What Is a Work Order? A Complete Guide for Small Businesses
A work order is a formal document that authorizes and outlines a specific job, task, or service to be performed. It serves as a communication tool between the person requesting work (the customer or manager) and the person or team completing it (the technician, contractor, or service provider). Work orders contain all the details needed to execute a job, including what needs to be done, where, when, by whom, and at what cost.
For small businesses in service industries like HVAC, plumbing, electrical, roofing, property management, and appliance repair, work orders are essential operational documents. They transform verbal requests and informal agreements into documented, trackable records that protect both the business and the customer.
Work Order vs. Purchase Order vs. Invoice
These three documents serve different purposes in the business workflow, and understanding the distinction helps you use each one effectively:
| Document | Purpose | When Used | Key Info |
|---|---|---|---|
| Work Order | Authorizes and details work to be done | Before and during the job | Scope, materials, labor, schedule |
| Purchase Order | Authorizes purchase of goods/services from a vendor | When ordering supplies or hiring subcontractors | Items, quantities, prices, delivery terms |
| Invoice | Requests payment for completed work | After the job is done | Final costs, payment terms, due date |
A typical workflow goes: a customer request generates a work order, which may trigger purchase orders for materials, and once the work is completed, an invoice is sent for payment.
Types of Work Orders
Work orders fall into several categories based on the nature and urgency of the work:
1. Preventive Maintenance Work Orders
Scheduled maintenance performed at regular intervals to prevent equipment failures. Examples include HVAC filter replacements, vehicle oil changes, and routine building inspections. These are typically recurring and planned well in advance.
2. Corrective (Reactive) Work Orders
Created in response to a problem or failure that has already occurred. A broken pipe, a malfunctioning air conditioner, or a power outage would all generate corrective work orders. These are unplanned and often require faster turnaround.
3. Emergency Work Orders
The highest priority category, reserved for situations that pose immediate safety risks or significant property damage. Gas leaks, electrical fires, flooding, and structural damage fall under emergency work orders. These bypass normal scheduling and are addressed immediately.
4. Inspection Work Orders
Used for scheduled inspections that evaluate the condition of equipment, facilities, or systems. Building code inspections, safety audits, and equipment certifications are common examples. These may lead to corrective work orders if issues are found.
