OpenClaw for Plumbers — Job Scheduling, Quote Generation and

Plumbing businesses live and die by scheduling efficiency and quote accuracy. Between dispatching jobs, tracking parts, following up on leads, and managing invoicing, there's a mountain of admin work that pulls you away from billable hours. OpenClaw automates the coordination layer.
