Mandatory Migration
Oracle is replacing Vertex. Your US payroll tax engine must migrate before 26B.
We make sure nothing breaks.
The USOPTE transition is mandatory for all Oracle Cloud HCM customers running US payroll. Payaptic's Transition Assurance package ensures your tax calculations, custom objects, and compliance configuration survive the migration intact.
Oracle's timeline is fixed. Yours doesn't have to be at risk.
