Participants

Adding Participants

Tap Add Participant from the Participants tab. Pick someone from your contacts or create a new one. From the participant form you can:

Set their role (defaults to the tracker's default role)
Configure Opted-Out Categories (on even-split trackers without category splits)
Adjust daily presence weights (on prorated trackers)

Sharing Your Tracker

Only the tracker owner can invite others. To bring in someone who doesn't have Tabello yet, first add them as a participant — you can create a contact for them right from the participant form, no email required. Then tap Share in the tracker toolbar. There are two ways to invite them:

Open share link. Toggle on a single link that anyone can use to join the tracker. When someone opens it, they pick which unregistered participant they are, and from then on they appear as that person in your splits. Convenient for groups, but anyone with the link can claim any unregistered participant — share it only with people you trust.

The open link is only available when the tracker's default role is something other than No access. Change the default from tracker settings to enable it.

Personal invitations. For tighter control, send a personal link to each unregistered participant. Each link is tied to one participant, so there's no ambiguity about who joins as whom. Use Copy link to grab it for any messaging app, or Email to send it directly when the contact has an email.

Unregistered participants with the No access role can't be invited individually — edit the participant to give them a role first.

Roles

Roles control what someone can see and do.

Role Permissions

	Contributor	Reader	No Access
View tracker & expenses	Yes	Yes	No
Add expenses	Yes	No	No
Edit/delete own expenses	Yes	No	No
Manage own settings	Yes	No	No
Record payments (own unit)	Yes	No	No

The tracker creator is always the Owner with full control — manage participants, modify settings, change roles, edit any expense, record any payment. Owner cannot be assigned to other participants.

No Access means the participant exists for expense allocation only. They can't view or interact with the tracker, even if they have a Tabello account.

The tracker's default role applies to new participants unless overridden per-participant. Changing the default role is not retroactive — existing participants keep their current role. The owner can change any participant's role at any time from the Edit Participant screen.

Removing a Participant

Only the tracker owner can remove a participant. Here's what happens when you do:

Expenses created by or paid by that participant are deleted
Expenses where they were the only remaining participant are deleted
Other expenses: the participant is removed and allocations are recalculated among remaining participants
If the tracker uses Category Splits, shares are proportionally redistributed
