Understanding Exchange Rates

How multi-currency support works in VasBox.

VasBox supports multi-currency transactions, which is essential for businesses in Zimbabwe that operate with both USD and ZWL. Exchange rates determine how amounts are converted between currencies.

Base Currency

USD (US Dollar) is typically used as the base currency. All exchange rates are relative to USD.

Local Currency

ZWL (Zimbabwe Dollar) rates are set based on the current market rate or official rate.

Adding a New Rate

How to add a new exchange rate.

Click Add Rate

From the Exchange Rates page, click the "Add Rate" button.

Select Currency Pair

Choose the currency pair (e.g., USD/ZWL). The first currency is the base (1 unit), and the second is what you're converting to.

Enter Exchange Rate

Enter the exchange rate. For example, if 1 USD = 25,000 ZWL, enter 25000.

Set Effective Date

Choose when this rate should take effect. You can set future dates for planned rate changes.

Add Notes (Optional)

Add any notes about this rate, such as the source (official rate, parallel market, etc.).

Save

Click "Save" to add the rate. It will be used for transactions from the effective date.

Rate Precision

Exchange rates can have up to 4 decimal places for precise calculations. The rate is always expressed as how many units of the second currency equal 1 unit of the first currency.

Historical Transactions

Changing an exchange rate does not retroactively affect transactions that already used the old rate. Past transactions preserve their original amounts.

VasBox keeps a history of all exchange rate changes for auditing and reference purposes.
