Dispatch Workflow

# Service Call Flow:
# 1. Customer calls → Helpdesk ticket or CRM lead
# 2. Dispatcher assesses urgency:
#    ├── Emergency (burst pipe, no heat) → Same-day dispatch
#    ├── Urgent (slow drain, AC weak) → Next-day
#    └── Scheduled (maintenance, install) → Book ahead
# 3. Assign technician → Based on skill, location, availability
# 4. Technician receives job on mobile
# 5. Travel → GPS check-in on arrival
# 6. Diagnose → Document issue, take photos
# 7. Quote → On-site estimate or flat-rate price
# 8. Customer approves → Work begins
# 9. Execute → Record labor time, parts used
# 10. Complete → Customer sign-off, invoice generated

Parts and Truck Inventory

Each technician's truck is a mobile warehouse in Odoo. Common parts (fittings, valves, filters) are stocked on each truck. When a technician uses parts on a job, truck inventory is decremented and the cost is allocated to the job.

  • Main warehouse + virtual locations per truck
  • Truck restocking transfers from warehouse
  • Parts consumed on field service tasks auto-deducted from truck stock
  • Minimum stock levels per truck with restocking alerts
  • Special order parts for installation jobs tracked on purchase orders

Job Costing

Every job in Odoo tracks total cost: technician labor (hours x rate), parts consumed, subcontractor costs, and permit fees. Comparing job cost to the invoiced amount shows profit per job, helping identify which services are most profitable.

  • Labor cost: technician hours x hourly cost rate
  • Parts cost: actual cost of materials consumed
  • Travel time tracking (billable vs non-billable)
  • Subcontractor costs for specialized work
  • Job profitability report by service type, technician, and customer

Flat Rate vs Time & Material

Plumbing/HVAC companies use both pricing models. Odoo supports flat-rate pricing (predefined prices for common jobs like water heater install) and T&M billing (actual hours and parts). Configure each service type with the appropriate pricing model.
