A Work Order Number (WO Number) is a formal document reference number issued by a client to a contractor, authorizing them to begin a specific service or construction task. In government and B2B contracts, it is the official “Green Signal” after you win a tender.
When you ask “what is Work Order Number,” you are referring to the contract ID against which you will raise your invoices. Unlike a Purchase Order (PO) which is usually for goods (products), a Work Order is usually for services (labor, maintenance, construction).
What Does Work Order Number Mean?
It represents a legal contract. It outlines:
- Scope of Work: What exactly needs to be done.
- Timeline: Start and End dates.
- Value: The total financial limit agreed upon (from the Tender BOQ).
- Terms: Payment schedule and penalties.
Why Work Order Number is Important
- Billing: You cannot submit a bill without quoting the WO Number. The finance department needs it to allocate funds.
- Experience Certificate: To bid for future tenders, you need to show “Past Experience.” Copies of completed Work Orders are the primary proof.
- Compliance: You need this number to apply for a Labour License for that specific site or to generate a Project ID for PF compliance.
Where is Work Order Number Used?
- Invoices: “Ref: Work Order No. 1234”.
- Gate Passes: For material and labor entry into the site.
- Completion Report: The final completion certificate will reference this WO number.
