# HOUSEBOT-079 Settlement Currency And NBG FX
|
|
|
|
## Goal
|
|
|
|
Make household balances settle in a configurable household currency while preserving original entry currencies.
|
|
|
|
## Scope
|
|
|
|
- add a household `settlementCurrency` setting, defaulting to `GEL`
|
|
- open new billing cycles in the settlement currency by default
|
|
- keep rent rules in their original source currency
|
|
- convert rent, utility bills, and purchase entries into the billing cycle currency for settlement
|
|
- lock cycle exchange rates in the database once the configured reminder day has passed
|
|
- use NBG as the FX source for GEL conversions
|
|
- show both original and converted amounts in the mini app when they differ
|
|
- default utility entry currency and bare purchase parsing currency to the household settlement currency
|
|
|
|
## Notes
|
|
|
|
- this slice does not add payment confirmation tracking yet
|
|
- current FX behavior uses the configured reminder day as the target lock date
|
|
- before the reminder day passes, the app may preview the latest available NBG rate without persisting it
|
|
- after the reminder day passes, the rate is persisted per cycle and currency pair for deterministic future statements
