To integrate a discount, simply create a new line on the quote and label it as a discount. You can add it to an existing section if the discount applies to a specific room. Alternatively, you can create a new section titled "Discounts", which will allow you to add multiple items if needed to detail certain aspects.

Next, to apply the discount, enter a negative price on the line(s) for the discount(s), and the total of the quote will automatically update.
