Bulk ABN check: work through your supplier list

We don't have a bulk upload, the checker takes one ABN, ACN or business name at a time, so here's a quick routine for checking multiple ABNs and keeping a clean record.

Speed comes from the routine, not from skimming

Without a bulk upload, your time goes into reading. The useful detail on each result sits in the dates and the names, so that's where your eyes should land.

Active isn't the whole story. Check the date beside the status, because a recent change is worth a second look.

If the invoice charges GST, the result should show GST registration with a start date on or before the invoice date. If it says "Not registered for GST", flag the row.

Compare the names last. An invoice often uses a business name while the result leads with the legal name, so look through the registered business names before you call it a mismatch.

What to record for every supplier you check

One row per supplier, the same seven columns every time. Five come straight off the result. The last two are dates that make your record useful later.

  1. ABN

    Copy the formatted ABN from the result, not from the invoice. If the two differ, that's your first flag.

  2. ABN status and its date

    Write down the status and the date it took effect. A recent date is worth a closer look before you pay.

  3. GST and its start date

    Note the date GST registration started, or record "Not registered for GST". Compare it with the date on the invoice.

  4. Entity type

    Sole trader, company, partnership or trust. It tells you what kind of name to expect at the top of the result.

  5. Name shown

    Record the legal name and any registered business name that matches your invoice. Note which one the invoice uses.

  6. Retrieval date

    Copy the date from the source line at the bottom of the result. It shows how fresh the register record was.

The bulk ABN check routine, step by step

Same steps in the same order for every supplier. That's what keeps a long list quick without cutting corners.

Use the pre-payment checklist

  1. Sort the list first

    Put new suppliers and anyone you're about to pay at the top. Regular suppliers you checked recently can wait for the next round.

  2. Copy the ABN from the invoice

    Take it from the latest invoice. If there's no ABN at all, note that on the row before you go any further.

  3. Search one supplier

    Paste the ABN, ACN or business name into the checker. It tests the check digits as you type and tells you if a number can't be a real ABN or ACN.

  4. Work down the result in order

    Status, then GST, then entity type, then names. Keep the invoice beside the screen so each line gets compared, not just glanced at.

  5. Record it before you move on

    Fill in the row while the result is still on screen, including the retrieval date from the source line. Then clear the box and start the next supplier.

  6. Flag, don't fix, on the run

    If something doesn't match, mark the row and keep going. Finish the list, then work through your flags one by one.

  7. Set the next check date

    Recheck when a supplier is new, before their first payment, whenever their details change and before the financial year ends. Note the next trigger on the row.

Frequently Asked Questions

Can I upload my supplier list?
No. We don't have a bulk upload or any file import. The checker takes one ABN, ACN or business name at a time. The routine on this page keeps that quick, and your own record sheet does the job a bulk report would.
The name on the result doesn't match the invoice. What now?
First look through the registered business names on the result. Invoices often use a trading name while the result leads with the legal name. If the invoice name isn't there at all, flag the row and ask the supplier on a number you already have before you pay.
A supplier's status has changed since my last check. What does that mean?
Record the new status and the date it took effect. If the ABN now shows as cancelled, hold the payment and ask the supplier about it. Our guide to ABN status explains each status in plain words.
The invoice has no ABN on it. What should I do?
Ask the supplier for it before you pay. The ATO says that if a supplier doesn't give an ABN and the payment is more than excluding GST, you generally must withhold 47 per cent and pay it to the ATO, unless an exception applies. Confirm on the ATO website or with your accountant.
How often should I recheck a supplier?
A sensible pattern is four moments. Check when a supplier is new. Check again before their first payment. Check whenever their bank details, name or ABN on an invoice change. Then run the whole list once more before the financial year ends.
How current is each result?
Every result ends with a line naming the source and the date it was retrieved. Copy that date into your record next to your own check date. Registers change, so treat each result as a record of that day.
Is a supplier list check the same as advice?
No. It's a check of public register records from the Australian Business Register and ASIC. It isn't tax or legal advice. For a GST or withholding question, confirm with the ATO or your accountant.
