Most service days are won or lost before lunch, and the dispatch board is where it happens. One dispatcher with a clear board can absorb a call-out, an emergency and a job that ran two hours long without breaking a single promise. Without one, the same morning turns into phone calls to three techs and a missed window by noon.
Dispatch board in plain English
Picture a screen with one row per technician and the hours of the day running left to right. Each job is a block on a row: where it sits shows when, how long it is shows the expected duration, and its color shows status. Jobs nobody has taken yet sit in a queue underneath, waiting to be dragged onto a row.
That is the whole idea. The board answers four questions at a glance: who is doing what, where everyone is in their day, what hasn't been assigned and where there's room for one more job.
What should a dispatch board show?
What a good dispatch board shows
- A lane per technician with their working hours and time off
- Each job's arrival window and expected duration
- Live status from the tech's phone: dispatched, en route, working, on hold, done
- Unassigned jobs, sortable by priority, age and value
- Each tech's skills and certifications
- Booked hours against available hours for the day
- Alerts for late jobs, windows at risk and early finishes
Job status: the language of the board
| Status | What it means | Who sets it |
|---|---|---|
| Unassigned | Booked, no tech yet | Office |
| Scheduled | Tech and time set | Office |
| Dispatched | Sent to the tech's phone | Office |
| En route | Tech is driving there | Tech |
| Working | Tech is on site | Tech (or a GPS arrival) |
| On hold | Paused: parts, approval, access | Tech or office |
| Completed | Work done, ready to invoice | Tech |
When the field updates status, the board is the truth. When only the office does, it's a guess.
How dispatchers use the board through the day
- 1
Before the trucks leave
Clear unassigned work for today, cover call-outs, check each tech's first job and confirm parts for the big ones.
- 2
Mid-morning
Watch for jobs running long. Move afternoon jobs early, while there's still time to tell the customer.
- 3
When an emergency comes in
Find who is closest, qualified and free soonest, and decide which planned job moves to make room.
- 4
Afternoon
Fill early finishes with waiting jobs or customers who asked for an earlier visit. Protect the last arrival window.
- 5
End of day
Check every job has a status, carry unfinished work to tomorrow and look at tomorrow's board before leaving.
What rules should the board enforce?
Some assignments are bad ideas, and some are not allowed. The board should know the difference.
- Legal requirements. Under federal rules, anyone who could reasonably be expected to open a refrigerant circuit while servicing covered equipment must pass an EPA-approved certification exam, with separate types for small appliances, higher-pressure and low-pressure equipment.1 Sending an uncertified tech to a refrigerant repair isn't a scheduling choice. State licensing for electrical, plumbing and gas work works the same way.
- Skills. A tech who has never worked on a ductless system shouldn't be first on a ductless no-heat call, even if they're closest.
- Promised windows. A move that breaks an arrival window should be a deliberate choice with a call to the customer, not a side effect.
- Hours. Overlaps, time off and overtime limits.
Dispatch board vs route optimization
| Dispatch board | Route optimization | |
|---|---|---|
| What it is | The live workspace for the day | A calculation that orders and assigns stops |
| Who drives it | A dispatcher making decisions | Software proposing an order |
| Handles | Skills, priorities, customer promises, judgment calls | Drive time and distance, within the rules it's given |
| When it's used | All day | Planning the day and re-planning after changes |
Routing problems are hard: the classic formulation, Dantzig and Ramser's 1959 truck dispatching problem, asked how to assign stops to trucks to minimize total distance, and the field it started is still active.2 That's why most shops use route optimization as a suggestion the dispatcher accepts or rejects, not an autopilot. Drive time is also paid time: federal rules count travel between job sites during the workday as hours worked,3 so every wasted mile costs wages.
How to tell if dispatch is working
| Measure | What it shows |
|---|---|
| On-time arrival rate by window | Whether promises are being kept, especially late in the day |
| Drive minutes per job | How well jobs are grouped |
| Unassigned jobs at 9 am | Whether the morning starts clean |
| Same-day emergencies placed | How well the board absorbs surprises |
| Jobs moved more than once | Whether the plan is stable |
How the dispatch board works in TradesWork
The TradesWork dispatch board puts each technician on a lane with booked hours against bookable hours, arrival windows, a now line and status colors that update from the field app. Drop a job on someone missing a required skill and it warns you; if the matching certification has expired, the assignment is refused. Alerts flag running-late jobs, windows at risk, early finishes and unassigned work today.
The AI dispatcher can draft a full day or re-plan the rest of today after a call-out, but nothing moves until a dispatcher approves it. For how to weigh drive time against revenue and promises, read dispatching for revenue, not just drive time.
