The Situation
Gigawatt campuses, a finance team still hiring.
Montera owns what it builds: a 500 MW campus in Glendale and a gigawatt campus outside Houston, with Stonepeak’s $1.5B behind them. Every GC pay app had to be validated against earned progress and the schedule of values, and every long-lead equipment bill against its PO, by a finance team still hiring its first accountants.

How Kos Works It
Pay apps and equipment bills, read line by line.
The GC’s pencil draft is forwarded to Kos.
Like it would be to a colleague. Kos reads every page: the G702 and G703, the sub invoices, lien waivers and certified payroll.

Kos holds what’s billed ahead of the work.
Medium-voltage gear billed ahead of the field and a missing sub-tier waiver come back in Montera’s own review columns, each with the clause behind it.
Every equipment bill drafted in the ERP.
Kos matches the turbine supplier’s milestone bill to the PO and the approved drawings, codes it to the campus and flags freight that isn’t on the PO.

Milestones paid when they’re met.
A milestone billed before the factory test is held with the PO term behind it, so long-lead payments never get ahead of the equipment.
The funding draw ties out.
Pay apps reviewed, equipment bills matched and every finding cited: the draw package is ready before the deadline, and the subs get paid sooner.
