The First 100 Days After Buying a Small Business: A Field Guide for New Owners
The closing is not the finish line. For a new owner, the first 100 days decide whether the business you bought is the business you keep. Employees are watching for signs of what will change. Customers are wondering whether the person they trusted is leaving. Suppliers are checking whether the new owner pays on time. And your lender wants its first report.
This is the plan we use, adapted for a business with a few million dollars of revenue and a small team.
Before day one: the week before closing
- Write the announcement. Who tells employees, in what order, and when. Key employees should hear it before the all-staff meeting. Customers and suppliers should hear it from the seller and the new owner together.
- Line up bank access. New accounts, signers, payroll provider access, merchant processing and any loan sweep. Payroll on the first Friday after closing must not bounce.
- Get the keys to everything. Domain registrar, website host, email, accounting software, point of sale, e-commerce store, phone system, social media accounts, alarm codes. Make a list and confirm each one transfers.
- Agree the seller's role in writing. Hours, duration, what they handle, who they report to. Under current SBA rules a seller can consult for a limited period after closing; your lender will tell you how long.
Days 1 to 30: listen, protect cash, change almost nothing
The biggest mistake new owners make is changing too much too fast. The business worked well enough for you to buy it. In the first month, your job is to learn why.
People - Meet every employee one on one. Ask three questions: What should I not change? What drives you crazy? What would you fix if you were me? - Confirm pay, benefits and schedules stay the same for now. Uncertainty about paychecks is the fastest way to lose good people. - Identify the two or three people the business cannot run without. Spend extra time with them.
Customers - Call or visit your top 20 customers with the seller. Say thank you. Ask what they value and what could be better. - Do not raise prices in month one unless the deal plan requires it and you have warned customers.
Cash - Set up a weekly 13-week cash forecast. Receipts in, payroll and bills out, loan payments, ending balance. - Put two-person approval on payments above a set amount. - Review receivables weekly. Collections often slip during a transition because the person who used to call slow payers was the old owner.
Compliance - Confirm licenses, permits and registrations are in the new entity's name. For food businesses, that includes FDA food facility registration and any state food establishment permit. For dental and healthcare, provider credentialing with insurers. These can take weeks, so start before closing if you can.
Days 31 to 60: find the quick wins and the real risks
By now you know where the business leaks time and money. Pick a short list.
- Fix the monthly close. Books closed by the 10th of the following month, reconciled to the bank, with a one-page summary of revenue, gross margin, payroll and cash. If the business was on a once-a-year accountant cycle, this is the single most valuable change you can make.
- Map the top five processes. Quoting, ordering, scheduling, fulfillment, billing. Write each one down as it actually happens today, not as it should happen. You will find the rework.
- Price check. Compare your prices against what it costs you to deliver. In many owner-run businesses, prices have not been raised in years because the owner did not want the conversation. Plan a measured increase with notice, not a shock.
- Look at the tech stack. Most small businesses run on five or more disconnected tools and a lot of spreadsheets. Do not rip anything out yet, but list what you have, what it costs and where people re-type data. This list becomes your systems plan. Our article on practical AI for owner-run businesses covers where automation pays off first.
Days 61 to 100: commit to a plan
- Write a one-page plan for the rest of year one. Three to five priorities, each with an owner, a deadline and a number. For example: "Reduce order-to-ship time from five days to three by March," or "Bring receivables over 60 days below 10% of total."
- Fill or plan for the key-person gap. If the seller was doing sales, estimating or the books, decide who does that when the consulting period ends.
- Send the lender and investors a clean report. Monthly financials, covenant calculations, a short narrative on what is going well and what is not. Lenders forgive bad news far more readily than surprises.
- Hold a team meeting on the plan. Share what you heard in month one, what you are keeping, and what will change. Then do what you said.
What not to do
- Do not rebrand in the first 100 days. A name customers have known for decades is an asset. Frisco Brand Spices, for example, has been blending seasonings in Nebraska since 1928, and that history is part of why customers buy.
- Do not cut the person everyone calls "the one who knows where everything is."
- Do not launch a major software migration in month one. Stabilize first.
- Do not let the seller disappear early, and do not let them keep running the business either. Agree on the handoff and stick to it.
