Post-close · 4 min read · Breakthru Ventures

Closing day feels like the finish line. It is actually the start of the hardest part. In the first few months, employees, customers and suppliers are deciding whether to trust the new owner, and the business is at its most vulnerable to disruption. A clear plan for the first 100 days helps you protect the value you just paid for and set up the improvements that justify the investment.

The guiding principle is simple: stabilize first, improve second.

Before closing: build the plan

The 100-day plan should be drafted during diligence, not after. Use what you learned to answer a few questions:

• Who are the people the business cannot afford to lose?
• Which customers and suppliers account for the largest share of revenue and supply?
• What does the seller do day to day, and who will do it after the transition?
• What systems, licenses, permits, bank accounts and insurance policies need to change hands?
• What are the two or three biggest risks you found in diligence?

Agree on the transition terms with the seller in writing, including how long they will stay, what they will do and how they will introduce you to key relationships.

Days 1 to 30: stabilize and listen

The first month is about continuity and trust.

Communicate early and clearly. Meet employees on day one, ideally together with the seller. Explain who you are, why you bought the business and what will and will not change in the near term. Uncertainty breeds rumors; say plainly that payroll, benefits and day-to-day roles continue as they are while you learn.

Meet key customers and suppliers. With the seller, contact the most important relationships personally. Reassure them that service will continue and give them a direct way to reach you.

Secure the basics. Confirm control of bank accounts, payroll, insurance, licenses, domain names, software accounts and passwords. Set up the reporting your lender requires. Make sure you can see cash daily.

Listen more than you talk. Spend time with each team member. Ask what works, what frustrates them and what they would change. Write down what you hear. Resist the urge to fix things you do not yet fully understand.

Avoid big changes. Unless there is a safety, legal or cash emergency, postpone changes to pricing, people, systems and branding. Early changes made without context are a common source of employee and customer departures.

Days 31 to 60: learn the business

In the second month, move from relationships to how the business actually runs.

• Map the core processes. How does work come in, get priced, get delivered and get billed? Where are the bottlenecks and handoffs?
• Understand the numbers. Build a simple weekly dashboard with a handful of measures that matter: cash, sales or bookings, backlog, gross margin, receivables and any key operating metric for your industry.
• Identify key-person risk. Note where knowledge lives in one person’s head and start documenting it.
• Review contracts and pricing. Look for customers below current pricing, expiring agreements and supplier terms worth revisiting later.
• Test your diligence assumptions. Compare what you see to the model you used to buy the business, and update your plan where reality differs.

By the end of this period, you should be able to run the business without calling the seller for routine questions.

Days 61 to 100: set priorities and start improving

With a stable base and real understanding, you can begin making deliberate changes.

Pick a small number of priorities. Choose two or three improvements with clear value and manageable risk. Common early candidates include tightening invoicing and collections, adjusting pricing on unprofitable work, improving scheduling or fixing a recurring service problem.

Share the plan. Tell your team what the priorities are and why. Involve the people who raised the problems during your listening period; it shows you heard them.

Make people decisions carefully. If roles need to change, make the decision with facts gathered over several months, and handle it respectfully. How you treat people in the first changes sets the tone for your ownership.

Set a cadence. Establish regular team meetings, a monthly financial review and a quarterly planning rhythm. Routine reduces the number of urgent surprises.

Plan the next year. Turn what you have learned into a 12-month plan with targets, budget and responsibilities.

Common mistakes to avoid

• Changing too much too quickly.
• Spending all your time on financials and too little with people.
• Letting the seller leave before key relationships have transferred.
• Ignoring cash. Seasonal swings, working capital needs and loan payments can surprise a new owner.
• Trying to do everything yourself instead of building a team you can rely on.

Bottom line

The first 100 days decide whether the business you bought keeps the strengths you paid for. Protect relationships and cash first, learn how the business really works, then improve it deliberately with your team on board.
