DAT bundles its TMS with its load board. Keelway lets you pick your own.

What DAT's TMS actually is

DAT (Direct Action Transportation, the company behind DAT Freight & Analytics) built its business on the load board. The TMS layer inside DAT One is a strategic extension: keep the broker inside the DAT environment for the full lifecycle of a load, not just posting and sourcing. From a product standpoint it's competent — load records, carrier profiles, basic document handling, accounting hooks. From a depth standpoint it's a second-priority product behind the load board itself, and that shows.

The bundled pricing model is the giveaway. DAT does not publish a standalone TMS price because the TMS is not a standalone product — it is a retention layer on the load-board subscription. That's smart business for DAT and fine for some brokerages. It's a poor fit for any brokerage whose biggest daily pain is carrier-email volume, because DAT has no reason to invest deeply in inbox AI: their core product is upstream of the inbox.

Side-by-side: DAT One vs Keelway TMS

What DAT's TMS is

DAT's TMS is the natural product extension of being the largest load board in North America. Once a broker is paying $300+/month for the DAT subscription, DAT can offer a TMS layer at low incremental cost — and capture the entire lifecycle of a load inside one environment. The architecture is straightforward: posted loads on DAT flow into DAT One's TMS automatically, carrier contacts pulled from DAT searches land in the same database, and documents/records live alongside the load board you already use.

For very small brokerages — say one to three people — that tight coupling can be enough. You get a single login, a single invoice, and DAT support handles both the load board and the TMS. It's a defensible choice if your operation is small enough that you don't feel the limits of the TMS layer.

Where DAT One actually wins

Two honest advantages over Keelway:

• Single-vendor convenience. One subscription, one invoice, one support relationship, one login. Procurement is simpler. There's no second integration to manage. For brokerages that value simplicity over depth, that's real.
• Load board integration depth. DAT's TMS is literally built by the load board company. The handoff from "I posted this load on DAT" to "this load now exists in my TMS" is native, not via API. If you live in the DAT load board all day, that's smoother than any integration anyone else can build.

Neither of these matters much once your daily pain is the carrier email volume DAT generates rather than the load posting itself. That's the inflection point.

Where Keelway wins

Three concrete reasons a pure freight brokerage picks a standalone TMS over DAT's bundled one:

• Inbox AI is the core product, not absent. Every posted DAT load generates 10-40 carrier replies in your inbox. DAT's TMS doesn't touch that stream. Keelway reads every reply, parses the offered rate from the email body, scores the carrier against FMCSA continuously, and ranks the top five inside Gmail. That's where the day actually happens.
• You keep DAT. Keelway is BYO-load-board by design. Your DAT subscription doesn't change. You drop DAT's TMS layer (and any incremental cost it bundles in) and replace it with a real TMS that has its own opinion about carrier email. Best of both products.
• Published flat pricing. $400/month, unlimited users, no contract, printed on the TMS landing page. DAT One's TMS is bundled inside tiered load-board pricing — you can't actually tell what the TMS portion costs, which makes vendor-vs-vendor math impossible.

The bottom line

DAT One's TMS is fine for the smallest brokerages that prize single-vendor simplicity above feature depth. For any brokerage covering 50-300+ loads/month, the bundled TMS becomes the weak link in a stack where the load board itself is excellent. Keelway is the natural other half: $400/mo flat, AI carrier-email triage as the headline feature, integrates with the DAT load board you're already paying for. You don't replace DAT; you replace DAT's TMS.
