To assign someone a page role to your facebook business page, log onto facebook, open up your business page, click settings (left menu), Page Roles, type their name (if they’re on your friends list) or their email address in the box, assign them their permissions from the dropdown i.e. editor, admin etc and click Add.

This will send the recipient an invitation (found in their notifications) and once accepted, they will be able to manage the page.

Annoyingly, often the person cannot be added this way as the Add box appears to be greyed out. If this happens, you will need to add the user via Business Manager instead.

1.  Go to business.facebook.com and select the business in question.
2. Click on “Business Settings” (left sidebar)
3. Under “Users” click on “People”
4. Click the blue button that says “Add.” You don’t need to type anything into the box next to it, just click on “Add.”
5. In the box that pops up, you can enter in their email address. Note: this can be any email address – whatever the user prefers.
6. Select the access you want them to have.
7. Next,  you’ll be able to select which Page or Pages you want them to have access to, and you’ll need to AGAIN select admin access in the far right column. Scroll down for this; it’s at the very bottom of the right column.
8. Click “Invite”
9. Make sure they check their email. They will not get a Facebook notification about this, it will ONLY come to email. They need to accept the invitation or they won’t have access.

Should you need to remove, revoke or change their page role status, just follow the steps above but instead of adding them, scroll down further to the Existing Page Roles heading and tap Edit next to their name.
