After a hand-over, clients can post through their own Google account

When an agency hands a business over, the client can now move Google Business Profile posting to their own Google account.

• On Google, make the client the profile's primary owner
• In LotsBusiness, the client opens the business's Google tab and clicks Use my Google account
• LotsBusiness checks with Google that the client manages the profile, then posts and updates go through the client's account

An agency that keeps manager access can keep posting until the client switches. https://lots.business/agencies
