To add a client to a trip in Plan Harmony, go to the trip's Settings page, scroll to the Trip Guests section, click Add Client, and choose either the From Clients tab to select from your agency roster or the By Email tab to invite by email address. Clients can then view the itinerary, receive updates, and collaborate on planning depending on their assigned role.
Plan Harmony gives agency planners three ways to add clients:
| Method | Best For | Account Required? |
|---|---|---|
| From Clients | Returning clients already in your roster | No |
| By Email | New clients or anyone with an email | No (invitation sent) |
| Placeholder Guest | Children, plus-ones, unnamed travelers | No |
If you've already built up your client list in Plan Harmony, adding a client to a trip takes just a few clicks.
Clients already assigned to the trip appear with an "Assigned" label and cannot be added again.
Use this option when the person you want to add isn't in your client list yet, or when you prefer to invite by email.
In both cases, Plan Harmony automatically creates a client record in your agency roster if one doesn't already exist. This means you won't need to manually add them to your client list — they'll be there for future trips.
Sometimes you need to account for a traveler who doesn't have an email address — a child, a plus-one, or a group member whose details you'll collect later.
Placeholder guests appear in the Trip Guests list but do not receive any notifications or emails. You can edit a placeholder guest later to add their email address, which converts them to an invited guest and sends them an invitation to join the trip.
After adding clients, you can manage them from the Trip Guests section on the trip's Settings page. Each guest shows their name, email, and role.
Clients added to a trip are assigned the editor role by default, which lets them:
Agency planners and trip owners retain full control over the trip, including the ability to add or remove members.
Your agency's client list grows automatically as you invite people to trips. Every email invitation creates a client record if one doesn't already exist.
You can also build your client list proactively:
A well-maintained client list makes it faster to add returning clients to new trips — just search and click from the From Clients tab.
