Context
Sales 100% dependent on human operators to attend, qualify, send contracts, and collect payment.
Manual signature process (PDF + digital signature in separate flows). Manual payment (PIX generated and sent in separate message). Service limited to business hours, leads lost after hours.
Scale blocked by the human bottleneck. Each agent handles one client at a time. Cost grew linear with volume.
Decision
CPF Azul didn't need more agents. It needed an autonomous sales cycle, service, qualification, contract, payment, operating 24/7, without human dependency.
We decided to build the complete integrated cycle: AI contextualized as a persona ('Sofia'), proprietary CRM, OpenPIX for collection, digital signature for contract. All inside WhatsApp.
Build
Complete WhatsApp automated cycle:
- ·'Sofia' AI agent, contextualized persona with lead classification
- ·Full integration with proprietary CRM (admin dashboard for funnel management)
- ·OpenPIX integrated for automated collection inside the flow
- ·Digital signature platform integrated to send and sign contracts in the conversation
- ·Direct WhatsApp self-contracting, from the first 'hi' to signed contract and confirmed payment, without a human operator
Evolution API 2.3 · Contextualized AI agents · Groq Whisper · OpenPIX · Digital signature · Hostinger VPS.
Outcome
- →Complete automated cycle: service → qualification → contract → payment → confirmation.
- →24/7 operation, after-hours leads now convert.
- →Human operator freed for complex cases and strategic sales.
- →Real scalability of the model: volume grows without growing proportional headcount.
