One law governs money everywhere in BlossomERP: every amount is denominated in the currency it belongs to, and the screen says so. There are no bare numbers that you must guess the currency of.
- On a document written in a foreign currency, every total, price, and balance is in that document's currency, and money fields show the currency as you type. Your company's own reports convert to your default currency behind the scenes; the document itself never mixes the two.
- A price may be set directly in the foreign currency, or taken from your home-currency catalogue and converted at the document's exchange rate. A rate is frozen when the document posts, so a posted invoice's figures are the same next year as today.
- If no exchange rate is available, the application leaves the rate blank or stops and tells you — it never invents a rate and never quietly reuses yesterday's. A missing rate is a small, visible task, not a hidden error inside your books.
See 7.11 Exchange rates — frozen rates, conversions, and FX gains and losses for how gains and losses surface when foreign money settles.
