpark working capital figure. The DPA then specifies exactly how that working capital is calculated (inventory, accounts receivable, payables, accrued expenses), often with the buyer holding back escrow or a purchase price adjustment if the closing balance sheet doesn't match the projected number. Sellers frequently discover that the definition of working capital they thought was settled now includes line-item exclusions they never anticipated.
**Indemnity Caps and Baskets.** Many LOIs acknowledge that the seller will provide reps and warranties (representations and warranties) but don't quantify the cap. The DPA then locks in limits: "Seller indemnifies Buyer for breaches of reps and warranties, capped at 10% of purchase price" or capped at a specific escrow holdback. Sellers often find this number lower than they'd hoped, or they learn for the first time that certain reps (like tax compliance or environmental liability) carry higher or uncapped exposure.
**Non-Compete Scope.** The LOI often states simply that "Seller agrees to a non-compete." The DPA then specifies radius (3, 5, 10 miles?), term (1, 2, 5 years?), and carve-outs (what if you want to buy a franchise in an adjacent market? what if you consult part-time for a related business?). Sellers routinely negotiate less restrictive terms here because they didn't understand how tight the initial agreement could become.
**Earn-Out Conditions.** If part of the purchase price is contingent on future performance, the LOI may outline this conceptually. The DPA then defines the measurement period, the calculation method, the buyer's role in maintaining revenue, and dispute resolution. Sellers often learn that earn-outs are easier for buyers to reduce than to pay in full.
Which LOI Items Sellers Should Never Agree to Without Legal Review
Before signing the LOI, engage a business attorney. This is not the time to save money on counsel. Certain LOI language should raise a red flag:
**"Full Disclosure" Clauses.** Language stating that the seller must disclose "all material information" or "anything an ordinary buyer would want to know" is dangerously vague. Insist on a specific schedule of disclosures and define "material" (e.g., losses over $25,000, customer attrition over 20%, or known litigation). This prevents post-close disputes where the buyer claims you should have disclosed something you didn't even know was relevant.
**Seller Financing with Broad Recourse.** If the buyer is asking the seller to finance part of the purchase, the LOI should clearly state whether the note is recourse (the buyer can come after your personal assets if they default) or non-recourse (the seller's remedy is only the note itself). Non-recourse is significantly more protective and should be specified in the LOI—not left to be decided later in the DPA.
**"Knowledge" Qualifiers Without Definition.** Reps and warranties often come with carve-outs like "to the best of Seller's knowledge." The DPA will try to narrow what "knowledge" means. Lock this down in the LOI: does it mean personal knowledge of named principals only, or does it include knowledge of any employee? This distinction can save you from indemnity claims based on information someone else knew.
**Indemnity Terms with No Cap.** The LOI should state that indemnity claims are capped at some percentage of the purchase price and that there is a basket or threshold below which claims don't trigger (e.g., claims under $10,000 don't count). If the LOI says indemnity is "unlimited," you're exposed indefinitely post-close.
**Indefinite Earn-Outs or Earnest Money Holdback.** If the DPA will allow the buyer to hold funds "until financial statements are finalized" or "for up to 18 months," the LOI should specify the exact window and calculation method. Vague language here invites the buyer to delay payout or challenge what counts toward the threshold.
Practical Steps to Reduce Re-Trading Friction
**Get Specific Early.** In LOI negotiations, push for specificity on indemnity caps, non-compete scope, working capital definitions, and earnest money or escrow percentages. The more detailed the LOI, the less re-trading happens later.
**Involve Your Broker and Attorney in Parallel.** Your business broker has seen dozens of deals and knows which terms tend to come back for re-negotiation. Your attorney ensures your protections are tight. Both should review the LOI before you sign.
**Request the Buyer's Form DPA.** Many buyers have a standard Purchase Agreement template. Ask for it during LOI negotiations and review it with your attorney. Surprises in the DPA are far easier to address when you've seen the buyer's template in advance, rather than discovering them for the first time during the binding agreement phase.
**Reserve the Right to Adjust Escrow Timing.** If the buyer wants to hold escrow (earnest money or indemnity holdback) beyond the close, negotiate the release schedule in the LOI. Specify that funds are released on (for example) the 12-month anniversary if no claims are pending, not "when the buyer feels comfortable."
Eddy Roche, Associate Broker at HUB AZ Brokers | Sunbelt Business Brokers, advises: "The LOI gets you to the table, but the DPA is where you really find out what you're selling and what you're keeping paying for. By the time an attorney is drafting indemnity caps, it's too late to reset expectations. Pin down the key terms in the LOI and get legal eyes on it before you sign."
The Takeaway
The LOI is the announcement that a deal is probable, not the confirmation that the deal is done on your terms. Between LOI and Purchase Agreement, the buyer's legal team—and sometimes the lender or insurance broker—will re-trade working capital definitions, indemnity exposure, non-compete scope, and escrow terms.
Sellers who understand this dynamic come better prepared. They specify terms upfront, engage legal counsel early, and they review the buyer's form DPA before agreeing to the LOI. These steps don't eliminate re-trading, but they shift the balance of negotiating power back to the seller.

Frequently Asked Questions
Is a Letter of Intent legally binding?
In most cases, no. An LOI expresses intent to move forward and signals agreement on price and basic deal structure, but it is not a binding contract. The real binding agreement is the Definitive Purchase Agreement (DPA), which comes later and often includes different terms than the LOI.
What is a working capital adjustment in a business sale?
Working capital is the buyer's estimate of cash, inventory, and receivables needed to operate the business on day one. The DPA specifies how this is calculated and whether the buyer gets a credit or holdback if the closing balance sheet differs from the projected amount. This often becomes a re-traded point after the LOI is signed.
What should I look for in an indemnity clause?
An indemnity clause protects the buyer if the seller's representations and warranties are false. Sellers should ensure the LOI specifies a cap (usually 10–15% of purchase price), a basket or threshold (claims below $25,000 don't trigger), and a time limit for bringing claims (typically 12–24 months post-close). Avoid 'unlimited' indemnity exposure.
Can a seller renegotiate the non-compete after the LOI?
Yes. The LOI often states only that a non-compete exists. The DPA then specifies the radius (in miles), term (in years), and any carve-outs. If the LOI doesn't lock in these specifics, the buyer's attorney will propose tighter terms during DPA drafting. Define non-compete scope in the LOI to avoid surprises.
