How to Close a Deal: Business Sale Closing Checklist (Step-by-Step)

If you are learning how to close a deal on a business sale, start with this: deals rarely die from fires or floods. They die because of the people involved, a vague agreement, a surprise in due diligence, an advisor who isn’t focused on getting to the finish line. After more than 35 years of closing confidential sales across Arizona, we use a checklist that keeps those risks in view from the first conversation to the last signature.

Overview: What “Closing a Deal” Means in a Business Sale

Closing is the moment ownership changes hands and money moves. Most small business sales are asset sales, where the buyer purchases equipment, inventory, goodwill and contracts. Larger or entity-heavy deals may be stock sales, where the buyer buys the company itself. A typical sale involves the buyer, the seller, the business broker, a lender, an escrow or closing agent, and each side’s CPA and attorney. From accepted letter of intent to closing, timing depends on financing, landlord approvals and how ready the seller’s records are, so no one can promise a date in advance. Learn how we help owners sell a business.

Step 1: Align on the LOI and Key Terms

In too many cases, the buyer and seller really weren’t in agreement, or didn’t understand the terms of the sale. If a letter of intent is too vague or has too many loose ends, the sale can unravel somewhere along the line.

Put the big items in writing now: price and how it is paid (cash, bank loan, seller note, earn-out), the allocation between equipment and goodwill, the non-compete, how long the seller will train the buyer, the target closing date and who will act as escrow agent. Start from a defensible business valuation, and see our article on the letter of intent to sell a business for what a strong LOI contains.

Step 2: Work Through the Due Diligence Checklist

The seller has to be up front about the business. Nothing is perfect, and buyers understand this. The minuses should be revealed at the outset, because sooner or later they will be exposed.

Expect the buyer to review three or more years of tax returns and financial statements, sales tax filings, bank statements, leases, licenses and permits, major customer and vendor contracts, employee records, equipment lists and inventory. Sellers can speed this up by preparing a data room before listing. Our guide to the documents you need to sell a business in Arizona works as a starting list.

Due diligence goes both ways. The seller may have questions about the buyer’s financial qualifications or ability to run the business, especially if the seller is carrying a note. Raise those concerns now. When a question comes up that the seller can’t answer quickly, say so and give a date, rather than letting it sit. Silence during due diligence makes buyers nervous, and nervous buyers start renegotiating.

Step 3: Line Up Financing and Proof of Funds

If financing is an issue, it should be mentioned at the beginning, not discovered in week six. Cash buyers should show proof of funds. Buyers using an SBA loan will need a lender’s commitment, and the lender will usually verify the seller’s tax returns directly with the IRS using Form 4506-C. Larger deals may also require a quality of earnings review by an outside accountant.

Seller financing often fills the gap between the loan and the price. If you still owe on your own SBA loan, read can you sell your business if you have an SBA loan.

Step 4: Draft the Definitive Purchase Agreement

The purchase agreement turns the LOI into a binding contract. It covers representations and warranties, the schedules of assets and contracts, indemnities, any working capital target, and the price allocation. In an asset sale, buyer and seller each file IRS Form 8594 reporting that allocation, so agree on it in the contract. Our guide on how to write a contract for selling a business walks through the key clauses.

Representations and warranties are the seller’s written promises about the business: the financials are accurate, there are no undisclosed lawsuits, the equipment is owned free of liens. Indemnities say who pays if one of those promises turns out to be wrong. Attorneys tend to spend the most time here, and a broker’s job is to keep the negotiation focused on real risks rather than every hypothetical.

Step 5: Get Third-Party Consents and Assignments

Many closings stall here. The landlord must approve a lease assignment or sign a new lease. A franchisor must approve the buyer. Key vendors, equipment lessors and customers with assignment clauses may need to sign off. Licenses and permits may need new applications.

Arizona examples include contractor licenses through the Registrar of Contractors, which generally do not simply transfer to a new owner, and liquor licenses through the Department of Liquor Licenses and Control. Start these requests as soon as the purchase agreement is signed.

Landlords move at their own pace. Many will want the buyer’s financial statement, a personal guarantee and sometimes a new lease form. Getting the landlord’s attorney involved early, with the seller making the introduction, often saves weeks.

Step 6: Satisfy Pre-Close Conditions and Contingencies

Typical conditions include a lender’s appraisal, UCC and lien searches, a final inventory count, a signed training and transition plan, and confirmation that nothing material has changed. Arizona can hold a buyer responsible for a seller’s unpaid transaction privilege tax, so buyers often ask for a clearance from the Arizona Department of Revenue or hold funds in escrow until it arrives.

Both sides need to understand that this stage takes time. There is a myriad of details that must take place for the sale to close at all.

Step 7: Escrow Mechanics and Funds Flow

The escrow or closing agent works from written escrow instructions. Before closing, everyone reviews the settlement statement: purchase price, deposits, loan proceeds, payoffs of the seller’s debts and liens, prorations for rent and utilities, broker fees and any holdbacks. Confirm wire instructions by phone, never by email alone, and note the bank’s wire cutoff time.

The buyer and seller should insist that outside advisors keep to the scheduled closing date. Before engaging them, make sure they can work within the schedule, and remember that the advisors work for you; most decisions in the sale are business decisions for the buyer and seller to make.

Step 8: Closing Day Checklist

On closing day, the seller hands over:

• Keys, alarm codes and access cards
• Passwords and admin access for email, software, the point-of-sale system and the website domain
• Changes to bank account signers or new merchant accounts
• Proof of the buyer’s insurance in force, with binders effective that day
• Signed bills of sale, assignments, the non-compete and any seller note documents

Step 9: Post-Close Tasks (First 30 to 90 Days)

Notify employees, customers and vendors, ideally with buyer and seller together. Set up payroll under the new owner, register for Arizona transaction privilege tax and other accounts, introduce the buyer to key suppliers, and follow the training plan. Keep an eye on any holdbacks or seller-note payments, and keep copies of every closing document.

Sellers have a list too: close out or transfer utility accounts, file final sales tax and payroll returns for the period before closing, cancel or assign insurance policies as agreed, and keep records the buyer may need for the first tax year. If you agreed to stay on for training, put the hours on the calendar so neither side is guessing.
