Why customize checkout

Your highest-intent page, finally in your control

Checkout is where buyers are ready to pay — the perfect moment to raise order value, reassure hesitant shoppers and steer the experience. Do it all with widgets and rules, no developer needed.

Increase Order Value

Checkout upsells, order bumps and quantity discounts nudge buyers to add more right before they pay.

Build Trust & Reduce Drop-off

Trust badges, free-shipping bars and clear delivery estimates reassure shoppers and cut abandonment.

Control the Experience

Hide, rename and reorder shipping and payment methods, and target every widget with precise rules.

20+ checkout widgets

Every block your checkout needs

Drop in revenue-boosting offers and reassuring content across checkout, thank-you and order-status pages — each with display rules, scheduling, A/B testing and translations.
