This article was created for potential users who would like to use Method CRM with international versions of QuickBooks Online.

Resolution

The Intuit Developer Group (IDG), which is used by third-party developers to create apps for QuickBooks Online (QBO), supports apps for some of the international versions of QBO. 

As such, Method CRM will support and sync with international version of QBO for USA, Canada and Australia with all editions supported. UK and other international version of QBO are not yet supported by Method CRM.
