This enhancement improves transaction synchronization by
automatically linking counterparty IBANs from GoCardless to
existing Firefly III accounts, ensuring more accurate
reconciliation and better data integrity. Users benefit from
reduced manual effort in matching transactions, fewer duplicate
payees, and cleaner financial records that reflect real-world
banking relationships. The implementation caches all account
types during discovery, adds IBAN lookup logic with fallback to
payee creation, and filters CLI account lists to focus on
user-managed asset and liability accounts while maintaining
full backward compatibility.
Having all details available is useful. For Firefly III some fields like
current balance are left out, because they are not strictly account
metadata, but are a result of the transactions in the account.
