Below are some examples of how TriStem has helped our clients recover utility bill overcharges.

Results are combined from electric, street light, gas and water audits.






























































"As a result of TriStem’s audit the Department received refunds from the utility provider of $193,228.00.  In addition, the correction of the billing errors will now save the Department $72,460.00 per year . . . We were pleased to receive the refund with no up-front cost to us . . . We would not have been able to identify these billing errors without TriStem’s help.  I was very pleased with and recommend the service TriStem provides."

“I would highly recommend TriStem as a potential business partner.  We found them to be a professional organization at all levels along with a highly skilled auditing staff. . . . They were successful in obtaining refunds and credits for the Postal Service of approximately $3.8 million. . . . you will not be disappointed in their service nor the results.”

"Thanks for the excellent communication and follow-up. Bureaucracies have their rules and they usually serve to daunt someone to the point they give up. You haven't and we are so grateful."

"Tri-Stem has been one of the best things that has happened to the City of Brownwood in a long time. They have helped us to recover over-billings in electricity and communication charges and savings going forward that were very significant.  They have been very professional, diligent and hard-working.  We could not be more pleased with our relationship."

"During this engagement the City has found TriStem to be a highly reputable company.  TriStem’s staff possesses a broad knowledge of utility operations, rates, pricing and billing practices. . . . Thus far, the City has been issued two large refund checks with other refunds pending.  We now pay less for electricity today than in the past. Of course, the true beneficiaries of TriStem’s work are the citizens of St. Louis."
