Tags are a new way of keeping track of orders. Examples you can use them are tagging types of printing, presses, print locations, people, tax types and more.
To use a tag, create/edit an invoice, click on "+ Tags" and type in the tag. You will need to start with "#" first.
You can now search for these tags as well by searching like this:
Lastly, on the calendar, you can click "Filter" on the top right to filter by tags as well. This will be helpful, for example, when viewing all embroidery orders that are using the status "In Progress".
Note: Tagging is a Premium feature
