← SaaS Seat True-Up Calculator
Zylo is a well-known enterprise SaaS spend management platform, described on zylo.com as continuous discovery and control over an organization's software portfolio. It works by connecting to financial systems — ERP, accounts payable, and expense platforms — and to SSO providers, so it can find every SaaS application an organization is paying for, not just the ones someone remembers to list. Pricing is by quote rather than published on the site, and buying it means becoming a customer of an ongoing platform, not opening a page.
That makes Zylo the right choice for one job: continuously discovering and governing an entire, possibly unknown, SaaS portfolio across an organization. This page does not do that job, and does not try to. It has no integrations, connects to nothing, and does not discover anything — it takes the numbers you already have for one renewal and turns them into an avoidable-spend figure.
| Question | Where to answer it |
|---|---|
| What SaaS tools is my organization even paying for? | Zylo or a comparable discovery platform — that requires connecting financial and SSO data this page never sees. |
| How many of the seats on this one renewal I already have a quote for are unused? | This calculator — type purchased seats, seats used, price, and months left; get the avoidable spend in seconds, no signup. |
| Do I need ongoing, cross-portfolio spend governance and renewal alerts for every app in the company? | Zylo or a comparable platform — this page remembers nothing between renewals and tracks nothing across tools. |
| Is this quoted overage premium going to cost more than staying at the purchased seat count? | This calculator's overage field, next to the same renewal numbers. |
This calculator is deliberately the opposite shape from a spend management platform: nothing to connect, nothing billed monthly, and nothing you type ever leaves your browser. That makes it useful for a single upcoming renewal you already have numbers for, and the wrong tool for finding SaaS spend you do not already know about across an entire organization — that is exactly the job a platform like Zylo is built for.
It needs no account, no integration, and no sign-in: it is a static page, the arithmetic runs in your browser, and once it has loaded it keeps working with the connection off.
They answer different questions. Zylo is a paid, ongoing enterprise platform built to discover your organization's entire SaaS portfolio by connecting to financial systems (ERP, accounts payable, expense) and SSO providers, then track spend and utilization across every application it finds — described on Zylo's own site at zylo.com. That is a data-integration project: connecting live feeds, standing up a system of record, and paying for it on an ongoing quoted contract. This page does not do that job, and does not try to. It has no integrations, discovers nothing on its own, and does not know your SaaS portfolio exists. What it does is take the one renewal you already have in front of you — purchased seats, seats actually used, price, months left — and turn it into an avoidable-spend figure in your browser, right now, with no signup and nothing connected.
No. This site is not affiliated with, endorsed by, or sponsored by Zylo. Zylo is named here only to describe what this calculator is and is not, based on Zylo's own public site.
