Voice agents and AI receptionists, built for USD 25k to 60k over 4 to 8 weeks, carry heavier usage profiles. Every call involves real time transcription, generation and speech output, and a missed or mishandled call has a visible business cost in a way a slow chat reply often does not.
Voice projects also tend to need more telephony integration and more careful escalation design, which is reflected in the build range.
On the monthly side, both types draw from the same support model, starting at USD 2,500 per month for 10 hours, but voice agents generally consume a larger share of those hours in call review and transcript analysis.
The right comparison is not which is cheaper in isolation but which workflow justifies its running cost. A receptionist that captures every missed call can carry a higher monthly figure than a chatbot answering password reset questions.
