QB Issue Resolution:

You experience the following scenario:

  1. You create an Estimate for a customer in US Dollars.
  2. From the Estimate, you create a PO to a foreign vendor.
  3. The PO brings over the items, but the rates (Costs) of the items are the same numbers as on the Estimate, only in the foreign currency.
  4. Because the rates are not converted properly, all of the amounts on the PO are incorrect.
Why this is happening

This is a known issue in QuickBooks Multicurrency.

Workaround
  1. Download the current exchange rates.
  2. Manually convert the Rates to the correct foreign currency amounts.
  3. The amounts on the PO should be correct.
