CallSphere plans start at $50/mo (Lite — a basic question-and-answer AI voice agent and chatbot), then $149/mo (Starter), $499/mo (Growth), and $1,499/mo (Scale). Annual billing saves 20%. AI token and telephony usage are billed separately at cost, with no markup — about ~$0.15/min inbound and ~$0.17/min outbound.
What is the cheapest CallSphere plan, and is there a basic question-and-answer AI agent?
Yes. The Lite plan is $50/mo and is our most affordable tier. It's a basic question-and-answer AI voice agent and chatbot that answers your customers' common questions 24/7 from your business info and knowledge base, with email call summaries — up to 500 calls/mo plus a chatbot. Lite does not include booking, order flows, or back-office workflow automation; those start on the Starter plan ($149/mo). AI token and telephony usage are billed separately at cost.
Is there a free trial?
Eligible first-time subscribers receive a 7-day trial through paid-plan checkout. A payment method is required; checkout shows the trial end date and billing terms.
Can I change plans at any time?
Yes. Upgrade or downgrade between Lite ($50/mo), Starter ($149/mo), Growth ($499/mo), and Scale ($1,499/mo) at any time. Changes take effect at the next billing cycle. Prorated credits apply when upgrading mid-cycle.
Do you offer annual billing?
Yes. Annual billing is available at a 20% discount. Lite: $40/mo billed annually. Starter: $119/mo billed annually. Growth: $399/mo billed annually. Scale: $1,199/mo billed annually. Contact sales for multi-year agreements.
How do you handle payments?
Payments are processed by PCI-DSS compliant providers (e.g., Stripe). We do not store card details—works the same for voice calls and chat.
How long does it take to set up?
Simple deployments can be ready in as little as 24 hours. Integration access, workflow scope, and testing determine the schedule for your business.
What does onboarding include?
Onboarding includes a kickoff call, system prompt configuration, tool setup, knowledge base upload, testing, and go-live support. Starter onboarding is self-serve with documentation. Growth and Scale include a dedicated onboarding specialist.
Can I use CallSphere with my existing phone number?
Yes. CallSphere works with your existing phone number through call forwarding or SIP trunking. You can also port your number directly or use a new number provisioned through Twilio. Your callers experience no change — they dial the same number they always have.
