Kos works in the software you already own.
It gets its own login and license seats in Excel, Word, SharePoint, Google Drive, and NetSuite. No migrations, and no new app for your team to learn.
Why Kos
A finance employee, not another finance tool.
Kos checks every bill against what was agreed, the same day it lands. You onboard it like a new hire, and it works from your email, Slack and calls like anyone on your team.
Kos reads all 812 pages of Ridge Electric’s pay app #14, ties out the distribution and generator lines, and flags switchgear billed ahead of the work, Hollis Supply’s missing lien waiver and retainage held at 2.5% where the contract keeps 5%. It recommends $754,300 of the $1,374,750 requested, drafted in NetSuite for your approval.
Procure-to-pay: Calder Power emails a milestone invoice to the AP inbox. Kos enters it as a bill in your ERP, matches it to PO-4512 and the signed factory test report, codes it, flags $4,860 of freight that isn’t on the PO, and saves the bill at $486,000, pending your approval.
Maya invites Kos to a video call and walks it through a bill on screen share, Kos asks who to tell when a bill doesn’t match the PO, then replays the workflow on a new bill in the ERP sandbox while she watches: it finds the prepayment already went out, tells the requester on Teams, and leaves the bill pending your approval.
What Kos Believes
Every dollar you pay out should be checked against what was agreed, before it’s paid, not found after.
That means the contract, the PO and the receipt, read line by line on every bill. Until now only people could do that work, and there aren’t enough of them.
So Kos was built to be the hire you can’t find: a finance employee who reads every page, works where your team already works, and leaves every call to you.
Why Now
The buildout won’t wait for your next hire.
America is in an industrial revival, and every dollar of it runs through a finance team.
Hyperscalers will spend $700B+ on capex this year.
Almost five times what they spent in 2023. Every dollar of it arrives as a bill your team has to check before the money goes out.

Factory construction has doubled since 2020.
US manufacturers are building at $171B a year. Every machine they order becomes a deposit, a payment at acceptance and a delivery months later that finance has to reconcile.

The US outspends the next six countries on defense.
That money becomes new plants, new subsidiaries and hundreds of bills a day, often on an ERP that’s less than a year old.

There are 10% fewer accountants than in 2019.
Every one of those commitments runs through a finance team that’s smaller than before the buildout began, and throwing more heads at it doesn’t work.

What CFOs Told Us
The money goes out. Nobody had time to check it.
Every bill is supposed to be checked against what was agreed. At today’s volume, most of it isn’t, and finance leaders know it.
You’re getting fleeced
Contractors and suppliers slip line items past you: a forklift for the GC, labor billed at eight hours a day. A $5M line hides in a $10B program.
Felt most by the CFO
You press send and hope
The deadline doesn’t move and a contractor is threatening to walk, so you sign off on what you couldn’t check.
Felt most by the pay-app lead
You can’t hire your way out
Experienced finance people are scarce and slow to hire. Consultants bill by the hour, and the next site still needs another desk.
What Kos Does
Three jobs your team does by hand today.
Kos checks each one against what was agreed: the contract, the PO, the receipt. Nothing posts until your team approves it.
Billing review
Kos reads every page of every bill, from pay apps to progress invoices, checks each line against the contract and prior bills, and cites the page and clause on every flag.
Learn more: Billing reviewProcure-to-pay
Kos enters bills in your ERP, works three-way-match exceptions and codes against vendor history. At Saronic that takes 3 minutes a bill, across 4,000+ bills a month.

How You Hire Kos
Onboarded like a new hire, not rolled out like software.
Give Kos the access your team already has, and its first review comes back the same day.
The same access as your team
Kos gets its own login to the shared drive and the software your team already uses, like NetSuite. There’s no implementation project and nothing to migrate.
Its first review, the same day
Forward Kos a bill the day it starts, and the review comes back that day, every flag cited to page and clause and waiting for your approval.
Teach it as you go
Show it a new workflow on a screenshare whenever you need one. It asks questions, each answer becomes a rule, and nothing posts until your team approves it.
Hired, Not Implemented
Kos works like a colleague, in the software you already own.
No migration and no new app for your team to learn. Kos signs in with its own login and only the access you grant.
Kos has its own identity and a full audit log.
Role-based access tied to its identity, every action it takes logged, and you own your data.
- SOC 2 Type I
- SOC 2 Type II
Your controls, on every site.
Teach Kos your gold-standard controls once, over screenshare. It asks questions, replays the work on a new task, then runs it the same way on every site.
What It Means

Who It’s For
Built for the whole finance team.

The controller
Bills post right the first time and the backlog clears without new hires. Kos works across sites and entities and drafts every bill for approval.
Champions it
AP and project accounting

Questions, answered.
Automation software runs the rules you set up and stops at the exceptions. Kos reads the whole bill and the documents behind it, works the exceptions the way an accountant would, and asks when it isn’t sure. There’s no app for your team to learn.
No. Kos takes the reading, matching and backup-chasing off their plate. Your team approves what goes out and makes every call.
Nothing posts until someone on your team approves it. When Kos is unsure, it asks instead of guessing.
An analyst takes months to find and covers a few sites. Kos covers every site from the day it starts, to the same standard.
No. Kos flags the dollars and shows the page and clause behind each one. Recovering them is your call.
The same day. Give Kos access to the same shared drive and software your team uses, like NetSuite, and forward it a bill. There’s no implementation project or pilot phase to wait through.
Kos works inside your systems under its own identity, with only the access you grant, and every action is logged.
Make Kos your last finance hire.
No new software to learn. Email Kos the work and watch it run.
