Scheduled orders let guests order now for a later time. With a Toast integration you turn them on in two places: Toast and Owner.
Sign in to your Toast Dashboard.
Go to Takeout & delivery > Availability > Online Ordering
Scroll down to Online Ordering Scheduling Settings. Under Enable Scheduling, make sure that "Yes, guests may schedule orders" is checked.
⚠️ Turning this on in Toast is only half of it. Scheduled orders also have to be on in your Owner Dashboard, under Settings › Orders and delivery, or guests still won't see the option.
Scheduled order rules
ℹ️ Note: Toast lets you set rules so certain items can only be scheduled on certain days. Owner can't support those rules, because that detail doesn't reach us from Otter.
