Utility Audit

Our team will review your historical utility spend, all available rate plans offered by your providers and will work directly with them to ensure you are receiving the most advantageous rate with our utility audit. In addition, our utility audit will work to identify tax exemptions that are not being utilized and make sure the exemptions are put in place.


Our expertise in state regulations and billing practices of tariffed providers will help to reduce your operating expenses and recover lost credits and refunds.

Determine. Optimize. Recoup.

Rate Review

Our team reviews electric power, water, natural gas and sewer accounts in our utility audit to ensure you’re receiving the most advantageous rate structure available. We confirm rates for which clients are eligible and calculate whether any existing rate structure offers potential long term savings. We also examine past bills to confirm that the utilities are correctly structuring and calculating amounts due each month.

Tax Exemption

We review the Department of Revenue regulations while completing a utility audit for each state in which our clients do business to determine if they are eligible for tax exemptions that are not currently being deducted. The utility audit compares and analyzes usage by location through careful scrutiny of actual invoice records to confirm accuracy.
