## Blind after the hammer falls

Buy at auction without tracking what the unit retails for and you cannot tell a good buy from a bad one.

### Did you overpay?

No read on the retail value behind your hammer price.

### Spreadsheet tracking

Manual, slow and out of date, if it happens at all.

### No margin view

You cannot see the gap between what you paid and what it retails for.

## Why manual tracking cannot keep up

A spreadsheet cannot follow every unit to market or tell you the real margin.

### A spreadsheet

- ✕ Manual entry, one car at a time
- ✕ No live retail prices
- ✕ No margin-gap analysis
- ✕ Out of date as soon as it is built

### Auction Stock Analysis

- ✓ Upload a CSV and we find every unit
- ✓ Live retail adverts and prices
- ✓ Fair Market Value and AI price prediction
- ✓ The trade-to-retail margin gap, per car

## Track units from hammer to retail

Our stock analysis tool uses the data we capture across 10,000+ dealers in 14,000 locations and over 650,000 cars daily. It finds every unit you have sold and brings back the latest data, so you can measure dealer performance, follow the retail price and use gap analysis on trade-to-retail pricing.

For each VRM we include a Fair Market Value, a linear regression price based on make, model, variant, mileage and age, and an AI Price Predictor based on availability, velocity to sell and the car's features.

## Fast, clear, data-driven

### Understand your market

Track the retail price and see the margin gap between the estimated sale price and your hammer price.

### Make data-driven decisions

Understand dealer performance post-auction, including time to prep and retail turnover.

### Fast and simple

Straightforward and quick to use, with pricing at low, mid and upper levels.

### Easy to upload

Upload a CSV of VRMs, mileages and sold dates, and we do the rest.

## What each report returns

Upload your stock and get a detailed report that finds the retail adverts for every vehicle, with first-seen and last-seen data and a full pricing picture.

- First seen: seller, date, advertised price, mileage and advert URL
- Last seen: seller, date, advertised price, mileage and advert URL
