this question was originally posted in 2009 in the forum, with no answer:
And there is a more realistic case for companies doing import/export: Two manufacturers send goods in a truck, this means two supplier invoices. The company gets one invoice from a foreign transportation company and one from a domestic transportation company. The company gets one more invoice from the agency that handles customs paper work. Altogether 2 invoices from the manufacturers share the costs of the 3 other invoices. These costs have to be distributed among the stockable products of the manufacturers' invoices and cost prices adjusted accordingly.
How to handle this?
Why should the products from domestic share cost of foreign company? Just do the calculation: cost price for domestic, cost price for foreign (including customs/agent), add them together and divide by amount of product (assuming both manufacturers make same product).
But what about the invoicing, I have an Invoice from supplier, transport company, customs costs and tariff , Import Taxes and clearance service. My problem is in accounting. I should enter my taxes differently for each of them and their expenses should go to different accounts.
