Discount Handling in Mexico’s CFDI System: Main Requirements

In Mexico’s CFDI system, discounts must comply with SAT rules by being recorded in the Descuento field at either the line-item or document level, never as negative product lines. Discounts given at the time of sale are included in the original CFDI of type Ingreso, while post-sale discounts require a CFDI of type Egreso referencing the original UUID.
