Reading the AWS EDP Addendum Line by Line

Start by reading the AWS EDP addendum line by line

The discount you were sold lives in a slide. The deal you actually sign lives in the addendum. Reading the AWS EDP addendum line by line is the single highest value hour in the whole process, because every number that matters, the committed amount, the discount tiers, the term, the eligible services, and the shortfall mechanics, is fixed there in language that will not move once your signature is on it. As of June 2026, the AWS Enterprise Discount Program, also referred to as a Private Pricing Agreement, is a spend commitment over a one to five year term that unlocks tiered discounts scaling with the committed amount (source: AWS Enterprise Discount Program terms, as of June 2026).

The addendum is short. That is the trap. A two page document decides whether you save money or carry a liability for three years. Sellers count on buyers skimming it, signing under a quarter end deadline, and discovering the carve outs later. Below is how an independent buyer side negotiator reads it, clause by clause, and what each line is really telling you.

The committed amount and the term

The first number is the commitment. It is a floor, not a budget. You are promising to spend at least this much eligible spend over the term, and if you do not, you pay the difference as a shortfall. Read the exact dollar figure, the start date, and whether the commitment is annual or cumulative across the term. A cumulative commitment with an aggressive back loaded ramp can look easy in year one and become a cliff in year three.

What to check

• The committed amount per year, written out, not just a total.
• Whether unused commitment in an early year can be applied to a later year, or whether each year stands alone.
• The exact term length and the start trigger, signature date or first invoice.
• Any automatic renewal language, which removes your single biggest future leverage point.

Overcommitment is the recurring buyer risk here. If the committed amount exceeds your real consumption curve, the addendum has quietly priced in a penalty you will pay later. We rebuild the number from actual usage before it is signed.

The discount schedule and how it tiers

The discount is rarely a single flat percentage. It tiers with the committed amount, and the higher tiers often require spend levels you have no plan to reach. Read whether the discount applies to all eligible spend or only to spend above a threshold. Read whether the rate steps up as you cross tiers or whether you were quoted the top tier rate on a commitment that only earns the bottom tier.

Discounts typically become available from around one million dollars of annual spend, with dedicated account attention usually arriving nearer five million dollars (source: AWS EDP program structure, as of June 2026). The EDP discount stacks on top of Reserved Instances and Savings Plans, so confirm the addendum states clearly how the EDP rate applies before or after those existing savings. Stacking order changes the effective discount materially.

Eligible spend, exclusions, and the services that do not count

This is where the headline discount leaks. The addendum defines eligible spend, and anything outside that definition still costs you list price while doing nothing to satisfy your commitment. Marketplace inclusion is negotiable, and whether third party Marketplace purchases count toward the committed amount can swing the math by millions. Read the exclusion list slowly. Credits, taxes, support charges, and certain services are commonly carved out.

If a large slice of your spend sits in an excluded category, your effective discount is lower than the number on the slide and your commitment is harder to reach. Map your real bill against the eligibility definition before you agree to the committed amount. Our guide on Negotiating EDP service exclusions and carve outs covers how to push these definitions back in your favor.

Shortfall, true up, and what happens if you miss

Find the shortfall clause and read it twice. It tells you what you owe if your eligible spend falls below the commitment. Some agreements bill the gap at the end of each year, some at the end of the term. Some let you true up by spending more, some simply invoice the difference. Overcommitment creates a shortfall the buyer must pay, with no rollover of unused spend (source: AWS EDP terms, as of June 2026). There is no partial credit for being close.

Also read the cross account credit application language. In a multi account organization, whether the discount and the commitment apply across all linked accounts or only the payer account is a negotiable point that decides how easily you reach the number. Our explainer on How AWS EDP credit application works across linked accounts walks through this.

Support charges, credits, and the fine print

Beyond the headline clauses sit the lines most buyers skim. Support charges are often a percentage of usage and may or may not count toward eligible spend, which changes both your effective discount and your path to the commitment. Promotional credits and free tier usage usually do not count, so a bill that looks large can contain spend that does nothing for your number. Read each of these definitions and reconcile them against your real invoice, because the gap between gross spend and eligible spend is where a comfortable commitment quietly becomes a tight one.

Look also for any clause that lets the provider change list prices or service definitions during the term. The discount is a percentage off a moving target, and if the base can shift, the value of your discount can shift with it. Price protection language is negotiable, and an enterprise committing for several years should ask for it explicitly rather than assume stability.

A reading checklist before you sign

Treat the addendum like a closing document, because it is one. Work through it in a fixed order so nothing slips past under deadline pressure. The committed amount per year, the term and its start trigger, the discount schedule and tiers, the eligible spend definition and exclusions, Marketplace treatment, cross account application, the shortfall and true up mechanics, and finally any auto renewal or price change clauses.

• Is the committed amount written per year, and can I reach it from real usage?
• Does eligible spend include Marketplace and the services that make up my bill?
• Is the shortfall billed annually or at term end, and is there any rollover?
• Is auto renewal present, and have I struck it or made it optional?
• Are list price and service definitions protected for the term?

Every item on that list is a number or a right that survives your signature. An hour spent here is the cheapest leverage you will ever have on the deal.

The clauses sellers hope you skip

Two clauses deserve special attention. First, auto renewal. If the addendum renews automatically, you lose the leverage window that is greatest 6 to 9 months before expiry. Strike it or convert it to a renewal at your option. Second, any change of control or service substitution language that lets the provider alter eligible services mid term. Both are commercial terms, and both are negotiable before signature.

This is commercial negotiation guidance, not legal advice. Have your own counsel interpret the contract language. Our role is to make sure the commercial terms, the number, the discount, the exclusions, and the exit, are built on your real consumption and not the seller's forecast.
