Both markdowns and sales discounts involve the reduction of price – but for different reasons. A markdown is an adjustment of price to reflect a lower market value, whereas a sales discount doesn’t change the valuation of a good or service. Instead, discounts are reduced rates offered for specific reasons – such as seasonality, customer loyalty or demographics (such as discounts for students or pensioners). (SumUp Invoices)
