Katana allows you to manage purchases in multiple currencies, making international procurement easier and more accurate. Purchase prices can be kept in foreign currencies and are automatically converted into your base currency, ensuring stock valuations always remain correct in your local reporting currency.
What you can do with multi-currency purchasing
Create purchase orders (POs) in foreign currencies.
Keep order currencies updated daily with the latest exchange rate.
Fix the exchange rate on a PO to prevent further updates.
Manually edit the rate and date if needed.
Creating a purchase order in a foreign currency
Click the global + Create button and select + Purchase order.
Select a supplier with a non-base currency.
The PO currency will automatically default to that supplier’s currency.
Katana will calculate PO row prices in the order’s currency:
If using the supplier’s default currency → your default purchase price is applied directly.
Example: Supplier currency is GBP and purchase price is 300 GBP → PO shows 300 GBP per unit.
If using a different supplier with a different currency → Katana converts the price.
Example: Item default purchase price is 300 GBP, but PO is in USD → price is automatically converted into USD.
The converted total and conversion rate are displayed in the PO’s totals section.
How currency conversion works
Katana updates PO exchange rates daily, so open POs always reflect the most up-to-date values.
You can fix the rate at any point to lock it.
Once fixed, the Currency field becomes locked, but you can still edit the rate and date manually.
Fixing or changing rates
Fixing a rate ensures your PO values remain stable, even if exchange rates change later.
If you change the supplier on a PO to one with a different currency, Katana will ask if you want to convert the prices to that supplier’s currency.
After fixing, you can still manually edit the exchange rate to match negotiated terms with your supplier.
Additional notes
Supplier default currencies can be set on the supplier card or item card (read more).
Multi-currency ensures accurate stock valuation, since all foreign currencies are always converted into your base currency.
