# Slots

> Strategic placement points where components transform your checkout experience

Slots are predefined blocks that structure a [Template](https://docs.ollie.shop/ollie-shop/concepts/templates) in Ollie Shop. Each slot is filled with a native component by default, but you can easily replace it with your own — no need to rebuild your entire checkout.

This modular approach lets you customize specific parts of the checkout experience while maintaining speed and stability.
