Support

Write to us from the Google account you use in the sheet.

Email support@abnformula.com. Include the approximate time of the error. If one ABN misbehaved, include that number. Please do not send a full client list.

Try this first

• Open the sidebar once. Until you do, a formula says “Open ABN Formula → Open sidebar once to authorise lookups.” That step grants permission and stores a token for the sheet.
• Use plain text. Format the ABN column as plain text. Google Sheets will otherwise drop a leading zero.
• Invalid ABN. The checksum failed. The number was not sent to the register and did not use your allowance.
• Limit reached. The free plan is 50 different ABNs per month, in Sydney time. The same ABN again is free. You can upgrade in the sidebar.
• An old name. Results can be 24 hours old. “Checked at” is when the register was asked, not when you last opened the file.

Delete your data

Use ABN Formula, then the sidebar, then Delete my data. That removes your email, plan link and the list of ABNs counted this month. Public register rows already saved can remain for up to 24 hours, because they are not your private records.

If you cannot open Google Sheets, email privacy@abnformula.com from that Google account with the subject “Delete my ABN Formula data”. A request from a different address is not enough.

Remove one saved ABN

If a record should not be shown, including when the Australian Business Register has withdrawn it, email the 11-digit ABN to privacy@abnformula.com with the subject “Purge cached ABN”.

We cannot change the official register. If an ABN is wrong at the source, update it with the Australian Business Register.
