Assigning a default currency to your suppliers in Katana ensures purchase orders (POs) are processed in their preferred currency. This streamlines purchasing, prevents manual errors, and keeps financial records consistent across multiple currencies.


Why set a supplier currency?

  • Automatically applies the supplier’s preferred currency to new purchase orders.

  • Helps avoid manual conversions and mistakes when buying internationally.

  • Keeps supplier-specific pricing accurate and consistent.


How to set a default currency for suppliers

  1. Go to the Buy screen > Suppliers tab.

  2. Select the supplier you want to edit — their supplier card will open.

  3. In the Currency field, choose the supplier’s default currency.

From now on, all new POs for that supplier will default to the chosen currency (though you can still manually change it on any PO if needed).


Changing a supplier’s currency

When you change a supplier’s currency, Katana will ask if you want to convert existing purchase prices.

Pop-up confirmation for converting prices for a supplier
  • Yes, convert prices → All default purchase prices for materials/products linked to that supplier will be updated to the new currency using the latest exchange rate.

  • Cancel → The supplier’s currency changes, but purchase prices remain in the old currency.

Warning: Converting may create discrepancies if your purchase prices are already printed on labels, shared with partners, or tied to existing workflows.

Example:

  • Current supplier currency: USD

  • You change it to EUR

  • Katana will automatically convert purchase prices from USD → EUR using the daily exchange rate.


Setting supplier currency from item cards

You can also set or edit a supplier’s currency directly from an item card under the Supply details tab.

This ensures purchase prices for that item match the supplier’s default currency.


Buying in multiple currencies

Once you’ve assigned currencies to your suppliers, you can:

  • Create purchase orders in different currencies.

  • Automatically convert them into your base currency for reporting.

  • Keep supplier relationships and pricing consistent across borders.
