I like that we have been able to easily integrate with our accounting software (QuickBooks) as well using Quickbooks Online for invoicing clients directly from within Xero! We are still working out how best this will work but so far its super easy - very simple setup process once integration has occurred between both systems.- no issues- great productGreat solution if looking at an integrated system of keeping track all financial transactions in one place without having multiple applications installed or running simultaneously through each application's own interface etc..
