If ArchiBoard helps you, it can help your colleagues too. Share your invitation link. Your colleague gets Pro for 14 days straight away, and you get a month of Pro once they start working.

1. **Open billing.** Open «Profile settings» → «Billing» and find the «Invite a colleague» block.
2. **Copy the link.** In «Your invite link», click «Copy» and send the link to your colleague.
3. **Your colleague signs up.** Your colleague signs up with your link and gets 14 days of Pro straight away.
4. **Get a month of Pro.** When your colleague creates a project with at least 5 items, you get a month of Pro.

- The block shows how many people signed up with your link and how many months of Pro you have earned.
- You can send the link to several colleagues.
