`default_vat_treatment` (VAT handling default)
default_vat_treatment (VAT handling default)
default_vat_treatment is the party’s default VAT handling suggestion. Some counterparties consistently imply a VAT handling pattern, especially foreign vendors and platforms, and a default treatment makes pre-filling reliable.
Defaults should remain overrideable per line, because VAT treatment can still differ by item or context even when the counterparty is the same.
Example values: domestic_standard, reverse_charge.
For cross-border counterparties, a treatment such as intra_eu_supply can be used as a default to make EU vs domestic validation deterministic, while still allowing line-level overrides.
