The Accounting section of the Configuration area enables you to control:

• Your Accounting Periods, which are important when creating Transaction Documents, Reports, Quotas and Forecasts;
• Your Own Organisation information;
• Any Exchange Rates between your Home Currency and other currencies used by any of your Own Organisations;
• The Tax Regime(s) that apply to your Own Organisations, including setting the Sales Tax Codes that form part of that Tax Regime.

You can also see a list of the System Currencies supported by Workbooks.  If the one you're looking for doesn't exist, please contact Workbooks Support.
