Zoho CRM provides a considerable amount of flexibility, but flexibility needs to be used carefully. One of the most important decisions is how different types of information should be represented and connected.
Contacts should normally represent people. Accounts should represent organisations. Deals should represent potential or confirmed business. Other records, such as properties, policies, memberships, sites, equipment or contracts, may require their own modules.
When fundamentally different things are combined within the same module, duplication and reporting problems quickly develop. It can also make integrations with applications such as Zoho Books considerably harder.
A well-designed data structure may not be the most visible part of an implementation, but it determines how reliable and adaptable the CRM will be in the future.
