Need help charging the Agent price.
Hey guys. I’m about to onboard my first AI Calling Agent client and I want to price it correctly without making any fake ROI promises. Here’s the situation: This business owner estimates missed calls are costing him ~$113k/year in lost bookings. I’m building an AI agent that answers calls and handles book/reschedule/cancel/check availability using n8n, with voice on ElevenLabs. I’m thinking of charging something like $500/month (so $6k/year), it's a guess honestly. Even if we recover only a portion of the missed revenue (say 50%–75%), the ROI is still massive on paper. But I don’t want to pitch “you’ll get $113k back” and then reality hits: partial retention, no-shows, seasonality, plus monthly tool costs. Neither the retention percentage nor the monthly cost are confident. So I need your help Guys: 1. How do you track ROI properly for calling agents? What numbers do you use as proof: booked appointments, show-up rate, conversion rate, revenue per booking? (PS: I've done market research and know the lost revenue and closing percentage but I'm not sure if the agent will take all the calls of some of them due to any issues, please suggest) 2. How do you structure pricing? Flat monthly retainer, base + usage (minutes/calls), performance-based (per booked appointment), or hybrid? 3. How do you present running costs transparently? ElevenLabs usage, telephony minutes/numbers, n8n hosting, integrations, maintenance. Do you pass-through at cost, bundle it, or add markup? 4. What’s the cleanest way to express “% saved” without sounding like a gimmick? If you’ve sold or delivered AI agents, I’d love to see your exact approach (even a simple template). Your expert suggestions are valued. Thankyou.
