Answer depends on who you are - are you a company or a (business) travel agent? Do not quite understand what you mean by "hold to contract and fees" - perhaps you could expand the question a little and one will try to reply!
You still need to have a revenue stream, there are various ways of doing this though at the end of the day, they more or less boil down to the sme thing. The airlines will not pay you, you can't do everything on Cat35 fares (or similar) so you have to dress it up one way or the other. Over the years, pretty much all methods have been tried - I would be very surprised if the "unique" travel scheme, is that unique, after all.
Saving money has naff all to do with travel agents and fees; it has nothing to do with booking a later flight or an earlier flight, nor does it have anything to do with people in an organisation all only flying economy, nor does it have anything to to do with self booking tools, or having a special (or unique) arrangement, nor being with a big or a small agency. You have to take a step back. The fact of the matter is, that once a traveller calls a travel agent or prepares to make an online booking 99.9% of all opportunities to save money have already been lost.
This, I realised a while ago and so now, with my clients, I have to educate them. For the client, there is real and substantial saving in the way this is done. Start from this maxim (I don't want to give away all my thinking!) : "The quickest and most efficient way to save money on travel, is not to travel in the first place".
