If you want to increase a Moulding Category (does not apply to individual
mouldings if they have had an individual price set) or any other item (i.e.
glass, backing etc.) it is easy to do. Say for instance that you want to
increase the price "Clear Glass Square" by 15%.
From the main menu go to 6. Maintenance and then 6. Pricing menu and then 1. Input Framing Price Details. Now press the "F" key until you get to the glass item.

Now press "A" for A)djust
Enter a % increase amount (in our example 15) and Accept the prices.
That's it. That item will now cost 15% more. This works for all items including mouldings where the moulding is related back to a pricing category.
