Add Invoice Crowd to Claude or ChatGPT
Open How to Connect on the Integrations page and copy the Connection Address. In Claude, add it as a custom connector; in ChatGPT, create a connector with it. Your AI app then opens Invoice Crowd's own Allow Access page, where you sign in, choose one business and allow access. Your password never goes to the AI app.
