iMerchandise has 3 currency formats by Default: $, € and £
To set the desired currency, please follow:
1. From the Main Menu, Go to Settings
2. Tap on Currency Format
3. Select your Currency
After this, all prices displayed in Budgets, product listing, Purchase Orders, will have the currency you've selected.
*Note that this operation should be made after you install the app and before you start using it. The app doesn't have a currency convertor. The Set Currency function is just for display purposes. So if you create products, budgets and POs with $ and change it later to €, the actual values won't change
