Constants

const (

)

Official SAT codes to include in stamps.

const (
	KeyFormaPago    cbc.Key = "sat-forma-pago"    // for mapping to c_FormaPago’s codes
	KeyTipoRelacion cbc.Key = "sat-tipo-relacion" // for mapping to c_TipoRelacion’s codes

)

Custom keys used typically in meta or codes information.

const (
	TaxCategoryRVAT  cbc.Code = "RVAT"  // IVA (Retenido)
	TaxCategoryIEPS  cbc.Code = "IEPS"  // Impuesto Especial sobre Producción y Servicios

)

Local tax categories

const (
	TaxIdentityCodeGeneric cbc.Code = "XAXX010101000"

)

Constants used to specific tax identity codes.

const (
	TaxIdentityTypePerson  cbc.Key = "person"
	TaxIdentityTypeCompany cbc.Key = "company"
)

Tax Identity Type

const (
	TaxIdentityPatternPerson  = `^([A-ZÑ&]{4})([0-9]{6})([A-Z0-9]{3})$`
	TaxIdentityPatternCompany = `^([A-ZÑ&]{3})([0-9]{6})([A-Z0-9]{3})$`
)

	TaxRateExempt cbc.Key = "exempt"
)

Local tax rates
