The Economics of Trust

I complained. After some discussion, the supermarket refunded both the missing item and the delivery charge. It was a small claim, but it mattered to me: the minimum order value meant I could not simply replace the steak, so lunch plans had to change.

A few days later, I found it in another part of the fridge.

The supermarket had not made a mistake. I had.

I felt embarrassed—but something else happened too. My trust in the company increased dramatically. They had believed me when, as it turned out, they had every reason not to.

The cost of being right

The experience reminded me of a billing-compensation policy I introduced earlier in my career.

For claims below an agreed threshold, we allowed the customer’s requested refund without carrying out further checks.

At first sight, this might sound commercially naive. It was not.

Investigating a small claim consumes employee time, creates additional contacts and increases the likelihood of escalation. Even when the company proves itself right, it may spend more defending the charge than the charge was worth—and lose the customer’s trust in the process.

Our policy reduced escalated complaints and lowered the total cost of handling them.

The objective was not to give customers everything they requested. It was to make a rational decision about where the company should invest its effort.

Trust still needs judgement

A trust-based policy does not mean ignoring fraud or removing every control.

It means designing controls proportionately.

The value of the claim, the customer’s history, patterns of repeated behaviour and the cost of investigation should all inform the decision. A high-risk or unusually large request may require scrutiny. A small, credible claim may not.

Technology and AI can make that judgement more informed. They can identify patterns, assess risk and help distinguish an isolated problem from systematic abuse.

But the starting question remains commercial:

Is the cost of challenging this customer greater than the cost of resolving the issue?

Look beyond the transaction

The supermarket refunded a relatively inexpensive item. In return, it gained something more valuable: my confidence that, if a genuine problem occurs in the future, it will be handled fairly.

Not every customer will later discover that they were mistaken. Not every act of trust will generate loyalty.

But businesses should understand the full economics of a service decision: the refund, the handling cost, the risk of escalation and the future value of the relationship.

Sometimes trusting the customer is not generosity.

It is simply good business.
