The Situation

Power plants bought before the data halls.

Beacon brings its own power: hundreds of gas engines and turbines feed its campuses, ordered early so the schedule holds. Every order bills in milestones, from deposit to factory acceptance to delivery, each campus is its own entity, and the contractors’ pay apps start arriving as the halls go up.

  • Duplicates refused before they’re entered
  • Every page of the pay app read against the contract

How Kos Works It

Every milestone, matched before it’s paid.

  1. Every campus’s bills land in one inbox.

    Engine suppliers, contractors and haulers email the AP inbox. Kos reads each bill and knows which campus entity it belongs to.

  2. Kos runs the checks an AP accountant would.

    Vendor, PO, haul tickets, duplicates, entity and GL, checked on every bill, then drafted in the ERP for approval.

  3. Or ask in Slack.

    What’s left on the engine PO? Kos answers in the channel with the milestones paid, drafted and still to come.

  4. Pay apps read against the contract.

    As the halls go up, Kos reads every page of the contractor’s pencil draft and holds stored equipment without backup and hours the payroll doesn’t support.

  5. Friday’s run, ready to approve.

    Every bill matched, every pay app reviewed, every amount on its campus entity. Beacon’s team approves the run.
