What You'll Receive
Full Description
Stop losing leads to clunky, robotic phone systems. This service delivers a professionally configured AI voice calling agent that speaks naturally, follows intelligent call logic, and connects directly to your existing tools — so your business keeps working even when your team is offline.
Whether you need a welcome call agent, an outbound lead-follow-up bot, an appointment setter, or a fully automated inbound support line, the right setup makes all the difference between a caller hanging up and a caller converting.
**What you receive:**
Every tier includes a working AI voice agent built on your chosen platform — Vapi, Retell AI, Bland AI, Synthflow, or GoHighLevel — with a core AI LLM model integrated and a call flow designed around your specific use case. Choose the tier that matches the complexity of what you need.
The entry-level setup is ideal for simple tasks: welcome calls, greeting flows, or basic single-purpose bots. The mid-tier adds Retrieval-Augmented Generation (RAG) so your agent can reference your own knowledge base, CRM or database integration so calls update your records automatically, and multi-language support for wider reach. The full-scope tier packages all of this into a comprehensive build with greater delivery depth — suited to agencies, SaaS founders, and sales teams running higher call volumes or more intricate automation logic.
**Platforms supported:**
Vapi · Retell AI · Bland AI · Synthflow · GoHighLevel · n8n · Simpletalk AI
**Use cases covered:**
Inbound and outbound calling · Lead qualification · Appointment booking · Follow-up sequences · Lead reactivation · CRM-connected voice workflows · n8n automations linking voice, forms and databases
**How it works:**
Once you place your order, share your project details via the order chat — your platform preference, call goal, and any tools you already use. The agent is then built, tested, and delivered within the agreed timeframe. If anything needs adjusting, revisions are included on qualifying tiers.
**Who this is for:**
Agencies managing client pipelines · SaaS founders automating onboarding · Sales teams replacing manual follow-ups · Healthcare, real estate, eCommerce and service businesses that need reliable, professional call automation at scale.
Every flow is tested before delivery. If your existing voice agent has issues — dropped calls, wrong responses, missed handovers — troubleshooting and repair work also falls within scope. Describe your situation in the order requirements and the build will be tailored accordingly.

Frequently Asked Questions
Builds are available on Vapi, Retell AI, Bland AI, Synthflow, GoHighLevel, n8n, and Simpletalk AI. Let us know your preferred platform in the order requirements — or if you are unsure, describe your use case and we will recommend the best fit.
Basic covers a simple, single-purpose voice agent — ideal for welcome or greeting calls. Boost adds Retrieval-Augmented Generation (so the agent can draw on your own knowledge base), CRM or database integration, and multi-language support. Premium packages everything from Boost into a full-scope build with complex multi-step call logic and n8n automation connecting all your tools together.
Share your platform preference, the goal of your call flow (e.g. outbound follow-up, inbound booking, lead qualification), and any tools or CRMs you already use. The more context you provide, the more precisely the agent can be tailored. If anything extra is needed, we will follow up via the order chat.
Yes. The agent can be configured for inbound calls (answering live customer enquiries), outbound calls (follow-ups, lead reactivation, welcome sequences), or both — depending on your chosen tier and use case.
Yes. Common issues such as dropped calls, incorrect responses, delays, and missed handovers can be diagnosed and resolved. Describe your current setup and the problems you are experiencing in the order requirements, and the work will be scoped accordingly.
Basic does not include revisions. Boost includes one revision and Premium includes two. A revision covers adjustments to the call logic, flow or integration based on your feedback after the initial delivery. Scope changes that extend significantly beyond the original brief may require a separate arrangement.
The configured agent is delivered live within your chosen platform or account. You will receive guidance via the order manager on how to access and test it. Any credentials or account access needed to complete the build should be shared securely through the order chat.
AI voice agents built here have been applied across real estate, healthcare, SaaS, eCommerce, and general service businesses. The call logic, tone and flow are customised to your specific use case — so the agent sounds appropriate for your audience rather than generic.
