Why sale and urgency offers matter on the checkout specifically
At checkout the shopper has chosen what to buy and is deciding whether to pay now.
Urgency here can tip a hesitant buyer over the line, or it can make someone feel rushed at the moment they most need to feel safe.
Kasper Dolk's point is that best practices are too general and don't account for the market you sell to.
Measured results
Removing urgency won big
A post-purchase survey for Kasper Dolk's client said the checkout timer felt like too much pressure for a Dutch audience.
Hiding the timer won +25.61% conversion rate, +26.18% revenue per visitor and an estimated +€150k/month.
In Kasper Dolk's words, the ticking clock made visitors anxious rather than faster.
Small urgency changes won
Dave Diederen ran two tests on the same checkout.
A full checkout update lost on every key metric: -1.18% conversion rate, -1.84% RPV and -1.96% profit per visitor.
Urgency messaging alone won +3.37% conversion rate, +6.59% RPV and +7.13% profit per visitor.
Dave Diederen's takeaway is about test size: a small change gives a clear signal, while a full redesign leaves you guessing what helped or hurt.
Trust plus urgency
Kasper Dolk added trust and urgency elements to a Shopify Plus checkout for an accessories client: Trustpilot widgets, UGC and before/after images, plus a timer and low-stock notices on select items.
Kasper Dolk reported it was adding $33,435 while the test was still running.
With so many elements in one variant, the urgency share is unknown.

@kasper_dolk@kasper_dolkLosing or flat tests
The full checkout redesign in Dave Diederen's test is the clear loser in this set, at -1.18% conversion rate.
The timer in Kasper Dolk's test was also effectively a loss: the store did better without it.
With only three results, the evidence is thin.
It is enough to show that checkout urgency can cut both ways, not enough to say which way it will go for you.
Untested ideas
- Dave Diederen suggests an order-reserved timer, a "free shipping reached" message, shipping protection, USPs and reviews beside the order summary, plus FAQs on the main objections.
- Dave Diederen also suggests a 10-minute checkout countdown through a custom app (Shopify Plus required).
- Kasper Dolk suggests a "total savings" block that shows all savings in one place, paired with a limited-time timer.
- Kasper Dolk suggests replacing a plain Stripe checkout with a custom native-feeling one that adds a timer, faces for trust, and benefits with objection handling.
Placement and design patterns that won
- Keep it light. The win that added urgency used messaging, not a full rebuild.
- Ask your customers. The largest result came from a survey that flagged the timer as pressure.
- Pair urgency with trust. Kasper Dolk's checkout combined the two rather than running urgency alone.
- Consider moving urgency earlier. Kasper Dolk's advice after the removal win was to add urgency on the product page and in the cart instead.
How to test it
Change one thing at a time, measure revenue per visitor and profit per visitor, and split results by country if you sell in several markets.
