Before this change, sharing a project estimate required copying a link or entering an email address with no connection to who's actually on your team. There was no way to tell, at the moment of sending, whether the recipient had access to the project.
Estimates now go directly to members of your organization. When you click Send Estimate in the service request flow, a modal opens showing everyone on your team. You can search or filter the list by name to find the right person quickly, then select them — the row highlights to confirm your selection — and click Send Estimate to deliver it.
If the person you need isn't in your organization yet, the modal includes an Invite someone new form that expands inline. Fill in their details and submit the form to add them to your org and loop them into the estimate in one step, without leaving the modal or navigating to a separate Members page.
This means estimates are always tied to someone who has — or is being given — a seat in your organization, so there's no ambiguity about who received the estimate or whether they can access the underlying project. Once sent, a confirmation appears to let you know the estimate was delivered.
