One of our regular clients is overseas and has to pay withholding tax on some line items (e.g. conference talk honorarium) but not others (e.g. train fares). We do not know the withholding tax amounts in advance, so we invoice them for the full amount. They will send us a part-payment which should fully pay the non-taxable items and the remainder of the payment should be credited to the taxable items. It's not possible to determine which line items the payment should be credited to at the moment, meaning I need to create a workaround. It would be better if it could all be done easily.
