Selling a Business Checklist: What Buyers Verify

There is a version of “getting ready to sell” that starts with a filing cabinet and ends with a neat stack of folders. That version is incomplete.

A selling a business checklist is about paperwork, sure. But the paperwork exists because a buyer and their lender are going to take apart every number, every contract, and every operational dependency before a single dollar moves. The documents are not the point. What the documents prove is the point.

When you understand what goes on that checklist from the buy side, something shifts. You stop thinking about what to gather and start thinking about how clean it needs to be, what gaps will stall a deal, and which missing items will kill one outright.

Here is the selling a business checklist that actually matters, built from what we review on hundreds of deals every year.

Two Sets of Eyes, Two Standards

When a buyer backed by SBA financing makes an offer on your business, your financials do not get reviewed once. They get reviewed twice, independently.

The SBA lender is building a cash flow model to confirm the business can service the debt. They are not just screening for fraud. They are stress-testing whether the numbers hold up under a loan repayment schedule.

The buyer’s advisory team is doing its own version of the same exercise, but they are also asking a different question: does this business hold together after the seller walks away?

So your preparation needs to clear both bars. Sellers who treat due diligence as a paperwork drill often get blindsided when a deal collapses over something their broker called a non-issue.

Financial Records: Where Most Deals Get Stuck

This is the core of the selling a business checklist, and it is where the most time gets burned. Lenders require three years of financial records at minimum. Here is what that looks like in practice.

Tax returns. Three years of business tax returns, signed and filed. If there is a discrepancy between your tax returns and your profit and loss statements, you need a clear explanation ready before the buyer asks for one. Unexplained gaps between reported income and claimed SDE are one of the most common deal-killers we see. Not occasionally. Regularly.

Profit and loss statements. Month-by-month P&Ls for the trailing 36 months, prepared by your accountant. Year-end summaries will not cut it for SBA underwriting.

Balance sheets. Current balance sheet dated within 90 days of the LOI, plus year-end balance sheets for the prior three years.

Bank statements. 12 months of business bank statements. The lender will reconcile deposits against reported revenue. If cash deposits do not match your reported top line, the deal either restructures or dies. There is no middle ground on this one.

Accounts receivable and payable aging. Current AR and AP aging schedules. Heavy concentration in one or two customers shows up here and directly affects how the buyer values the business.

Worth understanding: a business doing $1.5M in revenue with clean, consistent books and no major AR concentration will move through underwriting faster than a $2.5M business with three years of inconsistent records and an explanation required for every line. Size does not override clarity.

Legal and Operational Documents

Once the financials pass initial underwriting, the buyer and their attorney shift into legal and operational due diligence. You need these ready before an LOI is signed. Not after.

Business formation documents. Articles of incorporation or organization, current operating agreement or bylaws, and a certificate of good standing from your state.

Licenses and permits. Every license required to operate, with expiration dates. If any license is non-transferable, that becomes a closing condition, and both attorneys need to plan around it early.

Contracts. Customer contracts, supplier agreements, equipment leases, long-term service agreements. The buyer needs to know which contracts transfer automatically and which require counterparty consent. A major customer contract that requires consent to assign is a genuine risk if that customer decides not to cooperate. We have watched otherwise clean deals stall for weeks over a single consent clause.

Lease agreement. If you operate out of a physical location, lease terms matter more than most sellers realize. Buyers and lenders want to see at least three to five years remaining, or a landlord willing to sign a new lease at closing. A location-dependent business with 12 months left on its lease is a hard deal to finance. Some lenders will not touch it.

Employee records. Organizational chart, employee list with titles and compensation, any employment agreements, and your plan for key employees staying post-close.

All of That Covers What You Submit. Now for the Number That Determines Your Price.

The SDE and EBITDA Calculation

The number on the selling a business checklist that most directly affects what you get paid is your SDE or EBITDA. Sellers should understand how buyers calculate this before the first real conversation.

SDE is earnings before owner compensation, interest, taxes, depreciation, and amortization, adjusted for personal expenses run through the business. For businesses under roughly $2M in asking price, SDE is the standard metric. Larger deals use EBITDA.

A few things sellers consistently get wrong.

Add-backs need documentation. Every single one. If you are adding back a family member’s salary, show the payroll records and explain the role. If you are adding back owner vehicle expenses, show the actual expense and the business use percentage. Unsubstantiated add-backs get rejected by lenders, and from what we have seen, this happens more often than sellers expect.

And the multiple applied to your SDE is not as negotiable as sellers tend to think. SBA underwriting is built around debt service coverage, not just multiples. A deal priced at 3.5x SDE needs to generate enough cash flow to cover debt service on the SBA loan, typically at a 2.0x DSCR or better. If the math does not work at 3.5x, the offer comes in at 3.0x or 2.8x. The broker’s quoted multiple does not override the lender’s math.

Most SDE-based deals we see close between 2.0x and 3.0x. Businesses with strong recurring revenue, low owner dependency, and no customer concentration issues can push toward 3.5x. That is the realistic ceiling for SBA-financed deals. Not a range. A cap.

Owner Dependency: The Risk Most Sellers Underestimate

Buyers are buying a business. Not a job. If the business cannot function without you, that risk gets priced into the offer, sometimes severely.

Here is what flags owner dependency during due diligence:

You are the primary or only relationship with major customers
You hold a required license the buyer cannot replicate (contractor’s license, professional certifications)
Your compensation makes up the majority of the business’s SDE, meaning the business barely covers your salary and produces little beyond it
There are no documented systems, SOPs, or management processes for the buyer to step into

The gap in value is real. A $400K SDE business where the owner handles all client relationships, holds the contractor’s license, and works 60 hours a week is not worth the same as a $400K SDE business with a manager in place, documented processes, and customers under contract. On paper, the SDE is identical. In practice, the second business might command a full turn higher in valuation.

Plan your transition before listing. Buyers and lenders want to see a realistic 90 to 180 day handoff plan. A vague promise that you will “stay involved” does not count.

What a Seller Note Actually Means

Most SBA-financed acquisitions include a seller note. If you have not sold a business before, this part tends to catch sellers off guard, so it is worth addressing directly.

A seller note is a portion of the purchase price the buyer pays you over time rather than at closing. Typical SBA deal structure: 70 to 85% SBA loan, 10% buyer equity, and the balance (usually 5 to 15% of the purchase price) as a seller note.

On SBA deals we structure, the seller note is on full standby for 10 years at 0% interest in more than 90% of cases. Full standby means no payments from the buyer during the standby period. The note gets paid at maturity or when the buyer refinances.

Sellers sometimes treat this as a red flag. It is not. It is standard SBA deal structure, required by the lender to ensure debt service coverage on the primary loan. The note is secured by the business and documented through the purchase agreement.

What belongs on your checklist here: understand the note terms before signing the LOI. Have your attorney review the note structure. Know what triggers early repayment, if anything does.

Due Diligence Timeline: Longer Than You Think

The selling a business checklist is not a one-time task you complete and forget. Due diligence unfolds in phases after an LOI is signed, and it takes longer than most sellers plan for.

A realistic SBA deal timeline from signed LOI to close:

Due diligence period: 30 to 45 days. The buyer’s team reviews all financial and legal documents, asks follow-up questions, and may hire a third-party accountant for a quality of earnings analysis.
SBA lender underwriting: 2 to 4 weeks after due diligence closes. The lender independently underwrites the deal using the same documents you already provided.
SBA approval and commitment letter: 1 to 2 weeks.
Final document preparation and closing: 1 to 2 weeks.

Total: 60 to 90 days minimum. Complex deals or disorganized records push this past 120 days regularly.

Sellers who have their checklist complete before the LOI hits do two things: they reduce the risk of timeline delays, and they reduce the risk of a deal renegotiating on price because a problem surfaced late. That second point matters more than the first. A problem that shows up in week six of due diligence gives the buyer leverage to reopen the price conversation. A problem disclosed upfront gets factored into the original offer, which is a much better position for the seller.

Frequently Asked Questions

What documents do I need to sell my business?

At minimum: three years of signed business tax returns, monthly profit and loss statements for the trailing 36 months, current and historical balance sheets, 12 months of bank statements, all business licenses and permits, your lease agreement, customer and supplier contracts, and current accounts receivable and payable aging reports. Having these organized before you list accelerates due diligence significantly.

How long does selling a business take?

A business sale using SBA financing typically takes 60 to 90 days from a signed letter of intent to closing. This includes the buyer’s due diligence period (30 to 45 days), SBA lender underwriting (2 to 4 weeks), and final document preparation. Sellers with clean, organized records consistently close faster than those scrambling to produce documents mid-process.

What is seller discretionary earnings and why does it matter?

SDE is the primary valuation metric for small business sales under roughly $2M in asking price. It represents the total financial benefit to a single owner-operator, including salary, profit, and personal expenses run through the business. Most SDE-based deals close at 2.0x to 3.0x SDE, with businesses showing strong recurring revenue and low owner dependency pushing toward 3.5x, which is the realistic ceiling for SBA-financed deals.

Do I need a broker to sell my business?

You do not need a broker, though brokers can help market your business to a wider pool of buyers. One important note: working with a Regalis-backed buyer costs you nothing as a seller. No fees, no commissions, no obligations. You get a serious, pre-qualified buyer with structured financing already in place, which means less time on deals that fall apart before closing.

What kills most business sales before they close?

The most common deal-killers: unexplained discrepancies between tax returns and P&Ls, heavy customer concentration (one customer at more than 20 to 25% of revenue), a lease with insufficient time remaining, unsubstantiated SDE add-backs, and owner dependency the buyer cannot realistically resolve during a 90 to 180 day transition. Addressing these before listing gives you significantly more leverage at the table.

Ready to Connect With a Qualified Buyer?

Regalis Capital works with serious, pre-qualified buyers who use SBA 7(a) financing to acquire established businesses. Every buyer we represent has gone through our underwriting process before making an offer, which means sellers spend less time on tire-kickers and more time on deals that actually close.

There is no cost to you as the seller. No fees, no commissions, no obligation.
