SalesTaxFunction

Name

SalesTaxFunction — specify custom tax calculation function

SYNOPSIS

subroutine_name

DESCRIPTION

The directive specifies custom sales tax function.

The function return value has to be a Perl hash, just like other Interchange tax calculation methods would return. Make sure the "DEFAULT" value is returned, or the tax will unconditionally yield zero.

Example: Calculate tax amount based on vendor

SalesTaxFunction  <<EOR
my $vendor_id = $Session->{source};

my $tax_hash = $TextSearch->hash( {
  se => $vendor_id,
  fi => 'salestax.asc',
  sf => 'vendor_code',
  ml => 1000,
  } );

$tax_hash = {} if ! $tax_hash;
$tax_hash->{DEFAULT} = 0;

return $tax_hash;
EOR

Example: Calculate tax

return {
  DEFAULT => 0.0,
  IL => 0.075,
  OH => 0.065,
