Who each option is really for
Clientjoy
Clientjoy is generally aimed at agencies, consultancies and independent professionals who win work through proposals and keep it through relationships. The lifecycle it describes runs from enquiry to proposal to invoice to renewal, which is a narrower and more specific path than a general sales pipeline. Businesses that recognise themselves in that path often find a focused tool easier to adopt than a CRM they must bend into shape.
Zoho
Zoho is not a single product but a family of business applications spanning sales, finance, projects, support and more, available individually or in bundles. The attraction is consolidation and a large partner network. The cost is that you are choosing a platform, which means deciding which applications to adopt, who administers them, and how much configuration you are willing to fund before the system reflects how you work.
