Field Service Clinic: Share proven fixes for scheduling, parts, and first-time fixes

Quick call for first-hand experience from field service ops teams: what recurring problems are still bleeding time or margin (crew scheduling, inefficient routes, missing parts on-site, piles of paperwork, slow invoicing, missed SLAs, low first-time-fix rates, etc.), and what concrete changes actually moved the needle? Please include: company size & vertical, the specific problem and metric you tracked, the exact solution or workflow you implemented, tools/integrations used (configs or automation rules if possible), measurable before/after results, and any templates or sample configs you can share. If a change failed, say why and what you tried.

To keep replies actionable, use this short template in your post:
- Context (company size, vertical)
- Problem & baseline metric(s)
- Solution / workflow change
- Tools, integrations, and key config snippets
- Before / after results (numbers preferred)
- What failed or unexpected tradeoffs

We’ll run focused weeks (scheduling week, inventory/parts week, mobile apps week) and collect playbooks and repeatable configs. If you’re open to it, note whether you’d volunteer a short post-mortem or let others DM you for configs/templates. First-hand reports and concrete numbers are most useful — please share what actually changed, not vendor marketing.
