Personally I like the campaign function. This enables us to create a tailored campaign based upon live data on a day by day basis.
I also like the design and ease of use, especially how it highlights area's of opportunity with our customers.
The inbuilt CRM and facilities this offers are extremely useful with an opportunities tab to highlight wins for later dates.
Finally.... The mapping tool is extremely useful for helping our reps plant their route for the day/future days ahead!
I don't really have any areas that I dislike.
If you are looking for a sales analysis system with an inbuilt CRM, you don't really need to look much further than this!
It will genuinely help get into understanding the gaps, highlight trends and more importantly get your sales team working so much more efficiently.
The automation side of reports (Campaigns) is another of the most useful features driving information direct to the reps. It will make them more inquisitive!
In the main I'm looking at is sales gaps. The benefit gained from using sales-I is already starting to pay dividends.
I run a reports once or twice a day to highlight gaps, this data is fed to our reps for proactive work by either them or my team in the office. It's easy to do, with the click of a mouse. The main feature loved by all our reps is the "drill down". In laymans terms, you can look at a specific product group, then drill into that by the rep, then from there drill into the accounts and carry this through into the specific products bought
