Person accounts and contacts to multiple accounts

Decide between business accounts with contacts, person accounts and Contacts to Multiple Accounts: what enabling person accounts commits you to (sharing, field security, storage, lead conversion, sites) and how direct and indirect account-contact relationships behave.

Official exam objective

What the exam expects

  • Choose between a business account with contacts, a person account and Contacts to Multiple Accounts for a given business model.
  • State what enabling person accounts commits the org to: no undo, the required org-wide defaults, inherited field-level security and double storage.
  • Predict person account behaviour in lead conversion, campaigns, cases, opportunities, merges, hierarchies and Experience Cloud sites.
  • Explain direct and indirect relationships, and what happens on disabling the feature, deleting an account, importing and reporting.
  • Know what the Account Contact Relationship object can and can't be customized with.

Key terms: business account (a company, with contacts that work for it); person account (an individual stored as one account plus one contact); primary account (the Account Name on a contact, its direct relationship); indirect relationship (any other account related through Contacts to Multiple Accounts); Account Contact Relationship (the object that stores each relationship).
