The $3.7 Trillion Cost of Guessing About Your Customers

Last week, I had coffee with a C-suite exec who looked exhausted.

"We just launched a customer service chatbot," she told me. "Spent six months and a quarter-million dollars building it. Our CEO loved the demo."

I asked how customers felt about it.

She winced. "We're getting complaints....(ugg)...A lot of them."

They never asked customers what they actually wanted. They assumed.

And that assumption just cost them a quarter-million dollars, plus the revenue walking out the door with every frustrated customer.

This isn't unusual. It's rampant.

And it's costing companies $3.7 trillion globally in at-risk revenue right now.

The uncomfortable math of flying blind

I've been consulting with businesses for over 15 years, and I see this pattern constantly. Smart executives making decisions based on hunches, competitor copying, or what some guru said at a conference.

They'll agonize over a $50,000 software purchase — demanding three vendor demos, building comparison spreadsheets, negotiating every dollar. Then they'll launch a customer service initiative affecting thousands or even millions of customers without spending a dime to understand what those customers actually need.

The irony is brutal. Customer service research typically costs a fraction of the initiatives it informs. Yet companies skip it, then wonder why their expensive solutions fail.

Here's what the numbers actually show:

A 2022 Forrester study found that improving your customer experience score by just a single point can generate between $38 million and $1.1 billion in incremental annual revenue, depending on your industry.

That's not a typo. One point.

Now think about how much research it would take to identify what would move that needle. A fraction of the potential return.

The 25-to-95 percent profit multiplier

The most cited statistic in customer experience comes from Bain & Company research: Increasing customer retention by just 5% increases profits by 25% to 95%.

I love this finding because it reveals something most executives miss — small improvements in understanding and serving customers create exponential returns.

But here's where it gets interesting. The same research shows that acquiring a new customer costs 5 to 7 times more than retaining an existing one. Some industries see the multiplier as high as 25x.

So the math becomes absurdly simple:

- Spend a little to understand why customers leave.

- Fix those issues.

- Keep 5% more customers.

- Watch profits jump by as much as 95%.

Yet most companies do the opposite. They spend enormous budgets hunting new customers while existing ones quietly slip away — often for reasons that could have been discovered and addressed with basic research.

The trust collapse that changes everything

Here's what makes this urgent right now.

72% of consumers trust companies less than they did a year ago. Not a little less. Significantly less.

At the same time, 52% of customers will switch to a competitor after a single unsatisfactory experience. One strike and you're out.

Think about that combination. Customers trust you less and tolerate mistakes less. The margin for error has essentially disappeared.

This creates an asymmetric risk that should terrify every executive: The cost of getting customer service wrong is exploding, while the cost of getting it right through research remains modest.

The $12.9 million decision-making tax

Here's a number that should make every executive uncomfortable: Bad data costs organizations $12.9 million per year on average, according to Gartner.

That's the cost of making decisions without accurate information. Wasted marketing spend targeting the wrong people. Failed product launches solving problems that don't exist. Service initiatives that frustrate rather than help.

Customer service research isn't an expense. It's insurance against the far larger cost of operating blind.

I think about my coffee conversation with that exhausted CMO. Her company spent $250,000 building a solution to a problem they never verified existed. Customers are now complaining, which means retention is dropping, which means customer lifetime value is declining.

That bad decision will likely cost 10x the initial investment by the time they fix it. And all of it could have been avoided with a $25,000 research project to understand what customers actually wanted.

What your competitors understand

I talked to a Fortune 500 VP last month who told me they planned to "invest in customer experience next quarter."

I asked what their current customer satisfaction scores were. He didn't know.

I asked what their retention rate was. He had a vague number but wasn't sure.

I asked what their top three customer pain points were. He guessed.

This isn't incompetence — he's a smart executive. It's operating without information in a world that demands precision.

Meanwhile, his competitors are running systematic research programs. They know their Net Promoter Scores. They track First Contact Resolution rates. They measure customer lifetime value and know exactly what drives it up or down.

Watermark Consulting found that CX leaders outperformed the S&P 500 by 260+ points over 16 years. These weren't companies with better products or bigger marketing budgets. They were companies that understood their customers better.

The competitive advantage isn't mystery. It's measurement.

So here's what I'd ask every business leader: What's the cost of being wrong about what your customers want?

Because in 2025, with trust at historic lows and switching at historic highs, that cost has never been greater.

In Part 2, I'll share the real numbers behind research ROI — including how Disney turned a billion-dollar bet into exponential returns, and why companies investing in customer understanding grow 4-8% faster than their competitors.
