Under Warehouse/Materials you will find all materials stored in Keyline, including paper.
As soon as you have selected a paper in a cost estimate for the first time, Keyline creates the paper for you in material management.

There you can browse the stock, duplicate or delete materials, or make all settings such as order behavior, stock, prices, category, dimensions, etc.

Paper is always created in the admin area under Materials/Paper. Either via a paper import, or individually manually.

Create and manage your own papers
