What it does

Before you install
Write tools create contacts and draft invoices or quotations, so confirm them before running. The server asks for your Lexware Office Public API key, which is stored per user on the provider's side. Free tier is limited to 100 tool calls per month; Pro is $9/mo or $90/yr per organization and is billed through a Stripe Checkout link returned by the upgrade tool, with no refund for the current period on cancellation.
