To access QuickBooks remotely you can use QuickBooks Online for native cloud access, set up Remote Desktop or a VPN to your office computer, use third-party screen-sharing tools like GoToMyPC/TeamViewer or opt for a dedicated QuickBooks Hosting service that puts your Desktop version on a secure cloud server for multi-user access. The best method depends on whether you use Desktop or Online, need multi-user access and prefer a simple login or a full server environment.
