Field service software runs the middle of your business: the call comes in, the job gets booked, a tech shows up, the work gets done and the invoice gets paid. Pick well and the office gets quieter. Pick badly and you'll spend a year on workarounds before you switch again.
This guide gives you a way to choose that doesn't depend on which demo was the most polished. If you're still working out what this kind of software is, start with what is field service management software?
Do you need it yet?
Not every business does. A solo handyman with a paper calendar and a good memory can run fine for a while. These are the signs you've outgrown what you have:
If you ticked three or more, it's time to look seriously. If you ticked one, fix that one problem first. It might not need new software.
What matters most also shifts with size:
| Team size | What usually matters most |
|---|---|
| Solo, or owner plus a helper | Scheduling, estimates and invoices from the phone, payments, a simple customer list |
| 2 to 5 trucks | A dispatch board, a tech mobile app, job notes and photos, a price book, reminders |
| 6 to 15 trucks | Capacity planning, permissions by role, reporting by tech and job type, maintenance agreements, basic inventory |
| 15 or more | Multiple crews or departments, deeper reporting, phone system, accounting and payroll connections, approval steps |
These are rough guides. A three-person roofing crew running big multi-day jobs may need more project tools than a ten-person cleaning company.
Step 1: Map three real jobs from call to paid
Don't start with a feature list. Start with how work moves through your business. Pick three jobs that make up most of your revenue and write down every step, who does it and where the information lives today.
- Plumbing: an emergency drain call, a water heater replacement quote, a yearly commercial backflow test.
- HVAC: a no-cool call in July, a spring tune-up for a plan member, a system replacement that needs a sales visit, a permit and an install crew.
- Electrical: a same-day breaker problem, a panel upgrade with permit and inspection, an EV charger install that needs utility coordination.
- Roofing: a leak inspection, an insurance claim with an adjuster meeting, a multi-day tear-off with a material delivery.
- Landscaping: a weekly mowing route, a spring cleanup, a two-week patio build.
- Cleaning: a recurring biweekly clean, a one-time move-out clean, a nightly office contract.
For a water heater replacement, the steps might be: call comes in, office books a quote visit, tech assesses and takes photos, estimate with options goes to the customer, customer approves and pays a deposit, unit is ordered, install is scheduled, permit is pulled where required, install is done with photos, balance is collected, review is requested, a reminder is set for the yearly flush.
Every step is a place software either helps or gets in the way. This map becomes your demo script.
Step 2: Split must-haves from nice-to-haves
From your job maps, list what the software has to do. Then score each vendor against the same list. A simple weighted sheet keeps you honest:
| Requirement | Weight (1 to 3) | Vendor A (1 to 5) | Vendor B (1 to 5) |
|---|---|---|---|
| Drag-and-drop schedule with tech availability | 3 | ||
| Mobile app that works with weak or no signal | 3 | ||
| Estimates with options and customer approval | 3 | ||
| Take payment from the job | 3 | ||
| Photos and notes attached to jobs | 3 | ||
| Recurring jobs and maintenance agreements | 2 | ||
| Price book with your own prices | 2 | ||
| Accounting sync | 2 | ||
| Automatic customer texts (confirmation, on the way) | 2 | ||
| Reporting by tech and job type | 1 |
Multiply each weight by the score and add them up. The weights here are examples; set your own. The point is to decide what matters before the demo, not during it.
Trade-specific needs vendors gloss over
Most demos show a generic job. Ask to see the parts that are specific to your work.
| Trade | Ask the vendor to show you |
|---|---|
| HVAC | Equipment records by location (make, model, serial, install date), maintenance agreements with visit tracking, seasonal capacity, the handoff from tech to sales |
| Plumbing | A flat-rate price book, options on estimates, photo-heavy job notes, recurring commercial tests with reminders |
| Electrical | Multi-visit jobs, permit and inspection tracking, attaching panel photos and load calculations |
| Roofing | Multi-day jobs with crews, material orders, measurement files and insurance documents on the job, progress billing |
| Landscaping | Recurring routes in a set order, seasonal contracts, crew scheduling, application records where your state requires them |
| Cleaning | Recurring schedules with team assignment, access notes (keys, codes, pets), per-visit checklists, card-on-file billing |
| Pest control | Recurring service plans, treatment and product records, follow-up visits |
If the answer to most of your list is "you can use a custom field for that," the software may have been built for a different trade.
Step 3: Ask vendors the hard questions
Bring these to every demo, and get answers in writing where money or data is involved.
Fit
- Show me my three jobs from call to paid, using my steps, not your demo data.
- What size and type of businesses mostly use this?
- What does the tech see on the phone? Let me hold it.
Pricing and contract
- How is it priced: per user, per tech, per office seat, by tier or by feature?
- What's included in the plan you're quoting, and what are the add-ons?
- Are there setup, onboarding, training or data import fees?
- Do I have to use your payment processing? If so, on what terms, and can I use my own?
- What's the contract length, and how do renewal and cancellation work?
- What happens to my price at renewal?
Data
- Can I export customers, jobs, invoices, notes and photos myself, at any time, in a standard format?
- What happens to my data if I cancel?
- Can I limit what techs see, like prices or customer contact details?
Support and onboarding
- Who does the setup: you, me or a partner? How long does it usually take?
- Will you import my existing customers and price book?
- What support is available on evenings and weekends, when we're busiest?
Pricing models and features change often, so treat any number you're quoted as valid only once it's in your agreement. For more on how the money works, see how field service software is priced and what to budget for field service software.
Step 4: Run a real trial
A demo is a performance. A trial shows you the truth. If a vendor offers a trial or a pilot, use it like this:
- Load a small slice of real data: 20 customers, your top 30 price book items and your actual techs.
- Put one experienced tech and one newer tech on the mobile app for a week, alongside your current system.
- Test the worst conditions: a basement with no signal, a rooftop in bright sun, gloves on.
- Have the office book, reschedule and cancel jobs during a busy morning.
- Send an estimate to your own phone and approve it the way a customer would.
- Take a real payment and follow it to your bank and your books.
- Run one report you'd actually use and check the numbers by hand.
Ask the techs, not just the office. If techs won't use it, the job data will be wrong, and wrong data makes every report useless.
Call two references
Ask each vendor for two customers in your trade and close to your size, then call them. Vendors pick happy references, so ask questions that get past the sales pitch:
- What were you using before, and why did you switch?
- What surprised you in the first month?
- What do your techs complain about?
- What did it end up costing compared with what you were quoted?
- Have you tried to get your data out, and how did that go?
- Knowing what you know now, would you choose it again?
Red flags
- The salesperson shows the office screens but avoids the mobile app.
- Nobody can give you a straight total monthly cost for your team size.
- Exporting your data is "possible through support" but not something you can do yourself.
- Long contracts with automatic renewal and a short cancellation window.
- Every missing feature is "on the roadmap." Buy what exists today.
- The references they offer are all in a different trade or much bigger than you.
Step 5: Plan the rollout before you sign
Most software fails in the rollout, not the selection. A simple four-week plan:
- Week 1: Import customers and your price book. Set up users, roles and job types. The owner and office learn the schedule.
- Week 2: The office runs the schedule in the new system. Techs start adding notes and photos in the app.
- Week 3: Estimates, invoices and payments move over. The old system becomes read-only.
- Week 4: Turn on automatic texts, maintenance reminders and reporting. Fix whatever is annoying people.
Pick your slowest season if you can. An HVAC company switching during the first heat wave, or a landscaper switching the first week of spring, is asking for trouble. Our guide to switching software without losing a week has a fuller checklist.
The short version
Map your real jobs, set your must-haves before any demo, make vendors show your workflow on their phone app, get pricing and exit terms in writing, and trial it with your techs in real conditions. The best field service software is the one your team uses every day without being chased.
