We'll start things off with General global settings, which can be accessed by hovering you mouse over the Settings button in the top right corner of the screen and after that selecting the Global information settings option that shows up in a pop-up down below. The type of settings that you can tweak here will affect entire Introbills. This includes things like interface language, currency, decimal and thousands separator. After changing the currency, only new invoices created after the currency change will have the new currency. Existing invoices will have their old currency. After changes first click Save and then either Print preview or E-mail preview to see a preview of the changes you made in a pop-up. Keep in mind that 2 different invoice layouts are generated by Introbills. 1 for invoices sent via email and then another one for invoices created for print.
