“U.S. Army Engineering Support Center, Huntsville, has selected the Company for a multiple-award, five-year, $XXX million indefinite delivery, indefinite quantity contract”
Saw this today, “indefinite delivery, indefinite quantity contract”. No schedule defined, No quantity of deliverables defined. So what they are saying is "Send us some stuff when you get around to it.
Shhh,
To us, it’s on a, “NO NEED TO KNOW” basis. TOP SECRET-CONFIDENTUAL Government Business. Government telling us, "Mind you’re own business! 
Like Bruce26 says 
Just PAY YOUR TAXES!!! 
'Fraid that is not really what happens. As an AF Comptroller (money guy), with a government contracting course under my belt, I have worked with IDIQ contracts. What that really means is, “be ready to send us the items when we order them, on the schedule we provide when we order.” It is a way to have an open contract against which individual delivery orders can be made, without having to go through the full bid solicitation, review, selection, and purchase order steps every time you need more of that item. This actually both saves time and money; not only does it prevent the long bid process from repeating, it also prevents over-ordering to have some on hand, “just in case” we might need them later.
@Craig_AR U R The Man. Thanks for educating me/us. When I read these kinds of statements in corporate statements I cringe. They “sound” like an awful deal when, as you’ve pointed out, they really may be the right way to do things.
Hmmm… I still remember the “hammer and toilet seat” fiasco. 
@BRUCE26 Not to mention EMBEZALMENT, FRAUDULANT TRANSACTIONS, DEALINGS GOING ON UNDER THE TABLE within the ranks Don’t say any thing to Craig_AR! you too, Mike164
I forgot to give a specific example. Back in the 80’s the AF used IDIQ contracts for personal computers (anyone remember the Zenith Z-100?). Under the IDIQ, each AF base could order as many as they needed, using locally budgeted money, to be sent out directly to the location that needed them. Better than a massive purchase to a big warehouse, to hang round until a location asked for some. Same deal on an IDIQ for electric typewriters.
Ain’t that nice. In theory they could only make and deliver 1 round a year and meet the contract. Don’t mind me, I’m a conspiracy theorist.
