Dispute an invoice

Dear Sir or Madam, I have received invoice [Invoice number] dated [Invoice date] from [Name of the supplier], for the amount of EUR [Amount charged in euro]. I dispute this invoice and will not be paying it while the matter remains unresolved. My reasons are as follows: [Why the invoice is wrong] I ask you either to withdraw the invoice or to send me a corrected one within fourteen days, together with the underlying documents on which the charge is based. If part of the amount is not in dispute, please tell me which part, and I will settle that part on receipt of a corrected invoice. Because the invoice is disputed, I am not in default in respect of it. I therefore do not accept any reminder fee, interest or collection charge relating to this amount, and I ask you not to pass the matter to a collection agency or report it to a credit reference agency while the dispute is open. Please treat this letter as formal notice of dispute and confirm in writing that you have registered it as such. If no substantive reply reaches me within fourteen days, I will refer the matter to the competent disputes body. Yours faithfully, [Your name or company name]
