Summary

Best practices for checkout flows

The checkout is the moment of truth. Visitors are entering personal details, committing to a financial decision and trusting they've made the right choice. Yet most companies abandon all persuasion the instant the funnel begins. The warmth, social proof and support options that defined the rest of the journey simply vanish — replaced by a cold, clinical form.

This whitepaper from WUA identifies what separates high-converting checkout flows from those that quietly leak conversions.

The problem: clinical forms create doubt

A checkout that offers no visible help, no product summary, no reassurance and no progress indicator puts the entire burden on the visitor. They have to remember what they selected, figure out how long the process takes and find support if they get stuck. At the exact moment where confidence matters most, these flows offer nothing.

The solution: keep convincing throughout the form

The best checkout flows don't stop selling when the form starts. They:

Keep the selected product visible so visitors never wonder what they're buying or what they'll pay
Reinforce benefits and USPs below the form, not just on the landing page
Show human support options — a real photo, office hours and a phone number — so hesitating visitors have a way forward
Set time expectations with a progress bar and a message like "All done in 2 minutes"
Place trust signals near the CTA, where doubt peaks

Engie.nl is highlighted as a strong example: a persistent "Your choice" sidebar, ongoing benefit reinforcement and a visible help block with a real person's photo all reduce friction at the critical moment.

What to do next

Use the included checklist to audit your own checkout flow. If you're unsure how your flow stacks up against competitors, WUA offers a free 30-minute review to identify friction and surface concrete opportunities for improvement.

Key Takeaways

Most checkouts stop selling the moment the form starts. That's where visitors drop off.
No product summary in the checkout? Visitors have to remember what they picked. They won't.
Show a phone number or chat option at every step. Hesitating visitors need a way forward.
A progress bar reduces uncertainty. Tell visitors it takes 2 minutes. They'll believe you.
Keep showing benefits and USPs inside the checkout, not just on the landing page.
Place trust signals near the CTA and payment fields, where doubt is highest.
Transparent pricing from the first click prevents surprises. Surprises kill conversions.
