I recommended this product to a client the other day. They need to upgrade from QuickBooks (QB) Pro 2009. Everything was fine with their older version of QuickBooks, it was just that QuickBooks seemed to no longer support the QB pro 2009 with updates. Also, we were looking at adding QuickBooks Payroll and some other add ons.
The update and transfer of data from the older QuickBooks to the new QuickBooks Pro 2013 was seamless. We did not have any issues and all of the data reconciled out. One recommendation that I do have is write down you bank balance, accounts receivable number, and accounts payable number and verify that after the update the numbers are the same. I know that with this kind of technology you should not have to do that but the old school accountant in my still wants to verify a few numbers!
Anyway, I would recommend this to a small business that needs goods accounting records and has a few employees. This software can handle it! I have one client that has gross sales of $5,000,000 and 15 employees and QuickBooks Pro 2013 does everything they need, from accounting, invoicing, payroll, credit card processing, accounts payable and inventory tracking.
