Customers don't remember the middle. They remember the peak and the end

Nobel laureate Daniel Kahneman and his colleagues described a strange property of memory: we don't rate an experience as the average of all its minutes, but by two points — the strongest moment (the peak) and the ending (the end). In experiments, people paradoxically preferred a longer unpleasant procedure if it ended more gently. The middle dissolves. The peak and the end remain.

Your project has a peak and an end too

Now replay a project through the customer's eyes. The peak was probably a crisis resolved, the day it first worked, the moment you saved their deadline. And the end? For many companies, the last interaction of a project is the invoice and a payment reminder. Months of good work flatten in memory — represented by the final impression: a piece of paper with a number.

The end can be designed

The good news: the end is the one part of the experience fully in your hands, because it comes when the work is done. A closing call instead of just an invoice: what went well, what we learned, what to watch next. A small unexpected touch — an extra guide, a free check-in after a month. None of it costs almost anything; someone just has to do it deliberately and on time.

The end is also the start of the next deal

Peak–end is why referrals and renewals are born from the last impression, not the average of the collaboration. A customer whose final memory is a caring call refers you and comes back; a customer whose final memory is a payment reminder “was satisfied” but won't pick up. It works in miniature too: the end of every meeting — a summary and a next step with a date — is the ending the customer takes home.

What to take away

Go through your last three closed projects and be honest: what was the very last interaction? If it was the invoice, you've found a cheap opportunity — plan the ending before it arrives.
