Owners do not need more dashboards. They need a clean answer when a supplier move starts eating the menu.
Store price history with source, pack size, and date.
Compare new invoice lines against recent history before approval.
Translate supplier movement into menu impact, not just admin noise.
Example
Example: chicken thighs rise 8% on a new invoice. Before approval, Karu ranks which menu items, prep batches, and combos inherit the move so you update prices or portions where it actually hurts.
Checklist
Upload the latest supplier invoice into the inbox.
Compare pack size and unit before trusting the line total.
Approve only after checking the affected recipes.
Act on the top exposed products the same day.
