About rules

Firefly contains a rule engine that can automatically update your transactions when they are created or when they are changed.

It works by combining your custom “triggers” and combining them with “actions”.

This is especially useful when you’re importing data and you wish all transactions to be updated at once.


Notable triggers include the amount of a transaction or the description. Firefly could respond when a transaction is less thant € 5,- and contains the word “Groceries”.


Firefly can update the description, change accounts, set a budget or a category, etc etc.


Please note that all triggers are AND. So all triggers must be met before the actions will fire.
