The First 100 Days After Acquiring a Business

Closing day is the starting line

Most of the attention in an acquisition goes to the months before closing: valuation, diligence, financing, the purchase agreement. Then the wire clears, everyone shakes hands, and the actual work begins. The first hundred days after closing decide whether the business you bought keeps the people, customers and momentum that made it worth buying.

This is the plan we think about when Tage acquires a business. It is written for buyers of small and mid-sized private companies, where the founder is often still involved, the team is lean, and a few key relationships carry a lot of the value.

Before day one: the plan you write during diligence

The best 100-day plans are drafted before closing, while diligence is fresh.

• List the value drivers. Which customers, people, licenses, suppliers and systems would hurt most to lose? These get attention first.
• Name the risks you accepted. Every deal has open items. Write down the ones you chose to live with and who owns each.
• Agree on the seller's role. How many hours, for how long, doing what? Put it in a transition services or consulting agreement, not a handshake.
• Draft the announcement. Decide who hears first, in what order, and from whom.

Days 1–30: listen, stabilize, communicate

Tell people early and in person

Employees will hear about the sale one way or another. It is far better that they hear it from the seller and the new owner together, on day one or as close to it as possible. Say what is changing, what is not, and when they will hear more. Uncertainty is what drives good people to start answering recruiter calls.

Within the first two weeks, meet one-on-one with every key employee. Ask what they would fix, what worries them, and what they are proud of. You will learn more about the business in those conversations than in the data room.

Call the top customers yourself

Alongside the seller, contact the customers that make up the largest share of revenue. The message is simple: same team, same service, and here is who to call if anything changes. Concentration risk you identified during diligence is most real in this window; we wrote about it in customer concentration risk before an exit.

Protect cash and controls

Ownership changes are a window for mistakes and, occasionally, fraud. In the first weeks:

• Update bank signatories and payment approval limits.
• Confirm payroll, benefits and insurance carried over correctly, including any new entity or policy names.
• Review accounts receivable and collections; a sale is a common moment for slow payers to get slower.
• Make sure licenses, permits and key vendor accounts are in the new owner's name where required.

Change as little as possible on purpose

Resist the urge to rebrand, reorganize or replace software in month one. Early changes should fix real risks, not express the new owner's preferences. Every change you make before you understand the business is a guess.

Days 31–60: learn the business from the inside

Build the operating rhythm

Set a simple, regular cadence: a weekly leadership check-in, a monthly look at financial results against plan, and a short scorecard of the five to ten numbers that actually tell you how the business is doing. Choose metrics the team already understands before adding new ones.

Map how work really gets done

Shadow the processes that drive revenue and cost: quoting, scheduling, billing, hiring. Write down where the seller is still the only person who knows how something works. Each of those is a handoff item for the transition agreement.

Make the first visible improvements

By now you should have a short list of problems the team has been asking someone to fix for years: a broken tool, an unclear approval process, a missing hire. Fixing one or two of these early earns more trust than any speech about the future.

Days 61–100: set the direction

Agree on priorities for the next year

With the team, settle on a small number of priorities, typically three to five, each with an owner and a measurable result. Tage uses this kind of cadence across its portfolio companies so that leadership and the parent company are looking at the same scoreboard.

Decide what to integrate

If you own other businesses, this is the stage to decide which back-office functions to share: payroll, HR, IT, legal templates, marketing tools. Shared services should make the operating team's week easier. If a change only makes reporting tidier for the parent, it can wait. More on this balance in what a holding company actually does for the businesses it owns.

Complete the founder handoff

By day 100, the seller's remaining responsibilities should be clear, written and time-bound. Plan the moment the seller steps back, and recognize their role publicly. Customers and employees take their cue from how that exit is handled.

Common mistakes

• Announcing big changes before learning the business. It signals that the new owner did not value what was built.
• Letting the seller disappear too early, or stay too long. Both create confusion about who is in charge.
• Ignoring the second layer of the team. Supervisors and senior individual contributors often hold the operational knowledge and the customer relationships.
• Underfunding working capital. A closing balance sheet that looks fine can still leave the business short in its first slow month.
• Treating the 100-day plan as a document instead of a habit. Review it weekly and change it when you learn something.
