Finish the task
Make this invoice in ABN Invoice
Answer the invoice tampering payment fraud Australia question, open the matching live workflow, review the customer copy and export the finished document without repairing a copied template.
Enter changed bank-detail response, word and ordinary pdf limits, independent proof comparison, preview the document, and export a PDF or phone-friendly image.
Quick answer
Can a Word or PDF invoice prove that it has not been changed?
An editable Word file should not be treated as a final payment record. A normal exported PDF is harder to change accidentally, but without a trusted certificate-based digital signature or another independent verification path, the file alone does not prove that it is unchanged. If bank details differ unexpectedly, pause, contact the issuer through a separately verified channel and preserve both copies before payment.

Source-grounded notes
What this page is grounded on
- Australian cyber guidance treats invoice and bank-detail substitution as a business email compromise risk, so the response focuses on independently verifying payment changes rather than blaming one file type.
- The page distinguishes an ordinary exported PDF, a certificate-signed PDF and a Peppol eInvoice. ABN Invoice does not claim to provide certificate signing or Peppol eInvoicing.
- ABN Invoice's verification mark is described only as a comparison with the issuer's saved original key facts, not proof of tax compliance or factual truth.
Key facts
What to know before choosing this workflow
These short facts are visible to readers and summarize the page without implying ATO approval, tax advice, or accounting software replacement.
- Common fraud path
- Business email compromise can be used to substitute bank or contact details on an otherwise believable invoice.
- Word boundary
- Microsoft says Mark as Final is not a security feature, and recipients can remove the status and edit the file.
- PDF boundary
- A normal PDF is a final-looking format, but trusted certificate validation or another comparison path is needed to establish document integrity.
- ABN Invoice verification
- VIP can place a verification mark and proof ID that compares key document facts with the issuer's saved original record; it is not a certificate-based digital signature and does not prove the original facts were true.
What you enter
- Changed bank-detail response
- Word and ordinary PDF limits
- Independent proof comparison
What you leave with
Export PDF or image files, save history, mark invoices sent or paid, and use archive tools when records need to be handed to an accountant.

Best fit for this search
Stop and verify unexpected changes
Do not rely on the contact details inside the suspicious message. Confirm changed bank details through a previously known phone number or another separately verified channel.
- Pause payment
- Contact the bank if money moved
- Preserve original and suspicious copies
Send a reviewed final file
Keep the editable Word or spreadsheet as a working file when needed, but send the reviewed final PDF or image to the customer unless collaboration specifically requires editing.
- Do not email the editable master by default
- Recheck bank details
- Use a unique invoice number
Add a verification path
ABN Invoice's verification mark can help a recipient compare key facts with the issuer's saved original. High-assurance workflows may instead require certificate-based digital signatures or controlled eInvoicing.
- Proof ID comparison
- Certificate signature when required
- Peppol eInvoice is not an emailed PDF
Questions people ask before making this invoice
These are practical questions that show up around ABN, GST, phone invoicing, and small-job invoice records.
What should I do if an invoice has been tampered with?
Pause payment, independently verify the issuer and bank details, preserve the messages and files, contact the bank quickly if payment occurred, notify affected parties and use ReportCyber or Scamwatch where appropriate.
Should I send a Word version of an invoice?
Send the reviewed final PDF or image rather than the editable working Word file unless the recipient genuinely needs to collaborate on the document.
Is every PDF tamper-proof?
No. A normal PDF is not the same as a certificate-signed PDF. Treat unexpected bank-detail changes as a separate verification event.
Does the ABN Invoice watermark prove tax compliance?
No. The verification mark compares key document facts with the issuer's saved original. It does not verify the truth of the original ABN, GST status, transaction or payment details.

Does the ABN Invoice watermark prove tax compliance?
No. The verification mark compares key document facts with the issuer's saved original. It does not verify the truth of the original ABN, GST status, transaction or payment details.
Can I start without creating an account?
Yes. The live maker opens without sign-up. Free sign-in is useful later for cloud History and repeat records.
Can I create GST and no-GST documents?
Yes. Choose the line-item treatment that matches the accurate facts entered by the user.
Can I export PDF and image files?
Yes. Review the customer-facing preview, then export PDF for email or an image for phone-first sharing.
Does ABN Invoice replace accounting or tax advice?
No. It creates invoice, receipt and quote documents; it does not decide tax, legal, accounting or financial obligations.
Does the tool verify every fact I enter?
No document maker can prove every ABN, GST status, customer, transaction or payment detail. The user must review the facts before sending.
