Base Currency Rates

This page describes the Base Currency Rates setting in the System module.


The Base Currency Rates setting is only used by the Dual-Base system. After entering the Currencies used in your business using the Currency register and having defined your two Base Currencies using the Base Currency setting, you should use the Base Currency Rates setting to enter an exchange rate between the two Base Currencies.

If there is a fixed exchange rate between the two Currencies, enter a single record expressing that relationship in this setting. Otherwise, each time the exchange rate changes, you should add a new record to the setting rather than modifying an existing record. This ensures an accurate history will be created which will then be used when currency conversions are required when producing reports.

You should only use this setting for exchange rates between the two Base Currencies. Use the Exchange Rate register in the System module for all other exchange rates.

To open the Base Currency Rates setting, first use the [Switch Module] button in the Navigation Centre to change to the System module. Then, if you are using Windows or Mac OS X, click the [Settings] button in the Navigation Centre and then double-click 'Base Currency Rates' in the 'Settings' list. If you are using iOS or Android, select 'Settings' from the Tools menu (with 'wrench' icon) and tap 'Base Currency Rates' in the 'Settings' list. The 'Base Currency Rates: Browse' window will open, listing the exchange rates that you have already entered.

To enter a new Base Currency Rate record, select 'New' from the Create menu (Windows/Mac OS X) or the + menu (iOS/Android). You can also use the Ctrl-N (Windows) or ⌘-N (Mac OS X) keyboard shortcut. Alternatively, highlight a record in that list that is similar to the one you need to enter and select 'Duplicate' from the same menu.

The 'Base Currency Rate: New' window will be opened, empty if you selected [New] or containing a duplicate of the highlighted exchange rate. In the case of the duplicate, the Date of the new record will be the same as the one in the copied record.

Complete the record as appropriate and as described below the illustration, then save it using the [Save] button (Windows/Mac OS X) or by tapping √ (iOS/Android). You can then close it using the close box (Windows/Mac OS X) or by tapping < (iOS/Android). Then, close the browse window using the close box or < again.

Paste Special    Choose date
The earliest date for which the exchange rate is valid.

The current exchange rate is the one with the most recent date: this will be used as a default when you enter new transactions.

Base Currency 1, Base Currency 2
Use these two fields to specify the exchange rate, which you should enter as a ratio. In the example illustration, 0.89715 units of Base Currency 1 (GBP) will buy one of Base Currency 2 (the Euro). Note that if either Base Currency is the Euro, EMU regulations state that the ratio must always show how many units of the other Currency can be bought with one Euro.


When an exchange rate changes, always create a new record in the Base Currency Rates setting. Do not change an existing record.
