I had some issues getting version 1.3.3 of the Contact-Form-7: 3rd-Party Integration plugin to work with the BNTouch CRM app. Support from Zaus was pretty exceptional and he got it working fast.
My ContactForm7 has 17 fields that post directly to the CRM. CF7 also sends the data in two emails to key staff.
I know a lot of web builders like myself use Gravity Forms for more complex situations, but in this case, CF7 and the 3rd Party Integration plugin worked great - even with an obscure CRM like BNTouch.
