If you use JS to write checks and you recieve a COD invoice, you need
to quickly issue and print a check, but you don't have time to type
in the details of the invoice while the courier is waiting.
1) Enter the invoice from screen 2,3 and put the full amount into the bin
called OTHER EXPENSE, and don't bother with the inventory details at this
2) Record the check against this invoice and print
3) Later, edit the invoice (from screen 2,4), remove the
OTHER EXPENSE AMOUNT and type in each inventory item.
