Business to business letter of complaint billing error

Billing errors happen, but you don't have to pay for them. A letter of complaint can be far more effective than a verbal complaint, because the letter goes into the system.

There are a few basics to complaints about billing:

  • Get your own facts straight
  • Provide a comparative reference for the reader
  • Give a correct amount payable, so it can be checked

This is perhaps the archetypal business letter.

You have to make sure your own figures are accurate, and that you can support your claim properly.

To support your claim:

  • Use the billing party's own figure and quoted business terms. (Attach a copy for their information. It does make a point.)
  • Give a good working set of figures and sub totals.

In this case, we're talking about an actual complaint regarding the bill, not simply disputing the bill.

Your complaint should be professional, but clearly phrased and objective.

You may wish to complain about the failure to provide proper itemization, or whatever, but stick to the main points about the basis of the complaint and the amount payable.

In this example, a retailer has a complaint about receiving an incorrect bill, but it's not the first time this has happened. The complaint is that the wholesaler isn't getting his act together. Despite the nuisance factor, the retailer has decided to make himself clear.
