Limitations, Risks & Failure Modes
What may not apply to you, and what could go wrong:
- Self-reported per-client prices, not total revenue
- Inbox access involves sensitive client data and data protection rules
- Active service work, not passive income
Key Takeaways
- A low-priced audit can open a recurring retainer
- Small, steady automations keep clients longer than flashy builds
