Utility Bill Audit

Utility bill audit that checks every bill before it’s paid.

We encode your rate schedules, meter logic, and tenant bill-back rules — so every bill gets audited before it’s paid.

  • AI implementation services
  • Every bill checked before payment
  • Your rate schedules, encoded
  • Fixed fee — no percentage of recovery

Built with the leading AI platforms

The broken Friday

Every site bills differently. Nobody re-checks the rates.

From property and facilities finance teams we have sat inside: multi-property operators billing utilities back to commercial tenants, with rate schedules nobody verifies.

  • Tenant bill-back done by hand

    Utility costs get allocated to tenants in a spreadsheet, against lease clauses nobody re-checks — recovery percentages drift from the lease, and the shortfall compounds across the portfolio.

  • Compliance reporting assembled from feeds manually

    Energy Star and utility compliance reports get built from utility feeds nobody has connected — download, re-key, reconcile, repeat, every reporting period.

  • The rate schedule nobody verifies

    The tariff sheet says one number, the bill says another. Verifying the applied schedule means knowing every site’s rate code — and nobody has time to check.

  • Every property, a different format

    Each site’s bills arrive in a different format, portal, and cycle. Before any checking can happen, someone has to work out what the bill even is.

  • The audit that only looks backward

    A utility audit firm sweeps last year’s bills, takes a percentage of recovery, and leaves. This year’s bills keep paying the same errors — nothing changed.

What manual costs

The leak is small per bill. It is not small per year.

We do not quote industry error rates — they are easy to inflate and useless for your decision. The two-week audit puts figures on your portfolio before anything gets built.

How it works

We encode your exceptions.

No new system for your team to learn. The rules your best property accountant carries in their head become the audit.

  1. 01

    Map the rules

    With your finance lead, we write down every rule a bill gets judged by: each site’s rate schedule, meter logic, and the lease clauses driving tenant bill-back.

    Weeks 1–2
  2. 02

    Encode the audit

    Bills get scored against your rules before payment runs. Wrong rate schedules, meter anomalies, and allocation violations hit a review queue; your team approves exceptions, not every bill.

    Weeks 3–8
  3. 03

    Recover and report

    Flagged variances route into dispute and recovery; the same data generates tenant bill-back and Energy Star compliance reporting. The audit keeps pace with every billing cycle.

    Ongoing
Not another tool

Utility bill audit companies find last year’s money. Encoded rules stop this year’s leak.

Utility audit firms work retrospective, percentage-of-recovery: they sweep twelve months of paid bills, take a cut of the clawback, and leave the process as they found it. The same errors get paid again next quarter.

Bill-pay platforms process; they do not verify. We are neither — our AI reads every bill against your rate schedules, meter logic, and bill-back rules, encoded into a continuous audit inside your existing AP flow, no percentage of your money.
