# Stricter advance notice on your direct website

You can require more advance notice on your direct website than your PMS sets, without changing the lead times your OTAs use.

**How it works.** Support can configure the **Advance Notice Blocking** module so the site's global window acts as a minimum. Each property's effective calendar window becomes whichever is larger: its synced PMS value or the site's global setting. OTA behavior is not affected, and your website greys out the longer window on every listing's calendar.

**Checkout enforcement.** Checkout follows the site-wide **Validate advance booking hour** setting when that field is non-zero. To enforce the window at checkout as well, set this field to the same number of hours.

**Getting it set up.** This minimum-window configuration is not currently a self-serve module option. Contact support to request it.

Still stuck? [Contact the HomeRunner team](https://homerunner.io/contact/) with your site address and what you tried, and we take it from there.
