The short answer: in your first 90 days, do not change much. The fastest way to break a business you just bought is to "fix" it before you understand it. Keep the key people, learn the cash cycle, meet the top customers and vendors, and use the seller's transition period to absorb everything in their head. Earn trust first; make changes second.
Resist the urge to change everything
You bought the business because it works. Day one is the worst possible time to redesign it. Staff are nervous, customers are watching, and you do not yet know why things are done the way they are. Spend the first weeks listening, not reorganizing. Most of what looks inefficient from the outside exists for a reason you have not learned yet.
Keep the people who make it run
The biggest risk right after closing is that key employees walk. They hold the customer relationships, the tribal knowledge, and the daily operations. Meet them early, tell them their jobs are safe, and ask what they would improve. In many small businesses the value you paid for lives in a handful of people, keeping them is job number one.
Watch the cash, not just the profit
Profit on paper is not money in the bank. Learn the cash cycle fast: when customers pay, when suppliers and payroll are due, and how much working capital the business needs to breathe. A profitable business can still stall if you run the account dry in month two.
Meet the customers who matter
Identify the top accounts and introduce yourself, ideally alongside the seller. Reassure them nothing they value is changing. This does two things: it protects the revenue you just financed, and it surfaces the real reasons customers stay, which is the foundation for any growth you attempt later.
Use the transition period fully
The seller's training window is a wasting asset. Every day they are still around is a chance to pull knowledge out of their head: vendor quirks, seasonal patterns, the informal fixes that never made it into a manual. Write it all down. Once the transition ends, that knowledge is gone unless you captured it.
A simple 90-day arc
- Days 1 to 30: introduce yourself, keep everything running, learn the cash cycle, capture the seller's knowledge.
- Days 31 to 60: understand the numbers deeply, meet vendors, find the small frictions worth fixing later.
- Days 61 to 90: make your first careful, well-communicated improvements, the low-risk ones with obvious upside.
Plan the handoff before you close
The best first 90 days are designed during diligence, not improvised after.

Frequently asked questions
As little as possible. Spend the first weeks learning why things work the way they do, keeping key people, and understanding the cash cycle. Make your first changes around day 60 to 90, starting with low-risk improvements that are easy to communicate.
Meet them early, reassure them their jobs are safe, listen to what they would improve, and avoid sudden changes. In most small businesses, the key relationships and knowledge live with a few people, so retaining them is the top priority.
Profit on paper is not cash in the account. If you do not understand when customers pay and when payroll and suppliers are due, a profitable business can still run short on cash. Learn the working-capital rhythm in your first month.
