=item C<taxes>
A hash reference with the calculated taxes. The keys are chart IDs,
the values the calculated taxes.
+=item C<amounts>
+
+A hash reference with the calculated amounts. The keys are chart IDs,
+the values are hash references containing the two keys C<amount> and
+C<taxkey>.
+
+=item C<amounts_cogs>
+
+A hash reference with the calculated amounts for costs of goods
+sold. The keys are chart IDs, the values the calculated amounts.
+
+=item C<assembly_items>
+
+An array reference with as many entries as there are items in the
+record. Each entry is again an array reference of hash references with
+the keys C<part> (an instance of L<SL::DB::Part>), C<qty> and
+C<allocated>. Is only valid for invoices and can be used to populate
+the C<invoice> table with entries for assemblies.
+
+=item C<allocated>
+
+A hash reference. The keys are IDs of entries in the C<invoice>
+table. The values are the new values for the entry's C<allocated>
+column. Only valid for invoices.
+
+=item C<exchangerate>
+
+The exchangerate used for the calculation.
