Hear why customers like Orica choose ONESOURCE Indirect Tax Determination
ONESOURCE Indirect Tax Determination independently validates GST and triggers workflow, where OITD results vary from the invoice document. This allows the tax team to identify and address issues at the time of invoice processing, rather than at the GST or VAT return preparation stage.
