Install in three steps

Create a free account at 0n3.app and connect QuickBooks: paste a key or sign in through a door. It lands in your vault, encrypted.
Open 0n3.app/install, pick your AI. A key is made for that AI alone; copy the line it gives you.
Ask your AI: whoami. It answers with your connected services. Then ask it to create an invoice in QuickBooks.
