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.

Best practices for checkout flows

The do's and don'ts of checkout flows

The checkout flow is where visitors have to commit. They're filling in personal details, making a financial decision, and trusting they're picking the right option.

Yet a lot of companies drop all persuasion the moment the funnel starts. The warmth, social proof and help options vanish. What's left is a cold, clinical form.

Clinical forms create doubt

Instead of guiding visitors, many checkout flows present nothing but input fields. The visitor is left to build their own confidence to continue. That increases the chance of drop-off at the exact moment where clarity and reassurance matter most.

Proactive helpfulness drives conversion

The checkout flows that actually perform well keep selling, reassuring and supporting throughout the form. They keep the selected product visible, reinforce benefits, offer help and make the process feel guided rather than bureaucratic.

Let's look at two examples that show this difference.

A checkout that feels like a tax form

This page offers no support. The visitor is left on their own at the moment of decision.

No visible help options There's no phone number, chat option or contact link anywhere in the flow. A visitor who has questions has to go back to the homepage and search for a support page.

No product summary The selected product, price and configuration are no longer visible next to the form. The visitor has to remember what they picked earlier.

No reassurance USPs, benefits and brand elements disappear completely once the checkout starts.

No progress bar There's no indication of how many steps remain, how long it takes or what happens after the form. The visitor has zero sense of control.

A checkout that offers reassurance

The best checkout flows don't just collect data. They keep convincing, helping and reassuring at the exact moment the visitor decides.

Engie.nl

Progress indicator "All done in 2 minutes" and "You're almost there" sets expectations. A progress bar and a step indicator that shows "Your personal details (1/3)" lets the visitor know how quick this process will be.

Persistent product summary A blue "Your choice" sidebar shows the selected plan, monthly amount, annual cost and a loyalty bonus. No need to wonder what they picked or what they'll pay.

Ongoing benefit reinforcement "Below the price summary, the benefits reinforce why this provider is the right choice, while "14 days to reconsider" in the subtitle removes risk.

Visible, human help A "Need help?" block shows a real person's photo, office hours and a clickable phone button. The visitor who hesitates sees a way forward without abandoning the form.

Checklist: Checkout flow

Use this checklist to assess whether your checkout flow supports and convinces or unintentionally creates friction:

Is a phone number, chat option or contact link visible at every step of the checkout flow?

Does the selected product, plan or configuration stay visible throughout the checkout process?

Are brand benefits and USPs reinforced inside the flow, not just on the landing page?

Are trust signals (reviews, badges, guarantees) placed near the CTA and payment fields?

Does the flow set time expectations (e.g. “Takes ~2 minutes”) to reduce uncertainty?

Can the visitor navigate back to a specific step without losing their progress?

Is the full price breakdown transparent from the first click, with no surprises at the end?
