Xero, QuickBooks or MYOB Sync

DO NOT USE, I installed this app and it didn't work, it would send me emails , I would log on but everything appeared fine. When I contacted support to have the historic transaction uploaded (it was 9 months that didn't work) they told me I would have to upgrade my membership ($460USD) for them to be able to do THE JOB THEY HAD BEEN PAID FOR FOR THE ENTIRE TIME.
Absolute criminals
