Your partner is already using Hemma for the build. Or your architect has set up the project. Either way, they invited you. Now there is an email in your inbox and you are wondering what to do next. Short answer: click the button. Hemma walks you through the rest.
The subject line tells you who invited you, in the form "their name invited you to a project on Hemma". The email is short on purpose. A heading that says "You've been invited", one paragraph, and a green "Accept invitation" button.
You have seven days to accept. After that the link stops working and the person who invited you needs to send a new one. If the button doesn't render in your email client, the email also includes a plain-text link you can copy and paste.
The link takes you to a page on Hemma that shows you the name of the project and the name of the person who invited you. From there it depends on whether you already have a Hemma account.
You don't have an account yet. Hemma asks you to sign in first. You can use a magic link (Hemma sends a one-tap login link to your email) or sign in with Google. Either works. Once you're signed in, the invite page comes back with the Accept button ready.
You already have an account. You see the project name, who invited you, and an Accept button. One tap and you're in.
Your profile is missing your name. First time accepting any invite, Hemma might ask for your first and last name in a small modal. This is so your partner sees who is who in the team list, not just an email address. Type both, save, and the acceptance continues automatically.
Hemma uses a flat membership model: once you accept, you have the same access as everyone else on the project. You see every document, every invoice, every quote, every plan. Your partner uploads a contractor email, you see it on your home screen the next time you open Hemma. You add a note, your partner sees it.
There are no read-only roles, no per-folder permissions, no "you can see this but not that". The thinking is simple: a build is a shared project. The people on it are in it together.
The one exception is ownership. The person who first created the project is its owner. They can invite and remove team members, and they are the only one who can delete the project. Everyone else can leave the project at any time, but can't change the team.
A few things can go wrong with an invite link, and Hemma tells you which one it is.
In all three cases, the page tells you what's wrong and gives you a way forward. Your inviter can always send a new invite — it takes them about ten seconds.
