Most field services providers look alike on a website. They list the same services, the same cities and the same promises. The differences show up later, when an engineer cannot get through the door, a report never arrives or an invoice includes charges nobody expected.
These twelve questions help you find those differences before you sign. They are written for IT managers, procurement teams and service delivery managers who need on-site work in several cities. For each one, you get why it matters and what a good answer looks like. Ask for the answers in writing, and send every provider the same list.
What should you ask about scope and process?
Ask how the provider turns a request into a written scope, who covers each city, and what happens when a visit goes off plan. These three answers show how organized the provider really is.
- Question 1: Who writes the scope, and when do I see it? Why it matters: work without a written scope leads to arguments about what was included. A good answer: you receive a written scope before work starts, listing tasks, locations, devices, access arrangements, parts and what counts as done. You approve it, and changes need your approval too.
- Question 2: How do you cover several cities, and who dispatches? Why it matters: multi-city coverage is where providers differ most. Some staff a few areas and pass the rest to others without telling you. A good answer: the provider says who goes on site in each city, confirms coverage for each request before you commit, and gives you one point of contact across all locations.
- Question 3: What happens when a visit goes off plan? Why it matters: parts go missing, access is refused and tasks grow. A good answer: a stated process. The engineer stops and reports, you approve any change in writing, and the provider explains in advance what is billed when a visit cannot be finished.
What should you ask about people and vetting?
Ask who the engineers are, how they are checked and whether you can keep the same people. The engineer at your rack or wiring closet represents you and works near live equipment, so these answers matter more than any brochure.
- Question 4: How do you vet engineers, and what do you check? Why it matters: skills and trust cannot be assumed. A good answer: specific checks such as identity verification, skills assessment, references and background screening where the law allows. The provider also says which checks apply to which type of work, and when they are repeated.
- Question 5: Who actually shows up, an employee or a contractor? Why it matters: the answer affects confidentiality, insurance and accountability. A good answer: an honest description of the model. Many providers work with independent engineers, and that is fine if each person is bound by written confidentiality terms and the provider stays accountable for the result.
- Question 6: Can I request the same engineer, and who is the backup? Why it matters: an engineer who knows your site works faster and makes fewer mistakes, but people get sick or move on. A good answer: a preferred engineer for repeat sites, plus a named backup who meets the same checks.
What should you ask about access and security?
Ask how engineers get into your sites, what they may touch and what paperwork the provider can show. Field work puts a stranger beside your equipment, so your security team will want clear answers.
- Question 7: How do you handle site access, badges and data? Why it matters: facilities have their own rules, and an engineer may be near systems that hold sensitive data. A good answer: engineers follow your site rules, show identification at the door, work only on the devices named in the scope and do not access data beyond the task. Drives and media are handled as you direct.
- Question 8: What insurance and security documents can you show? Why it matters: procurement and security reviews need paperwork, and NIST guidance on supply chain risk treats suppliers as part of your own risk surface. A good answer: documents on request, such as a certificate of insurance, written security policies and, if the provider holds one, an independent audit report such as a SOC 2 report. A provider should say plainly what it does not hold.
What should you ask about evidence and reporting?
Ask what proof you receive after each visit and how problems are reopened. You cannot audit work you did not watch, so the report is your record.
- Question 9: What proof of work do I receive? Why it matters: reports support audits, warranty claims and billing checks. A good answer: a closeout report for each visit with arrival and departure times, work performed, photos and test results where they apply, plus serial numbers and labels for anything installed or removed. Ask to see a sample first.
- Question 10: How do you handle failed or disputed work? Why it matters: every provider has a bad visit eventually. What counts is the response. A good answer: the issue is reopened on the same ticket, the cause is explained in writing, a named manager owns the fix and the escalation path is clear.
What should you ask about commercial terms and exit?
Ask how the quote is built, what it leaves out and how you can end the relationship. Terms decide the real cost, and an easy exit keeps the provider honest.
- Question 11: How is the quote built, and what is excluded? Why it matters: two quotes with the same headline can differ widely once travel, parts, waiting time and after-hours work are added or left out. A good answer: a quote tied to one written scope that lists what is included, what is billed separately and what triggers a change.
- Question 12: How do I leave? Why it matters: you should know the exit before you enter. A good answer: no long lock-in term, no exclusivity, a short notice process, no penalty for ending and a handover of your documentation, reports and records.
How are field services quotes structured, and which terms should you compare?
Most quotes combine a billing basis, rules about time and a list of extras. Put the same scope in front of every provider, then compare the rules below instead of the headline rate. This article gives no prices because they depend on city, hours, skill level and scope. Ask each provider to state its terms in writing.
A fixed price for a defined scope shifts the risk of overruns to the provider. Time and materials bills for the time and parts used, which suits work that is hard to define. Many providers mix both. For a closer look at the trade-off, see the fixed price or time and materials guide linked below.
| Term | What to compare | Why it matters |
|---|---|---|
| Billing basis | Fixed price, time and materials, or a mix | Decides who carries the risk of overruns |
| Time rules | Billing increments, minimum charges and rounding | Short tasks can cost as much as long ones |
| After hours and urgent work | How each is defined and what changes | Night and weekend work is often priced differently |
| Travel and parts | Whether each is included, passed through or marked up | Hidden extras make quotes hard to compare |
| Waiting and cancellation | Whether waiting time is billed, and cancellation terms | Access delays can be billed to you |
| Reporting | Whether photos and closeout reports are included | Evidence is part of the service, not a bonus |
| Term and exit | Contract length, notice and renewal | Defines how easily you can switch providers |
How does Deploris answer these questions?
Deploris answers with a written scope before work starts, vetted engineers drawn from a network, one engagement manager as your point of contact and a closeout report with photos and test results where they apply. Contracts carry no lock-in.
Use the same list with us as you do with everyone else. If an answer is not specific enough, ask again. You can read how an engagement runs on the how we work page, or send a request and compare our written scope with others.
