Best Practices for Closing a Business Deal: My LOI-to-Wire Playbook

Closing a business deal is the sequenced legal and financial process that turns a signed Letter of Intent into a completed transfer of ownership — LOI, exclusivity, definitive purchase agreement, financing sign-off, funds flow, and post-close Day One — typically running 60 to 120 days from signed LOI to wire. The deal isn’t done when you agree on price. It’s done when the money moves and the keys are in your hand. Everything between those two points is where deals actually die.

Look, most first-time buyers treat closing like a formality. They think the hard part was the negotiation. Then they hit a financing condition they can’t clear, a working capital true-up that eats their equity, or a seller who cools off at week 10 because their attorney found something to worry about. Closing is a discipline, not a ceremony.

I’ve closed 300+ deals over 30 years. The ones that closed on time and on terms did the same things in the same order. Here’s the playbook — the same sequence we walk inside Dealmaker Academy.

The Closing Timeline: LOI to Wire in 60-120 Days

The acquisition closing timeline is the calendar between signed LOI and funded wire — usually 60 days for a clean SBA deal, 90-120 days for a seller-financed lower-middle-market deal with third-party debt. Every week you leave on the clock is a week the seller can get cold feet. Set the schedule at LOI signing, put dates in writing, and hold both sides to them.

The eight blocks every closing runs through, in order:

1. Signed LOI + exclusivity period (day 0-7). Non-binding on price, binding on exclusivity — 60 to 90 days of no-shop protection. Without exclusivity you’re funding due diligence for the next buyer.
2. Due diligence sprint (day 7-45). Financial, legal, customer, operational. Findings feed the purchase agreement.
3. Definitive purchase agreement drafting (day 30-60). Overlap with DD. The SPA is where every DD finding becomes a rep, warranty, indemnity, or purchase price adjustment.
4. Financing commitment locked (day 45-75). Bank commitment letter, SBA authorization, or seller-note terms — signed and non-contingent on new information.
5. Regulatory and third-party consents (day 45-80). Landlord assignments, key customer consents, license transfers, HSR filings if applicable.
6. Signing (day 75-100). Definitive agreement signed. Deposit into escrow. Announced internally only after this point.
7. Closing conditions cleared (day 90-115). Bring-down certificates, final funds flow, working capital estimate agreed.
8. Wire and possession (day 100-120). Funds move, stock or asset transfer executes, keys hand over. Day One begins the moment the wire clears.

Build the timeline backwards from your ideal Day One and share it with counsel, lender, and seller at LOI. Everyone missing a date owes the room an explanation.

The LOI Is a Term Sheet, Not a Handshake

A well-written Letter of Intent locks price, structure, exclusivity, and closing timeline in enough detail that the definitive agreement becomes a drafting exercise, not a re-negotiation. Vague LOIs get re-traded at week 8. Tight LOIs close on the schedule you set.

What has to be in the LOI before you sign it:

• Purchase price and structure. Total consideration, cash at close, seller financing terms, earn-out framework, escrow amount and duration.
• Working capital target. The dollar amount of working capital delivered at close, with a true-up mechanic post-close. Skip this and the seller can strip out cash on the way out.
• Exclusivity period. 60 to 90 days minimum, with an extension mechanic if third-party consents delay closing.
• Conditions to close. Financing, board approval, key employee retention, landlord consent, regulatory approval — list them, don’t leave them implied.
• Break-up fees and expense reimbursement. Who pays what if the deal dies for cause.
• Closing date target. A calendar date, not “as soon as practicable.”

The LOI is where you spend your leverage. Once signed, you’re on the seller’s field.

Definitive Purchase Agreement: Every DD Finding Becomes a Line

The Stock Purchase Agreement or Asset Purchase Agreement is the binding contract that converts due diligence findings into legal protection — reps and warranties, indemnity caps, escrow holdbacks, purchase price adjustments, and closing conditions. This is the one document where amateur buyers cede the most ground, because they let their attorney negotiate it in a vacuum instead of walking every DD finding through it themselves.

How to make the SPA earn its fee:

• Reps and warranties. The seller warrants the state of the business at signing and again at closing. Every DD flag — customer contract assignability, tax exposure, litigation, IP ownership — should have a specific rep behind it.
• Indemnity cap and basket. How much can you claw back if a rep turns out to be false? Standard is a 10-15% cap of purchase price, with a $25-50K deductible basket. Push for higher for known risk areas.
• Escrow holdback. 10-15% of purchase price parked with an escrow agent for 12-24 months. Covers indemnity claims. The seller will hate it. You need it.
• Purchase price adjustments. Working capital true-up, cash-free/debt-free adjustments, transaction expenses. These usually move 3-8% of purchase price at closing — don’t wave them off.
• Closing conditions. What has to be true at closing for you to be obligated to wire. Financing, key employee agreements, landlord consent, no material adverse change (MAC clause). Missing conditions become bring-down obligations.
• Termination rights. The specific circumstances under which either side can walk without penalty. Financing failure and MAC events are the two you must have.

Walk the SPA with your attorney line by line before signing. If they can’t tie every clause back to something you asked for, they’re negotiating for themselves, not for you.

Clear the Financing Contingency First

Financing is the closing condition that kills more deals in weeks 6-10 than any other single factor — lender surprises, appraisal gaps, personal guaranty issues, or last-minute underwriting changes on the seller’s numbers. Lock financing before you spend legal fees on the SPA. Reverse that order and you’ll pay $30-60K in legal on a deal that dies at underwriting.

The financing steps every closing needs in order:

1. Term sheet from lender within 14 days of LOI. Not a “we’re interested” email. A signed term sheet with rate, term, amortization, personal guaranty, and closing conditions.
2. Full underwriting package to lender by day 30. Three years of tax returns, YTD financials, projections, personal financial statement, resume, use of funds. Delays here compound.
3. Third-party reports commissioned by day 45. Business valuation, environmental (if real estate), quality of earnings if lender requires. Each one takes 3-4 weeks.
4. Credit committee approval by day 60. Written approval, not verbal. Verbal approvals unwind at the last credit meeting.
5. Bank commitment letter, non-contingent, by day 70. This is what removes the financing contingency from the SPA.
6. Closing checklist from lender by day 85. Everything they need to fund — signed docs, insurance certificates, entity formation, EIN, corporate resolutions.

SBA-financed deals add 15-30 days to this timeline. Bank it into the schedule at LOI.

Working Capital Is Where the Deal Actually Bleeds

The working capital adjustment is the closing mechanic that ensures the buyer receives a business with enough current assets — cash, AR, inventory, minus AP and accrued liabilities — to operate Day One without an equity infusion. Miss this at LOI and you’ll wire the full price and discover you also owe $200K to fund payroll on Monday.

How I structure working capital protection in every deal:

• Target working capital at LOI. Trailing 12-month average, adjusted for seasonality. Both sides agree on the target before drafting the SPA.
• Delivery obligation at close. Seller delivers at least the target on the closing balance sheet.
• Post-close true-up. Within 60-90 days of close, both sides produce a closing balance sheet. Difference gets paid in cash — buyer to seller or seller to buyer.
• Escrow to secure the true-up. 3-5% of purchase price held specifically for the working capital adjustment, released after the true-up is final.
• Dispute mechanic. If the parties can’t agree on the closing balance sheet, an independent accounting firm arbitrates. Written in the SPA.

Working capital is the single most re-traded item at signing. Set it early, defend it hard.

The Closing Checklist: 30 Items That Have to Be True on Wire Day

A closing checklist is the master list of every document, consent, filing, and approval that must be executed and in escrow before funds can flow — typically 25-40 line items on a mid-market deal. Every closing that runs late runs late because one line item nobody was tracking wasn’t ready. Assign an owner and a due date to every line.

The categories every closing checklist needs:

• Corporate authorization. Board resolutions, member consents, shareholder approvals — both sides.
• Third-party consents. Landlord estoppels and assignments, key customer consents, key vendor consents, license transfers.
• Financing documents. Loan agreement, security agreement, personal guaranty, subordination agreements with any seller note.
• Insurance. Rep and warranty insurance binder if applicable, general liability, key-person policies, tail policies on prior claims.
• Employment. Executed employment agreements for key employees, non-competes, seller transition agreement, executed retention bonuses if any.
• Regulatory. HSR clearance if applicable, state and federal license transfers, professional license approvals, franchise transfer approvals.
• Tax. 338(h)(10) or 336(e) election if applicable, sales tax certificates, payroll tax clearance, transfer tax filings.
• Bring-down certificates. Officer certificate at close confirming reps and warranties remain true, no MAC event, all covenants performed.
• Funds flow. Signed funds flow memo showing every wire, payoff, escrow deposit, and distribution.

Distribute the checklist to counsel, lender, seller, and seller’s counsel at signing. Review it every Tuesday and Thursday until close.

Day One: What Has to Happen the Moment the Wire Clears

Day One is the operational transition that begins when funds flow — bank accounts changed, insurance active, keys transferred, payroll assumed, and a communication plan executed with employees, customers, and vendors within the first business day. A messy Day One erodes six months of goodwill you paid for.

The Day One checklist I run on every close:

1. New bank accounts operational. Payroll, AR, AP, operating — all in the new entity’s name, funded, with signatories in place.
2. Insurance policies bound. Bind before close, effective the moment ownership transfers. Do not rely on the seller’s policy.
3. Employee announcement, in person if possible. Same day the deal closes. Explain what’s changing (usually little) and what’s not (usually most). Introduce yourself.
4. Top 10 customer calls, week one. Personal calls, not emails. Reassurance is a leadership function.
5. Payroll cutover confirmed. The first payroll under new ownership runs without a hitch. This is a Day One credibility test.
6. Vendor notifications with new payment instructions. AP change letter to every material vendor with new bank details and contact.
7. Systems access. You get admin credentials on every system — accounting, CRM, banking, email, domain, cloud storage — before the wire lands.

Day One is a leadership moment. Rehearse it before it happens.

How Negotiation Discipline Feeds Closing Discipline

Everything in this closing playbook only works if the underlying negotiation strategies for buying a business put real protections in the LOI first. A tight closing runs on tight terms. A loose LOI becomes a loose closing and a re-traded price at week 10.

• Anchor terms at LOI — seller financing, escrow, working capital target — so they don’t get renegotiated in the SPA.
• Package trade concessions — never give on price without pulling on terms, escrow, or closing timeline.
• Set the walk-away in writing before signing exclusivity, and hold it through the SPA negotiation.

Frequently Asked Questions

How long does it take to close a business acquisition?

Sixty to 120 days from signed LOI to funded wire is the normal range. Clean SBA-backed deals close closer to 60-90 days. Larger deals with third-party debt, HSR filings, or seller financing tend to run 90-120 days. Anything past 120 days is usually a warning sign — either financing isn’t tracking or the SPA is being re-traded.

What are the main steps in closing a business deal?

Signed LOI with exclusivity, due diligence sprint, definitive purchase agreement drafting, financing commitment locked, third-party consents secured, signing with escrow deposit, closing conditions cleared with bring-down certificates, and funds flow and wire on closing day. Every step has a calendar target set at LOI signing and reviewed weekly.

What has to be in the Letter of Intent to protect the buyer?

Purchase price and structure, working capital target with a true-up mechanic, 60-90 day exclusivity, listed conditions to close, break-up fees, and a calendar closing date. The LOI is where you spend your leverage. Once signed, you’re negotiating on the seller’s field.

What kills a business acquisition between LOI and close?

Financing surprises in weeks 6-10, working capital shortfalls the buyer discovers too late, third-party consents that never materialize, undisclosed liabilities that surface in DD, and seller cold feet in week 8 or 9. Weekly checklist reviews and a real closing timeline are the antidote to all five.

How does the working capital adjustment work at closing?

Both sides agree on a target working capital at LOI — usually a trailing 12-month average. The seller delivers at least that target on the closing balance sheet. Within 60-90 days of close, both sides reconcile the actual balance sheet and true up the difference in cash. A 3-5% escrow holdback secures the true-up.

Should the buyer or seller draft the purchase agreement?

The buyer’s counsel drafts the definitive agreement in most acquisitions. Drafting is a form of control — the first draft sets the framework for every subsequent negotiation. Yes, the seller’s counsel will mark it up, but the buyer’s structure holds most of the time.

What is a closing checklist and who owns it?

A closing checklist is the master tracker of every document, consent, filing, and approval that must be true at closing — typically 25-40 line items. The buyer’s counsel usually owns it. Distribute it to lender, seller, and seller’s counsel at signing and review it every Tuesday and Thursday until close.

How do I handle Day One after the wire clears?

Bank accounts operational, insurance bound the moment ownership transfers, employee announcement in person the same day, top 10 customer calls in week one, first payroll under new ownership running clean, vendor notifications with new payment instructions, and admin credentials on every system in your hands before the wire lands. Rehearse Day One before it happens.
