Checking an ABN means confirming the number on an invoice is valid, active and, if GST is charged, registered for GST.
Before you start
- Accounts Payable subscription
The Sage Intacct way
Where to find it: Accounts Payable > Setup > Vendors; TPAR tab
- Enter the supplier ABN in the tax identification fields on the supplier record.
- Look the ABN up on ABN Lookup by hand.
- If you report contractor payments, tick Enable TPAR on the Additional information tab. The TPAR includes the supplier ABN.
Limits in Sage Intacct
- No live ABN Lookup check inside Intacct was found in the help.
- The TPAR report shows tax withheld when an ABN was not provided.
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 vendor record in Sage Intacct.
- Fix the vendor record or query the vendor, then approve.
Pulsify connects to Sage Intacct. We set up the connection for you.
What Pulsify does not do here
- If the ABN lookup is not available, Pulsify flags that it could not validate.
Common mistakes
- Typing the ABN into the wrong field.
- Skipping the manual ABN Lookup because the field accepts any value.
