QuickBooks Online provides business owners with a convenient remote access option. You, your auditors or your accountant can log in to your QuickBooks account from any web browser which gives you access to information on the go and enter bills anytime.
While importing bills is currently unavailable in QuickBooks Online US, you may search for third-party applications that integrate well and provide seamless importing of bills. Though, we're unable to provide recommendations on which one to use.
I suggest you visit the QuickBooks Apps site and look for an app that meets your business needs. You can also do this inside your company, just go to Apps on the left panel and then enter a keyword in the search field.
