I see several things...
1. Businesses are not empowered the IT system of groupon should take the grudge work out of tracking groupon deals, educating those who get a groupon offer for business, etc. 2. The group IT system should empower the sales staff to be as flexible as possible in groupon deal runs.
I see is a combination of IT improvements and realizing that you are educating 3 or more distinct group s at once and the IT system has empower that approach.
Whoever, does that will at some point reach the efficiencies Groupon needs to reach to reach profitability as being more effective will all 3 groups means less salesperson time per salesperson per group.
