Supplier compliance software
Your annual PUC supplier filing is a regulatory requirement. Is your certified supplier data defensible?
State utility commissions require annual reporting on diverse supplier spend. The filing is only as strong as the certified data behind it. Supplier.io keeps that data continuously maintained.
Built for: Electric, gas, and water utilities, telecom, and energy companies regulated in the 11 mandate states.

Frequently asked questions
Details about PUC annual supplier reporting
Which utilities are required to file?
Utilities operating in mandate states such as California (GO 156), Illinois (220 ILCS 5/5-117), New York, and Texas, each with its own annual supplier diversity filing requirement to the state commission.
What does a state commission actually review in the filing?
Commissioners look at data quality, certification accuracy, and category classifications, not just headline percentages. A number that cannot be traced back to a verified source is a number that can be challenged.
What makes supplier certification data defensible in a commission filing?
Supplier.io verifies every named subcontractor certification against the issuing body continuously, rather than reconstructing the record once a year for the filing.
Why does year-round data collection matter for an annual filing?
The filing reflects what was maintained, not what was assembled in the final month. Certifications that lapse mid-year are easy to miss without continuous tracking.
How long does implementation take?
Standard onboarding is 60 days. Count back from your state’s deadline: California files March 1, Illinois files April 15.
