what is the advantage of applying a discount sku at the header of the sales order

AI generated answer (using internal Slack threads):

Applying a discount SKU at the header of the sales order has several advantages: 1. Simplicity: It simplifies the process of applying a discount to the entire order, as opposed to applying it to each individual line item. This can be particularly beneficial when dealing with large orders with many line items. 2. Flexibility: It allows for the application of a flat rate or percentage-based discount to the entire order, regardless of the individual items or quantities ordered. This can be useful for promotions or special offers that apply to the entire order. 3. Efficiency: It can improve the efficiency of order processing and calculation of gross margins, as the discount is applied at the transaction level rather than the item level. This can make it easier to track and manage discounts in financial reporting. 4. Automation: If your business operates primarily through ecommerce, applying a discount at the header level can be automated with the use of promo codes. This can streamline the checkout process for customers and reduce the need for manual discount application. However, it's important to note that applying a discount at the header level may not be suitable for all situations. For example, if only certain items in an order qualify for a discount, or if you need to apply different discounts to different line items, then applying a discount at the line item level may be more appropriate. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
