Comparison
TradeBasis vs Carbly
A US appraisal platform built on live dealer listings and transparent comp sets — every comparable individually excludable and linked to its source where available. Flat $99 USD/month entry. No per-data-source pricing. No setup fees. Built by a 20-year auto operator who wanted a number dealers can inspect and defend.
The short version
Carbly is a well-built US mobile appraisal tool with a deserved reputation for great support and a powerful auction-lane workflow. It aggregates multiple guide books (J.D. Power, KBB, Black Book, Manheim Market Report) and integrates with 300-plus US dealer auctions. For an auction buyer, Carbly is a serious tool. We're not pretending otherwise.
What TradeBasis is built for: US franchised and independent dealers who want live dealer-listing comps they can inspect, not just an aggregated range. Nearby comps with a statewide cascading radius. One USD-denominated price with all data included — no incremental data-source charges or setup fees. Transparent comp sets where every comparable is excludable and linked to its source where available. Built by a 20-year auto operator for the lot, the desk, and the customer in the showroom.

Where TradeBasis is materially different
Live dealer listings as the primary comp set, not only aggregated guide books
Carbly's foundation is excellent at what it does: aggregate multiple guide books (J.D. Power, KBB, Black Book) and present a recommended range. TradeBasis takes a different approach. For a dealer appraising a 2021 RAV4 Hybrid in Austin, the right comp set starts with nearby Texas dealer listings asking real market prices. TradeBasis pulls comprehensive US dealer listings directly. The comp set is the comparable vehicles for sale right now in your market.
Flat USD pricing instead of per-data-source billing
Carbly's pricing model adds incrementally: $55 USD base, then more for Black Book, more for J.D. Power, more for KBB, more for Real Retail. Each book is a separate add-on. For a dealer wanting full data coverage, the monthly bill depends on the sources selected. TradeBasis is one flat number in USD: $99/month for Lite, $249/month for Pro. All data included. No setup fees or incremental data upcharges.
Click-through, excludable comp sets — not aggregated ranges
Carbly's SpeedView and Appraisal Assistant aggregate multiple book values into a range. That's a sensible design choice when working with multiple data partners. TradeBasis takes the opposite approach: show every comparable dealer listing as its own row, linked to its source where available, and let them exclude individual outliers (kick the $30k declared-accident car) and watch the appraisal recalculate. Both paradigms work; the TradeBasis paradigm is closer to how dealers actually defend a number to a customer at the desk.
A condition slider that can't be tortured into giving the answer you want
One condition slider, capped between 85% and 98% of market. The cap is intentional. A used-car appraisal that can be massaged to whatever the buyer wants it to be is a liability, not a tool. Carbly's range-based aggregation is a fundamentally different approach to the same problem. TradeBasis chose the constraint deliberately because a number you can stand behind in front of a customer is more useful than a number you can land on by adjusting enough knobs.
Who TradeBasis is for
- US dealers whose primary sourcing is customer trades, walk-ins, and front-line acquisitions — not only wholesale auction
- Operators who want published, predictable USD pricing with no setup fees
- Dealers who want one flat price with all data included, not per-data-source charges that scale month over month
- Lot operators who want a desk tool with inventory management, KPI dashboard, and live re-pricing alongside the appraisal
- Anyone who wants the appraiser and the manager looking at the same comp set, with each comparable linked to its source where available and outliers visibly excludable
Who shouldn't switch
- Dealers whose primary sourcing is wholesale auction — Carbly's Manheim, ADESA, and EDGE Pipeline integrations are core to that workflow
- Operators who rely on a native camera VIN scanner at auction or on the lot — Carbly's scanner is purpose-built for that workflow
- Dealers who already pay for and value the multi-book aggregation paradigm (NADA/J.D. Power + KBB + Black Book + Real Retail) and want one tool that combines them
- Operators who prefer aggregated guide-book ranges over individual live dealer-listing comps
For dealers in the middle — operators who do some auction work but also want transparent live comps for trades — TradeBasis can run alongside Carbly as a second data set. Month-to-month terms and no setup fee make that practical.
Frequently asked questions
How does Carbly compare with TradeBasis for US dealers?
Both products serve US dealers but emphasize different workflows. Carbly brings together Manheim Market Report, J.D. Power Values, Kelley Blue Book, Real Retail, EDGE Pipeline, and extensive auction integrations in a mobile-first tool. TradeBasis uses live US dealer listings as its primary comp set, with nearby-to-statewide cascading radius searches and every comparable linked to its source.
How much does Carbly cost compared to TradeBasis?
Carbly's entry pricing starts at $55 USD/month. Carbly uses a per-data-source pricing model: you pay incrementally to add Black Book, J.D. Power, KBB, Real Retail, and other data partners. TradeBasis is flat-priced in US dollars: $99 USD/month for Lite, $249 USD/month for Pro, with all data included and no setup fees. Compare the full set of data sources your store needs when evaluating total monthly cost.
Is TradeBasis a mobile app like Carbly?
TradeBasis is a responsive web application. It runs on mobile browsers, tablet browsers, and desktop browsers without an app store install. Carbly is a native mobile app (iOS and Android) with a desktop sync. If your primary workflow is auction-lane VIN scanning with a phone camera, Carbly's native scanner is purpose-built for that. If your workflow is on the lot or at the desk, the responsive web approach removes the install step and runs on any device.
Does TradeBasis have a VIN scanner?
TradeBasis decodes VINs from manual entry through a three-layer pipeline: local vPIC PostgreSQL, NHTSA live API, and MarketCheck fallback. There is no camera-based VIN scanner in the current product. Carbly's strength is its native camera VIN scanner that reads both barcodes and printed text. For dealers whose primary workflow is auction-lane VIN capture, that camera feature is a real Carbly advantage.
What's the difference between Carbly's Live Local Market and TradeBasis's comp set?
Carbly's Live Local Market shows similar nearby vehicles for sale with average prices and days on lot, aggregated for display. Carbly's appraisal numbers come from aggregating multiple guide book values (NADA/J.D. Power, KBB, Black Book) into a Wholesale and Retail SpeedView range. TradeBasis pulls comprehensive US dealer listings directly as the comp set, displays each comparable vehicle as its own row — linked to the source listing where a source URL is available — and lets the dealer exclude individual listings (kick the $30k declared-accident outlier) and recalculate. Different paradigms: aggregated book values versus live dealer listings as the primary input.
Does Carbly have auction integration that TradeBasis doesn't?
Yes. Carbly integrates with Manheim, ADESA, SmartAuction, EBlock, EDGE Pipeline, and over 300 dealer auctions and digital marketplaces, with auction run list data, advanced search, and watchlists. TradeBasis does not currently integrate with auction platforms. For dealers whose primary sourcing channel is wholesale auction, this is a genuine Carbly advantage. For dealers whose primary sourcing is customer trades and walk-in appraisals, the auction integration is not the deciding factor.
Can I use both TradeBasis and Carbly?
Yes. Many dealers run multiple appraisal tools as a second data set check. TradeBasis is month-to-month with no contract or setup fee, so adding it alongside an existing Carbly subscription is a practical path. The natural split: Carbly for auction-lane workflow and guide-book aggregation, TradeBasis for the desk and lot workflow with transparent US dealer-listing comps. If one tool's number consistently disagrees with the other, that disagreement itself is information.
What makes TradeBasis a strong Carbly alternative?
TradeBasis gives US dealers transparent live dealer-listing comp sets, published USD pricing, no setup fees, and month-to-month terms. Every comparable is shown as its own row, linked to its source where a source URL is available, and can be excluded individually. Carbly remains strong for native mobile VIN scanning and auction integrations; TradeBasis is designed for dealers prioritizing transparent comps and a full desk workflow.
