How to make a dealer addendum sticker
It takes about a minute a car:
Enter the VIN
Decode the VIN to fill in the year, make, model and trim from NHTSA's data, or type them yourself. The VIN prints on the addendum once it checks out.
Add the car's price
Enter the price before add-ons if you want the addendum to show the full total. Leave it blank to print the add-ons and their sum only.
List each add-on
Give each item a plain name and its price, such as window tint or wheel locks. Enter 0 for anything included at no charge, and the addendum says No charge.
Add your dealership and a QR code
Your name, phone and logo go across the top. Paste a link, such as the car's page on your website, and a QR code prints at the bottom.
Print it
Print on letter paper or full-sheet label stock, or save it as a PDF from the print dialog.
What is a dealer addendum?
A dealer addendum is a second sticker on a car's window that lists what the dealership added after the car left the factory, with a price for each item and a total. Dealers also call it an addendum sticker, a supplemental sticker or an add-on sticker. On a new car it sits next to the factory window sticker, known as the Monroney label, which lists the automaker's equipment and price.
The two do different jobs. Federal law requires the Monroney label on new cars and says no one may remove or alter it before the car is delivered to the buyer, so a dealer's add-ons go on a separate sheet beside it instead of on the label. No federal rule requires an addendum, and some states have their own rules on how dealer add-ons are priced and shown, so check yours. When a car does carry add-ons, a clear addendum shows the shopper where the price above the sticker comes from.
What to put on an addendum sticker
Shoppers read an addendum to answer one question: what am I paying for on top of the sticker price? Make each line answer it.
- Name each item plainly. "Window tint, front and sides" says more than "Appearance package".
- Price every line. If something is included at no charge, enter 0 and the addendum says so.
- Keep the total consistent. It should match what a salesperson will quote and what your online listing says about add-ons.
- Say what's optional. If a shopper can turn an item down, the note line is a good place to say so.
- Match the car. Print a fresh addendum for each car, with its VIN or stock number, so it can't end up on the wrong window.
Common lines include window tint, wheel locks, mud flaps, all-weather floor mats, nitrogen in the tires, paint and fabric protection, and anti-theft etching. On new cars in short supply, some dealers add a market adjustment; if you do, call it that.
Addendum, window sticker or Buyers Guide?
Each sheet on a car's window has its own job:
- The factory window sticker comes from the automaker on new cars and lists the car's equipment and MSRP. For a used car, our free window sticker lookup finds the original when the automaker posts it online.
- Your own window sticker sums up a used car's features and price. The free window sticker maker prints one from the VIN.
- The addendum lists what your dealership added, with prices and a total, on new or used cars.
- The FTC Buyers Guide is required on used cars a dealer offers for sale, and says whether the car comes with a warranty or as is. Our free Buyers Guide maker fills it in for you.
An addendum never replaces the factory label or the Buyers Guide. It goes beside them.
What should the addendum's QR code open?
Any https link you paste. Point it at a page for that one car, such as its listing on your website, so a shopper walking the lot after hours can see the photos and the price. If you shoot your cars with CarShots, every car has a Car Page with its photos, walkaround video, window sticker and history link, made for this. Scan the preview with your phone before you print, and print a new addendum if the car's link changes.
How to print addendum stickers
The addendum prints on one letter-size page, portrait, in black and white, so any office printer handles it. Print on plain paper and put it inside the window beside the factory sticker, or use full-sheet adhesive label paper if you stick addenda to the glass. To keep a copy or send it to a print shop, choose Save as PDF in the print dialog.
The maker remembers your dealership's name, phone, note and add-on list in this browser, so the next car starts with your usual lines and you only change what's different. The car's details and your logo aren't kept. Only the VIN leaves your browser, when you press Decode VIN, to look it up in NHTSA's data; your add-ons, prices and dealership details stay on your device.
