Ordering > Kitchen > Meal Prices (/admin/mealsprices) lists every meal in one grid - inactive meals are shown too, flagged "- INACTIVE" next to the name - with columns for <Default> Selling Price (with the production price underneath), <Default> Surcharge, <Default> Regular Price, and for every Meal Prep portion size an Upgrade and a Surcharge column. Click any value to edit it in place and press enter - it saves immediately. A new selling price that is not below the meal's regular price (when a regular price is set) is silently rejected, as is a regular price below the selling price. Use the search box, sorting and (if exports are allowed for your account) the Copy / CSV / Excel / PDF / Print buttons.
