XERO Order & Inventory Sync

Useless, this app only imports certain orders, spoke with support over a number of days only to be told that they know it doesn't work, they don't know why, can't offer a work around or give us any idea on how this can be managed. No idea which invoices will be imported and which will be left behind. They also say they can not give me a time frame on when the bug will be fixed. Currently looking for alternatives. Avoid.
