A B2B contractor invoice tied to a purchase order and project milestone — common for IT contractors, consultants, and trade subcontractors.
Use the example above as a reference, then enter your actual business, customer and job details here. Start without an account; downloads follow the free-tool limits. Saving, tracked sending and reminders require an account.
They are often the same legally (sole trader ABN). Contractor invoices typically include PO numbers, project references, and longer payment terms for B2B clients.
Use the template as a starting layout, then replace its example information with the actual agreed work. The details below help you decide what to enter and what to check before sending.
Decide whether the job is fixed-price, time-and-materials or milestone-based before you invoice it. A fixed-price invoice names the deliverable; a time-and-materials invoice shows measurable quantities. If the client asks for extra work, record the new scope and approval rather than silently changing the original price.
Include the job number, client purchase order, service location and agreed billing stage. Check the legal billing name and delivery contact against the accepted work. Keep the accepted quote, recorded hours or stage sign-off, and approval for additional work available to resolve questions. An invoice records the charge; it does not replace the underlying approval or supporting documents.
This time-and-materials example separates hours from materials. For a fixed-price job, use the agreed stage amount instead of presenting a second hourly calculation that could contradict the quote.
| Description | Quantity | Rate | Amount |
|---|---|---|---|
| Installation labour — approved additional work | 6 | 80.00 | 480.00 |
| Materials — itemised on attached schedule | 1 | 220.00 | 220.00 |
| Example subtotal | 700.00 | ||
Using a new invoice number for every reminder makes one debt look like several. Keep the original number when following up. When creating the next milestone, use a new number and make clear which work it covers.
Check the balance against recorded payments before sending a reminder. A completed project can still have unpaid earlier stages, even when there is nothing left to invoice. Review both the unbilled work and the outstanding invoices before closing the job.
The free browser tool prepares the document. Saving customers, sending tracked invoices and managing reminders require an account and are subject to plan limits. Payment status needs accurate payment records; an invoice view alone does not confirm payment.
