Work order management software: assign, track and close every job with photos and a signature
Work order software logs every customer request, assigns it to a technician, shows its status and closes it with photos and the customer's signature on a phone. It replaces the group chat, the paper tickets and the “who went out to that customer?” question.
Work order management software logs every customer request, assigns it to a technician, shows its status and closes it with photos and the customer's signature on a phone. It's built for field service companies: HVAC, electrical, building maintenance, industrial equipment, elevators, pumps, alarms. Any business where one person takes the call and someone else goes out to fix it.
In this guide I'll walk through the life of a work order inside that kind of system, what the tech in the field needs to see, and what the office gets out of it.
How it usually works today
A customer calls or texts. Whoever answers writes it in a notebook or drops it in the techs' group chat: “Mike, tomorrow swing by Oak Street, the AC isn't cooling.” The tech goes, fixes it (or doesn't) and mentions it in passing. The paper ticket, if there is one, comes back crumpled from the truck a week later.
That leaves questions nobody can answer: was the job finished, or is it waiting on a part? What materials were used? Did the customer sign off? And when a customer says “nobody showed up,” you have nothing to show them.
The life of a work order, start to finish
Every order moves through clear statuses. The system shows where each one is and who has it:
- Requested: customer, address, equipment and the problem. If the customer already exists, their history comes up.
- Assigned: the office picks a tech and a day. The tech sees it on their phone with everything they need.
- On the way: the tech taps it when leaving, and the customer can get a WhatsApp or text heads-up.
- In progress: the tech notes what they found, what they did and the parts used, with photos.
- On hold: if it's waiting on a part or an approval, it's paused with the reason, and it doesn't get lost.
- Closed: the customer signs on the screen, a PDF record is generated and the office can invoice it.
What the tech needs on their phone, and nothing else
The most common mistake with this kind of software is cramming the tech's screen with fields they'll never fill in. They're on a ladder or in a mechanical room with their hands full. They need today's jobs in order, the address one tap away from the map, the contact's phone number, the history of that unit and a big button to take photos.
Everything else (pricing, terms, internal notes) stays in the office. If your techs also run periodic checks against a list of items, I covered that in inspection checklist app, and life in the field more broadly in field service technician app.
Photos and a signature: proof the job got done
A before photo and an after photo settle more arguments than any explanation. They're saved on the order with the date and time, and anyone in the office can see them without chasing the tech.
The signature closes the loop. The customer signs with a finger on the tech's phone, and the system puts together a record with the work done, parts, photos and signature. You can send it by WhatsApp or email on the spot. If that record needs your logo and terms, it works just like an automatic PDF quote: it's built from data that's already there.
Who moves each status, and who gets notified
| Status | Who changes it | Notification |
|---|---|---|
| Requested | Office, or the customer from the website | Confirmation to the customer |
| Assigned | Office | To the tech, with the job details |
| On the way | Tech | To the customer, if you turn it on |
| On hold | Tech or office | To the office, with the reason |
| Closed | Tech, with the signature | Record to the customer; to the office for invoicing |
Status names and notifications are set up to match how your company works.
When the owner dispatches everything
At small service companies, the owner answers the phone, hands out jobs and still runs calls. The software doesn't take that role away, but it lightens it: one screen shows which tech is free, which orders are stuck and which have been open for days. The owner can hand dispatching to someone in the office without losing track of anything.
It's the same bottleneck manufacturers hit when the owner writes every quote. The Estructuras 3D blog has a piece on when the owner quotes everything that applies almost word for word to the person who dispatches every job.
One-tap notifications: what I built for Mecohue
In a different industry, Mecohue, a pet shop with a vet clinic and grooming salon near Buenos Aires, has an internal system with appointments, a cash register and one-tap WhatsApp reminders. It's the same logic as “your tech is on the way”: the message comes out of the system ready to go, and someone just confirms it.
See the Mecohue projectFrom repairs to preventive maintenance
Once orders are logged, you get a benefit you weren't looking for: a history for every unit. You see which equipment keeps failing, which customers call most and which parts you always need. That lets you offer maintenance contracts with scheduled visits, which means steadier income. I went into that in preventive maintenance software.
I work remotely from Buenos Aires, Argentina (UTC−3), with video calls and progress you can open from a link. I quote each project based on how many techs you have and what you need. Questions first? Get in touch.
Frequently asked questions
Do my techs need to install an app?
Not necessarily. They can open their orders in their phone's browser with their own login, and save it as a shortcut on the home screen. If they work where there's no signal, like basements or mechanical rooms, it's set up so they can keep logging and it syncs when the connection comes back.
Does a signature on a phone count?
It works as a record that the customer accepted the work, along with the date, time and photos. If you need it to carry specific legal weight for a contract, check with your attorney about what needs to be recorded.
Can I invoice from the system?
The system gets the information ready: what was done, which parts were used and how many hours it took. You keep issuing invoices the way you do now; if you want the two connected, we look at it based on what your accountant uses.
