Selling a business checklist
Selling a company has a lot of moving parts. The deals that go smoothly are almost always the ones where the seller did the work up front. Here's the whole thing, phase by phase, so you can see what's coming and tick off each step as you go.
Treat this as a working checklist, not light reading. Most of it happens in order, though the early phases tend to overlap. The single best move you can make is to start the cleanup work months before you actually want to sell. Buyers pay up for preparation. Surprises cost you.
PHASE 1 Before you list
This is the phase that quietly decides your price. The goal is simple: walk into the market with clean numbers and a clear head.
- Clean up your financials. Get three years of accurate statements and tax returns that tie out. If your bookkeeping is loose, fix it now. Buyers trust businesses whose numbers reconcile.
- Identify your add-backs. List the personal and one-time expenses that a new owner wouldn't carry, such as an owner's above-market salary, a personal vehicle, or a one-off legal cost. Document each one so it survives scrutiny.
- Get a realistic valuation. Know what your business is actually worth before you set expectations. Start with our business valuation calculator for a range, then get it reviewed.
- Decide what you actually want. A full exit, a partial sale, staying on for a transition period? Your goals shape which buyers fit and what deal structure makes sense.
- Reduce owner dependence. If the business can't run without you for a week, that's a risk buyers pay less for. Delegate, document processes, and build a bench.
- Pick your advisor. Choose an M&A advisor or broker who closes deals in your industry and your size range. The right one earns their fee in the price and the certainty of closing.
PHASE 2 Going to market
Now you package the business and get it in front of qualified buyers. The trick is doing that without tipping off staff, customers, or competitors.
- Build the teaser and CIM. The teaser is a short, anonymous summary that sparks interest. The confidential information memorandum (CIM) is the full story, including financials, that goes to serious buyers after they sign an NDA.
- Lock down confidentiality. Every interested party signs a non-disclosure agreement before they see anything identifying. Confidentiality protects your team, your customers, and your leverage.
- Build a qualified buyer list. Strategic buyers, private equity, search funds, and individuals all behave differently. Your advisor casts a wide enough net to create competition without leaking.
- Run a real outreach process. Reaching multiple buyers at once, rather than one at a time, is what creates tension and protects your price. A quiet auction beats a single conversation.
- Screen buyers for fit and funding. Make sure interested parties can actually pay and are serious before you invest time in management meetings and data sharing.
PHASE 3 Offers and due diligence
Offers come in, you pick one, and then the buyer pressure-tests everything you told them. Good prep here is what keeps the deal from slipping.
- Compare offers on more than price. Structure matters. Look at how much is cash at close, what's tied to an earnout, what's a seller note, and what the buyer expects from you afterward.
- Negotiate and sign the LOI. The letter of intent sets price, structure, and timeline, and usually grants the buyer a period of exclusivity. Get the terms right here because they frame the final contract.
- Build your document room early. Diligence requests are long: contracts, leases, customer and supplier details, employee records, insurance, litigation history. Having it organized before requests arrive keeps momentum.
- Prepare your team and answers. Buyers ask the same hard questions in different ways. Anticipate the issues, such as customer concentration or a key employee, and have honest, prepared answers.
- Keep running the business. A common deal-killer is performance slipping during diligence. The numbers you sold on need to hold up while the buyer is watching.
PHASE 4 Closing and transition
The final stretch turns an agreed deal into a completed one, and sets up the handover.
- Negotiate the purchase agreement. This is the binding contract. Pay close attention to representations and warranties, indemnification, and what happens if something turns up after close. Use experienced M&A counsel.
- Settle the deal structure. Asset sale or stock sale, how working capital is handled, and any holdbacks or escrow all affect what you actually walk away with after taxes.
- Pin down earnouts and seller financing. If part of your proceeds depends on future performance, define the targets and the math precisely. Vague earnouts breed disputes.
- Plan the transition. Agree on how long you'll stay, how customers and employees are told, and how knowledge gets transferred. A clean handover protects any deferred payment you're owed.
- Close and handle the after. Sign, fund, transfer, and then manage the tax, legal, and personal pieces that come once the money lands.
Where most of the value is won or lost
If you take one thing from this list, make it the first phase. What a buyer will pay, and whether the deal closes at all, is largely set before you ever talk to one. Clean books, documented add-backs, less reliance on you, a valuation you can defend: those do more for your outcome than any negotiation tactic later.

Common questions about selling a business
How long does it take to sell a business?
For most small and lower-middle-market businesses, plan on several months to roughly a year. The variables are how clean your financials are, how the business is priced, and how active buyers are in your sector. Preparation is the part you control, and it's what shortens diligence once an offer lands.
What documents do I need to sell my business?
At a minimum: three years of financial statements and tax returns, a list of add-backs, customer and contract details, your lease, an equipment and asset list, and an org chart. Buyers request far more in diligence, so building a document room early saves you a scramble.
Do I need a broker or M&A advisor?
You can sell on your own, but an advisor who knows your industry runs a confidential, competitive process, reaches buyers you wouldn't find, and manages diligence and negotiation. That usually shows up in both the price and the odds of actually closing. Get matched with a vetted firm, including no-retainer options, free to sellers.
What is a letter of intent (LOI)?
It's the buyer's written offer laying out proposed price, structure, key terms, and timeline before formal diligence. It's mostly non-binding except for clauses like exclusivity and confidentiality, but it frames the final purchase agreement, so the terms in it carry weight.
