How do I save, discard or close a cost I am editing?

It depends on the page. On Products, a variant opens as a page of its own, and so does each cost on Logistics, with a back arrow beside its name in the header. On Transaction fees, a payment method's row opens in place, right in the list. On Overhead, a cost opens in a panel on the right side of the page.

On Products, Logistics and Transaction fees, a small black pill appears at the top as soon as you change something. It reads 1 unsaved change, or Unsaved fee on Transaction fees, and a line under it says what the save will do, like New prices from 1 Nov 2026. Click Save, or press Ctrl and S, or Cmd and S on a Mac. Discard puts back what was saved. While the pill shows, every way out is held: Back, the sidebar, links and a reload. The pill shakes until you save or discard, so a stray click never loses what you typed.

On Overhead, a new cost has Cancel and a save button, like Save cost. Once you change a saved cost, the buttons become Discard changes and a save button. A click outside the panel never throws your typing away: the panel stays open with your changes. Esc closes the panel. With unsaved changes, the first Esc shows a reminder, and a second Esc closes it without saving. Press Ctrl and Enter to save, or Cmd and Enter on a Mac.

To delete a cost on Overhead, open it and click its delete button, like Delete cost or Delete spend. The button then reads Click again to confirm, and a second click within a few seconds deletes it. On Products, Logistics and Transaction fees, each entry in a cost's history has a three-dot menu: Delete this cost on Products, Delete this version on the other two. A dialog says what then counts for those days, and Delete confirms.

If every field is greyed out, you can read the cost but not change it. A dark lock, where the pill would be, says why. After a save, nouz works out the affected days again in the background. The page updates by itself when that is done.
