I've analyzed over 4,125 real conversations with business owners and acquirers. That experience taught me this: most people aren't building a business that can survive the sale. This guide exists to change that.
What No One Prepares You For After You Buy a Business
This isn't about due diligence. This is about what happens after the wire clears and the seller disappears. Most new owners aren't celebrating, they're quietly trying to figure out what they just bought, why their margin's disappearing, and whether they're now trapped inside someone else's mess.
What Buyers Wish They Knew
Margin Surprises
"The margins were off — we didn't catch it in time"
Seller Disappearance
"The seller ghosted me after two weeks. No documentation. No support"
Team Confusion
"I didn't know what my team actually did until people started quitting"
Missing Systems
"Everyone said the ops were simple. Turns out, the seller was the glue"
The 7 Post-Close Surprises That Kill Momentum
The seller was the system
SOPs are either nonexistent or ceremonial. Nobody follows them. When the seller leaves, institutional memory goes with them.
Margins lie under pressure
On paper, SDE looked clean. Post-close, you learn what was really classified as COGS, how aggressive the add-backs were.
The team doesn't trust you yet
They're cautious. Some are scared. If the previous owner was respected or loved, you've inherited a loyalty gap.
Your calendar is a war zone
You thought you'd be optimizing. You're reacting. Instead of building systems, you're putting out fires.
