During the initial connection of Katana to Xero, you are asked to map Xero ledger accounts and taxes to Katana.

There is no Xero integration configuration section in Katana that you could access after the initial connection.

However, you can change the integration configuration by disconnecting your Xero account from Katana and then reconnecting. Katana remembers your previous integration settings, so all your mappings are already prefilled when reconnecting. You can then edit those mappings as you progress through the connection flow.

When the reconnection is completed, your Xero integration settings are updated.
