Finding and contacting vendors
They join your shortlist on the dashboard, with a status you move from Shortlisted to Contacted, Quoted and Booked, plus the quoted price, the deposit paid and a private note only you can read.
Saving a vendor puts them on the Saved tab of your dashboard. It is a tracker, not a list of hearts.

Your quoted price, deposit and notes stay private. A vendor never sees them.
What a vendor does see is a count: how many couples have them shortlisted, in touch, quoted and booked. A count of one or two is hidden from them, and your name is only shown once you mark them Booked, because at that point you have chosen them.
If a vendor later leaves the directory, your notes stay.
