Express pay options and guarantee below cart checkout: +6% conversion
Test run byBlend CommerceCRO agency
Commentary byLiftArchiveOur analysis, not theirsAdding express payment options and a '100% satisfaction guarantee' note below the cart checkout button raised conversion rate by 6% for a plants brand.
Blend Commerce ran the A/B test after finding that many orders used Shop Pay, PayPal and Apple Pay.
Two elements changed together, so the lift can't be split between them.
- Conversion rate: +6%.
- PayPal clicks: +6.25%, the biggest gain in payment clicks.
- Shop Pay clicks: +0.5%, likely small because Shop Pay was already shown on product pages.
The change
The variant adds express pay options and a guarantee note below the checkout button.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The cart page had a checkout button with no payment options or guarantee shown below it.
Variant
Below the checkout button, the cart showed express payment options for Shop Pay, PayPal and Apple Pay, plus the brand's '100% satisfaction guarantee' note.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Shoppers who prefer a payment method can see it right away and skip typing card details.
- A guarantee next to the button can ease worry about plants arriving in poor condition.
- PayPal gained most because it was new to shoppers at that point, while Shop Pay already appeared earlier in the journey.
Caveats: The payment options and the guarantee were added together, so the test can't say which drove the lift. Blend Commerce does not share sample size, test length or confidence.

How to run this test on your store
- Hypothesis
- If we show the express payment options our customers already use, plus our guarantee, below the cart checkout button, then more shoppers will check out because paying feels faster and safer.
- Primary metric
- Conversion rate
- Guardrails
- Checkout button clicks
- Share of orders by payment method
- Refund or complaint rate
- Who should test it
- Stores where a large share of orders already use express wallets and where product quality is a worry. Test the guarantee and the payment options separately if you want to know which one works. It will do little if express pay already shows in the cart.
Questions
Should I show express pay buttons in the cart?
If many customers already pay with wallets like PayPal or Apple Pay, showing them in the cart can help.
In this test, conversion rose 6% with them plus a guarantee note.
Does a satisfaction guarantee near checkout help?
It can ease last-minute doubt. This test added it along with payment options, so its own effect is not known.
Which payment options should I show?
Start with the ones your orders already use most. Check your payment reports first.
