Google Workspace offers four plans, one of which is the Business Starter plan. Questions about compliance are addressed in the FAQ section on the Google Workspace main page, not individual plan pages.
Google Workspace claims it supports customers’ compliance with HIPAA. Customers who use Google Workspace and its products to process and store PHI will need a Business Associate Agreement (BAA) with Google. The BAA process is detailed in the platform’s online Help Center.
The website doesn’t mention the BAA being limited to certain plans. However, when you compare the plans in detail, you can see that the three Business level plans — Starter, Standard, and Plus — are missing several of the security and management functions needed for HIPAA compliance. These functions are available only in the Enterprise plan.
