What is a work order?
A work order is a document that describes a specific job to be done: what the work is, where and when it will happen, the labor and materials involved, the estimated cost and who approved it. It is used by tradespeople, repair shops, maintenance teams and field-service businesses to make sure everyone agrees on the scope before work begins.
A work order sits between a quote and an invoice. A quote offers a price; a work order confirms the job and authorizes the technician to start; an invoice requests payment once the work is done.
When do you need a work order?
- Home services: plumbing, electrical, HVAC, roofing, painting, landscaping and handyman jobs.
- Repair shops: auto, appliance, electronics and equipment repair, where the customer must approve the work. For billing after a car repair, see the auto repair invoice template.
- Property maintenance: landlords and facility managers sending jobs to staff or contractors.
- Internal jobs: assigning tasks to your own team with a clear record of what was requested.
Work order vs job sheet vs service ticket
Different trades use different names for the same idea. A job sheet, service ticket, service order or repair order all describe the work to be done and record approval to do it. Whatever you call it, the document should answer the same questions: what is being done, where, when, at what estimated cost, and who said yes. If your industry uses a different name, simply change the document title in the generator.
What to include on a work order
- Work order number and date issued
- Your business name, contact details and license number if applicable
- Customer name, phone and the job site address
- Scheduled date (and time window) for the work
- A clear job description: the problem and what will be done
- Itemized labor (hours and rate) and materials or parts (quantity and price)
- Estimated total, including tax if applicable
- Terms: payment timing and the rule for additional work
- Customer authorization signature and date
Worked example
Northside Plumbing is booked to replace a leaking water heater. Before starting, the technician writes work order WO-1187 and the homeowner signs it:
| Task / material | Qty | Rate | Amount |
|---|---|---|---|
| Remove and dispose of old water heater | 1 | $120 | $120.00 |
| Install new water heater (labor, hours) | 3 | $95 | $285.00 |
| 50-gallon gas water heater | 1 | $849 | $849.00 |
| Fittings, flex lines and venting kit | 1 | $68 | $68.00 |
| Estimated total | $1,322.00 | ||
During the job the technician finds a corroded shut-off valve. Because the work order says extra work needs approval, he asks first, adds the valve after the homeowner agrees, and then turns the completed work order into an invoice.
Tips and common mistakes
- Describe the scope precisely. "Fix heater" invites disputes; "Replace 40-gallon gas water heater with 50-gallon unit, reuse existing gas line" does not.
- Get the signature before starting. Authorization protects you if the customer later disputes the work or price.
- Separate labor from materials. Customers trust itemized pricing, and it makes changes easier to price.
- Put a change rule in writing. State that additional work requires approval, and record any changes on the order.
- Number every order. Sequential numbers let you track jobs from booking to invoice to payment.
- Set payment terms upfront. If payment is due within a set number of days, use the payment due date calculator to get the date right.

Frequently asked questions
What is the difference between a work order and an invoice?
A work order describes and authorizes a job before or during the work, while an invoice requests payment after the work is complete. Many businesses convert a finished work order into an invoice.
Is a work order the same as a quote?
Not quite. A quote is an offer the customer can accept or decline; a work order confirms the job is going ahead and records the customer's authorization.
Should the customer sign the work order?
Yes. A customer signature authorizing the work and the estimated cost is your best protection against disputes about scope or price.
Can I use this for internal maintenance jobs?
Yes. Enter your department or team as the service provider and the requester as the customer, and use the line items to list tasks and parts.
