Before and after at Dyno-Rod
Before.
Engineers at Dyno-Rod, a UK drain and plumbing company, were so frustrated with their old field app that they sent status updates by text or phone call, and only 37% of them used the app.
After.
Dyno-Rod moved its engineers to the Dynamics 365 Field Service mobile app, and 93% of them used the new one.
A field service mobile app is what technicians carry on a phone or tablet to see their jobs and record the work at the customer's site. Microsoft's version is the Dynamics 365 Field Service mobile app, which comes with the licence at no extra charge. A field service mobile app pays off only when technicians open the app on each job, and that choice gets made in the van, well away from the boardroom where the software was picked.
Dyno-Rod has unblocked pipes across the United Kingdom since 1963 and runs a network of more than 1,100 certified engineers. The old field app was so slow and awkward that staff in the vans phoned or texted their job updates in, which left the office typing every update into the system by hand.
In the trades, the place to head off that kind of workaround is the toolbox talk, which is the short meeting held before the work starts. When it runs ahead of a new mobile field service software rollout, technicians can raise what bothers them about the app, such as location tracking or extra typing, while the settings can still change.
A field service mobile app in Canada also brings rules an employer has to meet before location sharing goes on, starting with Ontario’s written monitoring policy. The talk covers those, and the technicians sign off at the end, the same way they would after a safety briefing.

What does a field service mobile app do for Canadian technicians?
The app puts a technician's whole day on the phone, including each booking, the directions to the site, the tasks to complete and the place to record what was done. Office staff see the same jobs in a browser after each sync, so field notes never get retyped at the desk.
Microsoft's app runs on iOS and Android phones and tablets as well as Windows 10 and later devices. A technician works through each job in a field service mobile app with a handful of tools.
- The agenda lists the day's bookings, and the map view plans travel between them.
- Service tasks and inspections turn each job into a checklist with structured results.
- The camera scans barcodes to find equipment records or fill in fields.
- Time entries record the hours spent for reporting and billing.
- A follow-up work order can be created from the app when a job needs another visit.
Once an admin sets up the offline profile, the app downloads each technician's jobs to the phone and keeps working with no connection. Changes made in a crawl space or a dead zone up north are stored on the device and uploaded automatically once signal comes back.
Push notifications tell technicians when a new booking has been assigned to them, so a change to the day reaches the phone without a call from the office. Dyno-Rod's IT team used these alerts as a standard Field Service feature that needed no custom build. Telephone bookings and matching engineers to jobs came straight out of the box as well.
The screens can be fitted to each trade, since Microsoft built the app on Power Platform. Admins can personalize the app’s forms and views so a refrigeration team sees its own boxes and an electrical crew gets a different set.
What should you look for in a field service mobile app in Canada?
Test each field service mobile app against the concerns a crew will raise at the toolbox talk. A demo that shows a calm day in the office says little about a technician's day in a basement.
- Work with no signal. Jobs stay on the phone in basements and remote sites, and changes upload later.
- Location rules the employer sets. Tracking hours and update frequency are settings, written into a policy the crew can read.
- Input without typing. Scanning and voice take the place of thumbs on a keyboard.
- History on the job. Equipment records and past work orders open from the booking.
- Paperwork on the phone. The customer signs on screen and gets a PDF report.
- Screens the business can change. Forms and views are fitted to each trade by your own admins.
Have a technician run one of yesterday's jobs through the demo app before the contract gets signed. Ten minutes of thumbs on the screen in the parking lot tells you more about mobile field service software than an hour of slides.
Is the Field Service mobile app included in the licence?
There’s no separate charge for Microsoft’s field service mobile app in Canada, where it comes with every Dynamics 365 Field Service licence. Subcontracted technicians get the app on the cheaper Contractor plan.
Copilot comes with the full licence, so voice updates and work order summaries cost nothing extra for in-house staff. That cheaper plan leaves Copilot out, so outside crews fill in their work orders by hand.
What the manager says at the toolbox talk:
Does a field service mobile app track technicians' location?
Dynamics 365 Field Service shares a technician's location only when an administrator turns tracking on and the technician allows access on the phone. Refusing or later revoking that permission keeps the feature switched off. In Microsoft’s field service mobile app, the employer has settings that decide when location is shared and at what interval.
- Tracking times. The admin sets the hours, by day, when the app sends location, and nothing is sent or stored outside that window.
- Refresh interval. The admin sets the wait between position updates, and Microsoft recommends 60 to 300 seconds.
- On-demand location. With a small customization, a business can skip constant tracking and capture a position only when the technician taps a button in the app.
- What customers see. A feature called Track My Technician shows them where the crew member is during the drive and stops once the booking is set to In Progress.
When the feature is on, dispatchers see the technician on the schedule board map and can scroll back through where they've been. Microsoft stores those records in a table called Geolocation Tracking, which admins can open in Power Apps.
Battery life is the other side of location tracking in a field service mobile app. The phone's operating system, power saver settings, charge level and other running apps can all slow the rate at which the app reports position, so a nearly flat device sends fewer updates.
Dyno-Rod had a "find my engineer" service in the works when Microsoft published the story in March 2024. Customers would get a text with a link showing where the orange van is and how long until it pulls up, the same idea Track My Technician brings to a Canadian homeowner waiting on a furnace repair in January.
What the manager says at the toolbox talk:
Does Ontario require a policy for GPS tracking on work phones?
Ontario employers with 25 or more employees on January 1 must have a written electronic monitoring policy in place before March 1 of that year. Ontario gives GPS tracking of a delivery vehicle as an example, and the rule covers personal devices used for work as well. The policy has to say whether monitoring happens at all, and a business that doesn't follow crews still needs a written statement saying so.
“If the employer does not electronically monitor employees, the policy must specifically state this.”
If monitoring happens, the document describes how and when, what the information may be used for, when the policy was written and the date of any changes, and employees must get a copy within 30 days. The tracking times and refresh interval in the field service mobile app fill in that "how" and "when", so the settings and the paperwork should match. The rule doesn't give employees a right to refuse monitoring, and an employment lawyer should check the wording.
How much typing does a field service mobile app need?
Technicians type very little once the phone does the reading and the listening for them. Dynamics 365 Field Service lets technicians scan equipment barcodes, tick off checklists, take photos of the job and describe the work out loud for Copilot to fill in.
Barcode scanning in a field service mobile app finds the right equipment record or fills in a box without typing a serial number. Inspections turn safety checks and service steps into fields the technician taps through, and the results are saved as structured data the office can report on. Notes can be dictated with the phone's own speech-to-text. Dyno-Rod swapped paper checklists for digital ones when the company's engineers moved to the new app.
Can technicians update a work order by voice?
Speaking does the job as well as typing in Microsoft's field service mobile app, and Copilot suggests the matching updates to the work order for the technician to confirm. Microsoft calls the feature AI-powered work order update, which is still in preview.
Copilot can mark service tasks complete and set how many of each part were used. The same description also sets how long the job took and the status of each service line, and nothing changes on the work order until the technician confirms. For a crew that went into the trade to fix furnaces, talking through the job is the easiest paperwork they'll ever do.
Copilot runs in Microsoft's new mobile experience, which isn't open to technicians who work offline. IT picks each crew's screens while planning the field service management software cloud setup.
What the manager says at the toolbox talk
The same licence gives dispatchers Copilot help with scheduling and work order creation, which are the office-side uses of AI in Dynamics 365 Field Service. A technician's voice update and a dispatcher's new booking then end up on the same work order.

Can technicians see what the last tech did on a job?
Each work order in the field service mobile app lists the customer's equipment and its past repairs, along with the site location and the written instructions for the job. The record updates automatically each time a work order is completed, so every visit picks up from the last one.
The functional location field on a work order tells the technician exactly where to go once at the address, such as a particular rooftop unit or a mechanical room on the third floor. With a connection, technicians can also browse every such spot on a site and the hierarchy of assets there.
Copilot adds a recap that pulls together the notes, parts, services, tasks, asset details and earlier work orders on that equipment, so the technician reads one page in the van before walking in. An admin has to switch the feature on for phones.
Notes the technician adds in the field service mobile app joins that history for whoever goes next. Field service work orders hold the written record and the parts in one place, so the following visit starts with what was done and what was fitted.
Can a technician book a return visit from the app?
A technician who can't finish a job selects the follow-up option in the bottom menu of the field service mobile app, fills in a new work order and saves the record so a dispatcher can schedule the visit. The return trip goes on the books from the moment the need is spotted on site, and the office doesn't have to piece the job together from a voicemail.
Dyno-Rod rolled out a parts tracking system to every location in October 2023. Customers and engineers can see which jobs are waiting on a component and when it's due, so the return visit gets booked for a day the piece is on the van.
What the manager says at the toolbox talk
What happens to paperwork with a field service mobile app in Canada?
The paperwork moves onto the phone and goes out before the van leaves the driveway. With a field service mobile app, the technician builds a service report listing the tasks done and the parts used, and the customer gets a PDF copy.
An admin switches on the reporting control before the first job, and technicians can then build one with no signal. The customer signs on screen, and the finished copy saves to the booking's timeline. Time entries feed billing too, so the hours never get written up again after supper.
What the manager says at the toolbox talk
Dyno-Rod set up 15 automated text messages for appointments and billing. Phone calls chasing the office for news dropped once customers started getting them.
The company also put quotes and invoices into one standard format across 54 franchise businesses. In field services management, the completed work order on the phone is the record each invoice is built from.
How do you get technicians to use a field service mobile app?
Crews switch to a new field service mobile app when the tool beats the workaround they already use, and once they've been trained and listened to before go-live. Dyno-Rod's rollout shows both in practice.
Dyno-Rod's engineer app use jumped 56 points to 93% - Microsoft, Dyno-Rod customer story
Dyno-Rod's employees liked the system they had and pushed back on learning a new field service mobile app. The old on-premises setup had been heavily customized over the years, and staff had grown used to every quirk.
“Understandably, employees initially resisted learning a new tool and changing familiar processes.”
A change management team at Dyno-Rod ran several rounds of training and feedback sessions before launch. The company went live with 40 users at the end of 2020 to shake out problems testing hadn't caught, then rolled out to 2,000 people a few days later.
A wave of feedback followed, and the team dealt with the requests quickly. Engineers who had been texting in their updates moved onto the app, and adoption climbed to 93%, up from 37%, on the back of a clearer interface and faster performance.
What the manager says at the toolbox talk
Hold the toolbox talk before the app goes on a single phone. Once the mobile field service software is live, give the crew one place to send feedback, and put a name on each request so every one has an owner.
Toolbox talk sign-off sheet
- Technicians. Run a day's jobs through the inspections using Dynamics 365 Field Service checklists on a test phone and flag any screen that slows you down.
- Dispatchers. Watch a test job move across the field service dispatch software board as a technician changes its status.
- IT leads. Set up the security roles Dynamics 365 uses so each phone opens only its own crew's records, and match the tracking hours to the written policy.
- Owner. Sign the business case built on the ROI of Microsoft Dynamics 365 Field Service before go-live.
Each line on the sheet gets a name and a date before the first phone goes out. The technicians' signatures go at the top, because the success of a field service mobile app is decided on their phones. File the signed sheet with the go-live plan, and pull it out again after the first week of paid jobs on the app to check that every line still holds. If you're in Ontario, hand out the written monitoring policy at the same meeting, since every employee needs a copy and new hires must get theirs within 30 days of starting.

How does Gestisoft train crews on Dynamics 365?
Gestisoft builds Dynamics 365 CRM training around each role's daily work and practical, job-based scenarios, so people learn only the screens their role uses. On a rollout of a field service mobile app, a role-based plan splits the team this way.
- Technicians. Sessions on the app they'll carry, built around the jobs they do.
- Dispatchers. Sessions on the bookings and the board their updates feed.
- Admins. Training on fields, forms, views and security roles, so your own team can fix a screen that slows a technician down.
- New hires. Structured onboarding that gets people working in the system sooner.
Workarounds and spreadsheet habits are the target, and the training replaces them with guided workflows. Written how-to material reinforces each session afterwards, so a technician who missed a detail can look it up in the van.
Because Gestisoft also implements Dynamics 365 Field Service, the training runs on the same field service mobile app your technicians carry. Sessions can come during the rollout or later, when habits need resetting after go-live.
For a single blocker, such as a form your technicians keep skipping, Gestisoft offers short pay-per-session workshops focused on that one problem. The crew gets the fix without a full course.

The term means the app a technician uses on a phone or tablet to see bookings and record the work at the customer's site. Microsoft's version comes with Dynamics 365 Field Service.

Armed with a psychology degree and an irrational obsession with okapis, I've spent the last decade helping bold brands tell better stories. I believe the best writing bends grammar rules on purpose and makes people feel something. When I'm not deep in words or nerding out on buyer behaviour, I'm probably convincing my kids that impromptu kitchen dance parties are totally normal.
