Considerations

Caution

Enabling multi-currency support in Salesforce is irreversible. You cannot turn it off again. Before you enable it, weigh the long-term impact: every relevant record and user will need currencies assigned, you will maintain exchange rates, and you will likely need tailored reports to understand financials across currencies.

With multiple currencies enabled, operational complexity increases across your organisation. Plan for how you will administrate exchange rates and how teams will interpret data that spans more than one currency.
