Administrative Analytics to see how company staff and logins are performing

Just some simple information by login (for an administrator) to determine how many invoices have been entered, checks written, achs sent etc over a particular period. By month is ideal. It would add insight for how many employees you might have to add if you take on a new client, and it might provide additional insight if one employee entering bills is lagging behind another. This is extremely important and does not have to be pretty. Just a basic output by Login would be ideal.
