It is currently not possible to apply coupons to one-off invoices.
However, e-commerce companies make extensive use of one-off invoices, and often need to apply coupons (redeemable through promo codes).
Example of a one-off invoice with coupon:
  • Product 1 (add-on) = $50
  • Product 2 (add-on) = $80
  • Shipping fees (add-on) = $5
  • Promo code (coupon) = $10
  • Total invoice before tax = $125
