Reduce the time your accounting team spends on manual classification with new rules and field mapping capabilities, including:

- If/then logic in accounting fields so that a change in one field will trigger an appropriate change in a related field.
- Rules that nest down for budgets, e.g., you can apply a rule to a higher-level parent budget and it will apply to all its child parent rules.
