How this tool works

Pick your bill type, choose whether you're writing to the company or a regulator, fill in the details, and we generate a professional dispute letter with the correct regulatory citations. Everything runs in your browser — nothing is sent to our servers.

When to send a company dispute

Start here. Most billing errors are resolved by contacting the company directly with a clear, specific letter. Reference exact charges, dates, and amounts. Companies have internal dispute processes and are often required by law to respond within 30 days.

When to file a regulator complaint

Escalate when the company doesn't respond within 30 days, denies a valid dispute, or continues collection on disputed charges. Different bill types go to different regulators:

Medical bills: State Insurance Commissioner, State Attorney General, CMS (Medicare)
Utility bills: State Public Utilities Commission (PUC) or Public Service Commission (PSC)
Phone/internet: FCC (federal), State Attorney General
Insurance claims: State Department of Insurance
Other bills: State Attorney General, Consumer Financial Protection Bureau (CFPB), Better Business Bureau

Before you send: checklist
