You found the savings. Now go get it signed off.

Running the numbers is the easy part. This builds the document that says what it's costing, what we're asking for, and what it returns, so you're not starting from a blank page in front of finance, security, or procurement.

Reserver internal business case

Reserved Instance coverage: the numbers to send upstairs

Sized for dozens of reservations · a few accounts. Usually signed off by a platform or DevOps lead, with a finance counterpart on the monthly line item.

The situation

The gap between reviews. Coverage drifts in the weeks after a quarterly review closes. New instances launch, old reservations expire, and nothing catches the difference until the next cycle.
The renewal that slips a few days. Even disciplined teams miss a renewal date by days here and there, and each slip bills the gap at on-demand rates until someone repurchases.
The purchasing habit that outlived its logic. A buying pattern gets set early and never gets re-derived from what the fleet actually looks like now.

What it's costing

$105,300estimated annual leak from unmanaged reservations, across this whole fleet

$951one renewal slipping 14 days, at this fleet's blended rate

Zoom in on one instance: at AWS's published reserved-vs-on-demand spread for a larger database class, a single unreserved instance left running 14 days past its term bleeds about $188 on its own. The figure above is a blended average across every reservation a fleet this size carries, not one instance.

What we're asking for

Autopilot is a flat monthly line item, never a cut of what it saves. Here's what it costs against what it returns.

What it returns

One prevented missed renewal alone pays for about 6 months of Reserver.

How we know

Conservative and disclosed as estimates, not a quote: 65% of typical compute spend is reservable capacity, discounted at a blended 45%. That's below the higher published ceilings for any single term, since this blends across a whole fleet. Reserver shows the exact math, per reservation, once you connect an account.

Before they ask

The questions finance, security, and procurement raise.

We already have a FinOps team and a vendor for this: why add another tool?

Most FinOps tools and vendors work account by account. The money hides in the seams between accounts and teams. See the case study below, where every account looked fine alone until one coverage view spanned all of them. Reserver is that view.

Does pricing scale with our savings, like some vendors charge?

No. Flat software pricing, never a percentage of what you save. A vendor that takes a cut of your savings profits most when your bill was worst. Scale is a flat $499 a month, or $4,990 billed once a year, for every account you connect; if procurement needs a custom agreement, MSA, or SLA on top of that, Enterprise covers it.

We already review our reservations every quarter in a spreadsheet: why do we need this?

The real leak sits in the months between quarterly reviews, not in the review itself. The account in the case study below had over a decade of reservation discipline and still leaked real money in exactly that gap. Autopilot closes it continuously instead of every quarter.

Can something buy a reservation without our sign-off?

Only if you set it up that way. Watch-only mode never buys anything. On Autopilot, every rule can require an approval step before a purchase executes, and every purchase, manual or automatic, is logged with who, what, and when.

Are you SOC 2 or ISO 27001 certified?

Not yet. Reserver is pre-launch. Formal certifications are on the roadmap; we'd rather say that plainly than claim something we can't back up.

How do you access our AWS accounts? Do you store credentials?

Cross-account access is assume-role only, using the role you created and can revoke. We never see or store your AWS access keys.
