The honest answer: $15K–$150K depending on complexity, data readiness, and how many systems it needs to talk to.
$15K–$30K: Simple workflow agent
- Single data source (your CRM, a document set)
- One clear task (triage, summarization, drafting)
- Standard integrations (Slack, email, common SaaS)
- Timeline: 3-4 weeks
$30K–$75K: Multi-step agent with integrations
- Multiple data sources that need reconciliation
- Complex logic with branching decisions
- Custom integrations or legacy systems
- Human-in-the-loop workflows
- Timeline: 6-10 weeks
$75K–$150K: Production-grade agent system
- Enterprise security and compliance requirements
- Multiple agents working together
- Custom UI and monitoring dashboards
- SOC 2, HIPAA, or similar compliance
- Timeline: 12-16 weeks
What drives cost up:
- Messy data that needs cleaning
- Legacy systems without APIs
- Complex approval workflows
- Regulatory requirements
What keeps cost down:
- Clean, accessible data
- Clear workflow definition
- Single integration point to start
- Existing API infrastructure
