Start with one workflow. Keep your team in control.

Talk through your use case
What if a customer needs a person?

You set the handoff rules. Cleva can route a conversation to your team with the context attached, so the customer doesn’t have to start again.

Does Cleva only answer questions?

Cleva can check availability, book an appointment, update a record or arrange a follow-up. The available actions depend on your workflow, permissions and connected systems.

Do we have to replace our CRM or HIS?

CleverStack can work alongside your existing systems. We scope the connection during onboarding using the APIs, webhooks or file exchange your systems support.

Can we start with after-hours calls?

Yes. Start with agent assistance, after-hours calls or overflow. Review the conversations and refine the rules before expanding to more of your workflow.
