Data Centers
Meet Kos, the last finance hire your next campus needs.
For developers, operators and the GCs who build for them. Pay apps, GMP contracts, OFCI equipment and lender draws, checked line by line the same day.
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.

The Problem
Every draw starts with a pay app. Nobody can read them all.
Three problems data center finance teams describe, and who feels each one most.
Contractors slip line items past you
A $5M line hides in a $10B program, a forklift for the GC gets billed to you, and labor shows up at eight hours a day with zero variation.
Felt most by the CFO
Nobody can read it all in time
A 600-page pay app takes six hours before the back-and-forth starts. Review becomes spot checks, then rubber stamps.
Felt most by project accounting
You press send and hope
Hundreds of millions in draws go out every month, the bank’s deadline doesn’t move, and an electrical sub is threatening to walk.
Felt most by the pay-app lead
At Scale
Every new campus adds a desk.
One site fills one desk. Each row is one site’s month of documents. The line is the team.
The close slips. The paper triples and the team finds one more analyst. The talent pool is tiny, so site 3 waits for the weekend.
Lender draws wait on backup. The construction monitor asks for the waiver log and the stored-materials backup. Both sit in inboxes across six sites.
Overbilling is found after it is paid. No one has the hours to hold each pay application against the field report. A line billed at 71% with 58% in place is paid in full on Friday.
Illustration. One row is one site’s month of documents, and the team adds one analyst per step. At 12 sites, the line billed at 71% is pay app #14’s switchgear line.
What Finance Teams Tell Us
How do we find the 5 million dollar item that just gets snuck into a 10 billion dollar capex spend?
I just press send and I’m like, hopefully they don’t find that one.
We’re hiring so many quantity surveyors… And all they do is punch the numbers into a spreadsheet.
It’s too hard to throw bodies at. And you have the attrition and people moving into different roles. And something’s almost getting dropped.
The Solution
Kos reads them all, the day they land.
The answer to each problem above: every line item checked, every page read and every draw tied out before you press send.
Billing review
Line items stop slipping past you. Kos checks every G702/G703 line against the GMP, SOV, change orders, retainage, waivers and backup. At STACK, 85% of job spend flows through GC pay apps.

How It Works
Forward the pencil draft. Kos reads every line.
Nothing new for your team or your GCs. The pay app goes to Kos the way it goes to a colleague, and comes back reviewed the same day.
Forward the pencil draft
Email Kos the GC’s pay app like you would a colleague, or ask it in Slack, Teams, iMessage or on a call.
Kos reads every page
The G702 and G703, the schedule of values, sub invoices, lien waivers and certified payroll, each line checked against the GMP and past pay apps.
Kos flags what doesn’t tie out
Billing ahead of the work, missing sub-tier waivers and retainage math come back with the page and clause behind them.
The draw ties out before the bank asks
A line-by-line review in your Excel format, commentary to the project executive, and the entry drafted in your ERP for your approval.
What It Catches
What Kos flags on every draw.
Each flag comes back with the page and clause behind it. What you recover is your call.
Billed ahead of the work
Percent complete on the pencil draft billed past what the field report shows in place.
Field report
Missing lien waivers
Subs and suppliers paid without the conditional waiver the GMP requires.
Lien waivers
Retainage math
Retainage held below the GMP’s rate, or released before substantial completion.
Retainage
Stored materials without backup
Equipment billed as stored with no bill of sale, insurance or location.
Stored materials
Wrong entity
Bills coded to the wrong campus LLC instead of the entity that owns the PO.
Entity
Milestones billed early
Long-lead equipment billed before factory acceptance, or a deposit invoiced twice.
Milestones
In Your ERP
Forward the invoice. Kos works it in your ERP.
Kos works inside your ERP with its own login, like a new hire, whether that’s NetSuite or another system. Nothing to install, and nothing posts until your team approves it.
The invoice lands in the AP inbox
Calder Power emails INV-7309 to the AP inbox, where Kos has its own address. Or forward it to Kos as you would to a colleague.
Kos matches the PO and receipt
Kos opens PO-4512 and its receipt in your ERP and ties the invoice to milestone M3, backed by the signed factory test report.
Kos codes it and flags the freight
Ashburn Phase 2, cost code 26-1100, GL 1610. The $4,860 freight line isn’t on the PO, so Kos flags it and recommends $486,000.
Drafted for your approval
The bill waits as pending approval with the flag noted. Nothing posts until someone on your team approves it.
Not New Software
Kos exists where your team already works.
Kos has its own email address and accounts, like anyone you hire. Forward it a pay app, ask it about an OFCI invoice in Slack, text it about the draw or bring it into a call. Nothing to install.
Invite Kos to a Zoom, Google Meet or Teams call and share your screen. Show it how you check an OFCI invoice once, and it checks the next one the same way.
Instead Of
More hands, more tools, or one hire.

Outcome
With Kos on the team, every draw goes out checked.
Kos reads every pay app, invoice and waiver, and your team approves what goes out.
Nothing slips through
Every pay app, invoice and waiver gets a full read, so switchgear billed ahead of the work or a sub-tier supplier’s missing lien waiver is held before the draw, not found at audit.
Same-day reviews, partners paid on time
Each pencil draft comes back reviewed the day it lands, so the draw ties out before the lender asks. GCs and suppliers get paid on time, and the best subs want your next campus.
Hired, not implemented
Kos works in your email, Slack and calls like anyone on your team. Ask it at 11pm where electrical stands against the GMP, and it answers with the page behind the number.
You Stay in Control
Kos does the reading. You make the call.
- A human approves before anything posts.
- Every flag shows its page and clause, so your team can check any finding.
- Kos has its own identity, only the access you give it, and a full audit log.
- Your data stays in your systems.
Who It’s For
Built for the teams behind the campus.
For the companies that build, own and run data center campuses, and the finance teams inside them.
Developers
Capital has to go out on budget and every lender draw has to close on time. Kos reviews each GC pay app against the GMP before the draw.
For the CFO and project accounting
Operators
Every megawatt is already sold, so the footprint outgrows the team. Kos reviews expansion pay apps and vendor invoices across sites and entities.
For finance across sites
General contractors
Kos checks your subs’ pay apps, lien waivers and certified payroll before they roll into your own G702 and G703.
For the pay-app lead
Questions, answered.
Kos reads every page of the pay app, not a sample, and shows the page and contract clause behind every flag.
Nothing posts until someone on your team approves it. When Kos is unsure about a line, it asks instead of guessing.
There’s nothing to implement. Kos gets a login like a new hire, and your team emails it the pay apps.
Kos reads your contract and fills out your draw workbook in your columns. Show it your process once on a screenshare.
Kos works inside your systems under its own identity, with only the access you grant, and every action is logged.
No. They keep sending pay apps and invoices to the same inbox.
An analyst takes months to find and covers a few sites. Kos covers every site on every campus from the day it starts, to the same standard.
Why Now
The buildout won’t wait for your next hire.
Data center construction is up 73% in a year.
Up from $49B a year earlier. Every dollar of it arrives as a pay app your team has to read before the lender funds the draw.
