- Original contract/agreement

Legal Notice
Please be advised that under applicable consumer protection laws and the Fair Debt Collection Practices Act (FDCPA), I have the right to dispute any charges that I believe to be inaccurate or unauthorized.

I trust that this matter can be resolved amicably and promptly. Please respond in writing within thirty (30) days of receipt of this letter.

How to Dispute an Invoice Effectively
Invoice disputes are common in business — billing errors, unexpected charges, services not delivered as agreed, or invoices for things you never ordered. Handling them well requires a paper trail, clear communication, and acting promptly. The longer you wait to dispute an invoice, the harder your position becomes: it looks like you accepted the charges by not objecting.
The most effective dispute letters do three things: identify the specific invoice and amount being disputed, explain clearly why you believe the charge is incorrect or unauthorized, and state what resolution you're seeking (corrected invoice, credit, or cancellation). Vague complaints that something "seems wrong" give the other party nothing actionable to respond to and drag out resolution unnecessarily.
Partial vs Full Disputes
When only part of an invoice is disputed, pay the undisputed portion promptly and dispute the rest in writing. This shows good faith, prevents late fees from accruing on the portion you agree with, and isolates the actual disagreement. A dispute letter that covers a specific line item is much easier for the other party to process than a blanket rejection of an entire invoice when you actually agree with most of it.
Consumer Protections for Billing Disputes
For credit card charges, the Fair Credit Billing Act (FCBA) gives consumers strong protections. You have 60 days from the statement date to dispute a charge in writing. During the investigation, you're not required to pay the disputed amount, and the creditor cannot report it as delinquent. The creditor must investigate and respond within 30 days, and resolve the dispute within two billing cycles. This process is separate from a general invoice dispute — it applies specifically to credit card charges.
When to Escalate
If a written dispute doesn't resolve the issue, your next options depend on the amount and relationship. For small amounts, small claims court is often the most practical path — it's designed for exactly these disputes, doesn't require an attorney, and moves relatively quickly. For larger disputes or ongoing business relationships, mediation can preserve the relationship while resolving the disagreement. Litigation is typically the last resort, warranted when the amount justifies the cost and other options have failed.
