An ecommerce platform
A storefront platform exists to present products, take payments and process orders. Its natural buyer runs an online catalogue, cares about page performance, checkout conversion and fulfilment, and usually works with a developer or an agency. Customer data accumulates as a consequence of transactions rather than as the purpose of the system.
Zoho
Zoho is a family of business applications rather than one product, covering sales, finance, support and more. Its natural buyer wants to consolidate several business systems with one vendor and has, or will appoint, someone to administer the configuration. On the sales side the purpose is relationship management: who owns a lead, what stage it is at, and what happens next.
