To make changes to how your business information appears on invoices, estimates and bills, please navigate to Business Settings > Edit Business Information. On the following page you'll be able to edit the business details, such as the type of your business (organization or individual), your business name and address, business phone number, Tax Identification Number, custom invoice fields, notes and more.
Custom fields are used to display customized information about your business on invoices, estimates and bills. A custom field pair always consists of a key (e.g. "Company Register Number") and a value (e.g. "12345"). Custom field pairs will be displayed on statements below your company address.
