Downloading QuickBooks is very helpful. QuickBooks is available for download for both home and business systems. But only one person should own those. You can do that by getting a single-user license.
Further, you can set up QuickBooks on two PCs, thanks to this. However, in accordance with the terms, you are only permitted to operate one installation at a time while using each system independently. Yet, if you buy a different version of QuickBooks, like QuickBooks Enterprise, you can use it on more than two computers
