that sounds ok
I am withholding payment on your invoice until you demonstrate evidence that the agreed-upon service has been rendered. Pretty good and I am not even an attorney, but I am smarter than a fifth-grader.
Instead of saying "what work has been done", you could say "what services have been rendered"....
Now a days , My Lawyers will be talking to your Lawyer.
I have received your invoice, but I am withholding payment until you have shown me what services have been rendered.
that seems ok
An itemised account is requested before payment can be made.
Dear Mr. XXXXX,
Received your invoice March XXX, 2008. However, I will need an itemized bill for my records before I will be able to remit payment.
I would appreciate your prompt attention to this matter, so that we may both finalize this transaction.
Yours most sincerely,
XXXXX
I am writing in reference to the bill I have received, account number (put account number or bill reference number here). I will not be remitting payment at this time as the services have not been performed in an acceptable manner. Please feel free to contact me to resolve this problem.
I have recieved your bill, however, I will not be paying until I am shown what work has been done.
i take all my blame
That sounds to the point to me! I don't see how fancy words can improve that!
I Have Received Your Bill However, I Refuse To Pay Since You Have Not Shown What/That Work Was/Has Been Done.
I have received your statement and will submit payment once I have received an itemized list of what work has been completed.
Dear_________,
I have in fact recieved the bill you have sent me for (list service here), on (list date here), but due to the fact that the service has not been completed to my satisfaction as (promised or guaranteed), i am therefore disputing this bill, and refuse to submit said fee under these circumstances. (If you will kindly get back to me to discuss the options you will give me for completing such said unfinished work, then we can discuss further payments agreements at that time.) Please contact me as soon as possible at (add phone number) to resolve said matters, so this can be quickly resolved in the best interest of both parties. Thank you.
Sincerely,
