Are you using the most reliable value data available?
Top Bid is the choice of valuation professionals.
Verified Auction Results
Top Bid’s auction results are highly standardized and verified. Top Bid double checks all auction listings to ensure the model number, serial number, and year of manufacture agree.
Lowest Cost of Ownership
When investing in equipment, you buy the lowest “total cost of ownership,” not just the cheapest purchase price. Similarly, Top Bid offers you the lowest “total cost of ownership” for your equipment value data.
Unsurpassed in U.S. Auction Coverage
Since our client base buys, sells, and appraises equipment mostly in the U.S., broad U.S. coverage provides the most applicable values for your needs.
