Work Order Template: Format, Fields and Examples
A practical work order template: the fields every job ticket needs, a filled example with labor and parts math, and how to turn a finished job into an invoice.
Quick answer: A work order template is a standard form that authorizes and tracks a job. It should include a work order number, requester and site details, a clear description of the task, priority and due date, the assigned technician, labor hours, parts used, costs, and sign-off fields for completion and customer approval.
Whether you run a maintenance team, a plumbing business or a print shop, jobs fall through the cracks when instructions live in phone calls and text messages. A work order puts everything about a job on one page: what to do, where, for whom, by when, and what it took to finish. This guide walks through the fields a work order template needs, shows a filled example with labor and parts arithmetic, and explains how a closed work order turns into an accurate invoice.
What is a work order?
A work order is a document that authorizes a specific piece of work and records its progress. You will also see it called a job order, job ticket, work ticket or service ticket. It usually starts as a request, such as a tenant reporting a leaking tap or a customer approving a repair, and moves through stages: open, assigned, in progress, completed and closed.
Work orders sit between the sales documents and the billing documents. A customer might accept your job estimate or send you a purchase order; you open a work order so the job gets done; and when it is finished, you invoice from it. For how buyer-issued orders fit in, see our purchase order template guide.
Work order vs purchase order vs invoice
| Document | Who issues it | When | Main purpose |
|---|---|---|---|
| Estimate or quote | Seller | Before the job | Proposes scope and price |
| Purchase order | Buyer | Before the job | Orders goods or services at agreed terms |
| Work order | Seller or internal team | Before and during the job | Authorizes, assigns and records the work |
| Invoice | Seller | After the job or a milestone | Requests payment for work done |

Fields to include in a work order template
Header and reference details
- Work order number, unique and sequential, such as WO-2026-0148
- Date opened and requested completion date
- Customer or requester name, phone and email
- Job site address, plus access notes such as gate codes or contact on site
- Customer PO or reference number, if the customer issued one
Job details
- Work type: repair, preventive maintenance, installation, inspection, emergency
- Priority: low, normal, high or emergency
- Description of work: what is wrong or what is needed, in specific terms
- Asset or equipment: make, model, serial or asset tag
- Assigned to: technician or crew, and scheduled date
- Safety notes: permits, protective equipment, lockout requirements
Completion and cost details
- Work performed: what was actually done and any follow-up needed
- Labor: technician, hours and rate
- Parts and materials: description, quantity, unit cost
- Other charges: trip or call-out fee, equipment rental, disposal
- Totals: subtotal, tax if applicable, total
- Sign-off: technician signature and date, customer signature and date
The description field deserves the most care. A useful description answers four questions: what is the problem or task, where exactly is it, what has already been tried, and what does "done" look like. "Rooftop unit 2 above reception blows warm air since Monday; breaker reset did not help; restore cooling and report on unit condition" gives the technician everything they need before they arrive, and it gives you a clear standard to bill against.
For maintenance on machinery, the safety field is more than a formality. In the US, OSHA's control of hazardous energy (lockout/tagout) standard applies to many servicing and maintenance jobs, and noting the required procedure on the work order helps technicians follow it.
Filled work order example
Here is an illustrative work order for an HVAC repair. The rates and prices are examples only.
| Field | Entry |
|---|---|
| Work order no. | WO-2026-0148 |
| Customer | Greenway Dental, 210 Park Road |
| Customer PO | GD-7731 |
| Type and priority | Repair, high |
| Description | Rooftop unit 2 not cooling; check compressor start components |
| Assigned to | J. Okafor, 4 November 2026 |
| Work performed | Replaced failed run capacitor and pitted contactor; tested cooling, normal |
The cost section:
| Line | Qty | Rate | Amount |
|---|---|---|---|
| Labor, HVAC technician (hours) | 3.5 | $95.00 | $332.50 |
| Run capacitor | 1 | $48.00 | $48.00 |
| Contactor | 1 | $62.00 | $62.00 |
| Trip charge | 1 | $75.00 | $75.00 |
| Total before tax | $517.50 | ||
Check the arithmetic: 3.5 × $95 = $332.50; $332.50 + $48 + $62 + $75 = $517.50. Whether sales tax applies to labor, parts or both depends on your state, so confirm the rule before you invoice. The sales tax calculator helps once you know the rate.
How to turn a work order into an invoice
- Close the work order first. Make sure actual hours and parts are recorded and the customer has signed off.
- Copy the lines across. Each labor and parts line on the work order becomes a line on the invoice, with the same quantities and rates. Our guide to an itemized invoice explains how much detail to show.
- Reference the work order and PO. Put the customer's PO number in the PO field and the work order number in the notes, so accounts payable can match everything. See where to put a PO number on an invoice.
- Apply tax correctly. Use the rate that applies to the job's location and taxable items.
- Create the PDF. In our free invoice generator, add the lines, enter the PO number, set your tax rate, put "Work order WO-2026-0148" in the notes and download the invoice. The tool creates invoices only; keep the work order itself in your spreadsheet or job software.
If the job grew beyond what was approved, do not just add the extra hours to the invoice. Get the change approved first, as explained in our guide to scope creep and change orders.
Work order statuses and workflow
A work order is only useful if everyone knows where it stands. Most teams use a short list of statuses and move each order through them in order:
| Status | Meaning | Who acts next |
|---|---|---|
| Requested | A need has been reported but not approved | Supervisor or office |
| Open | Approved and waiting to be scheduled | Scheduler |
| Assigned | Technician and date set | Technician |
| In progress | Work started; may be on hold for parts | Technician |
| Completed | Work done, hours and parts recorded, customer signed | Office |
| Closed | Reviewed and invoiced, or closed as internal work | Nobody; archived |
Keep "completed" and "closed" separate. The gap between them is where you check the paperwork and raise the invoice. A weekly review of completed-but-not-closed orders is a simple habit that stops finished jobs from going unbilled.
Paper, spreadsheet or software?
Paper forms in carbon-copy books still work for very small operations: the technician fills one in on site and leaves a copy with the customer. They are cheap but hard to search and easy to lose. Spreadsheets suit small teams: one tab as a printable work order form and another as a log, with formulas multiplying hours by rate and quantity by unit price. Maintenance or field service software adds mobile forms, photos, scheduling, asset history and automatic reminders for preventive maintenance. Whatever you choose, the fields in this work order template stay the same, so start with the format and move to software only when volume justifies the cost.
Work order numbering and tracking
Use a simple, sortable scheme: a prefix, the year and a sequence, such as WO-2026-0148. Never reuse a number, even for cancelled jobs; mark them cancelled instead. If you want a consistent format across work orders and invoices, the invoice number generator can produce sequences with your own prefix.
Keep a log with one row per work order: number, customer, date opened, technician, status, date closed and invoice number. That log shows at a glance which jobs are finished but not yet billed, which is one of the most common sources of lost revenue in service businesses.
Work order templates by industry
- Facilities and property maintenance: emphasize asset ID, location, priority and preventive maintenance schedules.
- HVAC, plumbing and electrical: emphasize labor hours, parts, permits and customer sign-off; see our HVAC invoice template for the billing side.
- Auto repair: emphasize vehicle details, mileage, customer authorization of the estimate and approval of any extra work.
- Printing and manufacturing: emphasize specifications, quantities, materials, proofs and deadlines.
- IT and managed services: emphasize ticket numbers, devices, time spent and resolution notes.
Common work order mistakes
- Vague descriptions. "Fix AC" forces the technician to call back. Describe the symptom, the location and any history.
- Not recording actual time. Estimated hours on the work order are not what you bill on time-and-materials jobs.
- Missing customer authorization. Starting without approval invites disputes, especially when costs exceed the estimate.
- Closing without invoicing. Link every closed work order to an invoice number in your log.
- Parts used but not listed. Small parts add up; record every item taken from the van or stockroom.
- No photos or notes. Before-and-after notes help with warranty claims and repeat visits.

Frequently asked questions
What is a work order?
A work order is a document that authorizes and describes a specific job, such as a repair, installation or maintenance visit. It records who requested the work, what needs to be done, where, by when and by whom, and later what labor and parts were used. It is also called a job order, job ticket, work ticket or service ticket, depending on the industry.
What is the difference between a work order and an invoice?
A work order is created before or during the job to authorize and track the work. An invoice is created after the work, or a stage of it, is done, and asks the customer to pay. In most service businesses the completed work order, with actual hours and parts, becomes the source data for the invoice, and the invoice quotes the work order number as a reference.
What is the difference between a work order and a purchase order?
A purchase order is issued by a buyer to a seller to order goods or services at agreed prices, and it often works as a contract once accepted. A work order describes the job itself and is mainly used to assign, schedule and record the work. A customer might send you a purchase order, and you would then open a work order for your technician to carry it out.
Who creates a work order?
It depends on the setup. In maintenance teams, a staff member or tenant submits a request and a supervisor turns it into a work order. In contracting and field service, the office or the business owner usually creates the work order after the customer approves an estimate. Either way, one person should be responsible for opening, assigning and closing each order.
Is a work order legally binding?
An internal work order is mainly an operational document. A customer-facing work order that describes the job and price and is signed by the customer can serve as evidence of an agreement, and in some trades it works much like a short contract. Rules vary by jurisdiction and industry, so for larger jobs use a written contract or signed estimate as well.
What are the main types of work orders?
Common types include preventive maintenance (scheduled servicing), corrective or repair work, emergency work, inspections, installations and general service requests. Many teams add a priority level such as low, normal, high or emergency. Recording the type helps you analyze where time and money go, for example how much of your maintenance budget is reactive repair rather than planned servicing.
Can I create a work order in Excel or Google Sheets?
Yes. A spreadsheet works well for small teams: one sheet as the printable work order form and another as a log with one row per work order, its status and dates. Formulas can total labor hours multiplied by rate and parts quantities multiplied by unit price. Once volume grows, maintenance or field service software adds scheduling, mobile access and photo uploads.
Should the customer sign the work order?
It is good practice. A signature before work starts shows the customer authorized the job, and a signature on completion confirms the work was done and the hours and parts were accepted. That second signature is especially useful for time-and-materials jobs, because it reduces disputes when the invoice arrives and the customer questions the hours or parts used.
