Subcontractor Billing and Work Orders: Keeping Payments Tied to Progress

On most projects, a large share of the work is done by subcontractors: masons, electricians, plumbers, tiling crews. Paying them well means paying the right amount, for work that was actually done, against an agreed scope. When this runs on phone calls and notebooks, disputes follow.

Start with a Proper Work Order

A work order is the document that tells the subcontractor what to do and on what terms. A useful one includes:

• The scope, broken into items with units and quantities.
• The agreed rate for each item.
• The measurement method, so both sides count work the same way.
• Payment terms, and any retention or advance arrangements.
• The link to the matching BOQ items, so the work order cannot quietly exceed the budget.

Check the Budget Before You Issue

The contract BOQ carries the money available for each item. A work order for a larger quantity or a higher rate than the BOQ allows is a loss written in advance. Check the budget at issue time, not at billing time.

Bill Against Measured Progress

1. The subcontractor submits a progress claim for the work done.
2. The site engineer measures it and records the approved quantity.
3. The system compares cumulative quantity with the work order quantity.
4. The approved amount, less any retention or advance recovery, becomes the payable bill.

Where Things Go Wrong

• Verbal scope changes that never reach the work order.
• Claims paid before measurement.
• No cumulative check, so the claimed quantity passes the work order total.
• Invoice status is unclear, so subcontractors keep phoning to ask where their payment is.

Making It Visible to the Subcontractor

A portal where subcontractors see their work orders, submit claims and watch invoice status cuts a surprising number of calls. VISWOX ERP provides this, with budget enforcement before approval. For related reading, see RA bills and retention and labour and overhead tracking.

Summary

• Issue a clear work order tied to BOQ items and rates.
• Check the budget before issuing, and measure before paying.
• Give subcontractors visibility into claim and invoice status.
