How we calculate
- List prices verified in September 2026: Bland, Retell and Vapi. Subject to change without notice.
- Per 100 contacts: 252 dials over three attempts, 31.6 answered, 158.8 to voicemail and 61.6 unanswered.
- Voicemail call on other platforms: 5 billed seconds of detection.
- Go4Clients: the most convenient plan is applied among $250 at $0.14/min, $500 at $0.12/min, $1,000 at $0.11/min, $5,000 at $0.095/min and $10,000 at $0.085/min. Answered calls pay a minimum of 20 seconds and then per second; those that hit voicemail pay only the detection, at $0.0075. The plan's minimum spend does not roll over.
- Bland: the cheapest plan that supports the daily call volume (Start, Build or Scale). If the Scale limit is exceeded, that price is shown and it is flagged as requiring Enterprise.
- Retell: $0.094 to $0.119 per minute depending on voice and model, plus $0.005 per dial in campaigns. Vapi: $0.095 to $0.125 per minute depending on providers; it does not include its voicemail detection cost.
- All connected via SIP; carrier cost is not included in any of them.
- Team time: reference estimates you can adjust in "Adjust hours per task". The initial development of retries, alternate numbers and reports is counted only once, in the first year.
- "Must be coded" or "must be configured" means the platform offers the pieces through the API, but not the ready-to-use feature.

Frequently asked questions
Can I try it before committing?
Yes. With any plan you get a proof of concept to evaluate the agent in your operation, which includes agent development and 400 minutes.
Does the price include everything?
Yes. The price per minute includes the language model (LLM), the voices and the transcription. You only need to add telephone termination, or connect your own carrier via SIP at no cost. Voicemail detection is billed separately, at $0.0075 per detected call.
What happens if I use up my whole plan?
You keep using the platform without interruption. Additional minutes are billed at the same per-minute price as your plan.
What happens to the minutes I don't use?
They don't roll over. The plan's minimum spend is billed in full each month.
How do I cancel?
By canceling your subscription from the platform or writing to our support team.
Who builds the agents?
You do: Go4Clients lets you build them from scratch, with the wizard or from templates. And if you prefer, you can always ask our experts to build it for you.
How long does it take for an agent to be ready?
It depends on complexity. If you start from one of our wizards or templates, a couple of hours is enough. If it's something completely new, it can take several days.
How much does an hour of development with your experts cost?
$35 per hour.
Do I have access to the agent's prompt?
Yes. You can build the prompt from scratch, start from a template or create it with the wizard. Once it's ready, you can modify it whenever you want and test it live.
Can I define input and output variables in the prompt?
Yes. The wizard lets you add all the variables you need, both the data the agent receives and the data it captures during the call.
Can I upload documents or a knowledge base?
Yes. You can upload documents such as policies or FAQs from your end client, and the agent uses them to answer.
Can I duplicate and reuse agents?
Yes. You can duplicate an agent, modify it and reuse it for another campaign or another client.
How many agents can I create?
As many as you need. They can all run at the same time and share your plan's usage.
What languages does the agent speak?
Spanish, with the accent of each country, and English. It also covers over 40 languages.
Can the customer interrupt the agent?
Yes. When the customer talks over it, the agent stops and listens, like in a normal conversation.
What happens if the agent doesn't know how to answer something?
You decide what it does: it can say it doesn't have that information or transfer the call to someone on your team.
Can the agent look up information in real time during the call?
Yes. During the call, the agent can query your system through API or webhooks, for example to check the debtor's balance, and use that response in the conversation.
Can I launch calls from my CRM?
Yes, if your CRM has an API or webhooks. The cost of the integration is evaluated case by case.
Do you have an API to launch campaigns?
Yes. You can create and launch campaigns through the API, and receive the results of each call through webhooks.
How do I use the widgets?
Each agent has a widget section with code ready to copy and paste into your web page.
Try your own campaign with retries and alternate numbers.
