Site billing vs client billing: what should homeowners check? Site billing usually tracks measured work and costs on site. Client billing is the payment claim presented under the agreed contract. Before paying, reconcile the claimed quantity, agreed rate, completed work, previous payments and approved variations. The contract determines the exact billing rules. What is the difference?: A site record can capture subcontractor work, material receipts and measured quantities. A client bill brings together the amounts being claimed from the owner. These records serve different purposes, so their totals should not be assumed to match without reconciliation. Agree at the outset which documents support each payment. Check quantities before comparing totals: Ask for a measurement sheet linked to the relevant bill item and drawing revision. Check the unit: a length, an area and a volume cannot be compared directly. For concealed work, retain inspection records and dated photographs before it is covered. Photographs support the record but do not replace measurements. Reconcile rates, changes and previous payments: Compare the claimed rate with the accepted quotation or bill of quantities. List changes separately, with the reason, agreed price and approval. Then check cumulative work, amounts already certified, advance recovery and any contractually agreed retention. This helps distinguish the value of work from the amount currently due. A useful payment review routine: Keep one dated register containing the claim, supporting measurements, reviewer comments, approved amount and payment reference. Ask the agreed project representative to resolve discrepancies before approval. A regular review is easier to follow than trying to reconstruct several months of bills at once.

Check quantities before comparing totals
Ask for a measurement sheet linked to the relevant bill item and drawing revision. Check the unit: a length, an area and a volume cannot be compared directly. For concealed work, retain inspection records and dated photographs before it is covered. Photographs support the record but do not replace measurements.
Reconcile rates, changes and previous payments
Compare the claimed rate with the accepted quotation or bill of quantities. List changes separately, with the reason, agreed price and approval. Then check cumulative work, amounts already certified, advance recovery and any contractually agreed retention. This helps distinguish the value of work from the amount currently due.
A useful payment review routine
Keep one dated register containing the claim, supporting measurements, reviewer comments, approved amount and payment reference. Ask the agreed project representative to resolve discrepancies before approval. A regular review is easier to follow than trying to reconstruct several months of bills at once.

Your next questions, answered.
Is a material receipt enough to approve a bill?
Not always. A receipt records a purchase or delivery; entitlement to payment depends on the contract and the evidence required for that bill item.
Should a client pay only for completed work?
Payment arrangements vary. Some contracts include advances or materials on site. Follow the agreed terms and check the supporting records for each claim.
Who should check construction quantities?
Agree a competent reviewer with the required quantity-surveying or project experience. Establish the review responsibility before the first bill.
