I have been using this app for about 2 years now and love it. My CPA uses quickbooks, since I am not a real accounting person I chose to use InvoiceASAP because it is so much simpler and easy for me to make changes on the fly. Now I just started the sync service so it automatically syncs with quickbooks. I saw in a previous review that a person complained about paying a few dollars per month for the service. My response is that you get what you pay for and nobody will work for free. I pay less than 100.00/year and the small expense is well worth it to me.
Thank you Invoice ASAP.
