Bookkeeping software have a lot of add-on apps that make your life easier. Depending on your needs and what you are trying to do will depend on what apps will be best for your business.
Right now the app I am working with and loving the most is Hubdoc. Hubdoc is AWESOME. It allows you to do a few different things. One thing you can use it for is it will auto fetch any statements from your bank or other bills you have online like cable, internet, utilities, etc. I have not used this feature because the banks my clients use are not available but the people I know that have used this really like this feature.
The main thing I use it for is for capturing receipts. I scan my receipts using Scan Cloud. With Scan Cloud you have several options you can use for where the scans go. Some of the options are Dropbox, google drive, etc. But Hubdoc is also another option.
I set all the scans to go to my Hubdoc account. After I do that I wait like 1-2 days for Hubdoc to do it’s thing. In the background Hubdoc will read all your receipts. They pull the vendor and amounts out. In Hubdoc you go in and create the receipt, categorize it, and then send it right over to your bookkeeping program with the receipt as an attachment.
Here is a video of how it works.
