Invoice fraud checks in MYOB Acumatica for builders

Why it matters for builders

If a subcontractor does not quote an ABN on a business invoice, you generally must withhold tax at the top rate from the payment unless an exception applies. That is a cash and compliance risk on every new trade.
Businesses with 50% or more income from building and construction services must lodge a TPAR, so subcontractor details have to be accurate through the year.
