If you have an invoice that states
15 assembled units 12.95 ea total $194.25
Sales tax 6% 11.66
Subtotal 205.91
Transportation-parcel post charges 25.89
Total invoice $231.80

And you need to put the transportation cost in your sales register, which category would you enter it under: Sales Credit (401, 402), Trans Credit (04011, 04021) or general ledger amount credit? I have never had this situation happen before and need some help. Your help is appreciated
