The rule that prevents every hostage situation.
One sentence of policy saves businesses from the most common mess I see.
You are always the primary owner
Your business's profile should be owned by YOUR Google account — not your agency's, not your web guy's, not an employee's personal Gmail. Helpers get Manager access. Always.
Managers can do almost everything
A Manager can edit info, reply to reviews, add photos, run the day-to-day. The only things they can't do are delete the profile or control who owns it — which is exactly the point.
Agencies come and go; the profile doesn't
When you leave a provider, you should be removing THEIR access, not begging for yours. If a provider insists on primary ownership, that's not a workflow — that's a leash.
Buying a business? The profile is an asset
Years of reviews are part of what you paid for. Put the profile transfer in the closing checklist alongside the keys and the bank accounts — it's worth more than the sign out front.
