We [1] have been using Typst to generate PDF documents in production for a few months, such as invoices and labels. It's generating thousands of documents daily, and I'm glad that some of them are printed and used by people in the warehouse who are doing real work.
I really like the simple syntax that Typst provides. It would be much harder for the PMs to edit the templates if we went with other solutions, such as wkhtmltopdf.
We also looked into other document generation services that provide a WYSIWYG interface, and they are all quite expensive and often lack advanced scripting capabilities.
