Checking an ABN means confirming the number on an invoice is valid, active and, if GST is charged, registered for GST.
Before you start
- Vendor master access
The Dynamics 365 Finance way
Where to find it: Vendor, tax registration and TPAR
- Record the ABN on the vendor.
- Run the TPAR data collect and review the Payees list.
- Use the Statement by supplier information if a contractor has no ABN.
Limits in Dynamics 365 Finance
- The Microsoft help describes no ABN Lookup check.
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 Dynamics 365 Finance.
- Fix the vendor record or query the vendor, then approve.

What Pulsify does not do here
- If the ABN lookup is not available, Pulsify flags that it could not validate.
Common mistakes
- Assuming the ABN is checked against the ABN register, when the Microsoft help describes no such check.
- Leaving the ABN blank on a contractor, then finding them on the TPAR Payees list without one.
