How the pricing works
The billing model is one of the clearest differences.
- Retell combines voice infrastructure, model, voice, and selected feature charges. [1]
- Vapi charges for its platform, with model-provider costs added separately. [2]
- Bland includes model and speech services in its call rate. [3]
- Chatbase plans include monthly message credits. [4]
- Supported.tech publishes plan rates for connected call minutes and chat replies.
Compare phone costs per connected minute. For chat, use the expected monthly volume: a reply and a message credit are different billing units.
