How to add clients to a project
In Upbase, you don’t invite clients directly to projects.
Instead, you invite guests who belong to a client.
This makes Upbase more flexible:
- One client can have multiple guests
- You can invite only the specific guests you want to each project
- This helps keep things private and organized
In short:
Clients group people. Guests join projects.
In Upbase, you add clients to projects by inviting their guests.
Click the project name at the top, then select People from the dropdown.

Click Invite guests:

From here, you can invite existing guests or new guests.
1/ Invite existing guests
You can add guests who are already in your workspace.
- Use the Guests field to search by guest name
- Use the Company field to search by client name and filter guests from that client

Add all guests from a client
If you want everyone from a client to join the project:
- Select the client in the Company field.
- Click Add all guests.
This selects all guests from that client at once.

2/ Invite new guests

Add a new guest to an existing client
- Enter the guest’s name and email.
- Select an existing client in the Company field.
- Send the invite.
Add a new guest and a new client at the same time
- Enter the guest’s email address.
- Type a new client name in the Company field and press Enter.
- Send the invite.
Upbase will create the client and invite the guest in one step.
Inviting guests from multiple clients
You can invite guests from different clients to the same project.
When you do, that project will appear under Projects for each client on the Client Management page.
Guests are usually client users, but they can also be freelancers or external contractors.
If needed, you can invite them to client projects the same way.
This makes it easy to work with multiple clients — all in one project, without mixing access.
