Billing Error

A billing error is a charge appearing on a periodic statement that was not authorized by the cardholder or their designee, is not properly identified, was not accepted by the cardholder, or results from the creditor's failure to credit a payment or from an accounting or clerical mistake. Consumer credit laws in most jurisdictions give cardholders a formal right to dispute a billing error within a set window, commonly 60 days from the statement date.

Once a billing error dispute is lodged in writing, the creditor must investigate and respond within a defined period, and cannot report the disputed amount as delinquent to a credit bureau while the investigation is pending, which distinguishes a formal billing error dispute from an informal customer-service complaint that carries no such legal protections.

A billing error is any charge on a statement that simply should not be there, whether because it was fraudulent, mislabelled, or the result of a bank's own mistake, and consumers have a specific legal process, not just a customer-service phone call, for getting it fixed.

• Charges from a transaction the cardholder never made or authorized.
• A payment the cardholder made that was never credited to the account.
• A duplicate charge, or a charge for the wrong amount, due to a merchant or processing error.

To invoke full legal protection, a cardholder generally needs to notify the creditor in writing, rather than only by phone, describing the suspected error clearly enough for it to be identified and investigated, since a written notice is usually what triggers the formal timelines and protections set out in consumer credit law.

A formal billing error dispute under consumer credit law is distinct from, though sometimes overlapping with, a merchant chargeback dispute over goods or services not received as promised, and cardholders unsure which process applies are generally best served by raising the issue in writing to the card issuer, who can direct it to the correct process.

Keeping receipts, confirmation emails and screenshots related to a disputed transaction significantly strengthens a billing error claim, since the creditor's investigation will typically weigh any evidence the cardholder can provide alongside its own transaction records before reaching a final decision.

A subscription that continues charging after a cardholder cancelled the underlying service is a common type of billing error dispute, and documenting the cancellation date and any confirmation received from the merchant significantly strengthens the dispute when raised formally with the card issuer.

While the formal dispute process runs between the cardholder and the issuer, the issuer typically contacts the merchant for its side of the story before making a final decision, meaning a merchant with clear records of a genuine, authorized charge can often successfully defend against an unfounded dispute.

An authorized or additional cardholder generally has the same right to raise a billing error dispute over a specific transaction they did not make or recognize, even though the account itself belongs to the primary cardholder, giving every named user on the card some direct recourse rather than needing to route every dispute through the primary account holder.

A billing error dispute involving a foreign currency transaction can be more complex to resolve, since the exact amount charged may depend on an exchange rate applied at a specific moment, and verifying whether that conversion was calculated correctly sometimes requires the issuer to review records from the relevant card network rather than just its own internal systems.

Cardholders are generally encouraged to review each statement promptly rather than waiting, since the formal window to dispute a billing error, while often generous, is not indefinite, and a genuine error discovered too late can become considerably harder, or even impossible, to formally dispute under the standard consumer protection timeline.
