What is a “billable minute”?
In most plans, billable minutes are the time an agent spends handling calls for your account. That can include greeting, qualification questions, holding/transferring, and documenting a message.
- Short scripts usually reduce minutes (and cost).
- Long qualification and repeated transfers increase minutes.
- After-hours calls can add minutes if you don’t have clear routing rules.
Common pricing structures you’ll see
- Bundled minutes: pay for a block (e.g., 100/200/500 minutes), then overage per minute.
- Pure per-minute: base fee plus a per-minute rate.
- Tiered plans: bundles + features (hours, transfer types, integrations) tied to tiers.
Add-ons that change the “real” cost
Even if the per-minute rate looks good, add-ons can shift the total:
- Additional phone numbers or toll-free numbers
- Dispatch / on-call escalation (complex transfer chains)
- SMS/email notifications for every call
- Call recording and storage
- Integrations (CRM/helpdesk), if not included
How to estimate minutes (without guessing)
- Pull the last 30–60 days of call logs: call count + average handle time.
- Separate business-hours vs after-hours (after-hours often drives wasted minutes).
- Identify “out of scope” calls (wrong service area, spam, misdials) and add a guardrail question.
Then compare to AI routing: if you can shorten or automate qualification, usage drops and follow-up speed improves. See answering service cost vs AI receptionist.
Bottom line
Per-minute pricing can be cost-effective when scripts are short and routing is clear. If calls are long or transfers fail often, you’ll pay more and still lose outcomes. Use the ROI calculator to sanity-check savings from recovered leads + saved admin time.
