Action

Update Invoice

Tool to update an existing invoice. use when you need to modify the details of an invoice after it's been created.

Why this helps

Small reference corrections are easy to defer because the research and invoice edit live in different workflows.

  • Tie a verified reference correction to one existing invoice.
  • Reduce context switching between research and finance records.
  • Get a run report to support a quick confirmation.

Setup

Build it in a few focused steps.

  • 1Connect Tavily and Xero to Notis once through the portal.
  • 2Create an automation in the portal or ask Notis conversationally.
  • 3Write one instruction that requires a verified reference, identifies the exact existing invoice, and requests the correction.
  • 4Choose an incoming webhook trigger and a channel for run reports.
  • 5Test with a real low-risk reference fix and check the invoice in Xero.
