The owner of a two-location physiotherapy clinic asked us a fair question, which was what an AI receptionist would cost, and what will it save?' The answer had three parts, which were a one-off build, a monthly running cost, and the revenue from calls that currently go to voicemail. This guide explains each so you can do the same math for your business.
Key takeaways
- AI agent cost splits into a one-off build (design, knowledge, integrations, testing) and a monthly running cost (minutes, messages, hosting, tuning).
- Voice agents cost more per conversation than chat agents because of speech processing and telephony; agentic workflows are priced by process complexity.
- Judge the return against what the missed calls, slow replies, or manual hours are costing today, not against a salary alone.
What StartAutomate.ai charges
Our setup fees start at $500 for a Starter Agent, which is one agent doing one job on a standard setup, and a custom agent costs between $1,500 and $5,000 or more depending on how deep the integrations go and how many awkward conversations it has to survive in testing.
Systems of several agents start at $2,000, enterprise builds are quoted per project, and monthly support is priced in each proposal, with the full breakdown tier by tier on our pricing page.
The one-off build
The build covers discovery, conversation design, gathering and structuring your knowledge, integrations with your calendar, CRM, or help desk, testing against real conversations, and launch. A focused agent, such as an AI receptionist for one location or a website chat agent, starts at the lower end of our packages. Multi-channel agents with deep CRM logic and approval workflows cost more, and enterprise builds are scoped individually.
The monthly running cost
Running costs scale with usage. For an AI voice agent that means call minutes, telephony, and speech processing; for an AI chatbot it means message volume and model usage; for agentic workflows it means executions and hosting. Add monitoring and tuning, which is what keeps the agent improving rather than drifting. For most small businesses the monthly figure sits well below a part-time hire.
AI receptionist cost, specifically
Off-the-shelf AI answering services are priced per month by call volume and are quick to start, but they are generic. A custom AI receptionist costs more upfront and less per call at volume, and it books into your actual system, follows your intake rules, and speaks about your services accurately. The clinic above chose custom because bookings had to land in their practice software.
AI chatbot pricing, specifically
Chat agents are the most affordable place to start because there is no telephony and conversations are cheap to process. Cost rises with the number of systems the agent connects to and the actions it may take. A support agent reading a help center is simpler than one that can also modify Shopify orders and open Zendesk tickets.
Working out the return
Count the missed calls or unanswered chats per week and estimate what a fraction of them would be worth as customers. Count the hours your team spends on the conversations or tasks the agent would take. Put those against the build and the monthly cost. For the physiotherapy clinic, two recovered new patients a week covered the entire running cost; everything beyond that was return.

Common questions
How much does an AI agent cost?
An AI agent has a one-off setup fee and a monthly running cost. With us, setup starts at $500 for a Starter Agent and runs from $1,500 to $5,000 or more for a custom agent, while running costs scale with call minutes or message volume and typically sit well below a part-time hire for a small business.
How much does an AI receptionist cost?
Off-the-shelf AI answering services charge a monthly fee by call volume. A custom AI receptionist has a higher upfront build and a lower per-call cost at volume, and it integrates with your booking and CRM systems. The right choice depends on whether bookings need to land in your own software.
How much does an AI chatbot cost for a business?
Chat agents are the most affordable AI agent to build and run. Cost depends mainly on how many systems the agent connects to and which actions it can take, not on message volume alone.
