7 Best AI Voice Agents for Freight Brokers in 2027

If you are choosing an AI voice agent for a freight brokerage, decide the job before you decide the vendor. The seven options below fall into three groups: broker-side agents that answer carrier calls on your posted loads, carrier-side agents that call brokers from load boards, and broader back-office platforms where voice is one channel among email, documents and EDI. Retell AI sits apart as a general voice platform that you configure and wire yourself.

The short answer: for inbound carrier calls on posted loads, start with Parade's CoDriver Voice. For an operation that wants agents across the whole load lifecycle, shortlist HappyRobot or Vooma. For an engineering team that wants to own every call flow, Retell AI is the only one of the seven with per-minute prices on its public pricing page.

An AI voice agent for freight brokers is software that places or answers phone calls with carriers or shippers, applies the brokerage's rules on rates and eligibility, and writes the outcome back to a system such as a TMS.

TL;DR: Parade's CoDriver Voice has the most specific published workflow for inbound carrier calls, Retell AI publishes per-minute rates, and the other five vendors either quote pricing after a sales conversation or show no price at all, so expect to request quotes before you can compare costs.

Key Takeaways

• Pick by call type first. Inbound carrier calls, outbound load coverage and back-office workflows are different products, and mixing them up is the most common way to overbuy.

• Only Retell AI publishes prices in the pages reviewed. The other six are quote-based or show no figure, as checked October 29, 2026.

• Most performance numbers are vendor-reported. Treat Parade's quote-lift and call-volume claims as hypotheses for your own pilot, not results.

• Confirm the TMS, load board and compliance tool integrations in writing before you take a sales call.

• The control that matters most is human approval. Ask who signs off on rates, carrier eligibility and exceptions, and where that approval is logged.

• A build on a general platform means you own retries, duplicate handling, escalation design and ongoing maintenance.

How we evaluated these tools

This is an informed buyer's guide built from public vendor pages and documentation, trade press, and one research firm's company profile. We read each vendor's own pages where they were available, plus FreightWaves coverage, a joint DAT and Parade release, and a Sacra profile. The weights below are our judgment about what matters to a small brokerage in its first months with a voice agent. They are not a vendor score.

Two limits apply to every row. Most vendors here publish no prices, so cost comparison depends on quotes. And several of the strongest claims come from the vendors themselves, so we label them as claims in each profile.

The seven options at a glance

The table shows what each vendor's own materials or the trade press describe. Our reading of where each one fits is in the profiles and the checklist. US Tech Automations is deliberately not a row here. We describe how a configured workflow would fit your stack in prose, in the build section below, where the prerequisites and review points can be checked.

Per-vendor profiles

Parade CoDriver

Parade's CoDriver Voice answers calls placed to the phone number posted on a load. It asks for the carrier's MC number, checks eligibility in your compliance tool, looks up the load, collects a quote and transfers the call to a rep when a condition is met. Parade's Voice 2.0 page describes a rebuild with three modes: qualify-only, full automation, and strict compliance mode that works with third-party compliance tools. Parade reports 27% more quotes from the same call volume according to Parade (2026), based on an A/B test across "thousands of real calls" with no baseline numbers published.

DAT's joint release with Parade says the DAT One integration lets brokers turn on CoDriver's phone and email features inside their existing DAT workflow. The same release reports, as vendor claims with no time period, a 40% reduction in phone call volumes and a 90% improvement in carrier response times, according to DAT (2025).

Best fit: a brokerage that posts loads on DAT One and gets steady inbound calls about those postings. Limitations: a call about a load without the CoDriver number on its posting falls outside the flow, and the Voice product must be enabled through a customer success manager. Carrier eligibility depends on your compliance tool, so the agent is only as good as that connection. Human review: transfers go to a rep when a quote meets your conditions, when the carrier asks for a person, or when the carrier or load cannot be identified. The Parade help article says calls and quotes are logged in a CoDriver tab, and it describes no separate review step beyond that. Setting Book Now and Max Rate is optional. Without them, quotes are still collected, but no reference price is given and no threshold transfers happen.

Who should choose it: a broker whose main problem is the phone queue on posted freight. Skip it if most of your carrier calls concern loads that are not posted on DAT One.

HappyRobot

HappyRobot's own llms file describes a platform organized around Agents, Performance, Context and Interfaces, with voice that works across more than 30 languages according to HappyRobot (undated). The same file says workflows can start on inbound calls and lists operations use cases such as appointment scheduling, track and trace and dispatch. Its developer surface includes a REST API, a TypeScript SDK, an MCP server and a Web SDK. Pricing is described as custom enterprise contracts, with a demo request through its contact page.

HappyRobot: $150 million Series C at $1.2 billion according to FreightWaves (2026). That coverage, dated August 4, 2026, also says the company has more than 150 enterprise customers, though it gives no date for that count, and names DHL, Uber Freight, Kuehne+Nagel and LKW WALTER among them.

Sacra, a research firm, describes HappyRobot's pricing as likely tied to usage volume or active workers rather than per-seat, while disclosing no price points, according to Sacra (2025). Treat that as Sacra's inference.

Best fit: operations with enough volume and budget for an enterprise procurement cycle, and a need for voice across several channels. Limitations: the llms file names sales outreach and track and trace, but it does not name check calls or inbound carrier calls as a product. Implementation is vendor-led. The same file says Prisma, its team that builds and manages the platform for each customer, does that work, so expect a managed deployment rather than a self-serve setup.

Vooma

Vooma's documentation describes six agent workflows: Quote, Build, Schedule, Cover, Track and Collect. It also describes a platform layer with Insights, Standard Operating Procedures, and Command Tower, which monitors the AI workforce and handles escalations. The docs list a Public API for custom TMS builds and communication channels for email, telephony and internal chat, per the Vooma documentation. The Cover workflow, as described on Vooma's site, posts loads to DAT and Truckstop, handles inbound calls and emails, vets carriers, negotiates rates and books freight.

Vooma's site lists integrations with Turvo, McLeod, DAT Rateview and Ratecast, Truckstop, Tai, Revenova and RingCentral, among others. Pricing is not shown; the only call to action is a demo request.

Best fit: a brokerage that wants one vendor to handle work from quoting through collections. Limitations: that breadth means a longer rollout than a single phone agent. The docs we reviewed do not describe a dedicated voice feature set, so ask for voice call flows in writing. Escalation is handled through Command Tower, which is where a person would see exceptions.

FleetWorks

FreightWaves' September 3, 2025 coverage describes FleetWorks as an AI carrier agent that finds carriers and monitors loads for brokers, and as a virtual dispatcher that finds loads and flags issues early for carriers. Channels named are voice, email, SMS, WhatsApp, Google Chat and Telegram, and the product verifies drivers by photo and voice. FleetWorks manages over 5,000 trucks according to FreightWaves (2025). The same article reports, as company claims, 30% month-on-month growth and a 1% reduction in procurement costs for brokers.

The article also cites a goal to connect with half of all active U.S. carriers by August 2026. That date has passed, and the sources we reviewed do not say whether it was reached. The official site text came back empty when we read it, and third-party directories describe pricing as custom. We found no verifiable price, so we list it as quote-based.

Best fit: brokers and small fleets that want help on both sides of the call across several messaging channels. Limitations: the most recent independent coverage we found is from September 2025, so ask the vendor which channels are live on your account and which are roadmap items.

Bubba AI

Bubba AI's page describes an outbound voice and messaging agent that starts when it detects matching spot freight on DAT or Truckstop. It dials the broker's listed number and can contact several brokers in parallel. It confirms availability, piece counts, hazmat status, appointment windows, equipment, weight and accessorial terms. It counteroffers within floor and margin limits and escalates to a human dispatcher when an offer falls below the margin floor or when accessorial or hazmat terms are unclear. The page lists DAT, Truckstop, Uber Freight, FreightLink and Parade, plus TMS connections through REST APIs and webhooks, and cites 100+ freight tech integrations according to Bubba AI (undated page).

The page shows a "Start FREE" button and a demo request, but no price or plan terms.

Our reading: the negotiation logic runs on the carrier's floor and margin, which places Bubba AI on the carrier side of the call. A brokerage would mostly be on the receiving end of these calls, not the buyer. Limitations: the page names inbound handling but does not describe it. Red flag: a broker that expects this to be an outbound sales tool for its own team.

Pallet

Pallet's brokerage page describes agents across account management, coverage and tendering, load execution, and settlement and audit. Tenders go out by email, voice or digital booking, and declined or unconfirmed tenders are escalated. The page says agents work "inside of every channel including email, voice, API, and remote desktop." Pallet claims 45 days to live deployment according to Pallet (undated page). The same page also says "Go live into production within 6 weeks," so its own timelines conflict, and it claims a 10% net margin improvement and 3x loads per operator. Those are vendor claims.

Best fit: brokerage operations teams that want back-office automation for invoicing, settlement and document collection, and can accept voice as a secondary channel. Limitations: we found no standalone phone product on the page, check calls are not named, and no prices are shown. Ask for the go-live timeline in writing, because the page gives two.

Retell AI

Retell AI is a general voice-agent platform, not a freight product. Its public webhook documentation lists events such as call_started, call_ended and call_analyzed, plus transfer events, and warns that retries can cause duplicate deliveries, so handlers must be idempotent, according to the Retell webhook documentation.

Best fit: an engineering team that wants its own call flows, freight rules and TMS write-back. Limitations: the material we reviewed shows no packaged freight workflows, so you build carrier eligibility, rate limits and escalation yourself. The pricing page also shows two versions of its monthly fee tables with differing notes, so confirm the current rates before budgeting. Skip it if you want packaged carrier workflows.

Pricing and cost math

Pricing checked October 29, 2026. Only one vendor in this group publishes figures on its own pricing page. Retell pay-as-you-go voice: $0.07 to $0.31 per minute according to Retell AI (2026), with a $0.055 per minute voice infrastructure component, $0.015 per minute for text-to-speech, $0.015 per minute for telephony on listed Twilio and Telnyx routes, and 20 concurrent calls included before a $8.00 per concurrent call monthly charge.

Every vendor marked quote-based showed no figure on the pages we could read. The Retell rows come from its pricing page, and no other figure in this table comes from a source we did not open.

Here is an illustrative scenario, not a customer. A two-desk brokerage handles 600 inbound carrier calls a month, averaging 4 minutes each, which is 2,400 minutes. At the component rates above, plus a GPT 5.4 mini model rate of $0.024 per minute, the voice, speech, telephony and model components total $0.109 per minute, or $261.60 a month. Adding the $0.005 per minute knowledge base add-on brings the total to $273.60. Three simultaneous calls sit inside the 20 included, so no concurrency fee applies. Building the handler is a cost too: Retell's call_ended event has to be deduplicated on event and call_id, because retries can deliver it twice, and that work belongs in your build estimate, not in the per-minute rate.

Two cautions apply. Retell's estimator example shows telephony at $0.00, so the headline per-minute figures can understate a real bill if you forget telephony. And the page's two fee tables disagree on some monthly items, so confirm before you budget.

Build it yourself or configure a workflow

For many small brokerages, the real alternative is not another vendor. It is stitching a phone platform to a TMS with Zapier, Make or n8n, or building the connection in-house. Those tools can support run histories, retries, error branches and audit evidence when they are configured that way. What you still have to design and own is observability, idempotency, escalation paths, access controls and maintenance. Retell's own documentation shows the detail: retries can cause duplicate deliveries, so the handler must deduplicate, and a no-code chain often hides that work until something breaks.

A configurable design from US Tech Automations could start with unresolved inbound carrier calls. The trigger is a call that ends transferred or unresolved in the voice platform, delivered as an event or a log export. The action is a lookup of the load in your TMS through its API or a scheduled export, with the MC number, the compliance status and the call transcript attached. The output is a task for a rep with the load ID, the carrier and the quoted rate already filled in. Prerequisites are read access to the TMS, the voice platform's event or log feed, and access to the compliance tool. Review points: any rate outside the approved band goes to a dispatcher, and eligibility decisions stay with whoever owns the compliance tool. This is a proposed design, not a live deployment, and it implies no measured result.

A second configurable workflow covers loads still uncovered close to pickup. US Tech Automations would trigger it when a load has not reached covered status by a time the brokerage sets, read from a TMS export. The action queues outreach to carriers on the brokerage's approved list, through the phone or email channel it already uses. The output is a daily exceptions report listing attempts, outcomes and the loads that need a manual rate decision. Prerequisites are a TMS export with load status, the approved carrier list, and send permissions on the outreach channel. Rate changes and final booking confirmation stay with a person, and the brokerage sets the outreach limits.

Who this is for

This guide is for owners and operations leads at small brokerages that already run a TMS or load board and handle a steady volume of carrier calls about posted or uncovered loads. Red flags: no TMS or load board export or API access, nobody who can approve rates and carrier exceptions, or a plan that expects an unattended rollout within a week.

Decision checklist and when a simpler tool wins

• Name the call type you want handled first: inbound carrier calls, outbound coverage, or back-office work.

• Ask each vendor for its integration list for your exact TMS and load board, in writing.

• Ask who approves rates, carrier eligibility and exceptions, and where that approval is logged.

• Ask for the go-live timeline in writing. At least one vendor page gives two different figures.

• Ask for a written quote that includes telephony and add-ons, since the per-minute rate may not be the whole bill.

• Ask which performance claims the vendor will support with its own customer evidence, and which are marketing.

When NOT to use US Tech Automations: if your phone volume is low, the voicemail and call-forwarding tools already on your phone system may be enough, and a configured workflow adds upkeep without much return. If your TMS already has a native voice integration covering the same call type, use that first, because a separate build duplicates it. If you want one packaged product with no internal design work, a vendor such as Parade or Pallet is closer to that goal than a configured design.

Terms used in this guide

• Check call: a call to a driver or carrier to confirm a load's status and location.

• MC number: the motor carrier number a carrier gives a broker to identify itself.

• Posted load: a load listed on a load board, which carriers see and call about.

• Spot freight: a one-off load booked close to pickup rather than under a contract lane.

• Accessorials: charges beyond the base line-haul rate, such as detention or lumper fees.

• Idempotency: a handler design that processes a repeated event once, not twice.

Frequently asked questions

Which AI voice agent fits inbound carrier calls best?

Parade's CoDriver Voice has the most specific published workflow for inbound calls on posted loads, but only if your loads carry its phone number and your compliance tool connects to it. Confirm both before you start a trial. It is the closest match in this group to the call type most brokers mean when they search this term.

Does any vendor publish prices?

Retell is the only one of the seven with figures on its pricing page, at $0.07 to $0.31 per minute for pay-as-you-go voice agents. The other six are quote-based or show no price on the pages we reviewed, so ask for a written quote.

How reliable are the performance numbers?

Treat them as vendor claims until a pilot confirms them. The quote-lift, call-volume, load-coverage and go-live figures in this guide all come from vendor pages or joint releases, not from independent audits, so run a pilot on your own call data first.

Can a broker use Bubba AI for its own outbound team?

Probably not as a broker's outbound sales tool, because its described negotiation logic runs on the carrier's floor and margin. A brokerage would more often receive these calls, so confirm the intended use with the vendor before assuming otherwise.

Do I need engineers to set one of these up?

Retell is a platform you configure and wire yourself, and its webhook documentation makes that work visible. The other vendors describe setup through their own teams, such as enabling CoDriver Voice through a customer success manager, but you should still ask how much TMS integration work falls on your side.

Where to go from here

Start with the call type, then check one integration before one sales call. For inbound carrier calls on posted loads, shortlist Parade and ask in writing whether its DAT One or TMS integration covers your setup. For wider coverage across the load lifecycle, shortlist HappyRobot or Vooma and ask for the quote and the go-live timeline in writing. For an engineering team that wants to own the flow, Retell is the only option here with public per-minute rates, and the build plan must cover duplicate handling and escalation. If you want to see how a proposed workflow would be configured for your stack, see how US Tech Automations configures this and bring your TMS export and your approval rules.
