Working with the seller after you buy their business

For a while after closing, the person who built the company is usually still around. They know every customer, every quirk of the equipment and every reason things are done the way they are. They're also adjusting to no longer being in charge of something that may have been the center of their life for decades.

Handled well, those months are the most valuable part of the purchase. Handled badly, they're awkward for everyone, including the employees watching. Here's how to make them work.

What the agreement says, and what it doesn't

The seller's role after closing is usually written into the purchase documents: how long they'll help, roughly how many hours, what they'll focus on and how they'll be paid. Our post on earnouts, holdbacks and transition agreements explains how those terms are set.

If you're buying the whole company with an SBA loan, the SBA's rules shape this. Its current lending rulebook, SOP 50 10 8.1, applies to loans given an SBA loan number on or after October 1, 2026. It says the seller can't stay on as an owner, officer or employee. If the business needs their help, it can hire them as a consultant for up to 24 months in total, including any extensions. Loans numbered before that date follow the earlier limit of 12 months. These rules change from time to time, so confirm the current limits with your lender before you agree on anything.

What no agreement captures is how you'll actually work together day to day. So in the first week, sit down with the seller and talk it through:

• What will they be doing, and what won't they be doing anymore?
• Which decisions are now yours alone?
• How will you handle it when employees or customers still come to them?
• How often will you two meet, and when?

Write down what you decide. It doesn't replace the formal agreement; it's a shared reference for when memories differ later.

Make a list of what lives in their head

Most of what a long-time owner knows isn't written anywhere. Before the transition starts, make a list together of everything you need to learn, and work through it every week. It usually includes:

• Customers: history, preferences, who to call, who's slow to pay and why.
• Pricing and bidding: how they price a job, when they discount, which work they turn down.
• Suppliers: terms, contacts, who will extend credit and who to call in a shortage.
• Equipment and systems: what breaks, who fixes it, what's due for replacement.
• The calendar: seasonal peaks, annual renewals, inspections, insurance dates.
• Outside relationships: the banker, the accountant, the insurance agent, local inspectors and permit offices.
• Licenses: if the company works under a license the seller holds personally, you should have settled on a plan for it before closing. Our post on licenses when you buy a business explains why, and the transition is when you carry that plan out.

A good way to learn each item is in three steps: first you watch the seller do it, then you do it while they watch, then you do it alone and tell them how it went.

Use their relationships on purpose

Introductions are the one thing the seller can give you that you can't get anywhere else, and the chance ends when the transition does. Plan them:

• Customers, starting with the biggest. Our post on keeping customers through a change of owner covers how to sequence them.
• Key employees, if they still look to the seller for reassurance. See keeping the team after you buy.
• Suppliers, referral sources and the people at the bank. A call from the seller saying "this is the new owner, treat them as you treated me" can save you months.

Boundaries that protect both of you

The hardest part of a transition is usually not knowledge but authority. Employees will keep going to the person they've gone to for years. Customers will keep calling the number they know. The seller, out of habit and care, will keep answering.

A few ground rules help:

• You make the decisions. The seller advises; you decide. Agree on this explicitly, and ask the seller to say it to the team.
• Redirect, gently. When an employee brings the seller a question, the seller's best answer is "Ask [your name], and I'll help if they need me." Have them start doing this in the first week.
• Disagree in private. If you and the seller see something differently, talk about it away from staff and customers. Never overrule each other in front of the team.
• Respect what they built. Changing something they did for twenty years isn't a criticism of them, but it can feel like one. Ask what they think first, then explain your reasons. Sometimes they'll tell you why it was done that way, and sometimes that will change your mind.

Purchase agreements often include the seller's promise not to compete with the company or recruit its employees and customers for some years. In Florida, a court will enforce such a promise only if it's in writing and signed by the seller. In a business sale, the law presumes that a restriction lasting three years or less is reasonable in length and one lasting more than seven years is not (Florida Statutes section 542.335). Your attorney should draft it, and it belongs in the closing documents, not in a conversation.

Keep your side of the bargain

The relationship with the seller doesn't end with the transition. If part of the price is a seller-financed note, the seller is also your lender, often for years. Keep to the note's terms exactly, tell them early if anything is wrong and honor everything you promised about the company, especially what you said about the employees and the name. Sellers talk to other owners, and how you treat this one will follow you.

How the seller is paid for their help during the transition is a question for your attorney and accountant, and with an SBA loan it has to fit the consultant arrangement described above. Get it right from the start.

When to take the wheel

You'll know the transition is nearly done when:

• customers call you first, not the seller;
• employees bring problems to you without being redirected;
• you can price a job, handle a complaint and solve a staffing gap on your own;
• you've been through at least one busy stretch without needing the seller in the room.

It helps to scale back the seller's time gradually: from full days, to a few days a week, to being available by phone. Set an end date you both know about, and mark it. A thank-you lunch with the team, or a short note to customers from the seller, lets everyone see the handover is finished and that it ended well.

Some sellers will want to leave sooner than planned, and some will find it hard to leave at all. Either is understandable. Talk about it openly and adjust within what your agreement allows. If you need to change the agreement itself, involve your attorney and, with an SBA loan, your lender, since the SBA's time limit counts any extensions.

If it isn't working

Sometimes a transition goes wrong: the seller isn't showing up, is undermining you, or can't let go. Raise it early, privately and specifically: "When customers call you directly, I'd like you to send them to me." Problems like these are often habits, not bad intentions, and a frank conversation can fix them.

If talking doesn't fix it, read your agreement again with your attorney before you do anything else. Whatever happens, keep the disagreement away from employees and customers. They should see two people handing over a company with respect, because that's what keeps them confident in the business you now own.
