Integration is our 'thing' and therefore the more integration that we have to other things the more that point is re-enforced. We have been asked several times in New-Business about the possibility of integrating to someone like Credit Safe (who apparently have a really good API) - a field for holding company reg number, & then a button / tab to load up Credit Safe information about the company would be ideal.
This is specifically for a Sales function, we always check who the listed directors are for a company that we are trying to sell to - so that we know who the decision maker actually are. At the moment this is a manual and time consuming part of the sales process, where integration would make perfect sense.
