A MACC, the Microsoft Azure Consumption Commitment, is a contractual promise to spend a set total on eligible Azure and Microsoft commercial marketplace services over a multi year term, in exchange for the discounting and enterprise terms that come with committing. The shortfall clause is the part that bites: if your eligible consumption over the term comes in below the committed total, you are liable for the unspent balance anyway. In other words, the MACC sets a floor on what you will pay, not just a target. Commit to spend a given amount over three years, use less than that, and Microsoft can invoice the shortfall at the end. That is why a MACC is never free money for committing; it is an obligation that rewards an accurate forecast and punishes an inflated one.
Here is exactly how the clause works, what counts toward burning it down, and the buyer side discipline that keeps a MACC from becoming a bill for spend you never made.
What does the MACC shortfall clause actually say?
The mechanics are use it or lose it with a twist: you do not merely forfeit a discount if you underspend, you owe the gap. The commitment is a total dollar figure over the term, and eligible consumption draws it down as you spend. At the end of the term, if cumulative eligible spend is below the commitment, the remaining balance is payable. This is structurally different from a Reservation or an Azure Savings Plan, which discount specific usage and where the worst case is simply lower utilization of the discount. With a MACC the worst case is paying for consumption that never happened, which makes the sizing of the commitment the single most important decision in the deal.
What spend counts toward burning down a MACC?
More counts than most buyers assume, and counting it all is the first line of defence. Eligible Azure consumption draws down the commitment, and crucially so does a wide range of eligible third party software purchased through the Microsoft commercial marketplace, because that spend flows through the same agreement. Many enterprises run below their MACC drawdown not because they lack the consumption but because eligible marketplace purchases, software they were buying anyway, were routed outside the agreement and never counted. The discipline is to channel every eligible purchase through the marketplace so it contributes to the commitment. We cover this lever in marketplace spend and commitment drawdown.
How do you size a MACC so the shortfall never bites?
Size to a forecast you can defend, not to the optimistic plan that wins the largest discount today. Separate the consumption you are confident will happen, the steady run rate plus migrations that are already funded and scheduled, from the growth you hope for but cannot guarantee. Commit to the floor you are sure of, and treat speculative growth as upside that earns better terms at the next renewal rather than as a number you sign up to pay for now. A smaller commitment you will comfortably exceed is worth more than a larger one you might miss, because the larger one carries the shortfall risk. The discount on a slightly smaller MACC is almost always cheaper than the penalty on a missed larger one.
How do you manage drawdown across the term?
A MACC is not a set and forget commitment. Track cumulative eligible spend against the straight line you need to hit the total, every month, and treat a persistent gap as an early warning, not a year three problem. If consumption is running behind, you have levers while there is still term left: route more eligible spend through the marketplace, accelerate planned migrations, and, if the trajectory is structurally short, open the renewal conversation early from a position of information rather than waiting for the shortfall invoice. The buyers who get bitten are the ones who discover the gap at term end. The ones who do not are watching the drawdown the whole way and acting on it.
Where MACC fits the wider commitment strategy
The MACC sits on top of your Reservations and Azure Savings Plan coverage, and it interacts with how you negotiate the whole Microsoft relationship. Understand the full picture in the cloud commitment negotiation guide, know your options when a commitment shortfall looms, and make sure the contract terms protect the buyer before you sign. A MACC is leverage when it is sized right and a liability when it is not.
