Key differences
Why teams switch from Invoca to Sherlock
AI Voice Agent Investigation vs Enterprise Call Attribution
Sherlock Calls
Sherlock is built for the moment when an AI voice agent call fails in production: it correlates Twilio error codes, ElevenLabs latency spikes, Vapi session IDs, and CRM records in a single cross-provider investigation triggered from Slack.
Invoca
Invoca is designed for enterprise marketing teams attributing inbound human call conversions to digital campaigns. It has no integrations with AI voice providers and no capability to investigate AI-generated call failures across a multi-provider stack.
Zero-Code Slack Setup vs Enterprise Professional Services
Sherlock Calls
Connect Sherlock to Twilio, ElevenLabs, and HubSpot by entering API keys in Slack. Operational in under 2 minutes. No implementation project required.
Invoca

Sherlock Calls starts with 100 free credits — no credit card required. Add Slack, connect your providers, and start investigating calls the same day.
Invoca
Invoca targets enterprise customers with custom pricing, typically starting at $1,000/month or more. There is no self-serve free tier or trial without a sales process.

FAQ
Frequently asked questions
What is the difference between Sherlock Calls and Invoca?
Invoca is an enterprise revenue intelligence platform for attributing inbound human call conversions to digital marketing campaigns. Sherlock Calls is an AI voice operations tool for teams running AI voice agents on providers like Twilio, ElevenLabs, and Vapi. They solve different problems for different teams — marketing attribution vs. AI call failure investigation.
Can Invoca debug AI voice agent failures on Twilio or ElevenLabs?
No. Invoca has no integrations with AI voice providers like ElevenLabs, Vapi, or Retell. It is designed for inbound call attribution from human marketing channels, not for debugging AI-generated call failures across a multi-provider stack.
Is Sherlock Calls a good Invoca alternative for AI voice teams?
Yes — if your use case is AI voice agent operations rather than enterprise marketing attribution. Sherlock connects to AI voice providers directly, operates in Slack, has a free tier, and is operational in minutes. It is purpose-built for the problems AI voice teams face: silent failures, cross-provider correlation, and per-call cost investigation.
How do I migrate from Invoca to Sherlock Calls?
No migration complexity. Sherlock Calls connects to your AI voice provider API keys in Slack — no implementation project required. If you currently use Invoca for inbound marketing call attribution, that use case is unrelated to AI voice operations and you can run both tools independently.
Does Sherlock Calls replace Invoca?
Only if your team runs AI voice agents rather than inbound marketing call centers. Invoca is not designed for AI voice provider integrations, cross-provider call investigation, or Slack-native operations. For AI voice operations, Sherlock Calls is the right tool. For enterprise digital marketing attribution, Invoca remains strong.
