Tax accuracy case study
A Texas energy retailer ran eight months of billing through CereTax. Its legacy tax engine got 1 in 25 invoices wrong, and two out of three of those mistakes overcharged its customers.
Customer underbilled
Special-district taxes left off the bill entirely. The tax still applies, so you owe it.
Customer overbilled
Local tax charged at the wrong rate, a sign that addresses fell in the wrong jurisdiction.
Both directions
Gross receipts and regulatory fees calculated too high on some bills and too low on others.
About this analysis: eight months of billing (November 2025 to June 2026) from a Texas retail energy provider, about 500,000 invoices, recalculated in CereTax and compared invoice by invoice with the provider's legacy tax engine. Small differences (under 5¢ or 0.15%) were not counted as errors, and invoices with data issues were set aside. Figures are rounded; client identity withheld.
Customer proof
“We've replaced Avalara as our tax solution for retail and wholesale taxing of telecom. Our experience has been stellar in terms of their taxing engine but over-the-top stellar in terms of support, training, onboarding, etc.”
Scott Bell, Senior Product Manager, Carrier Services, Alianza
“Our transition from Avalara to CereTax was great. We were working under a very tight timeline, and it was met on time. The entire project Team was helpful and responsive. I felt like they really cared about our Company and wanted the transition to be seamless. After we went Live, any issues were handled quickly and efficiently. I couldn't be more satisfied with CereTax.”
