Discounts are Conceptual Items within your Inventory that you add to individual Orders. Within RW, you have the option of creating Flat Discounts…
Discounts are useful when you want to take a certain percentage or a flat rate off of an Order Total.
Imagine that Promotional Credits are more like a gift card. They do not lower the Order Total at all. Instead, you record them as payment (like you would cash or check), but you don’t actually receive money from the customer.
Speak with your accountant about when you should use Discounts or Promotional Credits in your particular rental business.
