Write off one or more unpaid transactions. Use this for transactions that will not be collected (e.g., bad debt).
AI agents use write_off_transaction to commit financial operations through Ontraport MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Writing off transactions is a financial action that permanently marks debts as uncollectable, affecting financial records and revenue recognition. This is irreversible in accounting terms and directly impacts financial obligations, placing it firmly in the Financial category with critical severity due to the potential for large-scale financial record manipulation by an AI agent.
From the tool's definition 'Write off one or more unpaid transactions' and 'transactions that will not be collected (e.g., bad debt)'
