Checkout as the critical point of the funnel
Checkout is the last barrier between the intent to buy and the purchase itself. The shopper has
already chosen the products and already put them in the cart — and this is exactly where 20–35% of
them leave without finishing.
Checkout optimisation runs along two tracks that are worth keeping separate:
- Checkout CRO — removing friction: fewer steps, guest purchase available, all costs shown up front
- Checkout monetisation — raising average order value: recommendations, upsell, a nudge to reach
the free delivery threshold
The structure of a typical checkout
Cart → Delivery address → Delivery method → Payment → Confirmation
One-page checkout — every step on a single screen with no reloads — is increasingly the default
in e-commerce. It lowers the abandonment rate by removing the friction of transitions.
Personalization at checkout
Important: personalization at checkout has to add value, not distract. A survey popup on the
payment screen is a bad idea.
Patterns that work:
| Scenario | Trigger | Goal |
|---|---|---|
| Cross-sell block | Items in the cart | Add a complementary product |
| Free delivery threshold | Cart value below X | Add one more item |
| First-purchase promo code | New customer | Lower the barrier to the first conversion |
| Basket composition check | Product types | Suggest a compatible accessory |
The usual mistakes
- Hidden costs until the last step — the single biggest cause of checkout abandonment
- Mandatory registration — it blocks unauthenticated shoppers; guest checkout removes the problem
- Aggressive personalization — popups and remarketing banners during payment reduce conversion
