+SL::DB::PaymentTerm - Rose model for the payment_terms table
+
+=head1 SYNOPSIS
+
+ my $terms = SL::DB::PaymentTerm->new(id => $::form->{payment_id})->load;
+ my $due_date_net = $terms->calc_date(terms => 'net'); # uses terms_netto
+ my $due_date_discount = $terms->calc_date(terms => 'discount'); # uses terms_skonto
+
+ # Calculate due date taking the existing invoice date and the due
+ # date entered by the user into account:
+ my $due_date = $terms->calc_date(
+ reference_date => $::form->{invdate},
+ due_date => $::form->{duedate},
+ );
+
+=head1 FUNCTIONS
+
+=over 4
+
+=item C<calc_date [%params]>
+
+Calculates and returns a due date as an instance of L<DateTime> by
+adding one of C<$self>'s terms fields if automatic calculation is on;
+otherwise returns the currently-set due date (which must be provided)
+or the reference date, whichever is later.
+
+Note that for automatic calculation the resulting date will be the
+following Monday if the result falls on a weekend.
+
+C<%params> can contain the following parameters:
+
+=over 4
+
+=item C<reference_date>
+
+The reference date from which the due date will be calculated. Can be
+either an instance of L<DateTime> or a scalar in which case the scalar
+is parsed via L<DateTime/from_kivitendo>.
+
+Defaults to the current date if unset.
+
+=item C<due_date>
+
+A currently set due date. If automatic calculation is off then this
+date will be returned if it is provided and greater than or equal to
+the C<reference_date>. Otherwise the reference date will be returned.
+
+=item C<terms>
+
+Can be either C<net> or C<discount>. For C<net> the number of days to
+add to the reference date are C<$self-E<gt>terms_netto>. For
+C<discount> C<$self-E<gt>terms_skonto> is used.
+
+Defaults to C<net> if unset.
+
+=back
+
+=item C<validate>

+messages in case of an error.
