Short answer
Automate the workflow with repeated volume, clear pain, and a safe human-review checkpoint.
The best first AI workflow for a service SMB is usually not a broad chatbot or company-wide automation. It is a narrow operating handoff: lead qualification, estimate follow-up, appointment changes, support triage, invoice handoff, field-to-office update, review request, or weekly reporting.
The reason is simple: a narrow workflow can be measured, reviewed, and improved without turning customer communication or revenue decisions over to an unsupervised system.
