Choosing an AI phone assistant: criteria, costs, questions

An AI phone assistant answers calls, captures the request and hands it to your team. According to vendor figures, most offers cost roughly €30 to €500 per month. What matters most is not the price per minute but a clean handover to your staff: who called, what it is about, how urgent it is and when to call back.

Key takeaways

The core points for choosing an AI phone assistant.

  • Billing is per minute (vendor figures mostly €0.08–0.69), per call, or a monthly package with included minutes.
  • For typical small and mid-sized businesses, vendor guides quote roughly €30–500 per month depending on call volume and features.
  • Setup fees range from €0 to about €500 depending on the vendor. Compare costs over twelve months, not just the minute price.
  • The most important check is the handover: name, request, urgency and callback wish must reach the right person in full.
  • Test with real call scenarios before going live, including after-hours calls and your industry's terminology.

7 questions before you buy

These questions separate a usable system from a demo.

How does the handover to my team work?

Do name, request, urgency and callback wish arrive in full, by email, ticket or call transfer?

How is the phone number connected?

Usually your main number forwards to the AI number. Check whether a dedicated number costs extra.

What happens when nobody is available?

The assistant should say so, capture the contact details it needs and schedule a callback.

Does it understand your terminology?

Test customer numbers, names, accents and industry terms with real sample calls.

Where do the answers come from?

Store opening hours, prices and responsibilities clearly. Without clear input a system can give wrong answers.

What does it cost over twelve months?

Add up base fee, included minutes, extra minutes, phone number, setup and integrations.

Where are calls processed?

Clarify storage location, retention period and who can access recordings.
