Service report: what it is, what to include and a free template

Read it with AIChatGPTClaudePerplexityGrok

A service report is the document a technician fills in at the end of each visit: where they went, what they found, what they did, what materials they used, how long it took and who signed off on it. It’s used to invoice, to answer a complaint and to know whether someone has to go back. In this article you’ll find which fields it should include, which records Spanish law requires for thermal installations and fluorinated gases, the most common mistakes and a free Excel and PDF template.

What a service report is

At a maintenance, HVAC or installation company, every job leaves two documents behind. They’re often confused, but they aren’t the same:

Work orderService report
When it’s doneBefore the visitDuring or at the end of the visit
Who does itThe officeThe technician
What it recordsWhat needs to be done: customer, equipment, problem, urgencyWhat was done: work, materials, hours and outcome
What it’s forSending the technician out with the informationInvoicing, backing up the work and keeping a history

The work order opens the job and the service report closes it. If the report says “pending,” the work order stays open and there’s a second visit ahead.

Service requestWork orderVisitService reportInvoice, historyIf it’s left pending:a second visit
From the service request to the invoice. The report decides whether the job is closed or someone has to go back.

What a service report is for

  • Invoicing. The hours and materials on the report are the basis of the invoice. If it isn’t on the report, it doesn’t get billed.
  • Answering a complaint. If the customer says the technician didn’t show up, or was only there for an hour, the signed report is the proof.
  • The equipment’s history. The next time that chiller fails, the technician will know what was done and what was replaced.
  • Complying with the law. Thermal installations and equipment with fluorinated gases have mandatory records, and the report is where they come from. More on that below.
  • Knowing whether to go back. A report that says “part needed” is a second visit someone has to schedule.

What a service report should include

There’s no single official form. These are the fields none should be without, plus the ones worth adding if you work with maintenance contracts:

FieldWhyEssential
Report and work order numbersLinks the report to the service request and the invoiceYes
Customer and addressWhere the work was done, not where it’s billedYes
EquipmentType, make, model and serial or asset numberYes
Date, arrival and departure timesThe basis for billable hours and for a contract’s response timesYes
TechnicianWho did the work and with what certificationYes
Problem reportedWhat the customer said, to compare with what was foundYes
Work performedWhat was done, in detail; “checked, all fine” won’t doYes

This is what a properly filled-in report looks like, for a typical chiller breakdown:

What Spanish law says about service reports

The law doesn’t require a document called a “service report.” But it does require certain records that, in practice, are filled in from what the report says. The three that matter most to a maintenance company in Spain are these:

RegulationWhat it requiresKept for
RITE (Spain’s Regulation on Thermal Installations in Buildings), Article 27Every thermal installation has a record of maintenance operations and repairs. It’s kept by the maintenance company, which is responsible for what’s entered, and it’s part of the Building Logbook.5 years
Regulation (EU) 2024/573 on fluorinated gasesFor equipment subject to leak checks, a record of each intervention: type and amount of gas added or recovered, and who did it. The company that does the work keeps a copy.5 years
Spanish Workers’ Statute, Article 34.9The daily record of each technician’s working hours, with start and end times. It isn’t the service report, but many companies take it from the daily report.4 years
A summary to help you find your way, not legal advice. What applies to each installation depends on the equipment and the contract: check with your trade association or your advisor.

The practical upshot is simple. If the report records the equipment, the work and the gas in detail, the record fills itself in. If it says “inspection, all OK,” someone will have to reconstruct it when it’s requested.

Daily service report or one per job

There are two ways to organize it, and many companies use both:

  • One report per job. One per visit, tied to its work order. This is the one used for invoicing and for the equipment’s history.
  • Daily report. One sheet per technician per day, with all their visits, travel and hours. It’s useful for tracking hours and for the working-time record.

If you can only have one, make it the per-job report. The daily one can be built by adding up that day’s reports; it doesn’t work the other way around.

Service reports on paper, in Excel or with an app

Before buying a service report app, check whether your ERP or management software already includes one. Many do, and a report kept outside the ERP is one more piece of data someone has to retype.

The seven most common mistakes

  1. “Checked, all OK.” It doesn’t say what was checked or what condition it was in. It’s useless as a record or as a defense.
  2. No arrival or departure time. Without them, there’s no way to bill hours or prove a response time.
  3. Materials without a part number. “A filter” can’t be billed or restocked.
  4. “Pending” with no reason. If it doesn’t say what’s missing, nobody at the office knows what to order or when to go back.
  5. No work order number. The report floats on its own and nobody knows which service request it came from.
  6. No customer sign-off. If there’s a complaint, it’s your word against theirs.
  7. It arrives days late. Every day that passes is another day without invoicing and with more things forgotten.

The report starts with the service request

Many reports end up “pending” because of something that happened before the visit: the service request came in incomplete. The technician didn’t know what equipment it was, the make or what alarm it was showing, and went without the part. It’s the most expensive second visit, the one the office could have prevented.

That’s why the report and the work order are two ends of the same job. The more complete the service request, the more reports get closed the first time. That’s exactly the work an AI agent does in the office, and we cover it in AI agents for maintenance companies.

In short

The service report closes what the work order opened: what was done, with what materials, how long it took and whether someone has to go back. Properly filled in, it’s used to invoice, to defend against a complaint and to keep the records required by the RITE and the fluorinated gas rules.

The essentials: work order number, equipment, hours, detailed work, materials with part numbers, status with a reason and the customer’s sign-off.
