Earlier versions of QuickBooks let you sign up for a service to store your documents online. Starting with QuickBooks 2012, you can store documents locally on your computer and attach them to QuickBooks records.
With local storage on your computer:
Storing documents is free
Documents are stored on your computer
You don't need an Internet connection to attach or view local documents
You use QuickBooks to add documents from your computer or scanner, and you attach them to records from within QuickBooks
You can't share documents with customers or vendors, or access them online
The Doc Center within QuickBooks is where you can manage your documents. If you have an existing online subscription, you can still access your documents online.
