Can I check if an invoice has been paid through the agent?

Yes. The `list_accounting_invoices` tool allows your AI agent to see the current status of all invoices, including whether they are 'PAID', 'SAVED' (unpaid), or still in 'DRAFT' status.

How do I add a new client to my Wave account using chat?

You can use the `create_accounting_customer` tool. Just provide the customer's name and email address, and your agent will register them in your Wave business instantly.

Can I delete a draft invoice if I made a mistake?

Yes. The `delete_draft_invoice` tool allows you to permanently remove unfinalized draft invoices. Note that once an invoice is approved (SAVED) or paid, it cannot be deleted through this specific tool.
