Yes, we’ve done it. By popular request, the ‘official’ app for QuickBooks integration is out and available to all users, paid or free. This is the first iteration of the app and it syncs information for contacts, companies or accounts between your Bitrix24 and QuickBooks accounts. This is very convenient if you are issuing invoices from QuickBooks, rather than Bitrix24 for example. You will also get notification inside your Bitrix24 account when QuickBooks-issued invoices are paid by the client.
If you have a desktop version of QuickBooks, please use this app instead.
