You can set up a default currency for your vendor ahead of time by selecting the corresponding currency in that vendor’s record. By selecting a default currency for that vendor it will override your system default.

The easiest way to manage this however, is to change the currency during your purchase order and save it back to the vendor record. To do this:
- Click into the Currency drop down (in the bottom left hand corner of your screen).
- Choose the correct currency from the drop down then hit tab.
- Enter the correct conversion rate in the field that now appears below.
- When you save your order you will be asked if you’d like to make this your vendor’s default; say yes.
