Business Settings
If you've just created your business, click on Business Settings, and start by giving the business a name.
If the business is VAT registered, further options are available as described in Setting Up VAT. The app can manage VAT and keeps track of sales and purchase VAT separately. It also splits VAT by category.
If the Customer Invoicing add-on is enabled, there are further options available to set the business address, logo and footer for all invoices and statements.
The Delete Business at the bottom of the basic settings list is used to delete all the business information, including its transactions (invoices, transfers and so on). There is no way to recover this information other than restoring from the backup file so be careful!
