# How to check a vendor's ABN in MYOB Acumatica

Look up the vendor's ABN on ABN Lookup, then save it in MYOB Acumatica. Check the status is active, the name matches and the supplier is registered for GST.

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 access

## The MYOB Acumatica way

Where to find it: Vendors (AP303000) > TPAR Settings

1. Open the vendor on Vendors (AP303000). In TPAR Settings tick Track for TPAR.
2. Enter the ABN to use for the TPAR.
3. Optionally set a TPAR Location for an ATO-registered address, contact and banking details.

## Limits in MYOB Acumatica

- The ABN in TPAR Settings is used for TPAR reporting only.
- No ABN lookup is described in the help.

## The Pulsify way

1. Forward the supplier's invoice to Pulsify.
2. 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.
3. It also flags an ABN that differs from the one on the vendor record in MYOB Acumatica.
4. Fix the vendor record or query the vendor, then approve.

Pulsify connects to MYOB Acumatica. 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

- Assuming the ABN in TPAR Settings is checked. It is used for TPAR reporting only.
- Skipping Track for TPAR on a contractor, so their payments miss the TPAR report.
