Can orders automatically be marked as delivered?

Yes, you can use the [Automatically mark as delivered] feature.

- Note that this feature automatically marks orders as delivered after a set period of time, regardless of whether the order has actually been delivered.

Make sure you do not set a time period that is too short since that will mark orders as delivered before customers have received anything.

Settings

1. Go to [My Store>Store setup>General settings>Orders (tab)] on your admin page.

2. In the [Orders/Shipping settings] section, click on “Yes” for [Automatically mark as delivered] and choose a period after which you wish to automatically mark orders as delivered.
