Features you'd like to see in BitVendor?

[CryptoFreak33]

Hi Everyone,

So I've got the basic code written for BitVendor and am now starting to implement all of the features and functions. So far, I've got inventory, reporting, the ability to accept cash and Bitcoin, and dynamic instant conversion of local currency prices into Btc.

What else should I include? What would you like to see in a good Bitcoin cash register program?
