A company that sells in more than one country ends up with revenue in more than one currency. Finance wants one reporting currency. Product teams often want to see the amount the customer actually paid. An analytics engineer has to serve both without letting the two views drift apart.

## Keep the original amount

Store the transaction amount and its currency code exactly as the source system recorded them. Do not overwrite the original value with a converted one. Once the source amount is gone, nobody can check a conversion, fix a bad rate, or change the reporting currency later.

## Pick a rate source and stick to it

Exchange rates come from many places. A payment processor, a bank feed and a public reference rate can all disagree a little. Pick one source, document it, and load it into its own table with one row per currency pair per day. Finance usually has an opinion here, so ask them before you choose.

## Decide which date the rate belongs to

The same order can be converted at the rate on the order date, the payment date, or the date the money settled. Each choice gives a slightly different number. Write the rule down in the model description and apply it in one place. When two dashboards use two different dates, the totals will never match and people will stop trusting both.

## Handle missing days

Rate feeds often skip weekends and holidays. A simple fix is to carry the last known rate forward until a new one appears. Build that fill step into the rate model itself so every downstream join gets a rate for every day.

## Convert once, in a shared model

Do the conversion in one intermediate model that joins transactions to the daily rate table. Output both the original amount and the converted amount, plus the rate that was used. Marts and dashboards then select the column they need instead of repeating the math.

## Test the edges

Add tests that flag transactions with no matching rate, currency codes that are not in the rate table, and converted amounts that are null when the source amount is not. These checks catch new markets and new currencies before they quietly drop out of a revenue report.

## Where this work shows up in hiring

Teams that care about this kind of detail often sit close to finance, billing or revenue reporting.
