Before you invest in the checkout flow

It is rarely the thing that gets a project approved, and often the thing that decides how it goes. Before you spend anything on the checkout flow, it is worth confirming a few things are already true.

Trust does most of the selling online, and trust is built from unglamorous details. If two people in the business would answer this differently, that gap is the actual problem.

Prerequisites

• You can describe the outcome you want in one sentence
• Someone owns it after the work is done
• Every extra step loses a measurable slice of buyers
• You have a way to tell whether it worked

Warning signs

Show total cost early, because surprise fees kill carts. The reasoning matters more than the rule, because the rule has exceptions. If it only works because one person remembers to do something, it does not work yet.

Save progress so a dropped connection is not fatal. The reasoning matters more than the rule, because the rule has exceptions. Anything you cannot measure here, you are deciding by taste, which is fine as long as everyone knows it.

In practice

In e-commerce every friction point has a price attached, and the arithmetic is unusually easy to check. Three things worth confirming about the checkout flow before you move on:

• Someone can say what the current setup is without going to look
• Every extra step loses a measurable slice of buyers — and you know whether that is true here
• There is a way to tell whether the last change to this helped

If you want a second opinion on how yours is set up, ask.
