It only takes up a little room to have QuickBooks installed. However, as the firm grows, the data from your transactions and operations will take up more and more space. Only 2.5GB of storage capacity on storage discs is needed. It should be good to have at least 256 GB as long as a business doesn't scale up to performing thousands of payments each day. However, you won't have to worry about storage if you choose the cloud version. This version's data is stored in the cloud, where it can only be accessed by you using your QuickBooks accounts.
