Hi Neil,
After consideration with the development team it was decided that such functionality should be included within a CRM system and not a bookkeeping software. We would therefore recommend using a trusted integration such as salesforce or ZohoCRM to allow this?
Agree with Ken. KashFlow's product owner seems more interested in finding excuses then to actually providing value for customers.
Can't see why this would not be implemented. It's on Sage, Quickbooks and Xero and would be very straighforward technically.
