What is a work order?
A work order is a document authorizing work to be done. It describes the task, the location, any materials, and who approved it — the green light that turns an approved estimate into scheduled work. Many businesses number work orders to track jobs from authorization to invoice.
In practice
A property manager emails work order WO-118 to an HVAC contractor: 'Replace blower motor, Building C, authorized by Dana, not to exceed $900.' The tech completes it, references WO-118 on the invoice, and the manager can match all three documents.

Who issues a work order?
Usually the client or their manager — it's their authorization for you to proceed. Contractors also issue internal work orders to schedule their own crews.
What's the difference between a work order and a purchase order?
A work order authorizes services or repairs; a purchase order authorizes buying goods. They play similar roles on opposite sides of a transaction.
Should a work order include a price?
Include at least a cap ('not to exceed $900') or the agreed estimate reference. Open-ended work orders are where billing disputes are born.
