Field notes
The estimate exposes its assumptions: tax treatment, exchange-rate date and source, and a user-adjustable card-fee rate. The page says users enter their own subscription amounts and billing dates, with no card or bank connection. A later expense-report feature is described as using ECB rates by billing date and exporting a freee-format CSV, but that capability is presented as planned rather than available.
