Kaltheon
Product
The billing engine for commercial subcontractors.
Kaltheon produces your complete monthly billing package from your own contracts and cost data. Every number drafted, every form filled, every document checked, ready for your review.
Every form filled
Matched to your general contractor's exact requirements.
Every document attached
Pay applications, waivers, COIs, and backup in one package.
Every rejection trigger checked
Issues flagged before the general contractor sends the package back.
Product
One complete package, ready to submit.
A monthly billing package is not one document. It is a stack of pieces that all have to be correct and consistent with each other. Kaltheon produces the whole stack from your contract and cost data, and checks that every piece agrees with the rest.

The pay application
Your billing on the exact form your general contractor requires, the standard industry forms or a general contractor's own custom version, filled and calculated.
The schedule of values, with progress drafted
Every line item on your job, with this month's progress drafted from your cost data and the math tied out against your contract.
Change orders, worked in
Approved change orders are built into the billing, so you bill for the work that was agreed and nothing is left out.
Lien waivers
The waivers required for this payment, generated from your own documents, including waivers for your suppliers and lower-tier subcontractors.
Insurance certificates
Your certificates included and checked for currency, so an expired one does not stop the payment.
The pre-submission check
Before it reaches you, Kaltheon runs the package against the known reasons packages get rejected, the math, the form, the documents, and flags anything worth a second look.
How it works
Set up once. Every month, the package builds itself.
Kaltheon does the heavy work at the start, when you set up a project. After that, each month collapses to two things: enter this month's progress, and review what Kaltheon drafted.

Set up the project
You bring your contract, your schedule of values, and the general contractor's form. Kaltheon reads the form once, you confirm it, and from then on every package for that project is built on it correctly. This setup happens one time per project.

Enter this month's progress
Each month, your team enters how far each line item has come. That is the only recurring input Kaltheon needs. Everything else is drawn from what it already holds.

Kaltheon drafts and checks
Every number is calculated against your contract, change orders are worked in, retainage is figured, and the waivers and certificates are pulled together. Then the package is checked against the reasons packages get rejected, before it ever reaches you.

The system of record
Not a form you fill. Where your billing lives.
Most billing tools are something you open once a month, fill out, and close. Kaltheon holds the whole picture between billings, so each month builds on the last instead of starting over.

Your contract and schedule of values
The agreed line items and prices for each job, held in one place, so every month's billing is measured against the same source of truth.
Your change order log
Every change to the contract price, tracked over the life of the job, so nothing agreed goes unbilled and nothing unapproved slips in.
Your billing history
Every package you have produced, period by period, so this month knows exactly what last month billed and what has already been paid.
Your retainage ledger
The money held back on every payment, tracked as it accrues, so you always know what is owed to you and what is still being held.
Because Kaltheon holds the whole job, not just this month's form, every package is consistent with the one before it, and nothing has to be rebuilt from memory.
Your control
Kaltheon drafts. You decide.
Everything Kaltheon produces is a draft for your review. It calculates, checks, and assembles, then stops and hands the package to you. The decision to submit is always yours.
