Sample Letter for Not Paying Invoice: Addressing an Invoice Discrepancy
Dear Ms. Rivera,
We hope you are enjoying the new website we rolled out for your boutique on April 20, 2024. Enclosed previously is Invoice #9202 for the design services, totaling $5,000.00, due on May 1, 2024.
Our records show that only $3,450.00 has been received to date. We understand that invoicing errors can happen, so we wish to clarify the following: the final deliverable bundle supposed to include three additional pages—mobile SEO pages—was excluded from the initial project scope. This adjustment was explicitly agreed upon, and a revised invoice was issued on May 3, 2024, with a new total of $1,200.00.
To streamline the process, please review Attachment A (Revised Invoice) and confirm that you agree with the new amount. Once we receive your confirmation, we will issue a payment request for the outstanding balance of $1,200.00 within the next five days.
If you suspect a mistake or have concerns about the billing details, our account manager, David Ellis, is available tomorrow at 10 am or Wednesday at 2 pm for a quick call. Kindly let us know your preferred slot.
We appreciate your immediate attention and hope to resolve this swiftly.
Warm regards,
