Temporary items in quotations and invoices

Hello dear forum members,
is it possible to create items in quotations and invoices that are not based on articles?
We work project-related and it is useless for us to store everything in articles except hourly wages.

Thank you very much for your help.

That was discussed before. I believe that for Sales Quotation they were developing something for that.

I usually create an Item like “Project Item”, but in the print format of the quotation I just print line description. And I enter project-related info to the description field.

Thanks for your answer.
Do you know where I can find the development?
Many thanks.
