Payment instructions: add your verified business account details and ask the client to use INV-205 as the reference. Tax must be determined before sending.

What the annotations mean

  • Q-201: links the invoice to the accepted base scope.
  • Separate quantities and rates: let the customer check labour and materials.
  • CO-01: identifies the extra work and its approval. Keep the written approval with the job record.
  • Due date: repeats the terms agreed before work started.

If a deposit has already been paid

If this single $1,400 invoice has a recorded $200 payment, its outstanding balance before any applicable tax is $1,200. If the $200 was instead charged on a separate deposit invoice, the new remaining-scope invoice should charge $1,200 before applicable tax: total project billing is still $1,400. Do not issue two invoices that both charge the full job value.

  • ✓ Describing work only as per contract, with no stage, work detail or approval reference

Frequently Asked Questions

What should be on a contractor invoice?

Your business details and license number where required, the client and job address, an invoice number and date, labour and materials as separate lines, any approved change orders with their dates, earlier billing and recorded payments clearly identified, and the balance due with payment terms.

How do I invoice for a change order?

Put it on its own line, describe the change in plain words, and reference the date the client approved it. Never fold it into an existing labour line — a change the client cannot identify is a change they will question.

Should contractors invoice progressively?

Progress invoices can suit longer jobs when agreed milestones or measured work make billing clear. Follow the contract and applicable payment rules; not every project uses the same schedule.

Prepare the right invoice for this stage

Choose the agreed charging basis: completed hours and materials, a fixed fee or a milestone. Match the descriptions to the approved work and make the current amount due clear.

Do not deduct an unpaid deposit request as though it were cash received. Keep the original invoice reference when following up an outstanding stage.
