Hi,
You want to configure the "waitlist" feature.
You need to do several things for that:
- activate the "Activate Waitlist feature" setting in the HikaShop configuration
- make sure that your cron is running:

- make sure that the HikaShop waitlist plugin is enabled and configured like you want in the Joomla plugins manager
