Official component pricing

The practical difference
Where does the rest of the customer journey live?
AXL: calls inside your business workspace
AXL brings voice agents together with CRM, booking, messaging and automation. A call can be one step in a longer process: a lead arrives, an agent asks qualifying questions, and a scenario sends the result to the next action.
This matters when you want the team to manage the customer relationship in AXL as well as the conversation. The agent, booking pages and follow-up tools can share the same account. You still need to configure the instructions, permissions and actions for your particular job.
Retell: voice operations connected to your tools
Retell offers voice-agent building, testing and call operations, with integrations for the systems a business already uses. Its native Workflows can retrieve context before a call and write results to connected services afterward.
For a team keeping its current CRM or helpdesk, this can be a useful fit. Check the exact integration and actions you need: a native connection, a community connector and a custom API function require different setup work.

Price calculations and monthly charges
Usage figures above exclude monthly subscriptions and number rental. AXL Starter starts at $49/month; its included credits can offset AI usage. Retell pay-as-you-go has no platform subscription; a regular US number is $2/month. AXL number rental depends on the selected number.
AXL: $0.0195 connection + $0.0090 recording + approximately $0.1340 AI = $0.1625. Based on a supplied billing example and a reported inbound duration of 1:20. Dividing by 80/60 gives approximately $0.122/min. AI credits use their displayed dollar equivalent; credits and carrier billing can use different precision.
Retell for 80 seconds: GPT-4.1 ($0.045) + standard voice ($0.015) + infrastructure ($0.055) + managed Twilio calling ($0.015) = $0.13/min, approximately $0.173/call. With GPT-5.4 ($0.080) and ElevenLabs ($0.040), the total is $0.19/min, approximately $0.253/call. GPT-5.5 ($0.160) with ElevenLabs totals $0.27/min, or $0.360/call.
Retell examples use standard model tiers and a regular US number. Fast tiers, knowledge bases, advanced denoising, quality assurance and other paid options may add charges. This compares billing examples, not equivalent model quality or a measured Retell call.
From brief to first call
Both have an assistant. The setup still needs a clear job.
Describe the outcome in AXL
Start with what the agent should accomplish: answer an enquiry, qualify a lead, book a time or collect feedback. Give the AXL AI Assistant your business instructions, attach the relevant booking pages and configure an existing number's route. Buying the number remains your action.
Then test a real conversation. Check the answers, what happens when no slot is available, and which scenario branch handles the result. A good setup includes the next step, not just a pleasant voice.
Build and test with Retell Conductor
Retell also offers conversational setup through Conductor. It can help build, refine and simulate agents, with changes reviewed before going live. An AI setup assistant is therefore a capability to evaluate on both platforms.
Use the same brief for your trial: the same business information, booking rules and difficult questions. Compare how much configuration remains and whether the resulting agent follows your instructions.
Compare the whole job
Three scenarios worth testing.
These are example workflows to configure, not claims that every step is enabled by default.
01
A receptionist that books
In AXL: attach booking pages, let the voice agent check availability and reserve an open slot, then review the conversation in call history. In Retell: configure booking tools through a supported calendar connection such as Cal.com or Calendly. Test a full calendar and a caller who changes their mind.
02
A lead that needs follow-up
In AXL: configure an outbound AI-call scenario, extract the answers you need and route the result to a task, message or webhook. In Retell: configure the call and its post-call workflow to update the connected business tool. Check that the right person receives enough context to continue.
03
A quality-feedback call
Ask both agents the same feedback questions and include an unhappy customer in the test. In AXL: optional analysis can extract answers and select a follow-up branch. In Retell: evaluate its post-call analysis and result actions. Distinguish collecting customer feedback from a separate paid call-scoring feature.
Our recommendation
Choose around the work your team needs to finish.
Consider AXL when...
You want voice, customer records, booking and follow-up in the same workspace. It is especially relevant to a business building its wider process in AXL: reception, sales qualification, appointment reminders or webinar follow-up.
Try the complete path from enquiry to action. The useful result is a booked meeting, a clear next task or a customer answer your team can use.
Consider Retell when...
You want to add voice agents to an established collection of business tools and are evaluating dedicated voice operations. Review its agent builder, testing options and the specific native integrations that match your workflow.
During a trial, check integration coverage and actual call bills with the model and voice you intend to keep. A low entry rate alone does not describe your production configuration.
Before deciding, run the same conversations.
Use the same call direction, country, duration and job. Compare answer accuracy, interruptions, successful bookings and whether follow-up actions actually run. Include the full call charge, paid analysis and the monthly tools you still need. The AXL example above is an actual bill; the Retell figures are calculated configurations.
