FAQ

How this task behaves

  • 01

    Can the AI change my invoices in Oyster?

    No. The AI can only read invoice and engagement data. It cannot edit, delete, or create any records in Oyster.

  • 02

    Does the AI handle the actual payroll payments?

    No. The AI only audits the data. You must still manage and execute all payroll runs through your standard Oyster workflow.

  • 03

    Can I ask about specific contractor names?

    Yes, as long as that information is contained within the engagement metadata provided by the tools.

  • 04

    Will the AI automatically fix errors it finds?

    No. The AI identifies the mismatches and presents them to you. You are responsible for making any corrections.

  • 05

    It uses the list of available invoices to identify the specific records you ask about.
