Invite a Guest to Your Money Mastery System

For the primary owner who wants to give a spouse, assistant, bookkeeper, accountant, or business partner structured access — using the correct in-app guest flow, not a Drive share.

Owner Action 5 min Guest Access Collaboration
This is for owners setting up access for someone else — not guests themselves.
Guest access uses a dedicated in-app flow, not a simple Drive share.
The guest must use the exact email you invite.
Sharing the Google Sheet alone does not fully authorize them.

Who You Can Invite

Spouse / Partner
Shared household finances and budgets
Assistant
Delegated data entry and uploads
Bookkeeper
Transaction review and categorization
Accountant
Period-end review and reporting access
Business Partner
Shared visibility into business finances
Co-owner
Full joint access with shared oversight

Before You Start

Confirm these three things before you open the guest menu. Click each item when you've verified it.

I know the exact email address the guest will use to sign into Google
I understand the guest should follow the guest flow, not the owner registration steps
I understand that sharing the Google Sheet alone is not enough

The Steps

1
Open the Money Mastery Menu Menu

From inside the workbook, open the top menu and navigate to:

Money Mastery → Manage Guests

Use the official guest-management area. Do not try to create access by inventing your own workaround, and do not tell the guest to use your own access key.

2
Add the Guest's Email Carefully Email

Enter the guest's email address exactly as it should be used for login. The guest flow keys off the email itself — if they open the sheet from a different Google account, the system may treat them as unauthorized even if the email is only slightly off.

Double-check all of these before submitting:

  • Spelling — no transposed letters
  • Dots and domains — name@domain.com not name@doomain.com
  • Work email vs personal email — confirm which one they'll actually use
  • Whether they will actually sign into Google with that address
3
Complete the Guest Invite Action Invite

Submit the guest invite through the in-app guest system. Depending on the flow and the build state, the system may:

  • Create a guest record tied to their email
  • Generate a temporary PIN or first-time access path
  • Send an email invite or prepare the access internally for guest setup

What matters most is that the invite is created through the correct menu and tied to the right email.

4
Tell the Guest What to Expect Comms

When you send a guest into the system, tell them two things:

  • Which email to use — the exact one you invited
  • Not to follow the primary-owner registration steps — they are not supposed to go hunting for an access key if they were invited as a guest

They should follow the guest-access path instead. Send them to the Guest First-Time Access article if they need a walkthrough.

5
Confirm Their Status if Needed Verify

If the guest does not get in successfully the first time, go back into Manage Guests and verify:

  • The guest was actually added
  • The email is correct
  • They are opening the sheet from the same invited Google account

This is often where the issue lives — not in the system, but in which account is open.

6
Remove or Revoke Access When Needed Revoke

If you no longer want someone to have access, use the Manage Guests area to remove them.

Do not assume that stopping communication or removing a shared Drive shortcut handles the full in-app access state. Use the guest-management flow directly.

What the Manage Guests Area Looks Like

Here's a representation of what you're working with inside the guest-management flow:

Guests only gain full access when they open the workbook from the invited email address.

Getting the Email Right

The most common reason guest access appears broken is a mismatch between the invited email and the one they're actually signed in with. Use this checklist:

Common Mistakes

Assuming Google Drive sharing is enough
It is not. The workbook and the app logic are not the same thing. A Drive share lets someone open the file — it does not authorize them inside the Money Mastery system. Both steps are required.
Inviting one email while the guest opens another account
This is the most common reason access appears broken. Invite exactly the Google account they will use to open the sheet — not their preferred email address if those are different things.
Telling a guest to use the owner access key
That puts them in the wrong flow entirely. Guests have their own entry path. The owner access key is not transferable and will not work correctly for a second person.
Forgetting to remove a guest when access is no longer needed
If you want access revoked, use the system's own guest-management path. Stopping communication or removing a Drive shortcut does not fully close the access state inside the app.

What Not to Click or Do

Do not send guests into the owner registration tutorial
Do not improvise access by pasting keys or sharing PINs casually
Do not assume a guest problem is "the system being weird" before checking the exact invited email
Do not use Google Drive sharing as a substitute for the in-app guest flow
What to Check When You're Done

You'll know this is set up correctly when:

  • The guest was added through the official guest flow
  • The guest knows which email to use
  • The guest is not trying to register as the primary owner
  • You can see or confirm the guest's status from the system side if needed
"Guest access works best when it's treated like a real workflow, not a casual share. The cleaner you are about who was invited, which email they should use, and what role they actually have, the smoother the whole collaboration side of Money Mastery becomes."
