AI voice bot ROI: does it pay off and where does it lose clients

Your balance shows only the total charged for calls, and you can’t calculate AI voice bot ROI from it. A bot can call your database for a month and spend money on minutes while almost nobody gets to a booking, for example because the bot’s greeting doesn’t work. “AI conversion analysis” shows what one bot’s calls cost and how much each client who reached the goal cost.

This way you can fairly compare the robot with a human operator and see whether a script change helped. The report itself is free and charges nothing. Watch the two-minute video, and the step-by-step setup is below.

Why businesses need it

• The owner sees whether the robot pays off: how much a client from the bot costs and what the ROI is. ROI shows how many dollars of payments each dollar of costs brought in.
• The head of sales finds the step where clients drop off and checks whether the bot got better after training.
• The marketer calculates the full cost per lead, including the price of the database or the lead from the card’s “Costs” field.
• A clinic compares the cost of one appointment confirmation by the robot with an hour of an administrator’s work. A B2B company compares the cost of a meeting from the bot and from a manager on cold calls; how to launch such a campaign is described in “AI outbound calling bot”.

How AI voice bot conversion analysis works

The report is built on one bot’s calls for the selected period. On the “Overview” tab:

• the “Costs for the period”, “Calls”, “Talk minutes” and “AI share” tiles;
• the “Costs for the period” block by item: telephony, speech recognition, text generation, speech synthesis, lead card update;
• the “Costs by day” chart.

A minute of the bot’s conversation costs $0.12 on average, and the “Costs for the period” block shows what it is made up of for your bot.

You set the goal yourself: it is a conversion scenario, that is, which funnel steps count as success. Conversion is the share of leads that reached the goal. The “Conversions” block shows how many of the bot’s leads “Reached goal”, the “Cost per goal” and ROI.

How to calculate AI voice bot ROI: step by step

1. 1
   Open the analysis

   In the “AI voice bot” section, click “…” next to the bot and select “AI conversion analysis”. The report opens in a new tab.
2. 2
   Choose the period

   In “Period”, for example “Last 30 days”, or set your own “Dates”.
3. 3
   Create a conversion

   Click “New conversion” and fill in “Name”, for example “Booked a consultation”.
4. 4
   Tick the steps

   In “Successful funnel steps”, tick the booking step and all the steps after it.
5. 5
   Turn on payments

   In “Payments”, click “Count payments” to see ROI.
6. 6
   Include the lead price

   If needed, tick a “Costs” type field from the lead card in “Lead costs”.
7. 7
   Save

   Click “Save”. The page switches to “Overview”, and the figures appear in the “Conversions” block.

Where the bot loses customers

Build a “ladder” of scenarios in funnel order: “1. Interest”, “2. Qualified”, “3. Booked”, “4. Payment”. A lead card sits at one step, so in each scenario tick its step and all the following ones. Then the scenario counts everyone who got at least that far. How the bot sets lead steps is described in “Writing call results to CRM”.

Compare “Reached goal” for neighboring steps of the ladder. Where the number drops the most, that’s where the conversation loses people. Open “Call details” and copy the “Call ID”. Find it in the bot card: “Training AI” → “Find a call”. A bad reply is fixed there with the “Fix” button; see “AI voice bot training” for details. Calls are available for the last 7 days.

Which bot script works better

• Before and after: write down “Reached goal” and “Cost per goal” for the week before a change and compare them with the same week after.
• Don’t judge by the first calls: after a prompt change, the reply cache is reset. The first 10–20 calls cost more, and minimum costs return after about 50–100 dialogs.
• Two bots: copy the bot, change the script in the copy and compare the analyses for the same period.
• The “Call details” window hints at the cause. Short calls of a few dozen seconds usually mean clients hang up at the greeting. Long calls without the goal mean the bot drifts off plan. The “Busy” label means the call didn’t get through, not a bad conversation.
