The 5 Biggest Acquisition Mistakes I’ve Made (And How to Avoid Them)

In this post, I break down the five acquisition mistakes that cost me the most time and money: waiting too long to plan an exit, messy books, skipping due diligence, weak contracts, and scaling without systems. If you’re buying a route or planning to sell one, this is the playbook I wish I had earlier.

Key takeaways:

• Start exit prep 12+ months before selling
• Clean books raise multiples and reduce retrades
• Never skip due diligence, even for friends
• Contracts and concentration risk drive valuation
• Systems determine whether you’re selling a route or a real business

Over the last few years, we’ve completed close to 20 acquisitions, from small local routes to multi-million-dollar transactions.

And I’ll tell you something most people won’t:

I’ve made mistakes.

Not small ones. Expensive ones.

Acquisitions look clean on paper. In real life, they’re emotional, complicated, and full of risk. And if you don’t stay disciplined, you’ll pay a steep tuition to learn lessons the hard way.

Here are the five biggest acquisition mistakes I’ve made, and the stories behind them.

#1 Waiting Too Long to Think About the Exit

The first mistake doesn’t even happen during an acquisition.

It happens years before.

I’ve sat across the table from operators who built solid routes – good locations, good reputations – but never built a business that could run without them.

They were the technician.
The relationship manager.
The problem solver.

And when it came time to sell, the buyer wasn’t acquiring a company.

They were inheriting a job.

One seller told me, “I wish I started preparing five years ago. I didn’t realize how much I was in the business.”

If you think you might exit in 3–5 years, start today. Clean books. Strong contracts. Delegated operations.

Value isn’t created at closing.

It’s created long before it.

#2 Cleaning Up the Numbers Too Late

Early on, I underestimated how much presentation impacts valuation.

I remember reviewing a deal where the seller insisted his business was “more profitable than it looked.” When we dug into it, the P&L was full of personal expenses.

Car payments. Insurance. Travel. Family items.

Yes, those can be added back. But messy books create doubt.

And doubt reduces multiples.

Here’s the math most operators miss:

If your business sells for 3.5x EBITDA, every extra dollar of clean profit is worth $3.50 at exit.

Saving 30% in taxes today might cost you hundreds of thousands later.

When you know you’re going to sell, stop optimizing for tax minimization and start optimizing for valuation.

#3 Falling in Love With a Deal

This one stung.

There was an operator I had known for years. We had always talked about doing a deal one day. When he finally called and said he was ready, I wanted it badly.

We moved fast.

Too fast.

Because of the relationship, I softened some of the due diligence. I trusted verbal assurances. I assumed key locations were solid.

After closing, we discovered one of the largest merchants had already signaled they were exploring other options.

That wasn’t technically hidden from us, but we didn’t press hard enough.

The lesson was brutal but clear: When money gets involved, relationships change.

No matter how long you’ve known someone, due diligence is not optional.

If something feels unclear, slow down. Ask harder questions. Be willing to walk. The best deals are the ones that still make sense after uncomfortable conversations.

#4 Ignoring a Red Flag That Can Cost You Everything

Here’s a story I’ll never forget.

Years ago, we were the seller. We sold a large route to a national buyer. During due diligence, they flagged one supermarket chain that made up a significant percentage of revenue.

The issue? The contract had an early-out clause before renewal.

We knew the family that owned the chain. Great relationship. Years of history. I pushed back.

The buyer didn’t.

They were smart enough to insist on a protective clause tied specifically to that contract. If the chain canceled before closing, the deal economics would adjust.

We negotiated. We closed.

Three days before funds were released, we received a letter: the supermarket chain was canceling.

They had been offered a deal by a major bank that we couldn’t compete with. Not because of ATM economics, but because the bank wanted the customer relationship.

And because of the buyer’s protection clause?

We lost money.

If that clause hadn’t been there, the buyer would have been exposed.

But it was in there, and we were on the wrong side of it.

That experience permanently changed how I view:

• Contract structure
• Early termination language
• Revenue concentration
• And buyer protections

Contracts determine multiples.
Concentration determines risk.
Risk determines price.

And if you’re not paying attention, it determines who wins in the final hour.

#5 Scaling Without Systems

The final mistake is the most common. Buying growth without having the infrastructure to absorb it. I’ve seen operators double their size, and double their chaos.

No standardized contracts.
No operational playbook.
No reporting discipline.
No revenue optimization strategy.

That’s not scaling. That’s multiplying complexity.

At ATM UP, we eventually built internal systems to force discipline – from contract standards to revenue-per-location optimization.

Because here’s the truth:

If all you’re selling is machines, your buyer pool is limited to ATM operators.

If you’re selling systems, processes, and scalable growth, you attract a completely different class of buyer.

And that changes your multiple.

The Bigger Lesson

Every acquisition decision should be made with your future exit in mind.

If you wouldn’t accept a certain weakness when selling, don’t accept it when buying.

If you wouldn’t want to explain a decision to your future buyer, don’t make it today.

Acquisitions can accelerate growth.
They can also accelerate mistakes.

I’ve made mine.

If you’re acquiring, be disciplined.

If you’re planning to exit, start earlier than you think.

The operators who win in the long run are the ones who treat this like an enterprise, not just a route.

Frequently Asked Questions About Buying or Selling an ATM Route

What’s the biggest mistake operators make before selling an ATM business?

The biggest mistake operators make is waiting too long to prepare for their exit. Most owners build their business around themselves and only start thinking about selling when they’re ready to retire. By then, contracts may be weak, financials may be messy, and there may be no systems in place.

If you want the strongest valuation, you should begin preparing at least 12 months before you plan to sell. Clean up financials, strengthen contracts, reduce owner dependence, and document processes. Exit value is built years before the transaction, not during it.

What documents should I have ready before I sell my route?

Before selling an ATM route, you should have:

• Merchant contracts (signed and assignable)
• A clear list of machine locations
• Financial statements (preferably 2–3 years)
• A breakdown of revenue by location
• Expense details (with add-backs clearly identified)
• Machine age and equipment list
• Service and maintenance history
• Insurance documentation

The more organized and transparent your documentation, the smoother the due diligence process and the stronger your negotiating position.

Why do clean financials increase valuation?

Buyers value businesses based on profit, not revenue. Most acquisitions are priced using a multiple of EBITDA or gross net income.

When personal expenses are mixed into the business, it creates uncertainty. Even if those expenses can be “added back,” messy books reduce buyer confidence and increase perceived risk.

Lower risk = higher multiple.

If a buyer feels confident in your numbers, they are far less likely to retrade the deal or discount your valuation.

What contract terms matter most in an acquisition?

The quality of contracts directly impacts valuation. The most important terms include:

• Length of the agreement
• Automatic renewals
• Assignability to a new owner
• Termination clauses
• Revenue split terms
• Exclusivity language

Long-term, assignable contracts with clear protections reduce risk. Weak or handshake-only agreements significantly reduce value and limit your buyer pool.

How do buyers calculate value (gross net vs. EBITDA)?

There are typically two primary valuation methods in ATM acquisitions:

1. Gross Net Multiple (Common for Smaller Routes)
This is calculated by taking total ATM revenue minus merchant payouts. Buyers then apply a multiple – often 18–24 months of gross net.

2. EBITDA Multiple (Common for Larger Businesses)
For more established operations with employees and systems, buyers look at adjusted EBITDA (profit after normalizing expenses). Multiples typically range from 3x to 4x, depending on contract quality, growth trends, and operational strength.

Stronger systems and contracts generally justify higher multiples.

How far in advance should I prepare for an exit?

Ideally, you should begin preparing 12–24 months before selling.

This gives you time to:

• Clean up financial reporting
• Strengthen contracts
• Replace personal expenses with true business expenses
• Build operational systems
• Reduce owner dependency

Waiting until you’re “ready to retire” often results in a lower valuation because buyers price risk and disorganization aggressively.

What red flags should stop a deal?

Some red flags that should slow or stop an acquisition include:

• Weak or unsigned contracts
• High revenue concentration in one merchant
• Poor financial documentation
• Unverified equipment ownership
• Significant upcoming contract expirations
• Inconsistent service history
• Seller is unwilling to answer direct questions

One of the most expensive mistakes buyers make is overlooking red flags because they “want the deal.” If something doesn’t make sense, it usually gets worse after closing — not better.

How do you reduce attrition after an acquisition?

Reducing attrition starts before you close the deal.

Key steps include:

• Communicating early with top merchants
• Reinforcing continuity and service quality
• Keeping existing branding when appropriate
• Maintaining key relationships during transition
• Offering additional services to increase stickiness

Second sales are easier than first sales. If you can bundle additional services like merchant services, change orders, and ancillary products, you deepen the relationship and make it harder for competitors to displace you.

Attrition is often the result of poor integration, not the acquisition itself.
