Can the AI automatically validate a shipping address before I calculate the tax?

Yes! Use the `resolve_address` tool with the full address string. Your agent will return the validated and formatted address, ensuring that the subsequent tax calculation uses the correct jurisdiction data.

How do I void a transaction that was recorded incorrectly?

Simply ask the agent to run the `void_transaction` tool with the specific transaction code and company code. It will instantly update the status in your AvaTax account.

Is it possible to check my company's tax nexus settings through the AI?

Yes. The `list_nexus_by_company` tool allows you to audit all active tax jurisdictions where your company is registered, ensuring you are collecting taxes where required.
