AI after an acquisition: a 90-day plan for small businesses
Most writing about AI in M&A is about big companies merging their IT. A small business you just bought has a different problem: an owner who did a lot by hand has left, staff are nervous, and every dollar of profit matters for your loan payments. The goal is not to "transform" the business. It is to protect what you bought, then take out the busywork.
Days 1–30: change nothing, measure everything
The first month is for learning. Write down how the business really runs, then put a number on each of these:
| Measure | How to get it | Why it matters |
|---|---|---|
| Calls missed per week | Phone system log, or count for one week | A missed call in a service business is often a lost job |
| Days to get paid | Invoice date to payment date, last 3 months | Cash you are waiting for is cash you cannot use for the loan |
| Hours a week on quotes | Ask whoever writes them | Slow quotes lose work to faster competitors |
| Days to close the month | When do you see last month's P&L? | You cannot manage what you see six weeks late |
These four numbers are your "before." Without them, you will never know what the AI actually did.
Days 31–60: the first two automations
1. Phone answering and booking
An AI receptionist answers every call, books jobs into the calendar, and texts the customer a confirmation. Start with after-hours and overflow calls only, so the team still answers during the day. Measure: calls missed, jobs booked.
2. Invoicing and collections
Invoices go out the day the job is done, with a payment link, and reminders go out on their own. Measure: days to get paid.
Do one, wait two weeks, check the number, then do the next. Two changes at once means you cannot tell which one worked, or which one broke something.
Days 61–90: quotes and monthly numbers
3. Quotes and quote follow-up
AI drafts the quote from the job notes and price list. A person still checks and sends it. Unanswered quotes get a follow-up after a few days.
4. Monthly reporting
The books are reconciled and a one-page P&L arrives in the first days of each month. For a buyer with a loan, this is the most important one: you see a problem in week one, not week six.
What not to automate yet
- The people customers know. The relationships are often what you paid for.
- Everything at once. One change at a time, with a number before and after.
- Anything the staff were not told about. Tell them what is changing and why, before it changes. Say plainly whether jobs are affected.
In a roll-up: build it once, copy it everywhere
If you plan to buy several businesses in one industry, this is where AI pays most. Build the setup in the first business. Write down how each piece works. Then every business you add starts from a tested setup, in weeks instead of months. The combined company also gets one set of numbers, in one format, every month, which is what lenders and later buyers ask to see.
Check how the deal is financed before you plan the work: the loan payments set how much room you have. Our free roll-up calculator shows the debt service and coverage for each business you add.
Questions people ask
What should I automate first after buying a small business?
Phone answering and booking, invoicing and collections, quotes, and monthly reporting. They repeat every day, they are easy to measure, and customers barely notice the change.
How soon after closing should I add AI?
About 30 days after closing. Use the first month to learn the business and record your "before" numbers.
Will AI replace the staff I just inherited?
In the first 90 days, it should take busywork off them, not replace them. The people who know the customers are part of what you bought.
How does AI work in a roll-up?
Build it once in the first business, write it down, and copy it into each business you add.
