You can assign a default currency to each supplier in Katana when creating Purchase orders.
This is especially useful when you are buying internationally as it automatically assigns the accurate currency to purchase prices on the Purchase orders.
Your supplier's currency will be used as a default currency on the Purchase orders for that supplier - but you can always go ahead and choose another currency for a specific order.
Adding a default currency for suppliers
Navigate to Contacts screen > Suppliers table.
Choose the currency in the Currency field of a supplier and this will be set as default for that supplier.
When changing your supplier currency, Katana will enable you to convert the existing default purchase prices for all materials and products with that supplier to the new default currency based on the currency exchange rate.
Selecting Yes, convert prices will start the default purchase price conversion process. Selecting Cancel will not change the currency and the default purchase prices won't be converted.
Example: If you set your current purchase prices in base currency (eg. USD), changing the currency on your supplier (eg. to EUR) will convert default purchase prices of all items which have this supplier set as default to the converted amount in EUR (using automatic conversion rate for USD > EUR).
Supplier currency can also be changed on the item card where default purchase prices are kept. Read more here about how to handle default purchase prices in your supplier's currency.
When you set supplier currency and purchase prices, you can start buying in multiple currencies.
