How to: dissatisfaction letter to a vendor
Make sure your complaint letter is professional. (Stockbyte/Stockbyte/Getty Images)

In business transactions, there might be times when a problem arises that cannot be easily resolved by phone calls. Problems could arise from the quality of goods received, late deliveries, poor service, late payment penalty, or not completing a task in the required time frame. You need to put your concerns in writing.

Skill level:
Moderately Easy


  1. 1

    Review the purchase order and agreement for the terms that are in question about goods or services you are dissatisfied with. If you have already made phone calls, send a letter outlining your problems and what the vendor said in response.

  2. 2

    Write a letter to the vendor outlining your concerns. Keep copies of all letters you send to the vendor. After each contact, send the vendor a confirming e-mail outlining the issues that were addressed satisfactorily and any outstanding issues. This can be a short note but keep it respectful and professional.

  3. 3

    If you have not received complete satisfaction, you need to codify your complaints in a more formal dissatisfaction letter to a vendor. The important items to include in the letter are: terms of the agreement, delivery or performance dates, problems encountered, and copies of the e-mails you have sent concerning the issues.

  4. 4

    While a lawsuit is always possible to resolve a problem with a vendor, this should be the last resort. Lawsuits are expensive and time consuming. If a lawsuit is absolutely necessary, the vendor complaint letters will be a big asset to your case.

Tips and warnings

  • Keep the tone professional and do not use sarcasm or threats. The goal is to resolve problems not exacerbate them.
