To set your base currency, navigate to Settings > Currency
Your base currency is the main currency that your business transacts in, for example if all your sales and accounts are done in Hong Kong Dollars, your base currency will be HKD. Please note, you can still showcase different currencies on your storefront, this is simply the currency that all your sales will be reported in.
To set your base currency, simply select the currency from the dropdown on the page.
After setting the base Currency, you will have the ability to enter a percentage markup or markdown (with a negative number e.g. -0.50) to reflect changes in foreign currency when chosen. This will help create rounded figures (e.g. €58.00 instead of €57.89), presented on the front end website.
