Checking an ABN means confirming the number on an invoice is valid, active and, if GST is charged, registered for GST.
Before you start
- Contacts access
The MYOB Business way
Where to find it: Contacts > All contacts > open the supplier
- Enter the supplier's ABN on the supplier.
- MYOB checks the ABN and shows its status.
- Click the status to see the detail, or click Open ABN lookup website.
Limits in MYOB Business
- Check GST status and use GNR or ABN tax codes as needed.
The Pulsify way
- Forward the supplier's invoice to Pulsify.
- Pulsify checks the ABN against the ABR. It flags an invalid ABN, a missing ABN and an ABN not registered for GST when the invoice charges GST.
- It also flags an ABN that differs from the one on the supplier record in MYOB Business.
- Fix the supplier record or query the supplier, then approve.
Pulsify connects to MYOB in one click. Approved bills are created in MYOB with the source file attached.
What Pulsify does not do here
- If the ABN lookup is not available, Pulsify flags that it could not validate.
Common mistakes
- Leaving the ABN off the supplier, so no status shows on the bill.
- Not choosing the GNR or ABN tax code when the supplier is not registered for GST or has no ABN.
