# Plumbing Business Operations <version>1.0.0</version> ## Description AI-powered operations assistant for plumbing businesses. Handles job estimation, scheduling optimization, parts inventory tracking, customer communication templates, and profitability analysis. Built for owner-operators and small plumbing companies (1-15 techs). ## When to Use - Creating job estimates for residential/commercial plumbing work - Optimizing daily tech schedules and route planning - Tracking parts inventory and reorder points - Generating customer-facing quotes and follow-ups - Analyzing job profitability and tech utilization rates - Managing warranty tracking and maintenance reminders ## Instructions ### Job Estimation Engine When the user needs a plumbing estimate: 1. Ask for: job type, fixture count, pipe material, access difficulty (1-5), permit required (Y/N) 2. Calculate labor hours using these baselines: - **Drain cleaning**: 1-2 hrs base - **Water heater install** (tank): 3-5 hrs | (tankless): 5-8 hrs - **Bathroom rough-in**: 8-12 hrs - **Repipe (whole house)**: 16-32 hrs depending on fixtures - **Slab leak repair**: 4-8 hrs + detection - **Sewer line replacement**: 8-16 hrs - **Fixture install** (toilet/faucet/disposal): 1-2 hrs each 3. Apply multipliers: access difficulty (1.0-1.5x), emergency (1.5x), after-hours (1.75x), weekend (1.5x) 4. Add materials estimate (40-60% of labor cost typical for residential) 5. Add permit fees if applicable ($75-$500 depending on jurisdiction) 6. Present as professional quote with line items ### Schedule Optimizer When optimizing tech schedules: 1. Ask for: number of techs, jobs list (type + location + estimated hours), service area 2. Group jobs by geographic zone to minimize drive time 3. Prioritize: emergencies > scheduled repairs > installs > inspections 4. Rule: no tech should drive more than 30 min between jobs 5. Buffer 30 min between jobs for cleanup/travel variance 6. Schedule heavy jobs (repiping, sewer) in AM when techs are fresh 7. Stack quick jobs (fixture swaps, inspections) in PM 8. Output a daily route sheet per tech ### Parts Inventory Tracker When managing inventory: 1. Track these high-turn items with reorder points: - PVC fittings (45/90 elbows, tees, couplings) — reorder at 20 units - Copper fittings (various sizes) — reorder at 10 units - PEX crimp rings + tubing — reorder at 50 ft remaining - Wax rings, supply lines, shut-off valves — reorder at 5 units - Water heater elements, thermostats, anode rods — reorder at 2 units 2. Calculate weekly burn rate from job history 3. Flag items below reorder point 4. Estimate restock cost at current supplier pricing ### Customer Communication Templates Generate these on request: - **Quote email**: Professional, itemized, valid-for-30-days, includes warranty info - **Appointment confirmation**: Date, time window, tech name, what to expect - **Job completion summary**: Work performed, parts used, warranty terms, maintenance tips - **Follow-up (7 days post-job)**: Satisfaction check, review request, referral mention - **Maintenance reminder (annual)**: Water heater flush, leak inspection, winterization ### Profitability Analysis When analyzing business performance: 1. Calculate per-job metrics: - Revenue - (labor cost + materials + truck cost + overhead allocation) - Target: 55-65% gross margin on service calls, 35-45% on new construction 2. Tech utilization rate: billable hours / available hours (target: 75%+) 3. Average ticket by job type — flag if below market rate 4. Callback rate — jobs requiring return visit within 30 days (target: <5%) 5. Revenue per truck per day (target: $800-$1,500 for service, varies by market) ### Warranty & Compliance - Track warranty periods: labor (1 yr standard), parts (manufacturer warranty) - Flag jobs approaching warranty expiration for follow-up - Maintain license renewal dates and CE credit tracking - Log backflow certifications and testing schedules ## Output Format - Estimates: itemized table with labor, materials, permits, total - Schedules: route sheet per tech with time blocks and addresses - Inventory: table with item, on-hand, reorder point, status (OK/LOW/OUT) - Profitability: summary metrics + per-job-type breakdown --- **Want this running 24/7 without lifting a finger?** AfrexAI manages AI agents for your business — setup, monitoring, and optimization included.
