The Direct Answer
You use a 100-day plan when selling a business to prove success by handing the new owner — private equity, strategic buyer, or private buyer — a written transition document that maps the first 90 to 100 days after close. The document covers the initiatives already in motion, the resources and subcontractors in play, the contacts the buyer will need, and the thesis behind each plan. The 100-day plan is a goodwill instrument that reduces owner dependency at handoff, supports your earn-out and hold-back terms, and proves you sold a real company rather than walked away from a check. The buyer may use parts of it, all of it, or none of it. Either way, the gesture signals seller integrity and helps the deal close at maximum multiple. You build this in the months before sale and present it at the closing table.

Why The 100-Day Plan Matters For The Buyer
Buyers walk into the first 100 days after acquisition with hopes, dreams, and aspirations — and almost always with less information than they need. They have read the CIM. They have done diligence. They have met the management team. None of that is the same as actually operating the business. The 100-day plan closes that gap. It tells the buyer what was in motion, what was working, what was about to be tested, and what resources were lined up to support each initiative.
The buyer reading a thoughtful 100-day plan immediately knows two things. First, the seller cared about the outcome after the close, not just the wire transfer. Second, the business has documented continuity — operations were not improvised, they were planned. Both signals support the transition and reduce the buyer’s tendency to second-guess the price. The EXIT framework covers the broader transaction execution discipline that the 100-day plan slots into.
How The 100-Day Plan Reduces Owner Dependency
Owner dependency does not end at the closing table. It ends when the buyer can operate the business without calling the seller every other day. The 100-day plan accelerates that handoff by writing down the things the seller would otherwise hold in their head. Without the plan, the buyer calls the seller at week three asking who the vendor is for X, what the thesis was behind Y, why initiative Z was paused. With the plan, the buyer reads the answer and keeps moving.
The math is real. Sellers who hand off well typically exit faster from earn-out periods and hold-back arrangements. Sellers who fight the documentation get pulled back in for 6, 12, or 18 months of unstructured advisory time that was never supposed to be part of the deal.

What Goes Inside The 100-Day Plan
The plan covers seven categories that together describe the operating reality of the business going forward. First, initiatives already in motion — projects started, half-finished, or planned, with current status. Second, the thesis behind each initiative — what the seller was trying to accomplish and why. Third, key contacts — customers, vendors, advisors, attorneys, lenders, and anyone the buyer will need to reach. Fourth, resources and tools — subscriptions, systems, login credentials structures, and operational tooling.
Fifth, subcontractors and outside service providers — names, scope, rates, and quality assessment. Sixth, success metrics — what the seller was using to track each plan and what numbers looked good versus bad. Seventh, escalation triggers — when something is going wrong, who the buyer should call and what the warning signs look like. These seven categories cover the operational reality the buyer needs to absorb in the first 90 to 100 days.
The Playbook Mindset Versus The Walk-Away Mindset
There are two ways to exit a business at closing. The playbook approach hands the buyer the operating manual the seller was using. The walk-away approach hands the buyer a wire confirmation and silence. The two approaches produce different outcomes for both sides.
The playbook approach signals seller integrity and intention. It costs the seller 20 to 40 hours of work in the months before close. It produces goodwill that compounds during the transition window — particularly for earn-out and hold-back resolution. The walk-away approach saves the seller those hours but creates friction that lasts months. Buyers remember which approach the seller took, and that memory affects every interaction during the post-close window. The SELL framework covers how seller integrity at handoff affects the final terms of the deal.
Why The 100-Day Plan Supports Your Earn-Out And Hold-Back
Most mid-market deals include some form of contingent consideration — earn-outs tied to post-close performance, hold-backs against indemnification claims, or seller financing with performance triggers. The 100-day plan affects every one of those mechanisms. A buyer who feels well-equipped post-close hits earn-out targets faster, releases hold-backs more readily, and disputes fewer claims. A buyer who feels abandoned post-close finds reasons to delay, dispute, and hold back funds.
The relationship is structural. Goodwill at handoff translates directly to faster resolution of contingent payments. The 20 to 40 hours invested in building the 100-day plan often returns hundreds of thousands or millions in faster earn-out releases. The Foundational Four documents are the raw material that populates the 100-day plan — SOPs, job descriptions, decision bands, and the org chart all feed into what the buyer needs.
The Buyer May Use Nothing — That Is Fine
The buyer reading the 100-day plan has three choices. Use all of it. Use parts of it. Use none of it. The seller does not control which choice the buyer makes. The seller only controls whether the plan exists and whether it was honestly built.
If the buyer uses none of it, the seller still wins. The act of producing the document signaled professionalism and intent. The buyer cannot unsee the effort. Even when the new owner takes the business in a completely different direction, the goodwill from the handoff persists. Earn-outs still release. Hold-backs still come back. Reference calls still go well. The downside of producing a thoughtful 100-day plan is zero. The downside of not producing one is meaningful. Always build it.
When To Start Building The 100-Day Plan
The 100-day plan should be drafted in the 90 to 120 days before close — not the night before. The draft starts taking shape as soon as the LOI signs and diligence begins. The seller has visibility into the buyer’s profile, the structure of the deal, and the kinds of questions the buyer is asking. All of that information shapes what belongs in the plan and what level of detail matters.
The draft gets refined through the diligence window. The seller learns what the buyer cares about, what they understand, and where they have gaps. The final version is ready at the closing table or shortly after. Sellers who try to build the plan after close are usually too late — the buyer is already calling with questions the plan should have answered. Build it during the diligence window, present it at close, and watch the post-close transition go smoother than it would have otherwise.
Frequently Asked Questions
What is a 100-day plan when selling a business?
A 100-day plan when selling a business is a written transition document the seller hands the buyer at or near close that maps the first 90 to 100 days of operations. It covers initiatives in motion, key contacts, resources, subcontractors, success metrics, and escalation triggers. The plan reduces owner dependency at handoff and supports the buyer’s ability to operate the business immediately after acquisition.
Who builds the 100-day plan — buyer or seller?
The seller builds the 100-day plan as a transition document for the buyer. The buyer may have their own internal 100-day plan for integration, but the seller’s plan is the operational handoff — what was happening, why, who was involved, and what comes next. Both plans can coexist and complement each other.
How does a 100-day plan affect my exit multiple?
A 100-day plan does not directly raise the multiple, but it indirectly protects the multiple by reducing perceived transition risk during diligence. Buyers who see a thoughtful plan during diligence have higher confidence in the transferability of operations. The plan also accelerates earn-out releases and hold-back resolutions, which preserves the realized value of the multiple after close.
What should I include in a 100-day plan?
Include seven categories — initiatives in motion with current status, the thesis behind each initiative, key contacts (customers, vendors, advisors, attorneys, lenders), resources and tools, subcontractors and outside providers, success metrics for each plan, and escalation triggers with named contacts. These categories cover the operational reality the buyer needs to absorb in the first 90 to 100 days.
When should I start writing the 100-day plan?
Start the draft when the LOI signs and diligence begins, about 90 to 120 days before close. The diligence window gives you visibility into the buyer’s profile and concerns, which shapes the plan’s content and detail level. The final version should be ready at the closing table. Sellers who start writing after close are usually too late.
Does the buyer have to use the 100-day plan?
No. The buyer may use all of it, parts of it, or none of it. The seller does not control which choice the buyer makes. The seller only controls whether the plan exists and whether it was honestly built. Even when the buyer uses none of it, the goodwill from producing the document persists through the post-close window.
How does the 100-day plan help with earn-out releases?
Earn-out releases require the buyer to verify that performance targets were hit. Buyers who feel well-equipped post-close hit those targets faster, dispute fewer claims, and release contingent payments more readily. The 100-day plan reduces the friction that delays earn-out resolution. The 20 to 40 hours invested often returns hundreds of thousands in faster releases.
Should I share the 100-day plan during diligence or only at close?
Sharing during diligence — typically after the LOI signs — is usually the right call. Showing the draft signals seller professionalism and gives the buyer comfort about operational continuity. The final polished version is presented at or near close. Some sellers wait until close to share, but earlier sharing typically supports the deal better than withholding.
How long should the 100-day plan be?
Most 100-day plans for mid-market businesses run 20 to 50 pages depending on complexity. Smaller businesses with fewer initiatives may need 10 to 15 pages. Larger businesses with multiple divisions may need 75 to 100 pages. The page count matters less than the operational completeness — every initiative, contact, resource, and metric the buyer needs to know should be in there.
What is the difference between a 100-day plan and a transition services agreement?
A transition services agreement (TSA) is a legal contract that defines specific services the seller will provide post-close for a defined period — typically operational support, IT services, or accounting services. A 100-day plan is a goodwill document that describes operations and helps the buyer navigate. The TSA is contractual. The 100-day plan is informational. Most deals use both.

When somebody buys your business, they have hopes, dreams, and aspirations that things are going to go well. So how do you use a 100-day plan to show the buyer you have already thought through their problems before they make the purchase? How can it help you? And why does this matter? This is a fantastic question. I am Scott Sylvan Bell, coming to you live from Bora Bora, on a perfect day to talk about business growth, business execution, business sales, and a fantastic day to talk about you.
I am coming to you live from the beach. So let us say that next month your company is up for sale, and you are going to have transferability, and you have done all the work. One of the coolest things that you could do is prepare the new owner for what initiatives you were working on, and give them the roadmap and give them the updates and say — hey, listen, if it was me, here is my one quarter plan, or my 100-day plan, that would help you out in this transition.
What this does is it helps reduce some, if not all, of your owner dependency, and allows for you to sit on the beach instead of having to be chained to a desk in an office and answer questions. You are literally taking your momentum that you already had prior to the sell and you are saying — here is what you are going to have to do to keep that process going alive. Here is what you are going to have to do for you to get the best lift, for you to get the best actions from the team.
The teams are not going to know what needs to be done, you are just leaving the playbook for them. So if at all possible, whatever definitions that you can leave are really going to benefit you — people to contact, resources that you use, subcontractors that you use, ways that you define the plan for success, the thesis for success for each plan.
What that does is it gives the new owner visibility on what was going on. Now they may look at it and go — we are never going to use that stuff. But they may look at it and say — hey, that is freaking cool, and we are glad that you took some time on the way out to prepare us for what you had going on, and the opportunities that are still available.
For them, anytime that they can prove that they bought a good company going into the purchase, it is goodwill. It is a way for you to say — I have got some information for you, and I want to help you with this transition, and I want to help you make it as smooth as possible. Versus peace out, Girl Scout, we are done, we are not going to give you any information, and we have got no clues for you.
The first way is way cleaner. It gives the old team a chance to win and show that they got skills, talents, and capabilities. And it proves that you have a good company that you wanted to sell — that you were not just trying to get some money and walk away from a deal.
So I would create a transition document that outlines the next 90 to 100 days after the sale is made, so that whatever team has bought you — private equity, strategic buyer, or whatnot — has the capability of winning and is happy with the deal. It does help when it comes to your hold-backs or earn-outs and all the other legal necessities, because you built some goodwill and said — hey, listen, I tried to help.
There you go. Start thinking about how you can help with the execution once the sale is made. Once again, they may say we want no part of it, but at least you said — I have got the next 90 to 100 days lined out for you to make as easy as possible.
