Dealer Inventory Guide

Dealer inventory loses value when records are thin, mixed, or hard to explain to buyers.

Dealer Inventory Guide

A dealer inventory record has to do three jobs at once: identify the car correctly, track what you paid, and show what you can prove today. If those three parts drift apart, the listing, value work, and reporting all get messy fast.

TDG works best when every item is stored as a specific brand, casting, variation, and condition record instead of one broad title.

Build one clean record per item

  • Brand and casting name.
  • Variation details such as color, wheels, tampo, base, and package.
  • Condition lane: loose, carded, boxed, or graded.
  • Cost basis, source, and purchase date.
  • Photo proof that matches the exact item in stock.

What dealers should track every day

Track what came in, what sold, what still needs better proof, and which listings are tied to the wrong variation. A dealer record should also show whether the item is reserved, listed, boxed for shipping, or still waiting for photos.

If you are using TDG as the working record, keep your saved items organized in My Diecast Garage and use the portfolio dashboard to watch the total mix.

What causes pricing mistakes

  • Mixing boxed, carded, and loose comps together.
  • Using a chase sale to price a common issue.
  • Skipping package and accessory details.
  • Trusting a broad title instead of the exact variation.

How to handle low-confidence stock

If the proof is thin, keep the record private or in research mode until you have better photos or a cleaner match. That protects your listings and keeps your internal pricing from leaning on weak comps.

Use TDG as the proof layer

Search the value hub, open the closest casting page, and compare your stock against the linked variation details. When the public page is not ready yet, keep the item saved as a candidate until the match is clear.
