We are delighted that you love working with BestInvoicing! Maybe you know some fellow entrepreneurs for whom BestInvoicing could also be interesting? Sharing your experience with BestInvoicing can now be profitable for you too ... If you invite a fellow entrepreneur via your BestInvoicing account for a free trial period and he/she moves to a paid subscription, you will receive **1 month of BestInvoicing for free**. The more companies you introduce, the more free months you will receive. From three referred companies that take out a paying subscription, you will receive a **permanent 20% discount** on your subscription. Other free months are added to that. A nice bonus, right? ## How Does It Work? At the top right-hand corner of the menu behind your email address you will find a "Recommend BestInvoicing" button (green icon). Clicking it will bring you to an overview screen. ![](/files/850TpIPBbqQPaT4P9KD9) You can invite a fellow entrepreneur by sharing a sign-up link or by sending an email with a specific sign-up link from the interface. On the left side, you'll see how much discount you've already collected. Easy! --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://support.onfact.eu/settings/my-subscription/recommend-bestinvoicing.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
