What to look for in a utility bill audit company
Not all utility auditors deliver the same results. The difference between a firm that recovers real money and one that finds nothing often comes down to three things: business model, industry experience, and how they get paid. Here’s how to evaluate your options before you sign anything.
The fundamentals worth understanding
What separates good firms from the rest
A strong utility auditing firm works on contingency — meaning they only get paid when they find recoverable money for you. This alignment of incentives matters. Firms that charge upfront retainers have less reason to dig deep. Look for depth of experience in your specific industry; a firm that audits grocery chains doesn’t necessarily understand the rate structures and billing rules that apply to manufacturers.
Longevity also matters. Utility tariff structures, state tax codes, and billing systems change constantly. A firm that has been doing this work for decades has seen the errors utilities make repeatedly — and knows exactly where to look.

Questions to ask a utility bill auditor
Do you work on contingency or do I pay regardless of results?
This is the most important question. A contingency-only model means the auditor only earns a fee when they recover money for you. SM Engineering operates 100% on contingency. If we don’t find errors, overcharges, or savings — you pay nothing. No retainer, no hourly billing, no risk to your budget.
What industries do you specialize in, and how long have you been doing this?
Utility billing rules, rate structures, and billing codes vary significantly between industries and states. A firm with broad generalist experience may miss industry-specific savings opportunities. SM Engineering has been auditing utility bills for manufacturers and property managers since 1982 — over 40 years of focused expertise in the rate structures and billing systems these clients encounter every day.
How much of my team's time will this require?
A common concern — especially for lean finance and operations teams. At SM Engineering, our onboarding process is designed to minimize your burden. We begin with a free bill review and handle the heavy lifting ourselves. Most clients spend only a few hours pulling initial documentation, and we manage the rest: analysis, communication with utilities, and refund recovery.
What types of errors or savings do you typically find?
Look for firms that can speak in specifics. Common findings include rate misclassifications (billed on the wrong rate schedule), meter reading errors, demand charge miscalculations, and billing errors that compound quietly over months or years. SM Engineering reviews electric, gas, and water/sewer bills across all of these categories — and pursues refunds retroactively when errors are found.
Do you handle the utility directly, or do I have to manage that relationship?
Coordinating with utilities — especially large investor-owned utilities — takes time and persistence. SM Engineering manages that process on your behalf. We file the paperwork, follow up, and negotiate refunds and corrections directly with the utility. You stay focused on running your operation.
What happens after the initial audit? Is this a one-time service?
The best auditing relationships don’t end after the first review. Utilities make errors repeatedly — especially on complex accounts. SM Engineering offers ongoing monitoring so that future billing errors don’t go undetected. Clients who stay with us over time consistently see additional recoveries that an initial audit alone would have missed.
